kaia_getTransactionCount

The eth_getTransactionCount method returns the number of transactions sent from an address (the account nonce). This method is essential for creating new transactions as the nonce must be correctly set to ensure proper transaction ordering and prevent replay attacks.

Wallets use this to determine the next nonce value when constructing and signing new transactions. The nonce ensures transactions from an account are processed in order and prevents the same transaction from being executed multiple times. Developers use this when preparing transactions, tracking account activity, and ensuring transaction sequencing. Using 'pending' as the block parameter includes pending transactions in the count, which is important for sending multiple transactions in quick succession.

Parameters

parameter	type	description
address	string (required)	The address to get transaction count for (20-byte hex string with 0x prefix)
blockParameter	string (required)	Block number in hex format (e.g., '0x10d4f') or one of the string tags: 'latest' for confirmed transactions, 'earliest' for all transactions since genesis, or 'pending' to include pending transactions in the mempool

Return Object

field	type	description
result	string	The transaction count (nonce) for the address encoded as a hexadecimal string. This represents the number of transactions sent from this address. For a new account with no transactions, this returns "0x0". Use this value as the nonce for the next transaction from this address.
