It has an embedded investment platform that aims to increase the income of liquidity providers. It is deployed simultaneously on the three leading chains: Ethereum, Huobi HECO, and Binance Smart Chain.SashimiSwap utilizes funds in the platform's liquidity pool to execute automatic trading strategies. In addition to the fee incomes similar to other decentralized exchanges, users of SashimiSwap also receive considerable investment earnings. You can think SashimiSwap as a spot forex exchange, and it saves part of the deposited funds in a bank to earn interest. ![](/files/-MOVb6fLtAoY2d0LwWKu) SASHIMI is the token on the SashimiSwap platform, which is distributed 100% through liquidity mining, without any pre-sale, pre-mining, and team shares. Holders of SASHIMI token are able to participate in platform governance and receive SashimiSwap dividends through staking. platform income now includes transaction fees, income from liquidity investment, and service fees from Vaults, with more sources of income under development. ## Core components ![](/files/-MOVbZG86ckaWTDCyx0v) ### Core components * SashimiSwap Exchange: a decentralized trading platform using AMM transactions (part of the funds are invested by Investment) * SashimiSwap Investment: an asset management platform built into the Exchange. Idle funds are invested through different financial products, and the investment income is used to buy back SASHIMI, which is then transferred into the Sashimi Bar. * SashimiSwap Farms: a liquidity mining platform used for liquidity incentives, supporting ordinary mining and double mining * SashimiSwap Vaults: an aggregate financial management platform that invests the assets staked by users through different platforms to obtain the highest yield * SashimiSwap Governance: ecosystem governance platform that allows the community to decide the development of SashimiSwap through multi-signature. ### Other related components * Sashimi Bar: Users can obtain Sashimi Bar's SASHIMI income by staking SASHIMI (including 25% income from Investment, 0.05% fee income of Swap (not realized yet)) * Treasury: Treasury's funds include part of the fees charged by Vaults and 75% of the income from Investment. The funds can be used for community building, project cooperation, etc., or they can be burnt. Part of the funds will be put into the Marketing Fund to motivate and support the community’s marketing plan. The specific distribution rules are determined by the community (for transaction information, see Treasury Record ). * Dev Fund: Part of the fees charged by Vaults will be put into the Developer Fund for development (for transaction information, see [Dev Fund](https://etherscan.io/address/0x0FaEF44d1373F6fdE75926E4564baB5B2d645944)). ## Component architecture and collaboration SashimiSwap builds a complete DeFi integrated platform through the interaction between multiple components. Users can play the roles of traders, liquidity providers, investors, etc. in the SashimiSwap ecosystem. ![](/files/-MOVcEcgfEA_Vcf2-tvu) ## Project Features * High asset utilization and high yield. It is able to use funds in the platform's liquidity pool for automated strategic investment * A fairer token distribution mechanism encourages community members to actively participate in governance * Vaults will use decentralized exchange funds for financial management through contracts to offer users high returns * Comprehensive on-chain governance, decentralized control and development from the start # 1.2 SashimiSwap Exchange ## Introduction SashimiSwap Exchange is SashimiSwap's decentralized trading platform, which uses the popular AMM (Automated Market Maker) mechanism in decentralized exchanges represented by Uniswap for trading. The principle is to use the CFMM (Constant Product Market Maker) model to establish a trading market, and determine the price range of the two tokens according to the available quantity (liquidity) of each token through the definite product function x∗y=k . Since the relative prices of the two tokens in a transaction pool are changed by trading (following the rules of the definite product function), the difference between the token price in the trading pool and the external price will create opportunities for arbitrage. This mechanism ensures that the Token price is always in line with the market settlement price. In SashimiSwap Exchange, the following two functions are provided: （1）Add / Remove Liquidity： Users put two tokens of equal value in the transaction pair into the transaction pool and obtain the corresponding LP Token. The LP Token represents the redemption voucher of the assets added by the user in the transaction pool, allowing users to redeem their assets at any time. （2）Swap： Users are allowed to exchange any ERC-20 Token into another ERC-20 Token through the transaction pool. At the same time, users need to pay a 0.3% transaction fee. ## Tutorial ### Tutorial 1: How to redeem Token?

Users can stake LP Token to get SASHIMI as mining rewards. ## Farming Strategy ![](/files/-MURwtQntkZN4wPyl2BI) Users participate in mining by staking LP Token (currently support LP Tokens such as UNI-V2 LP, SLP, SALP, etc.) in the corresponding mining pool to earn SASHIMI. The released SASHIMI will be distributed to each mining pool according to a specified ratio, and SASHIMI rewards will be distributed in each mining pool according to the proportion of LP Token staked by users. #### Contract information: MasterChef contract {% embed url="" %} ## SASHIMI token release rules for mining rewards SASHIMI is the platform token of SashimiSwap. Farms use liquidity mining to generate SASHIMI tokens. SASHIMI tokens are 100% generated based on liquidity mining, without any pre-sale, pre-mining and team distribution. SASHIMI holders can participate in platform governance and obtain dividends from the platform. Platform income now includes transaction fees, income from liquidity investment, and Vault fee income. Below is the SASHIMI release plan: The total supply of SASHIMI is 100M, and the distribution will be reduced according to the rules shown in the figure below until the total distribution reaches 100M. ![](/files/-MOVh2L_s6zyb-8vRaon) ## Tutorial on mining Step 1: With the wallet connected, enter the SashimiSwap