What Is a ‘Gas Limit’ and Why Is It Necessary for Smart Contracts?

The gas limit is the maximum amount of gas a user is willing to pay for a transaction. It is necessary for smart contracts to prevent infinite loops or excessively long computations from running indefinitely and consuming all network resources.

By setting a limit, the user ensures that if the computation exceeds this cap, the transaction fails, and the network is protected from resource exhaustion. Unused gas is refunded.
