# Get Native Token for Gas

To execute most things on the blockchain network, you will need to pay  gas fee.

Gas fees are payments made by users to compensate for the computational energy required to process and validate transactions on the blockchain. These fees are paid in different token based on the blockchain network and are typically denominated in gwei, where 1 gwei equals 0.000000001 ETH.

The total gas fee for a transaction is determined by two main factors:

1. **Gas Limit**: This represents the maximum amount of computational work the user is authorizing for the transaction.
2. **Gas Price**: This is the amount the user is willing to pay per unit of gas, often measured in gwei.

The total transaction fee is calculated by multiplying the gas limit by the gas price.

Gas fees can fluctuate based on network demand. During periods of high activity, fees tend to increase due to limited network capacity. Conversely, when the network is less congested, gas fees generally decrease. 

Since Nusa support multi-chain features, make sure you have the right token available for gas fee based on the network you are going to use in Nusa.

| Network            | Gas Fee        |