Exchange add liquidity page () to add liquidity, at this time you will get the SALP Token of the trading pool; (If the mining pool is an LP Token of other protocols, you need to go to the corresponding platform to add liquidity to obtain the LP Token) Note: For how to add liquidity, please refer to "Tutorial 2: How to add liquidity?" in the document "1.2 SashimiSwap Exchange". Step 2: Enter the Farm page of SashimiSwap （） to select the mining pool and click "Select" (if there is no asset supported by the mining pool, you can click "GET LP" to enter the designated platform to add liquidity to obtain LP Token) ![](/files/-MOVhQkNmmu242EQbDZE) Step 3: After clicking "Select", you will enter the LP Token details page. Now, you need to authorize the contract before mining. Click "Approve" to authorize and confirm the transaction in the connected wallet. ![](/files/-MOVha3CmNAq6h-nrST2) Step 4: After completing "Approve", click "+", type the amount of LP Token to be staked in the pop-up window, click "Confirm", and confirm the transaction in the connected wallet to complete staking. ![](/files/-MOVhlDfy7xf9sERRBgO) ![](/files/-MOVhtal7n8DZE9pPb9z) Step 5: After the LP Token is staked, the Farm will calculate and distribute SASHIMI mining rewards based on the amount of staked LP Token in the current mining pool assets. The SASHIMI income generated by mining will be shown on the "SASHIMI Earned" card on the left side. Click "Harvest" and confirm the transaction in the connected wallet to transfer the SASHIMI income into the wallet. ![](/files/-MOVi0ycbSmX__IXHf-l) Step 6: When withdrawing the staked LP Token, click "Unstake", enter the amount of LP Token to be withdrawn in the pop-up window, click "Confirm", and confirm the transaction in the connected wallet to complete the withdrawal. ![](/files/-MOViD7wCtOqdAElnHaa) ![](/files/-MOVj-PAh41_-v0p66sE) # 1.4 Sashimi Lending ## Introduction Sashimi Lending is an algorithmic interest rate protocol of collateralised loan market. Sashimi Lending smart contract defines the interest rate model for user deposits and borrowings through algorithms. Users can deposit assets in the market, or collateralise assets to borrow from the market at any time. Depositors can get interest income, while borrowers need to pay an interest. The platform provides deposit and borrowing services with dynamic and floating interest rates. Sashimi Lending's interest rate is determined by the supply-demand relationship of the market, the protocol provides fast and efficient transactions by cutting middlemen, removing borrowing time lag and operation restrictions. Initially, Sashimi Lending will launch eight Supply and Borrow markets, users participating in every markets can receive $SASHIMI reward, which will be allocated to each market based dynamically on the proportion of interest generated in that market. ![](/files/-MOZPI_QeAz2T5tUh9c9) ## **Contract Information** Lending Contract：[https://etherscan.io/address/0xB5d53eC97Bed54fe4c2b77f275025c3fc132D770]() Pools Contract: | Pool | Reward Token | Contract Link | | --------- | ------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------- | | slETH | SASHIMI | | | slDAI | SASHIMI | [https://etherscan.io/address/0x2918231F262f764DbB5753A95BD7684fDB313ea4]() | | slUSDC | SASHIMI | [https://etherscan.io/address/0xBbCc16ab7937469bB1E72337427678e7E701b9Ea]() | | slUSDT | SASHIMI | [https://etherscan.io/address/0x2394DE3827e233298fff0FdF6Aa261070BFE013d]() | | slWBTC | SASHIMI | [https://etherscan.io/address/0x09a7fB5E4499e61C7cF53aCB8Df7B2a8e4Fb36F9]() | | slYFI | SASHIMI | [https://etherscan.io/address/0x6DDBcBAa13bDE44a406780E298721483D684F1B0]() | | slELF | SASHIMI | [https://etherscan.io/address/0xDDDAf1a95e57F7a74D85F366936F8a2ABBc86b45]() | | slSASHIMI | SASHIMI | | ## Sashimi Lending interest rate model ### **1.Generation of deposit interest** After depositing the underlying assets, depositors can get a certain amount of slToken, which can be used to exchange for the underlying assets. The exchange rate of slToken to the underlying asset will increase over time after the deposit. The increased part in exchange rate is the interest earned by the depositor. The more borrowings on the platform, the faster the exchange rate increases. ### **2.Exchange rate of slToken** The exchange rate of slToken is calculated according to the following data (taking Lending USDT as an example) * totalCash= The total amount of Underlying Asset that has been put into the smart contract but has not yet been borrowed * totalBorrows = The total amount of outstanding loans (including accrued interest) * totalReserves=Total amount of reserves ( part of payable interests is used as reserves) * totalSupply=The total amount of slToken received by all depositors *ExchangeRate =（totalCash+totalBorrows-totalReserves）/ totalSupply* ### **3.Utilization Rate** Utilization rate refers to the proportion of Underlying Assets borrowed out of total Underlying Assets: *UtilizationRate =totalBorrows /（totalCash+totalBorrows）* ### **4.Borrow Rate** In the Sashimi Lending interest rate model, the borrow rate is calculated as the dynamic annualised interest rate that the borrower needs to pay. It will be affected by the following factors: 1.Base Rate 2.Utilization Rate 3.Multiplier *BorrowRate = UtilizationRate \* Multiplier + BaseRate* ### 5.