The problem today

Agents can pay. Just not safely, or everywhere.

Every big player shipped an agent payment protocol. None of them talk to each other.

x402

No refunds or disputes

When an agent pays for the wrong thing, there is no way back.

AP2

Approvals, but no money

It proves a human said yes. It never actually moves the funds.

Every protocol

Nobody routes between them

An agent speaking one protocol cannot pay a merchant on another.

Stablecoins

Going mainstream fast

OUSD, co owned by Visa, Mastercard, Stripe, Shopify and Coinbase, launched 30 Sep 2026.

Splintr closes every one of these gaps.

Universal router

Any agent. Any protocol. One integration.

Splintr speaks x402, MPP, ACP and AP2. An agent pays in whatever protocol it knows. We translate, find the best route, and the merchant gets paid on the chain they chose.

  • Accept every agent protocol from one endpoint
  • Automatic translation between protocols
  • Best route picked for cost and speed

Agent wallets

Give your agent a wallet. Keep the keys to the rules.

Fund a wallet, set the rules once, and let your agent spend inside them. Every payment comes with a signed receipt that proves you approved it.

  • Daily and monthly spending limits
  • Approved merchant lists
  • Ask a human above any amount you set
  • One tap freeze if anything looks wrong
Refunds, escrow and disputes

Agent payments with a safety net.

The piece every agent protocol is missing. Funds wait in escrow until delivery, and either side can open a dispute.

Agent paysEscrow holdsDeliveredReleasedproblem?ClaimReviewRefunded
  • Buyer protection on every agent payment
  • Merchants get paid the moment delivery is confirmed
  • Clear claim and review timeline
  • A full audit trail for both sides
Independent AI jury

Three independent AIs. One accountable ruling.

When agents disagree about a payment, GPT, Claude and Gemini each review the evidence independently. No single model gets the final say.

DisputeGPTAClaudeAGeminiATally3 to 0Advisorydecision
  • GPT, Claude and Gemini review independently
  • All three must agree on an advisory ruling
  • Split votes or incomplete reviews go to a human
  • Up to three trials before a final ruling
  • Every vote and reason is saved for both sides
  • Tested on over 5,000 dispute cases in beta
Trial 1

First hearing

Every judge reads the claim, the receipts and the delivery proof on its own, then votes.

Trial 2

Appeal

Either side can add new evidence. The panel hears the case again from scratch.

Trial 3

Final ruling

One last hearing. A close vote always goes to a human before money moves.

Tested on over 5,000 cases in beta. AI rulings are advisory; human approval and verified escrow are required before live funds move.
