Gas Fee Optimizer

Optimize Ethereum transaction gas fees through strategic timing, routing alternatives, and Layer 2 solutions.

Installation

/plugin install gas-fee-optimizer@claude-code-plugins-plus

Usage

Optimize Gas Command

/optimize-gas

Or use the shortcut:

/gas

Example Queries

# Check current gas prices
/gas What's the current gas price on Ethereum?

# Timing optimization
/gas Should I mint this NFT now or wait for lower gas?

# Compare networks
/gas Compare gas costs: Ethereum mainnet vs Arbitrum vs Polygon

# Transaction-specific advice
/gas I need to swap 1 ETH for USDC - what's the best strategy?

# Historical analysis
/gas When is the best time of day to make transactions?

Features

• Real-Time Gas Analysis - Current base fee and priority recommendations
• Historical Context - Compare to 24h and 7-day averages
• Timing Optimization - Best time windows for low-fee transactions
• L2 Comparisons - Gas costs across Arbitrum, Optimism, Base, zkSync
• Sidechain Options - Polygon, Gnosis Chain alternatives
• Cost Estimates - Transaction-specific cost calculations
• Strategic Recommendations - Wait vs execute now analysis

What It Analyzes

1. Current Network State - Base fee, congestion level
2. Historical Patterns - Typical low-fee periods
3. Transaction Type - Gas estimates for different operations
4. Alternative Routes - L2 and sidechain comparison
5. Urgency Factor - Time-sensitive vs routine transactions
6. Cost-Benefit - Savings from waiting vs opportunity cost

Output Includes

• Current gas price breakdown (base + priority fee)
• Estimated costs for common transaction types
• Historical comparison (percentile ranking)
• Best time windows for transactions
• L2/sidechain cost comparison table
• Specific optimization strategies
• Wait vs execute recommendation

Transaction Types Covered

• Simple Transfers - ETH sends (~21,000 gas)
• Token Transfers - ERC-20 operations (~65,000 gas)
• DEX Swaps - Uniswap, SushiSwap (~150,000 gas)
• NFT Mints - Collection minting (~200,000 gas)
• DeFi Operations - Lending, staking, yield farming (varies)

Layer 2 Networks Compared

• Arbitrum - Optimistic rollup, high liquidity
• Optimism - Optimistic rollup, EVM-equivalent
• Base - Coinbase L2, fast finality
• zkSync - Zero-knowledge rollup, high security
• Polygon - Sidechain, lowest cost
• Gnosis Chain - xDai sidechain

Optimization Strategies

Timing

• Identify low-congestion time windows
• Historical pattern analysis
• Weekend vs weekday comparison

Routing

• L2 migration for frequent users
• Sidechain alternatives for specific use cases
• Bridge cost calculations

Technical

• Batch transaction recommendations
• Gas-efficient contract interactions
• Approval optimization

Important Notes

• Gas prices are highly volatile and unpredictable
• Historical patterns don't guarantee future prices
• Consider transaction urgency and value
• Bridge costs may negate L2 savings for one-time transactions
• Opportunity cost of waiting may exceed gas savings
• This is optimization guidance, not financial advice

Requirements

• Transaction type or operation description
• (Optional) Urgency level
• (Optional) Transaction value for cost-benefit analysis
