eth_getTransactionCount - opBNB RPC Method
Get account nonce on opBNB. Essential for transaction ordering for fully on-chain games, high-frequency DeFi, and cost-sensitive applications on BNB Chain.
Returns the number of transactions sent from an address on opBNB (the nonce).
Use Cases
- Transaction building - Get correct nonce for new transactions
- Account analysis - Count total outgoing transactions
- Nonce management - Handle pending transaction queues
- Wallet operations - Prepare transactions for fully on-chain games, high-frequency DeFi, and cost-sensitive applications on BNB Chain
Request Parameters
20-byte address
Block number or tag (pending for next nonce)
