Supported Networks
RelAI x402 is live across multiple chains — with a unified payment layer and consistent developer experience.
You don't need to handle network differences. The protocol abstracts execution, settlement, and gas.
Overview
RelAI currently supports:
All payments are executed in USDC (or compatible stable tokens depending on network).
Why multi-chain matters
Different use cases require different tradeoffs. RelAI routes payments across chains without changing your integration.
Networks
How it works across chains
RelAI normalizes all flows — same integration, any chain.
Choosing a network
You don't need to pick just one. Typical setup:
RelAI handles routing and settlement. You don't need to change your API code to add more chains.
