Accept crypto payments.
0.4%, compliance included.
Suward is a payment gateway for accepting stablecoins and major cryptocurrencies. One API, a growing list of assets across multiple networks. No payment is credited on a single block confirmation, and every fee is quoted before your customer confirms.
No monthly fee. No plans. Accept your first payment right after sign-up.
How it works
From checkout to settled funds in three steps
Create a payment
Call the API or use the hosted checkout page — no frontend work required. Your customer sees the exact amount to pay, with every fee quoted before they confirm.
Customer pays
Every incoming transaction is screened for AML and sanctions risk before it touches your balance.
You are settled
The payment reaches Accepted — enough confirmations to ship the order or credit the user. Then Success — irreversible, ready to withdraw. You always know which stage your money is at.
Two modes, one API
Two ways to accept — matched to how your business works
Payment lifecycle
Transaction observed on-chain. Nothing is credited yet — never on a single block confirmation. If the chain reorganizes, affected payments are re-verified automatically while they are still confirming.
Enough confirmations to act on — ship the order, credit the user.
Irreversible. Ready to withdraw. Stage change and balance change happen together or not at all.
Settlement
Settlement you can verify
Most of what can go wrong in crypto payments goes wrong between “paid” and “credited.” Suward closes that gap with mechanics, not promises. No payment is credited on a single block confirmation — Accepted means enough confirmations have accumulated to act on safely. If a chain rewrites its recent history, affected payments are re-verified automatically while they are still confirming — before you are told to act, not after. Your accepted and final balances are updated as one operation, so balances structurally cannot go negative. And a retried request never creates a duplicate payment. All of it is documented publicly — you can check every claim before you sign up.
How settlement worksCompliance built in
Compliance is part of the payment, not an add-on
Every incoming transaction is screened before it is credited to your balance — screening is part of the pipeline, not an add-on you can skip. Basic screening is included in the 0.4% rate. Need deeper checks? Extended screening runs every transaction through independent blockchain-analytics providers — $0.45 minimum per payment, switchable per organization, project, or single payment. Sanctioned jurisdictions are blocked automatically at every level, and suspicious patterns are monitored continuously.

Built for builders
Integrate in an afternoon. Test it on real networks.
REST API with SDKs for TypeScript and Go, and a plain REST integration in any other language. A hosted checkout page if you’d rather not build one. Webhooks are cryptographically signed, so a notification can’t be forged. API keys come with limits, rotation, and instant revocation. API changes are backward compatible — an integration you ship today keeps working. And you can test your integration on real networks with Suward test tokens — free, valueless assets that run through the same pipeline as live payments. Minting is open to anyone; the full flow (payments, webhooks, dashboard) runs on a free account.
import { SuwardSDKClient } from "@crylabsorg/suward-sdk";
const suward = new SuwardSDKClient({
apiKey: process.env.SUWARD_API_KEY,
});
const payment = await suward.payments.createPayment({
amount: "1000000000", // integer string, smallest unit
asset: "USDT_ARBITRUM",
externalId: "order_4821", // makes the call idempotent
});
// every fee quoted before your customer confirms
console.log(payment.networkFee);
console.log(payment.paymentPageUrl); // hosted page, no frontendIndustries