**Supply Rate** Supply Rate is the annualised interest rate that the depositors can receive. It will be affected by the following factors: 1.Borrow Rate 2.Utilization Rate 3.Reserve Factor *SupplyRate≈ BorrowRate \* UtilizationRate \*（1 - ReserveFactor）* In the Sashimi Lending interest rate model, the Base Rate, Multiplier, and Reserve coefficient of each token may be different, but they are all constants in the smart contract and will be disclosed in the contract code. Admins are authorised to modify these constants in smart contract, the communities can propose adjustments as they see fit, and any adjustments can be found openly and transparently on the blockchain. ## Liquidation rules The price of collateralised assets will fluctuate. When the value of collateralised assets of the borrower is insufficient to pay the outstanding loan due to price fluctuations, account liquidation will be triggered. The collateralised assets will be sold by the liquidator at an agreed discount price to repay the loan. The price discount is an incentive for the liquidator. The liquidation incentive is a constant in the smart contract. ## Sashimi Lending Tutorial ### Sashimi Lending #### 1. User Assets * Supply balance = User's deposit + Interest earned. * Borrow balance = User’s borrowing amount + User's payable interest * Net APY = Net Annual Interest Rate * Borrow Limit = The percentage indicates the healthy level of user account. The account is healthy when the percentage is low. If 100% of the borrowing limit is hit, the liquidation will be triggered. ![](/files/-MOfUigSFMdsUPsJCeUJ) #### 2. Markets In the 'Supply' and 'Borrow' lists, the Supply Market and the Borrow Market of each asset is displayed. Users can deposit to the Supply Market or borrow from Borrow Market. ![](/files/-MOfUn7zPySK1rXZHjul) ### How to use Sashimi Lending #### 1. Connect Wallet Take MetaMask as an example: Open the lending page, click "Unlock Wallet" in the upper right corner. After the pop-up window appears, select the wallet you want to use. After the connection is successful, you can check wallet information by clicking the address tap in the upper right corner. ![](/files/-MOZdxQchb-3baVWfdQx) ![](/files/-MOZc7ksVHA4fDA149OL) #### 2. Deposit Assets Select the token to deposit. Take $SASHIMI as an example, click SASHIMI, enable the supply, enter the amount to be deposited in the pop-up window. Then, click 'Supply' and confirm the transaction in the connected wallet. Note: the smart contract needs to be authorised through the enabling pop-up window. After successful deposit, interest will be accumulated over time according to supply APY. ![](/files/-MOZNG-DEVq8KikYxapH) ![](/files/-MOZNNLx85EH5Ld1g-XU) #### 3. Collateral Users can enable or disable the collateral through the switch of the asset list. After pledge, the Borrow Limit will change accordingly (Borrow Limit = Deposit Token Value \* Loan to Value ratio). Users can borrow money only after deposited collateral. Collateral is used to ensure the user has enough assets to repay the loan. If the outstanding loan exceeds the borrow limit, liquidation will be triggered. Again, take $SASHIMI as an example: find SASHIMI in the supply market and click "Collateral" to enable the collateral feature. Then, Click "Enable SASHIMI as Collateral" in the pop-up window to authorize, and confirm the transaction in the connected wallet. After the transaction is completed, the SASHIMI collateral switch will be turned on. If there is any SASHIMI deposit, the "Borrow Limit" percentage will increase accordingly. ![](/files/-MOZcIJ3JoCs2ZVIFBmA) ![](/files/-MOZNjL5GvjkvZ59G0re) Take $SASHIMI as an example, there will be two scenarios when disabling collateral: Scenario 1: If the user account has no outstanding loan, or the disabling of collateral will not trigger liquidation, click the switch tap in the "Collateral" column, and authorize by clicking "Disable SASHIMI" in the following pop-up window. After disabling, the switch will be turned off, and if there is SASHIMI deposit, the "Borrow Limit" percentage will be reduced accordingly. ![](/files/-MOZSz8vvSINas_5sH_1) Scenario 2: If disabling of collateral will trigger the liquidation, the switch cannot be turned off. ![](/files/-MOZShi13GeHtmqPSTzO) #### 3. Borrowed Assets Take SASHIMI as an example: click SASHIMI, enter amount in the borrow pop-up window, click "Borrow", and confirm the transaction in the connected wallet to complete the borrowing. After successful borrowing, interest will be accumulated over time according to Borrow APY. Note: you must deposit assets as collateral before borrowing assets, otherwise you can't take loan. ![](/files/-MOZTE6M4GpXjfdTV7u8) ![](/files/-MOZTYdTZB4wtYJwczUd) #### 4. Withdrawal Taking the withdraw all or part of SASHIMI as an example, users can click SASHIMI and select "WITHDRAW" tab in the deposit pop-up window. Then, enter the withdrawal amount, click the "WITHDRAW" button and confirm the transaction in the connected wallet. Note: You can withdraw the principal and interest earned at any time. The maximum withdrawal amount = deposit amount - outstanding loan amount / Loan to Value ratio. That is, the collateral cannot be withdrawn. ![](/files/-MOZOhS3wmecpX4jyvPv) ![](/files/-MOZOnbd33_8VH8ESsrF) #### 5. Repayment Taking the repayment of all or part of USDT as an example: click USDT and click the "Repay" tab in the repayment pop-up window. Enter the repayment amount and click "Repay", confirm the transaction in the connected wallet to complete the repayment. Note: You must enable the smart contract first before you supply or replay. You can repay at any time, your repayment will include principal and accrued interest. ![](/files/-MOZOtDikl46hnnQ1Fzw) ![](/files/-MOZP-MAnNLl_FIYgx1t) # 1.5 SashimiSwap Investment ## **Introduction** ![](https://uploader.shimo.im/f/AL60wBYiRjTe7aJb.png!thumbnail) SashimiSwap Investment is an asset management module built into Sashimiswap Lending. It will invest part of the assets (≤90%) in the liquidity pool with stable returns and minimum risks. Some profits from SashimiSwap Investment will be used to buy back SASHIMI and ETH through Exchange (DEX). 25% of the profits from SashimiSwap Investment will buyback SASHIMI and will be transferred to the Sashimi Bar Contract (check here: [SashimiBar](https://etherscan.io/address/0x6ed306DbA10E6c6B20BBa693892Fac21f3B91977)), the remaining 75% will buyback ETH and will be sent to Treasury (check here: [Treasury Record](https://etherscan.io/address/0x84ee348617563944ffd4a23843e086a7dc0224f3#tokentxns)). Users can obtain this part of the profits by staking the SASHIMI Token in the Sashimi Bar. It also allows users to redeem their staked SASHIMI at any time. (Staking SASHIMI will receive xSASHIMI as redemption voucher.) ## **Contract Information** Investment Contract： Pools Contract: | Pool | Reward Token | Contract Link | | ---- | ------------ | -------------------------------------------------------------------------- | | ETH | SASHIMI, ETH | ​ | | DAI | SASHIMI, ETH | | | USDC | SASHIMI, ETH | ​ | | USDT | SASHIMI, ETH | ​ | | WBTC | SASHIMI, ETH | | | YFI | SASHIMI, ETH | | | ELF | SASHIMI, ETH | | ## Tutorial Step 1: Open the