Trustless OTC Trade

The Trustless OTC smart contract is deployed at (0x62f49e904af170Ea377F399aCa76C13fF25a6F5E)[https://etherscan.io/address/0x62f49e904af170ea377f399aca76c13ff25a6f5e#code]

This contract allows trading of any tokens, between two counterparties without the need for a trusted escrow.

The instructions here assume the use of MyCrypto or a similar wallet to interact with the Ethereum blockchain.

Setting up a new trade

// Signing using hardware wallets such as Ledger or Trezor can be done using their documentation
