GAS is a unit of measurement used when executing smart contracts on blockchain platforms (especially Ethereum and its compatible chains). It represents the cost required to perform each operation. Users must pay GAS fees when initiating transactions or executing smart contracts to compensate miners for processing and verifying the transactions. The design purpose of GAS
