Solana has overtaken Base in daily x402 on-chain transactions for the first time, marking a significant shift in the competition for automated stablecoin payment rails. On Sunday, January 11, 2026, Solana recorded 518,400 x402 payments, edging out Base's 505,000 payments, according to on-chain data from Artemis Analytics.
The margin of 13,400 transactions, while slim, represents a symbolic leadership change in a rapidly growing sector. Combined, the two networks processed over 1,023,000 x402 payments in a single day, turning stablecoin usage into a measurable throughput race. This crossover highlights how quickly automated payment traffic can rotate between networks based on integration availability and execution predictability.
On the same day, x402 transaction volumes on Solana reached $34,600, slightly above Base's $34,300, bringing the total x402 transaction volume across all blockchains to $69,000. Payment volume in agent-to-agent services led at $49,600, followed by data-as-a-service transactions at $15,000.
The x402 protocol has seen explosive growth, processing over 100 million payments across several applications by the end of 2025 and recording more than $600 million in annualized payment volume across all supported blockchains. Notably, over 50% of all x402 payment volume flows through the Coinbase facilitator, though other providers are gaining traction.
Cumulatively, Base still dominates in x402 volume with 119 million transactions and over $35 million in payment volume. Solana follows with 38.6 million cumulative transactions and $7.9 million in payment volume, while Polygon PoS has processed 924.1 million transactions with $3,100 in volume.
Industry forecasts suggest substantial future growth. Galaxy Digital predicted in December that the x402 payment standard will reach 30% of Base's daily transactions and 5% of Solana's transactions in 2026. Venture firm a16z forecasted that the x402 protocol could reach a $30 trillion market share within five years.
The protocol's development is backed by major industry players. In September, Coinbase collaborated with Cloudflare to establish the x402 Foundation, aiming to simplify online payments with a new, open Internet standard. Coinbase CEO Brian Armstrong stated the initiative will "ensure the standard remains open and can be used fairly by any company in the world." Cloudflare's CEO Mathew Prince championed the work, noting that standardization could overcome geographic, currency, and formatting barriers that have hindered payment adoption.
