Coinbase Launches x402 Protocol for On-Chain Payments

Main Content

Coinbase has introduced the x402 protocol on May 6, 2025, leveraging stablecoin payments using the historically unused HTTP 402 “Payment Required” status code.

The x402 protocol could significantly impact on-chain transaction volumes and liquidity, particularly for stablecoins associated with Coinbase’s operations.

Coinbase Debuts Open-Source x402 Payment Standard

The x402 protocol is an open-source payments protocol, recently revealed by Coinbase, which facilitates stablecoin transactions via HTTP endpoints. The project showcases new methodologies of utilizing previously unused HTTP status codes.

The protocol, led by Coinbase’s CEO Brian Armstrong, aims for decentralized governance and will support community contributions. This payment facilitation marks an evolution from proposed models of micropayments to an implemented solution. Armstrong stated,

“We are committed to decentralized governance and community contribution for the x402 protocol.”

Stablecoin Use Expands with Chain-Agnostic Design

The protocol’s chain-agnostic design supports stablecoin use across multiple blockchains, open access through integration with projects. It could catalyze changes in transaction volumes, particularly for stablecoins like USDC. For further insights, you can refer to Wallet Documentation.

HTTP 402’s Revival: Implications for Pay-Per-Use Models

The use of the HTTP 402 status code reflects a long-standing interest in pay-per-use models. Prior efforts, such as Ethereum-based paywall solutions, offer parallels to this protocol’s potential impact.

Past implementations suggest possible outcomes for x402, with transaction volume increases likely if adoption follows trends seen with solutions like the Lightning Network. Its effectiveness will reveal in subsequent phases.
