# GasPass

GasPass is a feature that allows you to make transactions without worrying about gas fees by using coupons. By registering various coupons (vouchers) in the **“GasPass”** menu, the gas fees for transfers or swaps are automatically paid to the blockchain using your available coupons.

**GasPass currently supports the following networks:**

* Ethereum (ERC20)
* Base (BASE-ERC20)
* Solana (SPL-Token)
