# Gas Many networks require the expenditure of a small amount of cryptocurrency, known as **Gas**, in order to facilitate the sending of assets on that [blockchain](/glossary/definitions/decentralization/blockchains.md). Gas is the term used to describe the unit of measurement for the amount of computational power required to complete a transaction on a blockchain. In order to send assets on a blockchain, a user must pay a certain amount of gas to cover the cost of the computation. This is typically done using the blockchain's native cryptocurrency, such as Ether for the Ethereum blockchain. The amount of gas required to complete a transaction can vary depending on the complexity of the transaction and the current state of the network. The gas is used to pay for the computational resources required to process the transaction and add it to the blockchain. Without gas, transactions on a blockchain cannot be completed. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
