P2PTrade

Peer to peer swap middleman for ERC20, ERC721 and ERC1155 assets

Usage

Usage and implementation is at users own risk, no tests have been done or security has been audited

Prerequisites

  • All assets much have their respective allowances made for the P2PTrade contact to transfer them
  • walletB must have provided a signature of the trade

Executing a swap

  • fromA: Assets msg.sender will send to walletB
  • fromB: Assets walletB will send to msg.sender
  • deadline: UNIX timestamp that the trade must be executed before (seconds)
  • walletB: Party trading with the msg.sender
  • aNonce: Trade nonce of msg.sender, must be the next integer after the last used nonce for address
  • bNonce: Trade nonce of walletB, must be the next integer after the last used nonce for address
  • v, r, s: Signature of the hashed swap parameters signed by walletB
  P2PTrade.swap(Items[] calldata fromA, Items[] calldata fromB, uint256 deadline, address walletB, uint256 aNonce, uint256 bNonce, uint8 v, bytes32 r, bytes32 s)

TODO

  • Implement EIP712 signature verification (EIP712 Domain Seperator is implemented but not utilized)
  • Add Tests
  • Create deploy script
  • Create example interaction with ethers
