# Understanding Network & Other Fees

## What is the network fee (gas)?

Sending transactions on blockchain networks requires a small amount of the blockchains native currency (Base's native currency is ETH and Polygon's is POL) much like your credit card or bank sometimes has a processing fee. 

This network fee is called "gas" and it is the live cost for your transaction to be processed efficiently on-chain. This fee is dictated by the current demand that the network is experiencing to process the queue of transactions made by all of it's participants.

## What if I don't have enough to pay for gas?

If you do not have enough of a blockchains native currency to pay for a transaction, you will not be able to proceed and will first need to [fund your wallet](/wallet/getting-started/funding-your-wallet.md) with more of the blockchains native currency.

## Transactions Requiring Gas

The following transactions require a small amount of a networks native currency to be processed on-chain:

* Sending funds
* Sending Splits
* Sending NFT collectibles
* Buying NFT collectibles
* Listing NFT collectibles for sale
* 3rd-party interactions with DeFi platforms (such as staking or swapping funds)

Majority of transactions on **Base** or **Polygon** do not exceed $0.01 worth of native currency, as they are both highly scalable blockchain layer-2 networks.
