Transactions submitted to the network will complete in success or failure. The vast majority of the time, transactions will complete successfully. However, on occasion, transactions fail for one reason or another.
While the specific reasons a transaction has failed depend on the smart contract you are engaging with, we've outlined the most common errors and error codes as they are defined in our core marketplace contract.
