/EIP-712-swap-PoC

Primary LanguageSolidity

EIP-712 swap PoC

Uses strongly-typed signed messages to send "Uniswap orders" to a block builder (e.g. Flashbots).

i think this is how it works

Helpful stuff

  • contracts/ and backend/ require that you cp .env.example .env and modify the contents to suit your needs

  • yarn start will run backend and frontend.

  • cd contracts/ && yarn deploy-goerli

TODO

  • verify signed message
  • upgrade signed message type to V4
  • write smart contract (validator/executor) to decode tx and verify signature
  • send to uniswap from (validator/executor)
    • implement v2 functions, use SwapRouter (v2 + v3) if possible
  • send (validator/executor) tx to flashbots (not important for PoC)
