Mechanism

The fee is taken when we sweep. Not later. Not on a dashboard.

Fee taken on sweep. Net lands in your wallet. Identified by a callback you control. Register only if you want stats and cashflow.

01
Create
Call /{ticker}/create with your wallet and a unique callback URL. We return address_in. Same callback always maps to the same address.
02
Detect
Customer pays on-chain. You get a pending webhook from mempool, then a confirmed webhook after your confirmation target.
03
Split & forward
On sweep we deduct network fee + your current volume tier. Net lands in your wallet. Webhook carries fee_percent, value_forwarded, and your callback_id.

API

Drop-in shape. Unique callback ID built in.

Ticker in the path. Callback in the query. Identify the order with callback_id — we echo it on every webhook.

No API key required for create / info / estimate
HMAC-SHA256 webhook signatures
Respond *ok* — we retry with backoff if you don’t
Volume tier is computed on destination address per chain

FAQ

Straight answers for ads, sales, and legal review.

Do I need to register?

No for the payment API. Register if you want a dashboard with 30-day volume, fees, and cashflow on the destination wallets you add.

How do you know my 30-day volume without an account?

Confirmed sweeps to the same normalized destination address on the same chain are aggregated. The dashboard is a view on that same key.

Which assets at launch?

Ethereum, BNB Smart Chain, Arbitrum and Polygon — same token set as CryptAPI on those four EVMs (USDT, USDC, DAI, ARB, LINK, and the rest). BTC, Solana and Tron are later.

Point the base URL at ChainSplit. Keep the rest of your shop.
