# Optimizing Gas Fees

## Overview

Gas fee optimization skill that:
- Fetches real-time gas prices from multiple sources
- Estimates transaction costs in ETH and USD
- Analyzes historical patterns to find optimal timing
- Predicts future gas prices
- Compares gas across multiple chains

## Prerequisites

- Python 3.8+ with requests library
- Network access to RPC endpoints
- Optional: `ETHERSCAN_API_KEY` for higher rate limits
- Optional: Custom RPC URLs via environment variables

## Instructions

### 1. Check Current Gas Prices

```bash
cd {baseDir}/scripts && python3 gas_optimizer.py current
```

For specific chain:
```bash
cd {baseDir}/scripts && python3 gas_optimizer.py current --chain polygon
```

### 2. Estimate Transaction Cost

For known operations:
```bash
cd {baseDir}/scripts && python3 gas_optimizer.py estimate --operation uniswap_v2_swap --all-tiers
```

For custom gas limit:
```bash
cd {baseDir}/scripts && python3 gas_optimizer.py estimate --gas-limit 150000 --tier fast
```

Available operations: `eth_transfer`, `erc20_transfer`, `erc20_approve`, `uniswap_v2_swap`, `uniswap_v3_swap`, `sushiswap_swap`, `curve_swap`, `nft_mint`, `nft_transfer`, `opensea_listing`, `aave_deposit`, `aave_withdraw`, `compound_supply`, `compound_borrow`, `bridge_deposit`

### 3. Find Optimal Transaction Window

```bash
cd {baseDir}/scripts && python3 gas_optimizer.py optimal
```

### 4. View Gas Patterns

Hourly patterns:
```bash
cd {baseDir}/scripts && python3 gas_optimizer.py patterns
```

Daily patterns:
```bash
cd {baseDir}/scripts && python3 gas_optimizer.py patterns --daily
```

### 5. Predict Future Gas

```bash
cd {baseDir}/scripts && python3 gas_optimizer.py predict --time 14
```

### 6. Compare Chains

```bash
cd {baseDir}/scripts && python3 gas_optimizer.py compare
```

### 7. View Base Fee History

```bash
cd {baseDir}/scripts && python3 gas_optimizer.py history --blocks 50
```

## Output
