How this service works
EVM Nonce (bsc). BNB Chain (BSC) account nonce for any address: confirmed nonce and pending nonce (a gap means transactions are still waiting in the mempool). Use it before sending a transaction or to detect a pending one.
Output
Returns the current transaction nonce (account transaction count) for the specified address on the BSC EVM network, typically as an integer representing how many transactions have been sent from that address.
Example use cases
Pre-transaction nonce verification
“Before I broadcast my next transaction on BSC, can you look up the current on-chain nonce for 0xAbCdEf1234567890AbCdEf1234567890AbCdEf12 so I can set the right nonce and avoid replacement errors?”
Smart contract deployment nonce check
“I need to deterministically compute the address of a smart contract I'm about to deploy on Binance Smart Chain — can you fetch the current nonce for wallet 0x1234567890abcdef1234567890abcdef12345678?”
Wallet activity audit
“How many transactions has the BSC address 0xDeAdBeEf0000000000000000000000000000Dead sent so far on the Binance Smart Chain? Fetch its on-chain nonce for me.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/bsc/nonce/:address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the on-chain transaction nonce specifically for a BSC (Binance Smart Chain) address, especially before signing and broadcasting a transaction, deploying a contract, or auditing account activity. Prefer it over Ethereum mainnet nonce endpoints when working exclusively with BNB Chain.
Side effects
- Invalid or malformed address returns an error response
- Non-existent address (no transactions) returns nonce of 0
- Network or RPC node outage may cause timeout or 5xx errors
- Incorrect chain queried if address exists on multiple EVM chains but nonce differs
