An Open Invitation: Settle Your x402 Service Through SML

Most x402 services settle through somebody else's facilitator — usually the biggest one, because it was there first. This is an open invitation to settle through ours instead.

ScriptMasterLabs runs two x402 facilitators. Between them they cover five networks. Fifteen of our own services are already settle-proven on these rails — those proofs are our own traffic, so we label them SELF-PROOF rather than dress them up as outside adoption.

The two doors

OMNIGATE — open, self-serve, no key. Base and Arc. The fee is $0.005 USDC per settlement, collected inside the settlement itself, so no account, no signup, and no trust in us is required. Point your service at the gateway and settle. Discovery and the payment contract are public, and the read-only tools are free.

402Proof — partner-keyed, by design. XRPL and Xahau (Solana rides the same fleet through the sidecar door). The fee is $0.0100 per settlement in the settled asset, and on XRPL it accrues rather than being collected inline — which is exactly why this door is keyed: an open door there would extend uncollectable credit to anonymous third parties. A partner key takes one email.

No custody, either way. Both facilitators authorize and settle to your own receiving wallet. SML never holds your funds, never takes a balance, and never sits between you and your money after the settlement lands.

Who this is for

You, if you run an x402-priced service today and:

• settle through a third-party facilitator you'd rather not depend on,
• want XRPL or Xahau settlement without building the rail yourself,
• or haven't wired settlement up at all yet and want a door that's already proven — our 15 settle-proven services run on exactly these rails, at exactly these prices.

If the open door is all you need, you don't even have to talk to us. OMNIGATE is self-serve.

How to get a partner key

For 402Proof (XRPL / Xahau), email [e-mail] with three things:

1. your service's base URL,
2. the rail you want (XRPL or Xahau),
3. your receiving wallet address.

You'll get a reply within one business day. The full terms for both facilitators live on one page: settle-through-sml. Everything else we sell — the whole catalog, priced — is on the SML store page.

You may not know you're interested until somebody asks. Consider this the ask.