Investment page (); When the wallet is connected, click "Rebalance" to invest the corresponding assets according to the investment proportion, and confirm the transaction in the connected wallet; (anyone can do it) In each pool, “Deposit” means the amount of assets being invested. “Supply Profit“means interest yield on deposits. “Farm Profit“means farming yield. “Basic Reserve Ratio” means the minimum required reserve ratio in Exchange that cannot be invested. "Actual Reserve Ratio" means the current actual reserve ratio; “APY” means the annual percentage yield（Supply APY + SASHIMI APY）. ![](/files/-MQQYnMnOr2GLBdvpVLQ) Step 2: If you want to get your returns back, Click "Harvest" and confirm the transaction in the connected wallet to get the returns. (Anyone can do this) The profits will be automatically used to buy back SASHIMI/ETH and redistributed to Sashimi Bar and Treasury in proportion. ![](/files/-MOVm4HLdphzdvrdjhUt) # 1.6 SashimiSwap Vaults ## Introduction SashimiSwap Vaults is SashimiSwap's assets management platform. Vaults invest the assets staked by users to conduct non-risky assets management through other DeFi products. It can automatically select and configure the best investment strategy based on factors such APY and safety. In addition, when the yield of each contract fluctuates, the Vaults will automatically adjust positions and transfer funds to help users get the highest financial returns. Users do not need to change any contract, which makes DeFi investment much easier to get started with. ## Profit Distribution The ratio of Performance Fee: 4.5% Performance fee will be deducted from each Vault pool and deposited into [Treasury](https://etherscan.io/address/0x84ee348617563944ffd4a23843e086a7dc0224f3). The profits after deducting the performance fee will be distributed to users in proprotion to their staking. The ratio of Withdrawal Fee: 0.5% In addition, withdrawal fee will be deducted when users withdraw. Among them, 1/4 of the withdrawal fee will be transferred to the [Dev Fund](https://etherscan.io/address/0x0FaEF44d1373F6fdE75926E4564baB5B2d645944#tokentxns), and 3/4 to [Treasury](https://etherscan.io/address/0x84ee348617563944ffd4a23843e086a7dc0224f3). ## Profit Strategy ![](/files/-MOVmPg7nP8wmbFq1rlM) The profit strategy is described as follows: 1. If you choose WETH-DAI UNI-V2 LP Vault and stake the corresponding token, you can obtain svToken as staking voucher. 2. The Vault stakes the UNI-V2 LP Token to the Uniswap pool. 3. UNI rewards will be earned in this pool. 4. The UNI awards earned will be converted to WETH in the Uniswap farm pool. 5. 50% of WETH will be exchanged for DAI. 6. At this time, adding WETH and DAI to the Uniswap DAI-WETH pool can obtain UNI-V2 LP Token. The UNI-V2 LP Token will enter the SashimiSwap Vault as the profits for the user's staking and can be recycled (a 4.5% Performance Fee will be charged when UNI-V2 LP Token enters the Vault). 7. If you need to use svToken to withdraw the staked assets, the corresponding proportion of the capital and profits will be withdrawn at the same time (a 0.5% Withdrawal Fee) . Note: The description above takes the staking of WETH-DAI UNI-V2 LP as an example. ## Fees Comparison | | SashimiSwap Vaults | Yearn | YFII | Harvest | | --------------- | ------------------ | ----- | ---- | ------- | | Withdrawal Fee | 0.5% | 0.5% | - | - | | Performance Fee | 4.5% | 5% | 10% | 30% | ## **Contract Information** Vault Contract: The Vault Contract for each asset: | Pool | Staking Token and Reward Token | Contract Link | | --------------- | ------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------- | | DAI-ETH Vault | DAI-ETH UNI-V2 LP | | | USDC-ETH Vaults | USDC-ETH UNI-V2 LP | | | USDT-ETH Vaults | USDT-ETH UNI-V2 LP | | | WBTC-ETH Vaults | WBTC-ETH UNI-V2 LP | [https://etherscan.io/address/0x81885d776D2963941ec7434F30D61B851E9697F](https://etherscan.io/address/0x81885d776D2963941ec7434F30D61B851E9697FA) | | DAI Vaults | DAI | | | USDT Vaults | USDT | | | USDC Vaults | USD | | ## Tutorial Step 1: Make sure your wallet is connected, and select the Vault on the "Vault" page. ![](/files/-MOVmXrjkgk7UU8MhK_f) Step 2: Take DAI-ETH Vault as an example. First Click the Arrow to expand the page, then enter the amount of the assets to be staked in the input box on the left. The transaction is then confirmed in the connected wallet. If the staking is successful, svToken will be obtained as the staking voucher. You can calculate current earnings based on “1 DAI-ETH svUNI-V2 = 1.000106175477081 DAI-ETH UNI-V2 LP” and APY. ![](/files/-MOVmdLIJkInYX0RHz7z) Step 3: When withdrawing the staked Tokens, enter the amount of svToken in the right input box and click “Withdraw”, then confirm the transaction in the connected wallet to withdraw the staked asset (a 0.5% withdrawal fee will be charged) . # 1.7 Governance ## **Governance Model Introduction** SASHIMI-ETH LP Token (i.e. SASHIMICHAKRA) need to be used for SashimiSwap on-chain governance. Any user can initiate a proposal on , and any user holding SASHIMICHAKRA can vote for or against the proposal. Proposal website: ## **Structure of the First Sashimi Governance Committee** Size of Sashimi Governance Committee: 5 members (might be expanded in the future) The Committee has the following responsibilities: 1\. Initiate a proposal as a member of the core team. 2\. Hold multisig of timelock for future changes. 3\. Give advice on Sashimi's development. Term of Committee members: to be elected every six months Time of establishment: October 20, 2020 ## **Proposal Rules** * The voting period is unlimited, the default period is three days. * Vote by using the SASHIMI-ETH SALP Token (i.e. SASHIMICHAKRA) staked in the Farms, one token, one vote. * The proposal will be passed after the participation rate reaches 30% and the Yes votes exceed 60%. * When the core team initiates a proposal, a proposal number needs to be added before the title, and add ‘1’ based on the latest proposal number. For example, if the latest proposal number is \[SAIP-0001], then the proposal number should be \[SALP-0002] when initiating a new proposal. # 1.8 Sashimi Bar (Staking SASHIMI) ## Introduction ![](/files/-MOVnABBuSmssYebJKc3) Users can stake SASHIMI to obtain SASHIMI from Sashimi Bar.

