This discrepancy can arise from various factors, including concurrent transactions, cancelled transactions, or network congestion. Manual Overrides To resolve the issue, users can attempt the following manual overrides: Reset the MetaMask account Increase the gas price to prioritize transaction processing Use the following JSONRPC method to reset the nonce: json { "jsonrpc": "2.0", "method": "eth_resetNonce", "params": ["0x...account_address", "0x...new_nonce"], "id": 1 } Consider utilizing an external console for more advanced troubleshooting and direct blockchain interaction.
