according to Dune data, the number of transactions in the x402 protocol increased by 492.63% compared to last week, reaching 156,492 transactions, setting a new historical high.
x402 is an open-source payment protocol launched by Coinbase in early 2025, implementing a blockchain-independent micro-payment system based on the HTTP 402 status code. The protocol is specifically designed for AI agents and autonomous payments, supporting instant settlement using stablecoins such as USDC, without the need for account registration, subscription, or complex signature processes.
