The eth_getTransactionCount method returns the number of transactions sent from an address (the account nonce) on the Optimism network. 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.

blockParameter	string (required)	Block number in hex or tag (latest, earliest, pending)
