Custody, collections and payouts
The infrastructure under your on-chain product. Live, and testable today.

The problem
Teams building on-chain burn time running nodes, indexers and key management instead of shipping their product.
How CowriePay helps
One isolated workspace per entity
Provision one HD wallet per end user on TRON, BNB Chain and Ethereum, in a single API call. Your balances split into available, pending and locked.
Credit at on-chain finality
Real-time detection, confirmations per chain, source-of-funds screening before credit with funds held if screening cannot run, and automatic consolidation.
Payouts and evidence
Payouts by API with signed webhooks; every sensitive action is recorded and every state is timestamped, retained for ten years.
Who it is for
Crypto-native products, exchanges and on-chain treasuries.
Products used
The stablecoin settlement layer, run end to end
CowriePay operates the receipt, screening, consolidation and dispatch of stablecoins, with the controls a bank expects. Two ways to integrate: direct, from the dashboard and the API, or white-label, inside your product. The fiat leg runs on the settlement partners of your choice, and the customer relationship stays yours.
Compliance built into every flow
Frequently asked questions
Who holds the keys?
CowriePay manages key custody and signing for you. Signing is isolated from the API layer, and each workspace has its own HD derivation, so you never handle keys yourself.
Does the sandbox run on real chains?
Yes. Real testnets on TRON, BNB Chain and Ethereum, with a built-in faucet to pre-fund your test wallets in one API call.
Which SDKs are available?
Node.js, Python and PHP, officially published and maintained, with a full OpenAPI reference.
