Definition
Gas limit is a numerical setting that defines the maximum amount of computational effort a blockchain user is willing to allow for a specific on-chain action, such as sending a transaction or interacting with a smart contract. It acts as an upper cap on how much work the network may perform for that action before it is stopped.
In Simple Terms
Gas limit is a safety cap you set on how much work the blockchain is allowed to do for your transaction. It tells the network, “do not use more than this amount of gas,” helping prevent unexpected or unlimited processing for that on-chain action.
Context and Usage
Gas limit is commonly discussed in EVM-based blockchains when preparing or analyzing a transaction. It appears in transaction details, block explorers, and wallet interfaces as a key metric that shapes how much computation a transaction may consume within a block. Developers and users reference gas limit when describing on-chain activity and resource boundaries.
