- Support collateral liquidation through curve and uniswap without any capital
- Collateral liquidation profits in settlement token (USDC)
- Access Control
- Contract owner can withdraw fund (USDC) from the contract and do liquidation
- Whitelisted EOA can liquidate through the contract to liquidate more efficiently
You should have Node v16 installed. Use nvm to install it.
npm i
npm run build
Prerequisite:
- duplicate
.env.build.example - rename it to
.env.build - fill all of the fields
- change contract owner or whitelisted EOA if needed from
deploy/001-deploy-liquidator.ts
ℹ️ Note for .env parameters
MAX_SETTLEMENT_TOKEN_SPENTis denominated in USDC. If your liquidation claim exceeds the amount available (e.g. due to another liquidator claiming part or all of the collateral faster than you), your transaction will fail. Setting a lower limit lets you claim a smaller amount and may increase your chances of success.
To deploy the contract:
# to Optimism Goerli (testnet)
npm run deploy-contract-optimism-goerli
# to Optimism (mainnet)
npm run deploy-contract-optimismPrerequisite:
- duplicate
.env.runtime.example - rename it to
.env.runtime.optimism(or.env.runtime.optimism-goerlifor testnet) - fill all of the fields
- setup the swap path at
src/metadata.tsto deal with the non-USD collateral (to flash loan/swap from a specific pool)
