I'm looking for V1 contracts but written in solidity. i did found this one: https://github.com/PhABC/uniswap-solidity/blob/master/contracts/uniswap/UniswapExchange.sol
But i prefer a tested codes, this looks like a rewrite/converted codes. don't want to be worry about auditing.
So anyone knows a DEX using v1 contracts or a project using v1 swap codes? would really appreciate it.
