x402’s $50B Scale Gives Solana an AI Payments Edge

Solana’s x402 protocol has processed roughly $50 billion in volume and connected about 150,000 merchant endpoints, according to a Solana Foundation and Coinbase webinar recap.

XRP Ledger has since documented its own x402 implementation settling in XRP and RLUSD, while Cardano remains a name attached to the conversation without comparable live adoption to show for it.But for smart money, the question isn’t whether AI agents can pay for web resources without a human clicking “checkout.” That part works.

The question is whether any single network converts that technical capability into recurring machine-to-machine commerce that translates into durable demand for its native token, rather than just routing stablecoins through infrastructure that happens to sit on top of it.

JUST IN: Solana handles 76% of all @x402 transactions.23.2M in four weeks. The next-largest network did 3.39M.
