This contract will allow users to deposit allowed tokens or native chain asset (Mainnet ETH) backed by API3 oracles. A very simplified version to understand the flow of how borrow / lending works
Primary Functions:
- setTokensAvailable: Add Token addresses and Price feeds of toksns your contract supports.
- setNativeTokenProxyAddress: Manually set PriceFeed of Native Chain Assest (does not contain a token address).
- depositToken: Use allowed tokens for collateral.
- depositNative: Deposit chain native asset without having to wrap it.
- borrow: Borrow up to 70% of deposited value (based on oracle value).
- repay: Payback your debt.
- withdraw: Take back deposits based on deposit and borrow balances.
- liquidate: Pay back the debt of another user with a reward of deposited
Tokensif health factor goes below 1. - liquidateForNative: Pay back the debt of another user with a reward of deposited
Native Assetif health factor goes below 1.
$ forge buildIn the testing portion, 3 different oracles on Mocked each with their own contract. On the local deployment one is set to a stable coin such as USDC, another is a Native Asset (ETH), and the other is the Wrapped Version of the Asset (WETH).
Test scenarios for deposit, borrow, repay, withdraw and liquidate
