### Gas Fee

Gas is a unit of computational cost for processing a transaction. This has two main purposes in that it enables to make sure transactions not consuming too much computational resources and to prevent unnecessary spamming from the users. 

`Gas fee` is calculated by 

$$
Gas Fee = Gas Amount \times Gas Price.
$$

The minimum amount of `Gas Amount` is determined according to the transaction. There are the recommendations of Gas Amount for the kinds of transactions. For example, for a transaction of deposit and claim, the recommended gas is `200,000`while `3,000,000` is recommended for liquid staking. 

Any transaction that does not meet both the minimum `Gas Amount` and the minimum `Gas Fee` will not be processed. The minimum `Gas Fee` in Crescent Network is set by each validator, where only transactions including more than the minimum `Gas Fee` will be included in a block proposed by the validator.
