Frequently asked questions

Updated June 2026
Does x402 work with Solana? +

Yes. While x402 originated with Base support, the protocol has expanded to support multiple networks, including Solana. Several Solana-native facilitators are in active development, drawn by its fast settlement times.

Is x402 safe to use? +

The protocol itself is a well-reviewed open standard with no inherent flaw, but on-chain settlement is generally final — there's no chargeback mechanism the way there is with card payments. Treat any payment as irreversible once sent.

Separately: there is no official x402 token. Anything sold under that name is unrelated to the real protocol and worth treating with suspicion. See our full scam-awareness guide for more.

Do I need a cryptocurrency wallet to use x402? +

Yes — paying an x402-gated request requires a wallet that can hold and sign for the required stablecoin (usually USDC) on the relevant network. See our wallet setup guide for a walkthrough.

Is there an official x402 cryptocurrency or token? +

No. x402 settles payments in existing stablecoins, primarily USDC. There is no official x402 coin or token — anything claiming otherwise is not part of the actual protocol.

Who controls the x402 protocol? +

No single company. It's governed by the x402 Foundation, hosted under the Linux Foundation, co-founded by Coinbase and Cloudflare, with a broad membership that includes Google, Visa, Stripe, AWS, and others.

How is x402 different from a subscription or normal API billing? +

Traditional billing requires an account and usually a recurring or pre-paid arrangement, because card processing has fixed costs that make sub-cent charges impractical. x402 charges per individual request with no account needed, making genuinely tiny payments viable for the first time.

Can I use x402 to charge for access to my own API or content? +

Yes, via a facilitator that handles verification and settlement on your behalf. See our checklist for API providers before integrating.

What happens if a payment fails or I'm overcharged? +

The protocol itself doesn't include a dispute or refund mechanism — settlement is generally final. Any resolution process is up to the individual resource server or facilitator's own policy, so it's worth checking that before relying on a service for anything beyond small, low-stakes amounts.
