# Understanding Gas Fees

> Learn about blockchain transaction costs and how to optimize them

# Understanding Gas Fees

Gas fees are transaction costs paid to process operations on blockchain networks. Understanding them helps you save money and avoid failed transactions.

## What Are Gas Fees?

Think of gas like the processing fee for blockchain transactions:

* Required for all blockchain operations
* Paid in the network's native token
* Varies based on network congestion
* Different for each type of action

## Gas on Different Networks

### Base Network (Recommended)

TokenFabric recommends Base for most users:

* Lower gas costs (\$0.01-0.05 per transaction)
* Fast processing
* Ethereum security
* Optimized for TokenFabric

### Ethereum Mainnet

* Higher security
* More expensive (\$2-100+ per transaction)
* Better for high-value transactions
* Wider adoption

<Tip>
  Start with Base Network if you're new. It offers the best balance of cost and functionality for most users.
</Tip>

## Understanding Gas Costs

### Common Operations

Approximate costs on Base Network:

1. **Basic Transfers**
   * Send tokens: \$0.01-0.05
   * Approve contracts: \$0.02-0.10
   * Cancel transactions: \$0.01-0.03

2. **Token Operations**
   * Create token: \$0.10-0.50
   * Swap tokens: \$0.05-0.20
   * Bridge assets: \$0.10-0.30

<Note>
  Costs are estimates and can vary based on network conditions.
</Note>

## Optimizing Gas Costs

### Best Practices

1. **Timing**
   * Check network congestion
   * Use during quiet periods
   * Monitor gas trends
   * Batch transactions when possible

2. **Settings**
   * Understand priority levels
   * Set appropriate limits
   * Consider transaction speed
   * Use gas estimation tools

## Common Gas Issues

### Failed Transactions

Common causes and solutions:

1. **Insufficient Gas**
   * Set higher gas limit
   * Ensure enough network tokens
   * Check current gas prices
   * Use gas estimators

2. **Network Congestion**
   * Wait for lower fees
   * Adjust priority
   * Consider other networks
   * Batch transactions

<Warning>
  Failed transactions still cost gas fees. Always ensure proper settings to avoid wasting funds.
</Warning>
