What Is Gas Limit in Ethereum?

In the Ethereum network, transactions are processed and verified by nodes in the network through a process called mining. In order to successfully mine and process a transaction, a miner needs to have access to computational power, an incentive to process the transaction, and most importantly – gas.

Gas is a unit of measure that is used to determine how much computational power is required to process a transaction or execute a smart contract. The more complex the transaction, the more gas it will require.

The gas limit is the maximum amount of gas that a transaction can use.

NOTE: WARNING: Before attempting to understand and use Gas Limit in Ethereum, you must have a thorough understanding of the Ethereum blockchain and its associated technologies. If you are unfamiliar with these topics, it is strongly recommended that you first seek out appropriate resources to gain familiarity before continuing. Additionally, you should be aware that incorrect use of the Gas Limit can lead to unexpected or unfavorable results, including financial loss.

If a transaction requires more gas than the gas limit, then it will not be processed by miners and will fail. This is why it’s important to set the gas limit correctly when sending a transaction – if it’s too low, your transaction will fail; if it’s too high, you’ll waste money on gas that wasn’t used.

The gas limit can be set manually by the user or wallet when sending a transaction. However, most wallets will automatically set the gas limit based on the current gas prices and estimated gas usage of the transaction.

To summarise, the gas limit is simply the maximum amount of gas that can be used in a single transaction. It’s important to set this correctly when sending transactions, as if it’s too low your transaction will fail, and if it’s too high you’ll waste money on unused gas.
