AI Agents Drive Surge in x402 Wallet Refill Rate to 89%

A Chainalysis report indicates that two-thirds of newly funded x402 wallets made payments within an hour in the third quarter, up from just 4% a year earlier. The median time from initial funding to the first payment dropped to 18 minutes from 73 days in late 2025. Coinbase's x402 standard on the Base blockchain processed over 138 million transactions by July, supporting micropayments for AI model inference, code reviews, and data retrieval, with 87% of payments ranging between $0.0001 and $0.10.
