The highest amount a cryptocurrency user is willing to spend while submitting a transaction or executing a smart contract function on the Ethereum blockchain is referred to as the "gas limit." The maximum value that the transaction or function may "charge" or "take" from the user is determined by the gas limit, which is used to calculate these fees in units of gas. As a result, the gas limit functions as a security feature that stops huge fees from being unjustly charged as a result of a smart contract defect or error. While some wallets and services set the gas prices and cap automatically, in some situations users can also manually modify them to suit their needs. A typical Ether (ETH) transaction would typically have a gas limit of at least 21,000 units. The process will go significantly faster if the gas cap and gas pricing (Gwei) are set to higher values. Even still, speedier surgeries will probably cost more. An extremely low gas cap and price, on the other hand, would be dangerous since transactions could fail or take too long to confirm. The cost of gas, however, is what actually determines the worth of transaction fees. Since the gas limit is merely a definition of the maximum value, the gas price has more of an impact. In other words, the quantity of Ether required to complete a transaction is equal to the gas price (in Gwei) times the gas limit.
