Programmable Payment Policy.
Verified Before Execution.

PAY.ID lets you define payment rules off-chain, evaluate them deterministically, and enforce the decision on-chain or in backend systems.

Payment Policy, Not a Payment Rail

PAY.ID separates decision from execution, making payment logic auditable, upgradeable, and verifiable.

Any rule failure, invalid input, or engine error results in a deterministic REJECT.

Rules are evaluated off-chain and enforced using cryptographic decision proofs.

Works seamlessly with smart accounts, DAOs, and traditional backend systems.

A simple flow designed for safety, composability, and verification.

Construct a payment context containing sender, asset, amount, and chain.

Rules are evaluated off-chain inside a deterministic WASM engine.

The signed decision is verified before any transaction is executed.

Open-source, protocol-first, and built for developers.
