x402 Payment Protocol Lands on Etherlink, Opening the Door to Agentic Payments
Singapore, Singapore, March 6th, 2026, Chainwire
x402, the open-source internet-native payment protocol developed by Coinbase, is now supported on Etherlink, the EVM-compatible interface for Tezos. The integration, dubbed Tez402 and led by TZ APAC, makes it possible to turn any Etherlink API into a pay-per-request endpoint using on-chain stablecoin payments with no subscriptions, invoicing, or intermediaries.
x402 enables instant, low-cost crypto payments for digital services, purpose-built for scenarios where traditional payment methods are too slow, too expensive, or simply don’t fit. x402 works by reviving the dormant HTTP 402 “Payment Required” status code, enabling servers to request crypto payments directly through standard HTTP headers. TZ APAC has adapted the existing Coinbase implementation for practical, end-to-end use on Etherlink, adding a facilitator and a Permit2 proxy so that payments can be made with ERC-20 tokens while remaining non-custodial and destination-locked.
“For builders and users alike, this brings 402-native payments to Etherlink in a practical way. It turns APIs into payment-aware endpoints, enables settlement in compatible tokens on-chain, and creates the kind of internet-native commerce rail needed for an emerging agentic economy,” said David Tng, Managing Director of TZ APAC.
The release targets a broad range of use cases across the ecosystem: API and SaaS teams looking to add pay-per-request without managing subscriptions, Web3 applications monetising endpoints on Etherlink, and wallet, SDK, and infrastructure teams seeking a concrete x402 integration target. The implementation is also intended to serve as a known-good reference for hackathon teams and ecosystem builders.
The x402 integration is available now on Etherlink mainnet. Projects and developers looking to accept x402 as a payment method can get started today by following the quick start guide. They can choose to settle transactions using the TZ APAC facilitator or integrate their own facilitator. Learn more and begin implementing x402 here: https://bit.ly/Tez402_PR
