# Gas Limit

## Definition

The maximum amount of gas units you are willing to consume for a transaction. Gas units measure computational work — complex operations (like a multi-hop DEX trade) use more gas than simple transfers. If your gas limit is set too low and the transaction runs out of gas mid-execution, it fails (reverts) and you lose the gas spent up to that point. Wallets estimate gas limits automatically, but you can adjust them manually.
