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 (optionally for a specific chain): 
    cd ${CLAUDE_SKILL_DIR}/scripts && python3 gas_optimizer.py current
cd ${CLAUDE_SKILL_DIR}/scripts && python3 gas_optimizer.py current --chain polygon
  2. Estimate transaction cost for known operations or custom gas limits (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): 
    cd ${CLAUDE_SKILL_DIR}/scripts && python3 gas_optimizer.py estimate --operation uniswap_v2_swap --all-tiers
cd ${CLAUDE_SKILL_DIR}/scripts && python3 gas_optimizer.py estimate --gas-limit 150000 --tier fast  # 150000 = configured value
  3. Find the optimal transaction window with lowest expected gas: 
    cd ${CLAUDE_SKILL_DIR}/scripts && python3 gas_optimizer.py optimal
  4. View gas patterns (hourly or daily): 
    cd ${CLAUDE_SKILL_DIR}/scripts && python3 gas_optimizer.py patterns
cd ${CLAUDE_SKILL_DIR}/scripts && python3 gas_optimizer.py patterns --daily
  5. Predict future gas prices for a given hour: 
    cd ${CLAUDE_SKILL_DIR}/scripts && python3 gas_optimizer.py predict --time 14
  6. Compare gas prices across multiple chains: 
    cd ${CLAUDE_SKILL_DIR}/scripts && python3 gas_optimizer.py compare
  7. View base fee history for recent blocks: 
    cd ${CLAUDE_SKILL_DIR}/scripts && python3 gas_optimizer.py history --blocks 50

Output

  • Current: Base fee, priority fee, and tier prices (slow/standard/fast/instant)
  • Estimate: Gas cost in native token and USD for each tier
  • Patterns: Historical hourly/daily patterns with low-gas markers
  • Optimal: Recommended transaction window with expected savings
  • Predict: Gas forecast for specific time with confidence
  • Compare: Side-by-side gas prices across chains

Supported Chains

| Chain | Native Token | Block Time | |-------|--------------|------------| | Ethereum | ETH | ~12 sec | | Polygon | MATIC | ~2 sec | | Arbitrum | ETH | ~0.25 sec | | Optimism | ETH | ~2 sec | | Base | ETH | ~2 sec |

Price Tiers

| Tier | Percentile | Confirmation Time | |------|------------|-------------------| | Slow | 10th | 10+ blocks (~2+ min) | | Standard | 50th | 3-5 blocks (~1 min) | | Fast | 75th | 1-2 blocks (~30 sec) | | Instant | 90th | Next block (~12 sec) |
