See the full lifecycleFrom checkout to a balance you can trust.
- 01
Create
Create a payment with one API call. It’s idempotent, so a retry never doubles it.
- 02
Unique address
Suward forges a fresh deposit address bound to that one payment. No address reuse.
- 03
Monitor
We watch the network and count confirmations, one block at a time.
- 04
Safe → Finalized
Status climbs Pending → Safe → Finalized, protected against reorg the whole way.
- 05
Balance
Funds land in your atomic balance, split into safe and accepted. Never negative.
Built for money you can trust
Everything you need to accept stablecoins safely.
02
Reorg protection
Pending → Safe → Finalized. We re-verify and hold until the configured finality threshold is met.
PendingSafeFinalized
03

04
Hosted checkout
A ready checkout with a QR code, a live mempool watch and a countdown. No UI to build.
05
Multichain
One integration reaches all 7 EVM networks, with USDT, USDC and native assets.
06
API-first
One REST API with idempotency, managed API keys that carry rate limits, and a public sandbox.
Pricing
0.4% + min $1 per payment. That’s the whole headline.
On larger payments that lands below most public competitors — Coinbase Commerce ~1%, CoinGate 1%, BitPay ~1.5% + 25¢, NOWPayments 0.5%/1%, Stripe Crypto ~1.5%. On small payments the $1 minimum pushes the effective fee higher, and the calculator shows you exactly where. The network fee goes to the chain — Suward never adds it on top.