Users can transfer their asset to the other two chains under the current chain by using the cross-chain trading function of the Sashimi platform to connect to their wallet. The daily available quantity is tentatively set as 200,000 for Huobi Chain and Binance Chain, and 100,000 for Ethereum. If the daily limit exceeded, then users have to wait til 0:00 (GMT) of the next day. In order to ensure that there are enough tokens to support users for both cross-chain transfers and transactions, SashimiSwap development team issued a total of 60,0000 SASHIMI on Huobi Chain and Binance Chain (Binance Smart Chain is 30,0000 SASHIMI, Huobi Chain is 30,0000 SASHIMI), the Ethereum chain transfers 50,000 SASHIMI from the cross-chain pool as the reserve token for the cross-chain smart contract. ## **Cross-chain Trading Tutorial (Example: Huobi Chain)** **Step1: Connect to the wallet (Matemask as an example)** Click the "Connect Wallet" button, the following pop-up window will appear, select "Metamask" to connect to the wallet; ![](/files/-MYy2UJcZx3krtlYGYHA) Step 2: Select your asset There is only "SASHIMI" available and it is selected by default. ![](https://uploader.shimo.im/f/s8L4c7QsckeO96YV.png!thumbnail) **Step 3: Enter the quantity** There is currently no limit to the number of single transactions, but the number of transactions needs to be within the prescribed daily limit transaction amount, and users need to pay a certain additional fee. The service fee is based on the current chain to collect the platform currency under the chain. ![](https://uploader.shimo.im/f/jwq167ZF1IOVGNVa.png!thumbnail) **Step 4: Receiving Address** The receiving address is filled with the default wallet address which can be modified. ![](https://uploader.shimo.im/f/NPqPSGLaR2z72MRZ.png!thumbnail) **Step 5: Confirm the transaction** After clicking “Next”, the information of this transaction will be displayed and the transaction will be confirmed.

Farms use liquidity mining to generate SASHIMI tokens. SASHIMI tokens are 100% generated based on liquidity mining, without any pre-sale, pre-mining and team distribution. SASHIMI holders can participate in platform governance and obtain dividends from the platform. The platform income now includes transaction fees, income from liquidity investment, and Vault fee income. Below is the SASHIMI release plan: The total supply of SASHIMI is 100M, and the distribution will be reduced according to the rules shown in the figure below until the total distribution reaches 100M. ![](/files/-MOVnxGYfFnOYmjvpuZs) ## SALP Token SALP Token is a voucher for adding liquidity on the Exchange; each liquidity pool has its unique SALP Token, and withdrawal of liquidity will burn SALP Token. Currently, SALP Token can be staked in Farms for liquidity mining. ## **svToken** svToken is the voucher for staked assets in Vaults; each transaction pool has its unique svToken, which will be burnt after staked assets are withdrawn. svToken will continue to appreciate based on the income in Vaults; the higher the income, the higher the value of svToken, the more staked assets will be withdrawn. svToken supports staking in Farms for liquidity mining. ## **xSASHIMI** xSASHIMI is the voucher for staking SASHIMI in Sashimi Bar, and withdrawal of staked SASHIMI will burn xSASHIMI. xSASHIMI will continue to appreciate based on the income in Sashimi Bar; the higher the income, the higher the value of xSASHIMI, the more SASHIMI will be withdrawn. ## **xLP Token** xLP Token is the voucher for staking LP Token in LP Token Bar in Double Farming. xLP Token will be automatically staked in Farms for liquidity mining and will not enter the user’s wallet. # 3.Configure RPC network on Metamask ## Configure RPC network on Metamask ### **1.Huobi Eco Chain (HECO)** Step 1: Click "Ethereum Mainnet" on the top. ![](https://uploader.shimo.im/f/wRYhGOm0kVl66Z5t.png!thumbnail) Step 2: Select "Custom RPC" . ![](https://uploader.shimo.im/f/5FSZpnX5hHJdFkY3.png!thumbnail) Step 3: Custom RPC network setting: * Network name ``` HECO mainnet // you can set a name you like ``` * New RPC URL ``` https://http-mainnet.hecochain.com ``` * Chain ID ``` 128 ``` * Symbol (optional) ``` HT ``` * Block explorer URL (optional) ``` https://scan.hecochain.com ``` Here is an example： ![](https://uploader.shimo.im/f/w8ANWkGr1vFsSmSt.png!thumbnail) Then click "Save".

