Solana Tops Base in Daily x402 Transactions for First Time in Six Months

Base's six-month run as the clear leader in x402 micropayments has ended. Solana has moved ahead of Base in daily x402 transaction count, taking back the top position in one of crypto's fastest-growing payment categories. x402 revives an old piece of web plumbing: the HTTP 402 status code, long left largely unused as a placeholder for a future with native online payments. The x402 protocol, developed under the x402 Foundation, repurposes it into an open standard for onchain micropayments. It removes subscriptions, API keys, and traditional payment rails, relying instead on an automatic stablecoin transfer—most commonly USDC—when a service requests payment. On January 20, 2026, Solana logged 518,400 x402 payments in a single day, narrowly surpassing Base's 505,000, a lead of about 2.6%. Dollar volume was similarly close: roughly $34,600 on Solana versus $34,300 on Base. By mid-August 2026, Solana's advantage had widened sharply. It accounted for about 70% of monthly x402 volume across chains and had processed more than 35 million x402 transactions since launch. More broadly, Solana's total daily transactions routinely exceed 100 million, with peaks above 170 million in August 2026; Base typically processes several million. A key catalyst came on August 21, 2026, when Ramp announced x402 AI agent wallet capabilities on Solana, aimed at its network of more than 70,000 businesses. Ramp positions x402 as automation-ready payments infrastructure for enterprises rather than a crypto-native product pitched to DeFi users. With nearly all x402 payments settling in USDC, the protocol is also emerging as a notable driver of stablecoin velocity on the chain that captures the bulk of usage.
