Overview

Trustless peer-to-peer asset exchange platform

Signex is a trustless peer-to-peer (P2P) exchange platform that enables two wallets to swap assets (ERC-20 tokens and ERC-721 NFTs) directly, securely, and without an intermediary.

Assets are escrowed in a smart contract and only released when both parties confirm. The initial deployment targets Base L2 to maximize low gas costs and developer friendliness.
