Cozy Token Buyer Contracts

This repository includes custom Cozy V2 price feeds and deploy scripts for nounsDAO/token-buyer.

Contracts

CozyMultiOraclePriceFeed
- Returns a price for ETH/PToken using two external oracles (e.g. Chainlink). A PToken is an ERC20 that represents protection purchased from a specific Cozy market (e.g. stETH Peg Protection).
- This price feed is useful for chains where there does not exist an oracle for the specific ETH/underlying asset of the PToken (e.g. ETH/PToken using ETH/USD and USDC/USD for PToken with USDC underlying).
- Uses a set bidPriceWAD which equals the percentage price per unit of protection (e.g. 0.02e18 for 2%). The owner of the CozyMultiOraclePriceFeed can update bidPriceWAD.

Since we're running some tests with an Optimism fork, add your Optimism RPC url to your environment variables:

export OPTIMISM_RPC_URL=<yourOptimismRpcUrl>

Then run the tests:

forge test

This repo includes Forge scripts under script/ for:

Specific instructions on how to run them is embedded into the comments of each script.

See the DeployL2USDCPTokenTokenBuyer script for deploying token-buyer using the CozyMultiOraclePriceFeed for a PToken with USDC underlying.
