📄️ Introduction
The Stablecoin Stack is an open architecture for processing stablecoin payments on Ethereum-compatible networks. It is built on a single central proposition: that cryptographic signatures are a superior foundation for payment authorisation compared to identity-based delegation models, and that the tooling to make this practical for everyday users is both achievable and urgently needed.
📄️ Payment Submission
Payment submission is the process by which a Client Wallet constructs a signed payload and delivers it to the Payment Processor API, which validates it and broadcasts the corresponding transaction on-chain.
📄️ The Settlement Contract
The Settlement Contract is the on-chain trust anchor of the Stablecoin Stack. It is a Solidity smart contract deployed on Ethereum-compatible networks that serves as the authoritative execution layer for all payment operations.
