# x402 Foundation

x402 was originally incubated at Coinbase. April 2nd 2026, the
[x402 Foundation launched under the Linux Foundation](https://x402.org/linux-foundation-announces-operational-launch-of-x402-foundation-to-standardize-internet-native-payments-for-ai-agents-and-applications/)
and Coinbase completed its contribution of the protocol. x402 is now developed under open,
vendor-neutral governance, so the payment layer stays interoperable and free of lock-in to any
one provider.

Forty organizations joined as members at launch, spanning finance, cloud infrastructure, and
payments. Premier members include Amazon Web Services, American Express, Cloudflare, Coinbase,
Google, Mastercard, Shopify, Solana Foundation, Stripe, and Visa.
