Solana Surges to 70% Market Share in x402 Micropayments
Solana has become the dominant blockchain for x402, a micropayment protocol that enables AI agents to pay for APIs using USDC. As of August 2026, Solana processed about 70% of monthly x402 transactions, totaling $24.24 million in volume over 30 days.
This dominance is notable given the overall decline in x402 activity since 2025. Solana surpassed Coinbase's Base network in daily x402 transactions in August, highlighting its growing role in AI-driven micropayments.
However, transaction volume estimates vary widely, suggesting some measurement challenges or non-organic activity.
