Gas Limit

Gas limit refers to the maximum amount of computational work or energy a user is willing to spend on a transaction or smart contract execution on the Ethereum blockchain. It acts as a cap to ensure the transaction doesn't consume more resources than expected, preventing potential failures or excessive fees. If the gas used exceeds the limit, the transaction fails, but the spent gas up to that point is still paid. Setting an appropriate gas limit ensures the transaction completes successfully without wasting funds or overpaying.
