BNB Smart Chain wallet API for business
Accept and pay out BNB and BEP-20 stablecoins from wallets you control. BNB Smart Chain runs on the same EVM engine as Ethereum in Guveno, so your integration, your addresses and your signing code carry over unchanged.

How BNB Smart Chain deposits are credited
BNB Smart Chain produces blocks in seconds, so Guveno waits for a fixed depth before calling a deposit final, and re-checks recent blocks for reorganizations until then.
A token deposit is credited only from a Transfer event emitted by the token contract to your address, and only when the transaction succeeded. A token transfer that returns false without reverting moves nothing, so it credits nothing.
Each deposit reaches you as a webhook: deposit.detected while it is pending, then deposit.confirmed with the exact amount delivered, which is the signal to credit it.
Sending BNB and tokens
The same prepare, sign and broadcast flow as Ethereum, with BNB paying the network fee.
Every withdrawal is prepared by the API, signed with key material only you hold, and broadcast once. A send whose outcome is unknown is never retried blind. See withdrawals and hot wallets for automated payouts.
