# fSUSHI fSUSHI is a protocol built on top of [FlashStake](http://flashstake.io/) and [SushiSwap](https://sushi.com) that enables stakers to get instant, upfront yield without waiting for it to accrue. ## Deployments ### Mainnet | Contract | Address | | ----------------------------- | --------------------------------------------------------------------------------------------------------------------- | | FSushi | [0xA24390c62186A8D265344e914F0Fd962B81b5F13](https://etherscan.io/address/0xA24390c62186A8D265344e914F0Fd962B81b5F13) | | FSushiAirdrops | [0x4909B5a6Fbd15884fed4F5D1Af829AF5e9bc8e28](https://etherscan.io/address/0x4909B5a6Fbd15884fed4F5D1Af829AF5e9bc8e28) | | FSushiAirdropsVotingEscrow | [0x7C375121690Bd65295B33c526F39dA1BAEDcFC97](https://etherscan.io/address/0x7C375121690Bd65295B33c526F39dA1BAEDcFC97) | | SushiBarVault | [0x3e55AC0E6724BBe8aB40a60771B5D60fC8e93404](https://etherscan.io/address/0x3e55AC0E6724BBe8aB40a60771B5D60fC8e93404) | | FarmingLPTokenFactory | [0xEE083E0F0f5dE2ff34662F1ef6f76d897d5047EF](https://etherscan.io/address/0xEE083E0F0f5dE2ff34662F1ef6f76d897d5047EF) | | FlashStrategySushiSwapFactory | [0x77b8E6e577fd3e90553dbF205D3854a649414741](https://etherscan.io/address/0x77b8E6e577fd3e90553dbF205D3854a649414741) | | FSushiBar | [0x8f77a1f6D36c6F3005B33E4071733C7057463Ca5](https://etherscan.io/address/0x8f77a1f6D36c6F3005B33E4071733C7057463Ca5) | | FSushiKitchen | [0xe4CC24Fa7bbcCD83cF10a20760B1b842Cb750421](https://etherscan.io/address/0xe4CC24Fa7bbcCD83cF10a20760B1b842Cb750421) | | SousChef | [0x991660133a987F21c6225027C33B9B5680272850](https://etherscan.io/address/0x991660133a987F21c6225027C33B9B5680272850) | ## How it works ``` ┌───────────────────┐ │ │ │ SousChef │ │ │ └───────────────┬───┘ ▲ │ fToken │ │ fSUSHI │ ▼ ╔══════╧════════════╗ fLP Token ┌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌┐ ┌───────────────────┐ ║ ╟────────────►┤ │ fLP Token │ │ ║ User ║ │ FlashProtocol ├────────────►│ FlashStrategy │ ║ ║◄────────────┤ │ │ SushiSwap │ ╚══════════════╤════╝ fToken └╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌┘ └───────────────────┘ ▲ │ fLP Token│ │ SLP Token │ ▼ ┌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌┐ invest SUSHI ┌───────────────────┐ SUSHI yield ┌─────┴─────────────┐ │ AAVE SUSHI pool │◄──────────────┤ │◄──────────────┤ │ │ or │ │ SushiBarVault │ │ FarmingLPToken │ │ xSUSHI etc. ├──────────────►│ ├──────────────►│ │ └╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌┘ accrued SUSHI └───────────────────┘ accrued SUSHI └──────────────┬────┘ ▲ │ SUSHI yield │ │ SLP Token │ ▼ ┌╌╌╌╌╌┴╌╌╌╌╌╌╌╌╌╌╌╌╌┐ │ │ │ MasterChef │ │ │ └╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌┘ ``` ## Contracts ### FarmingLPToken You can deposit SushiSwap LP tokens and get the equivalent amount of `fLP` tokens. The difference from the original LP tokens is that the _SUSHI_ yield is automatically accrued to your `fLP` balance. Also, pending _SUSHI_ yield is being optimized by the dynamic strategies to get higher profits. ### FlashStrategySushiSwap A FlashStake strategy to enable `FarmingLPToken`s to be used as principal and stakers get instant, upfront _SUSHI_ yield. You can also stake without instant yield and in this case you get `fToken`s that are minted from FlashStake protocol. ### SousChef By depositing your `fToken` you're eligible for receiving newly minted `fSUSHI` rewards. In the first week, 300,000 `fSUSHI`s will be distributed and in 2nd week, only 1/10 of the circulating supply of the first week will be minted. (10x boost in the first week) And during the 2nd week, only 99% of the first week's circulating supply will be minted. During the 3rd week, only 99% of the second week's circulating supply will be minted. This goes on and on. Thus, you can reduce inflation rate of your `fSUSHI` by locking up your assets to `FSushiBar`. ### FSushi - _fSUSHI_ A plain ERC20 token that only `SousChef` can mint. ### FSushiBar - _xfSUSHI_ 1% fee is posed as fee for upfront yield and 0.25% for plain staking. These fees will be distributed for `xfSUSHI` holders who locked up their `fSUSHI`. General mechanism isn't much different from `SushiBar` of SushiSwap protocol. ## License Distributed under the BUSL-1.1 License.
