In blockchain technology, especially in Ethereum or EVM (evm - ethereum virtual machine) compatible networks, the specific amount of service charge that has to be paid for each transaction or smart contract execution is called 'gas fee'. Blockchain is not just a simple database, but it is a decentralized global computer. As a result, the computing power or processing power of the network is consumed for every small or big task like executing a transaction, creating a new smart contract, or updating data in a decentralized application (dapp). This system of paying fees has been created as compensation for the hard work and energy used by these validators or miners and to stop spamming or abuse on the network. The main mechanism for calculating gas fees depends on the complexity of the task and the demand of the network. Gas fees are usually calculated based on two main components: 'Gas Limit' and 'Gas Price'. Gas limit is the maximum amount of processing power that can be consumed to complete a specific task. For example, sending cryptocurrency from a simple wallet to another wallet requires a specific gas limit of 21,000 units. However, a transaction on a complex smart contract or DeFi platform requires a much higher gas limit. After the EIP-1559 update of Ethereum, a groundbreaking change has occurred in the gas fee calculation formula. Currently, the basic formula for calculating gas fees is: Total Gas Fee = Gas Limit × (Base Fee + Priority Fee). Here, 'Base Fee' is the minimum fee determined by the algorithm based on the demand for the current block of the network, which is burned at the end of the transaction. And 'Priority Tip' is an additional tip given to the validator, which allows the validators to process that transaction faster on a priority basis. If a transaction consumes less gas than the gas limit, the excess gas is automatically returned to the user's account. Gas Master or gas relay network plays a role in making this complex gas management easier for ordinary users and projects. Gas Master is basically a third-party or protocol-level solution that manages or sponsors gas fees on behalf of users. For example, sometimes a user has a primary token to transact with, but does not have a native token (such as ETH or MATIC) to pay the gas fee. Gas Master or gasless transaction protocols complete the transaction by deducting the fee from the gas master's own account through meta-transactions. Ultimately, the gas fee calculation mechanism maintains the balance of a blockchain network and keeps it economically secure. On the other hand, the Gas Master system is making the use of blockchain and Wave 3.0 technology easier and more acceptable to the general public by removing the obstacles of high gas fees and complexity.
