Smart Contract Revert Risk
Smart contract revert risk refers to the possibility that a transaction fails to complete, causing all state changes within that transaction to be rolled back to their original state. In the context of flash loans, this is a safety feature that prevents the protocol from losing funds if a borrower cannot repay the loan.
However, for the user, a revert means that any gas fees spent on the failed transaction are still consumed by the network validators without any successful outcome. This risk is often associated with changing market conditions where an expected arbitrage profit disappears between the time the transaction is submitted and the time it is mined.
Users must implement robust error handling to minimize these losses.