Whereas most other platforms primarily rely on transaction fees, SashimiSwap also has significant investment returns by optimally and automatically investing a part of the idle liquidity in the most profitable platform(s), automatically adjusted every day. If likened to a foreign exchange, then SashimiSwap is depositing part of its assets into the bank to earn interest. **Q: Where can I buy** **SASHIMI？** A： Currently, you can get SASHIMI on SashimiSwap Exhcange and Uniswap. The link is: * SashimiSwap Exchange： * Uniswap： **Q: Will** **SashiSwap's assets** **be used for the aelf community or the** **Sashimi community?** A: Unlike SushiSwap, which distributes 10% of its funding each time to the founding team for development, future iterations, audits, etc. SashimiSwap did away with such “development funds”. SASHIMI tokens are 100% distributed based on liquidity mining, without any pre-sale, pre-mining and team distribution. **Q: What is timelock?** A: Timelock means when you send a transaction, the contract is executed after a set period, say, we set the period at 2 days, like Sushi. Timelock cannot lock liquidity, It is to prevent anyone from stealing tokens. **Q: Has** **the Sashimi contract been audited?** A: Audit Report * Here is a comparison of the Sashimi and Sushi Masterchef contracts, as well as the SASHIMI and SUSHI Tokens: * Here’s a comparison of the Timelock contracts: **Q:How to make a proposal that attracts more voting?** A:1. Add new proposal * Open the Sashimi snapshot site: * Click “**New proposal**” on the project homepage. * Fill in the Title in accordance with the project naming standard. * Fill in the large text field with your community proposal. * Select the desired voting options. * Now go to the “**Actions**” box. * Select the start date. * Select the end date (allow enough time for voting). * Enter the snapshot block height (See below: **Add a snapshot block** **height**). * Click “**Publish**” to create proposal. * Sign the message via your wallet and it's done. 2\. Add a snapshot block height The block height is important as it will lock the state of community members who are able to vote. This means that if you attempt to vote on a proposal, but the block height is in the past and you weren't holding the required token yet, your vote will not count. 3\. Voting * Open the Sashimi snapshot site: * Go to your project's snapshot page * Click the option you want to vote for * Sign the message via your wallet Note: When you vote on the SASHIMI snapshot platform , you need to use the ETH-SASHIMI SALP staked in the Farms, namely SASHIMICHAKRA. One token = one vote, otherwise the vote is invalid. Check the detailed tutorial on voting on snapshot: **Q:How does Staking work? Why** **am** **I not seeing my investment go up?** A:SashimiSwap offers staking to incentivize users who hold and stake tokens. Users can stake their tokens at any time without time locks. When staking SASHIMI tokens, the tokens are converted into xSASHIMI as redemption voucher. The amount of xSASHIMI at the time of initial conversion will be the same as the amount of the staked SASHIMI tokens. xSASHIMI will appreciate as the returns in Sashimi Bar increase; the higher the returns, the more valuable the xSASHIMI, the more SASHIMI tokens users can withdraw. Over time, SASHIMI tokens are bought back from the platform via multiple means, such as income from Investment and Exchange. Bought back tokens are made available to the stakers on the SashimiSwap platform. Over time, the amount of available bought back SASHIMI will increase. However, the amount of xSASHIMI will stay the same in a user's account; this makes xSASHIMI worth more over time. When the user decides to withdraw his/her tokens from staking, the available xSASHIMI will yield more SASHIMI tokens than initially staked. Important note: during the staking process, it will seem like no tokens are earned, as the xSASHIMI amount in the wallet does not change. However, if you look at the current xSASHIMI:Sashimi swap ratio on the staking page (), you will find this ratio goes up over time as the returns in Sashimi Bar increase, making your investment worth more over time. Example: a user has staked 1000 SASHIMI tokens and received 1000 xSASHIMI tokens back. At the time of convertion 1 xSASHIMI was worth 1 SASHIMI. After a week of staking, xSASHIMI now worth 1.028 SASHIMI. The user is happy with the yield and decides to stop staking. By converting xSASHIMI back to SASHIMI, he now receives 1028 SASHIMI tokens in return. ## FAQ about Sashimi Lending #### Q: How much interest can I earn from my deposits? A: The income earned by slToken holders includes two parts: * Interest income: depositors will get interest income according to the dynamic annualised interest rate of deposits. Each type of asset has its own supply and demand market, and the corresponding APY(annual average rate of return) changes dynamically with the relationship between supply and demand. * $SASHIMI incentive: the platform will provide $SASHIMI incentive for users participating in Sashimi Lending. The specific reward amount is related to markets and asset amount in the market. #### Q: Is there a minimum or maximum deposit amount? A: You can deposit any amount without minimum or maximum limit. However, it