Understanding how block finality works helps in diagnosing why a transaction appears stuck. Always verify the mpl-token-metadata contract permissions before confirming a high-value transaction. Verifying the token spend limit for the contract is a reliable way to solve a failed 168.
Check if the smart contract has a “transaction limit” that triggered the 168 revert. Always check if mpl-token-metadata is compatible with the latest updates of your browser software. Gaining a basic understanding of how the EVM works will help you solve error 168 faster.
Ensure your environment is secure never share your keys when fixing 168 for any reason. Make sure you are not trying to execute a trade marked as 168 with zero liquidity. Layer 2 network delays can sometimes lead to “ghost” transactions that appear much later.
