R provides the most capital-efficient way to borrow using your stETH. R aims to be the stablecoin of choice within the decentralized ecosystem, with deep liquidity across many trading pairs and a stable peg.\n\nThis repository contains the Raft smart contracts written in Solidity. To learn more about Raft, please visit [our website](https://raft.fi) and [docs](https://docs.raft.fi).\n\n## Getting Started\n\n### Prerequisites\n\nTo build and test the Raft smart contracts, you will need the following:\n\n- [Solidity](https://docs.soliditylang.org/en/v0.8.19/installing-solidity.html)\n- [Foundry](https://github.com/foundry-rs/foundry)\n- [Node.js](https://nodejs.org/en/)\n- [Yarn](https://yarnpkg.com/)\n- [Slither](https://github.com/crytic/slither)\n\n### Installation\n\nClone the repository with its submodules, set up\n[Foundry](https://book.getfoundry.sh/getting-started/installation), and install the dependencies via Yarn:\n\n```bash\nyarn install\n```\n\n### Testing\n\nTo run the tests, run the following command:\n\n```bash\nforge test\n```\n\n### Static Analysis\n\nTo run the Slither static analysis tool, run the following command:\n\n```bash\nslither .\n```\n\n## Contracts\n\n### Core Contracts\n\n| **Contract** | **Description** |\n| -------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| [`PositionManager`](contracts/PositionManager.sol) | The entry point for managing [positions](https://docs.raft.fi/how-it-works/position). It also handles the logic for [borrowing](https://docs.raft.fi/how-it-works/borrowing) R tokens and [repayment](https://docs.raft.fi/how-it-works/returning/repayment) of the debt, as well as [liquidations](https://docs.raft.fi/how-it-works/returning/liquidation) and [redemptions](https://docs.raft.fi/how-it-works/returning/redemption). |\n| [`RToken`](contracts/RToken.sol) | An ERC-20 token designed to [retain a value of 1 USD](https://docs.raft.fi/about-r). R can be minted and burnt only by `PositionManager`. |\n| [`ERC20Indexable`](contracts/ERC20Indexable.sol) | Rebase token which is used as the debt token implementation. |\n| [`SplitLiquidationCollateral`](contracts/SplitLiquidationCollateral.sol) | Used by `PositionManager` to calculate how liquidated collateral should be split between the liquidator and the protocol. |\n| [`PriceFeed`](contracts/PriceFeed.sol) | Retrieves asset prices from a primary oracle, using a secondary oracle as a fallback when the primary is unavailable or compromised |\n| [`ChainlinkPriceOracleWstETH`](contracts/Oracles/ChainlinkPriceOracleWstETH.sol) | Chainlink oracle integration contract. |\n| [`TellorPriceOracleWstETH`](contracts/Oracles/TellorPriceOracleWstETH.sol) | Tellor oracle integration contract. |\n\n### Periphery Contracts\n\n| **Contract** | **Description** |\n| ------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |\n| [`PositionManagerStETH`](contracts/PositionManagerStETH.sol) | Allows managing positions with ETH or stETH collateral. Responsible for wrapping/unwrapping ETH and stETH into/from wstETH. It has to be whitelisted by a user in `PositionManager`. |\n| [`OneStepLeverage`](contracts/OneStepLeverage.sol) | Facilitates opening, closing, or adjusting leverage on wstETH positions with a single transaction, employing flash mint to streamline the process and reduce transaction complexity. |\n| [`OneStepLeverageStETH`](contracts/OneStepLeverageStETH.sol) | Extends the functionality of `OneStepLeverage` to allow using ETH and stETH. |\n| [`FlashMintLiquidator`](contracts/FlashMintLiquidator.sol) | Facilitates the liquidation of undercollateralized positions in a single transaction, employing flash loans to streamline the process. |\n| [`ParaSwapAMM`](contracts/AMMs/ParaSwapAMM.sol) | ParaSwap integration contract. Can be used by `OneStepLeverage`, `OneStepLeverageStETH` and `FlashMintLiquidator`. |\n| [`BalancerAMM`](contracts/AMMs/BalancerAMM.sol) | Balancer integration contract. Can be used by `OneStepLeverage`, `OneStepLeverageStETH` and `FlashMintLiquidator`. |\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fraft-fi%2Fcontracts","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fraft-fi%2Fcontracts","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fraft-fi%2Fcontracts/lists"}
