Solana has established itself as the primary blockchain for the x402 micropayment protocol, which enables AI agents to conduct automated transactions using USDC. As of mid-August 2026, the network captured approximately 70% of the monthly protocol volume.
Over the 30-day period ending in mid-August 2026, Solana processed a total x402 transaction volume of around $24.24 million. The blockchain has recorded over 35 million cumulative x402 transactions to date.
On August 25, 2026, Solana outperformed the Base network in daily x402 transaction counts for the first time in six months. Base, developed by the Coinbase team, originally created the x402 protocol based on the HTTP 402 status code.
Market share for Solana in the x402 sector fluctuated throughout 2026, ranging from a low of 49.7% to a peak of 88%. Platforms such as Dexter and PayAI have secured notable market positions within the Solana ecosystem.
Total cumulative activity for the x402 protocol across all chains is estimated between 120 million and 187 million transactions. Analysts suggest these figures may be affected by measurement discrepancies or non-organic volume.
