Simple Swap

Summary

Simple Swap allow users to execute trades without paying gas fees or slippage. Orders are placed securely via EIP-712 signed data, supporting multiple inputs and multiple outputs in a single transaction. Trades will be executed when an Odos route is found that covers both the specified output amount and the gas cost. Users receive exactly the amount specified in the order once it is filled, with no slippage or hidden gas fees, aside from initial contract approval.
