What Is a #GasFee in Crypto?

If you’ve ever sent crypto or swapped tokens, you’ve probably come across something called a “Gas Fee.” But what exactly is it?

A gas fee is a small amount you pay to the blockchain network to process your transaction.

It’s like a service charge for keeping things moving.

For example:

On Ethereum, gas fees can be high depending on network activity.

On BNB Chain or Solana, they’re much lower.

Some chains like Polygon offer super cheap fees.
