Testnet
x402 Hub is live on Base Sepolia testnet. All platform features are available for testing and development. We'll move to mainnet when the platform is ready — no fixed timeline.
Testnet data may be reset periodically. Use testnet to build, experiment, and integrate — don't rely on it for permanent records.
