#CryptoFees101 The **gas fees** in crypto are the costs associated with transactions on a blockchain. They serve to compensate the miners or validators who process and secure the operations.

### 🔍 **How do gas fees work?**

- **Unit of measurement**: Gas is measured in **Gwei**, a fraction of Ethereum (ETH).

- **Base fee**: Minimum amount required to include a transaction in a block.

- **Priority fee**: An optional tip to speed up the processing of the transaction.

- **Gas limit**: Maximum amount of gas a user is willing to pay.

### ⚡ **Why do fees vary?**

- **Network congestion**: The more transactions there are, the higher the fees.

- **Complexity of the transaction**: Smart contracts require more gas.

- **Protocol updates**: Ethereum introduced EIP-1559 to better manage fees

### 🛠 **Optimize gas fees**
