X402 Ecosystem Expands As Solana Becomes Number-one Network For...

Solana has quietly become the busiest chain for x402 payments, clocking an all-time high $380,000 in daily volume and a 750% weekly jump.

Solana just logged its biggest week yet for x402, with daily payment volume hitting an all‑time high of about $380,000 on Sunday and about 750% week‑on‑week growth.

The latest activity lifts Solana to the most active network by dollar volume for the transactions, showing how fast the AI‑agent payments narrative is turning into measurable onchain flow.

The rise of x402 payments on Solana marks a turning point for the HTTP-402-based protocol, with pay-per-request stablecoin transfers now flowing through facilitators at a pace that resembles less a speculative spike and more the early contours of machine-driven demand.

Instead of wash trading or airdrop farming, bots and agents are beginning to hit Solana for actual services.

While the absolute numbers remain small compared with decentralized finance (DeFi) and trading flows, they offer a clean datapoint that real customers, and not just speculative capital, are starting to settle recurring payments on Solana.

What makes this week’s move more striking is that x402 was built for the internet’s back end, not for humans chasing the latest token ticker.

The standard lets APIs, apps, and AI agents respond with a 402 “Payment Required” code, settle a gasless USDC (USDC) transfer on a chain like Solana under the hood, and then serve the content or compute the requester is paying for.

For Solana, becoming the busiest x402 venue strengthens the claim that low fees and high throughput are useful for machine and API micropayments, not just memecoins and high‑frequency trading.
