Coinbase's x402 Tops 100 Million Transactions on Base

The milestone signals growing use of USDC for autonomous AI payments, highlighting concentration risk on Base

Overview

  • Chainalysis reported Thursday that wallets using the x402 protocol have produced more than 100 million transactions on Base since the protocol launched in May 2025.
  • Official protocol data from x402.org shows 72.41 million transactions and $24.24 million in settled volume in the most recent 30-day window.
  • x402 embeds USDC payments into web requests so software agents can pay for APIs or services directly without user billing accounts or API keys.
  • Major integrations and features have followed the surge, including Stripe support on Base, AWS Bedrock AgentCore Payments, Base MCP for agent-linked accounts, Agentic.market, and new batch settlement options.
  • Analysts warn early spikes were driven in part by a PING memecoin mint and that transfers above $1 now make up about 95% of value moved, a shift that raises questions about concentration and how broadly x402 activity will spread beyond Base.