is important to know that for very low amounts, the transaction costs of the process may be higher than the expected benefits. We recommend you to consider this when you deposit a very low amount. #### Q: Why should I borrow rather than sell assets? A: Selling your asset means closing your position on that particular asset. Therefore, you lose the upside potential. By borrowing against the asset, you can monetise without selling it. Users borrow mainly for unexpected expenses, using their holdings or seeking new investment opportunities. #### Q: How much can I borrow? A: The maximum amount you can borrow depends on the value of the assets you deposited and the liquidity available. For example, if there is insufficient liquidity or your Loan to Value rate does not allow you to borrow more, you cannot do so. You can check out the specific Loan to Value rate of each market on webpage. #### Q: What assets do I need to repay? A: You repay the loan with the same asset you borrow. If you borrow 1 ETH, you will pay off 1 ETH plus accrued interest. If you want to repay according to the US dollar price, you can borrow any available stablecoin, such as USDC, DAI, USDT, etc. #### Q: How much interest do I have to pay? A: The interest rate you pay for the borrowed asset depends on the borrowing rate derived from the asset's supply-demand relationship. We use floating interest rates, which vary with supply and demand. You can find the current borrowing rate at any time in the "APY" of the Borrow Market. #### Q: What is the Loan to Value ratio? A: The Loan to Value ratio is the ratio of the maximum amount you can borrow to the dollar value of your collateral. The lower the value, the healthier your account is. If the Loan to Value ratio reaches 100%, liquidation will be triggered. #### Q: What happens when my Loan to Value ratio goes up? A: When the value of your collateral fluctuates, the Loan to Value ratio will change dynamically. If your Loan to Value ratio is low, the liquidation is less likely to be triggered, thus improving your account healthy level. If the value of the collateral decreases relative to borrowed assets, the Loan to Value ratio will increase, resulting in higher liquidation risk. #### Q: When do I need to pay back the loan? A: There is no tenor of the loan. As long as your position is safe, you can borrow money. However, accrued interest will increase over time, which will increase your Loan to Value ratio, as well as the liquidation risk. #### Q: How to avoid liquidation? A: To avoid liquidation, you can improve the health level of your account by top up collateral or repay part of the loan. Repayments are more effective than increasing collaterals. It is important to monitor your Loan to Value ratio and keep it at a reasonable level to avoid liquidation. For example, keeping the Loan to Value ratio below 50% will definitely keep you safe. # SashimiSwap 官网： Ethereum V1： Ethereum V2: [https://v2.sashimi.cool/](< https://v2.sashimi.cool/>)​ 币安链BSC： 火币链Heco： （移动端可以通过imToken钱包使用该产品） Discord：[http://discord.com/invite/mSEc2uv](https://t.co/5lmtO4NkYO?amp=1)​ Telegram：[http://t.me/SashimiSwap](https://t.co/xYoRvxLZ1u?amp=1)​ Twitter：​ Medium：​ 官方代码：​ 审计报告：​ APY API：​[

**Exchange介绍** SashimiSwap Exchange是SashimiSwap的去中心化交易平台，采用了以Uniswap为代表的去中心化交易所中广泛流行的AMM自动做市商（Automated Market Maker）机制进行交易。 其原理是使用CFMM（Constant Product Market Maker）恒定乘积做市商模型建立交易市场，通过定积函数 x∗y=k，根据每个Token的可用数量（流动性）来确定两种Token的价格范围。由于一个交易池中两种Token的相对价格通过交易改变（遵循定积函数规则），因此交易池的Token价格与外部价格之间的差异会产生套利机会。这种机制确保Token价格始终趋向于市场结算价格。 在SashimiSwap Exchange中，提供以下两种功能： （1）Add / Remove Liquidity： 用户向交易池注入交易对中价值相等的两种Token并获得相应的LP Token，LP Token代表用户在该交易池中添加的资产的赎回凭证，允许用户随时赎回其资产。 （2）Swap： 允许用户通过交易池将任何ERC20 Token兑换为另一种ERC20 Token，同时，用户需要支付0.3％的交易手续费。 ##

]()Sashimi Lending利率模型 ### 1.存款金额利息的产生 存款人存入标的资产后可以获得一定数量的slToken，slToken可以用于兑换回标的资产。slToken对标的资产的兑换率，在存入资产后会随时间增加，兑换率增加的部分即为存款人获得的利息。 平台借款量越多，兑换率增加越快。 ### 2.slToken兑换率 slToken兑换率（ExchangeRate）依照以下数据做计算（以Lending USDT为例）： * totalCash=已放入智能合约，但还没有被借走标的资产总数量 * totalBorrows=所有借款人所应偿还贷款的总数量（含应计利息） * totalReserves=准备金总数量（借款人所应支付的利息，部分被视为准备金） * totalSupply=所有存款人所得到slToken的总数量 *ExchangeRate* *=（totalCash+totalBorrows-totalReserves）/ totalSupply* ### 3.资金利用率 资金利用率（UtilizationRate）表示所有供给资产中，被借走的资产所占比例： *UtilizationRate* *=totalBorrows /（totalCash+totalBorrows）* ### 4.借款年利率 在Sashimi Lending利率模型里会计算借款年利率（BorrowRate），即借款人在当下所需支付利息的年利率，这个利率会受到以下因素影响： 1.基础利率（BaseRate） 2.资金利用率（UtilizationRate） 3.乘数（Multiplier） *BorrowRate = UtilizationRate \* Multiplier + BaseRate* ### 5.存款年利率 存款年利率（SupplyRate）为存款人会收到的年化利息率，存款年利率会受到以下因素影响： 1.借款年利率（BorrowRate） 2.资金利用率（UtilizationRate） 3.准备金系数（ReserveFactor） *SupplyRate≈* *BorrowRate* *\** *UtilizationRate* *\*（1* *-* *ReserveFactor）* 在Sashimi Lending利率模型里面，每个币种的**基础利率、乘数、准备金系数**可能不尽相同，但都是智能合约里的常数，会在合约代码中公开。 