Gas Limit
Also known as: Maximum Gas, Gas Cap, Transaction Execution Limit
The maximum amount of computational effort a user is willing to spend on a blockchain transaction.
Gas limit defines the upper boundary of computational steps a blockchain transaction can consume. It protects users from overspending and helps nodes manage network resources. If a transaction exceeds its gas limit, it fails but still consumes gas. Users can adjust the gas limit to accommodate complex operations like deploying contracts or interacting with dApps. Setting it too low may cause failure; too high may waste ETH if misconfigured. Developers estimate gas usage to set appropriate limits, and some dApps include recommended values automatically.