智能合约里有可以让管理者修改这些常数的权限，因此Sashimi Lending社区可以视情况做调整，而任何调整都能在区块链上公开透明得查询到。 ## 清算规则 抵押资产价格会发生波动，当借款人抵押资产因价格波动而不足以支付未偿还借款时，将会触发账户清算：抵押资产将会被清算人以约定的折扣价格卖出以偿还借款。价格折扣为清算人完成清算所获的激励。 在Sashimi Lending清算模型里面，清算激励是智能合约里的常数。 ## Sashimi Lending教程 ### Sashimi Lending模块 #### 1.用户资产模块 * “Supply Balance”表示用户的存款金额和已赚利息的总和； * “Borrow Balance”表示用户的借款金额和应付利息的总和； * “Net APY”表示净年利率； * “Borrow Limit”表示借款限额，用于表示用户账户的健康水平。当Borrow Limit较低时，账户是安全的。如果达到可借资产限额的100%，将触发清算。 ![](/files/-MOfUJjNMRs7DWR4l_Vs) #### 2.借贷市场模块 在“Supply”和“Borrow”资产列表分别展示不同币种的供应市场（Supply Market）和借币市场（Borrow Market），用户可以向供应市场存款，也可以从借贷市场借款。 ![](/files/-MOfUaMpDIxA7VNP5-C8) ### 操作流程 #### 1.连接钱包 打开借贷页面，点击页面右上角“Connect Wallet”按钮，在弹出的连接钱包弹窗中选择对应的钱包（以Metamask为例），按要求连接钱包；连接成功后点击页面右上角按钮即可查看钱包信息。 ![](/files/-MOZceb2YHZKQYarUhhE) ![](/files/-MOZd1ZCZpLUPk6QvhUT) #### 2.存入资产 选择将要存款的币种，以SASHIMI为例，点击SASHIMI，在存款弹窗中输入存款数额，点击“SUPPLY”按钮，并在连接的钱包中确认该交易。 注意：智能合约需要通过授权弹窗进行授权；存款成功后，将根据 Supply APY随时间累计生息。 ![](/files/-MOZNG-DEVq8KikYxapH) ![](/files/-MOZNNLx85EH5Ld1g-XU) #### 3.抵押资产 用户可以通过资产列表的开关器来启用或禁用资产的抵押，抵押后可借款额度（Borrow Limit）将相应变化（借款额度 = 存入Token价值 \* 抵押率）。 用户只有抵押资产后才能进行借款，抵押资产可以保证用户有足够的资产偿还借款，如果借款金额超过借款额度将触发清算机制。 以选择SASHIMI为例，点击SASHIMI币种“Collateral”列的开关按钮，在弹出的弹窗中点击“Enable SASHIMI as Collateral”按钮进行授权，并在连接的钱包中确认该交易。 交易完成后，将打开SASHIMI抵押开关；如果有SASHIMI存款，则“Borrow Limit”的百分比将相应增加。 ![](/files/-MOZdDUe8g-kdVRYflym) ![](/files/-MOZNw6FFJjU1yRSttMa) 以SASHIMI为例，取消抵押资产时，将考虑两种情况： 情况1：未借出资产、或已借出资产但是取消抵押不足以触发清算机制时，点击“Collateral”列的开关按钮，在以下关闭授权弹窗中点击“DISABLE SASHIMI”即可关闭。 关闭成功后，开关器将关闭，如果有SASHIMI存款，则“Borrow Limit”将对应减少。 ![](/files/-MOZOKdorlxLZ3HPSznZ) 情况2：如果取消抵押会触发清算机制时，无法关闭开关器。 ![](/files/-MOZSrAKmdbndMERIKAv) #### 4.借入资产 以SASHIMI为例，点击SASHIMI，在借款弹窗中输入存款数额，点击“BORROW”按钮，并在连接的钱包中确认该交易以完成借款。 借款成功后，后续将根据Borrow APY随时间累计生息。 注意：必须先存入资产作为抵押才能借入资产，否则无法借入资产。 ![](/files/-MOZOT0TaABhnRwMLfLx) ![](/files/-MOZObaay0CjVcP0poBf) #### 5.提取资产 以提取全部或部分SASHIMI为例，用户可点击SASHIMI，在存款弹窗中选择“WITHDRAW”标签，输入提款数额，点击“WITHDRAW”按钮并在连接的钱包中确认该交易。 注意：支持随时提款，提款时可提取本金和已赚利息。提款金额最大值 = 存款金额 -

A:与SushiSwap不同，SushiSwap将10％的SUSHI资金分配给创始团队，用于产品开发、更新和审计等；SashimiSwap取消了这种“开发资金”，SashimiSwap的平台币100%通过流动性挖矿分发，无任何的预售、预挖及团队分配。
**Q:什么是timelock合约?** A:时间锁合约是指发送交易后，合约将在指定段时间之后执行，当前Sashimi设置的时间段为24小时。时间锁不能锁定流动性，它是防止任何人窃取代币等作恶行为的一种保障。
**Q:SashimiSwap是否通过审计？** A:SashimiSwap合约审计报告： 这是Sashimi和Sushi的合约对比： * MasterChef合约： * Timelock合约对比： **Q:如何发起提案和投票?** **A:（1）发起提案：** 1. 打开Sashimi snapshot平台（） 2. 单击提案页面右上角上的“New proposal”按钮。 3. 根据提案命名标准填写标题； 4. 添加提案内容； 5. 设置所需的投票选项； 6. 现在转到“Action”区域； 7. 选择开始日期； 8. 选择结束日期（留出足够的时间进行投票）； 9. 填写Snapshot block number（请参见下文：添加snapshot block number）； 10. 点击“Publish”创建提案； 11. 通过钱包确认交易。 添加snapshot block number： 默认显示的快照高度为当前以太坊区块高度，表示将在当前高度获取已质押的LP Token数据快照，只有当前的记录的已质押的LP Token才可以参与投票，在该区块高度之后再质押的LP token将不能用于投票，票数也不被计入。 **（2）投票：** 1. 打开Sashimi snapshot平台（）； 2. 选择提案，并进入详情页； 3. 选择想要投票的选项； 4. 通过钱包确认交易。 注：在Sashimi snapshot平台（）上进行投票时，需使用在Farms中质押的ETH-SASHIMI SALP，即SASHIMICHAKRA才能进行投票，一币一票，否则投票无效。 具体的操作教程可查看Snapshot官方文档： **Q:如何质押SASHIMI? 为什么在质押过程没有任何收益?** A:*# From FlorisJan* SashimiSwap提供了一些权益来激励持有和质押SASHIMI的用户。用户可以在任意时间质押SASHIMI；质押SASHIMI时，将获得xSASHIMI作为赎回凭证。 质押时生成的xSASHIMI价值与质押的SASHIMI价值相同。xSASHIMI将根据Sashimi Bar中的收益的增加而不断升值；收益越高，xSASHIMI价值越高，则用户提取的SASHIMI将会越多。 SashimiBar的收益会通过多种方式从平台购回，例如Investment理财收益、Exchange等。 注意：在质押过程中，似乎不会获得任何收益，钱包中的xSASHIMI数量不会改变。但是在操作页面（）上可以查看当前的xSASHIMI：SASHIMI交换比率。该比率会随着Sashimi Bar收益的增加而变化，从而使拥有的xSASHIMI价值变得越来越高，xSASHIMI的升值意味着获取了额外的SASHIMI收益。 示例： 用户质押了1000 SASHIMI并收到了1000 xSASHIMI，当前1 xSASHIMI = 1 SASHIMI。 一周时间后，1 xSASHIMI = 1.028 SASHIMI；用户当前使用xSASHIMI提取质押的SASHIMI时，可以获得1028 SASHIMI，则该用户的收益为28 SASHIMI。 ## Sashimi Lending常见问题 **Q:我存款会赚多少钱？** A:slToken持有者获得的收益包括两部分： * 利息收益：存款人会获得按照浮动存款年利率计算的利息收益，每类资产都有其自己的供需市场，相应的APY（年平均收益率）随供需关系动态变化； * $Sahimi奖励：平台会为参与SashimiLending的用户提供$Sashimi激励，具体的奖励额度与参与的市场类别和存款额有关。 **Q:是否有最低或最高存款额？** A:您可以存入任何您想要的金额，没有最低或最高限额。不过，重要的是要考虑到，对于非常低的金额，流程的交易成本可能会高于预期收益。我们建议您在存入非常低的金额时考虑这一点。 **Q:为什么我要借而不卖资产？** A:出售您的资产意味着关闭您在该特定资产上的头寸。因此，如果您长期持有资产，则无权获得潜在的上行价值收益。通过借款，您无需出售资产就能获得流动性（流动资金）。用户借贷主要是出于意外支出，利用其持有量或寻求新的投资机会。 **Q:我可以借多少钱？** A:您可以借出的最大金额取决于您存入的资产价值和可用的流动性。例如，如果流动性不足或您的抵押率不允许您借出资产，则无法借入资产。您可以在每个市场的页面查看具体抵押率参数。 **Q:我需要偿还什么资产？** A:您用借出的同一资产偿还贷款，如果您借出1 ETH，您将还清1 ETH +应计利息。如果您想根据美元价格还款，可以借用任何可用的稳定币，例如USDC，DAI，USDT等。 **Q:我要付多少利息？** A:您为借款资产支付的利率取决于从资产的供求比率得出的借款利率。我们使用的是浮动利率，随供求关系不断变化。您可以随时在市场页面的“借款利率”部分中找到当前借款利率。 **Q:什么是抵押率？** A:抵押率是您能借到的最高金额与抵押资产价值的比率。该值越低，您的资金状态在进行清算时就越安全。如果抵押率达到100%，则会触发您的借款清算。 **Q:当我的抵押率升高时会发生什么？** A:根据您的抵押资产价值波动，抵押率会增加或减少。如果您的抵押率降低，将使清算门槛更不可能达到，从而提高你的账户健康水平。如果抵押资产的价值相对于借出资产的价值下降，则抵押率会升高，从而导致清算风险增加。 **Q:我什么时候需要还贷？** A:没有固定的时间偿还贷款。只要您的头寸安全，就可以无期限借款。但是，随着时间的流逝，应计利息将增加，从而使您的抵押率升高，这可能导致您存入的资产变得更可能被清算。 **Q:如何避免清算？** A:为了避免清算，您可以通过增加更多抵押资产或偿还部分贷款等措施来提高账户的健康水平。默认情况下，还款比增加抵押资产更加有效。同样重要的是，监视您的抵押率并使其保持合理水平，以避免被清算。例如，将抵押率保持在50%以下，可以为您带来更大的空间，避免清算。 **Q:为什么有时候不能收集已赚取的Sashimi ？** A：Lending用户赚取的Sashimi是从Farm中定期转到合约地址的，有时候不能收集已赚取的Sashimi是因为合约地址中 Sashimi的数量暂时不够，等待几天后就可以提取。
