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

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

For specific chain:

cd {baseDir}/scripts && python3 gas_optimizer.py current --chain polygon

2. Estimate Transaction Cost

For known operations:

cd {baseDir}/scripts && python3 gas_optimizer.py estimate --operation uniswap_v2_swap --all-tiers

For custom gas limit:

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

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

4. View Gas Patterns

Hourly patterns:

cd {baseDir}/scripts && python3 gas_optimizer.py patterns

Daily patterns:

cd {baseDir}/scripts && python3 gas_optimizer.py patterns --daily

5. Predict Future Gas

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

6. Compare Chains

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

7. View Base Fee History

cd {baseDir}/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)

Error Handling

See {baseDir}/references/errors.md for:

RPC connection issues
API rate limiting
Price feed errors
Pattern analysis errors

evaluating-machine-learning-models: This skill allows Claude to evaluate machine learning models using a comprehensive suite of metrics. It should be used when the user requests model performance analysis, validation, or testing. Claude can use this skill to assess model accuracy, precision, recall, F1-score, and other relevant metrics. Trigger this skill when the user mentions "evaluate model", "model performance", "testing metrics", "validation results", or requests a comprehensive "model evaluation".

It should be used when the user requests the creation of a new neural network, modification of an existing one, or assistance with defining the layers, parameters, and training process. The skill is triggered by requests involving terms like "build a neural network," "define network architecture," "configure layers," or specific mentions of neural network types (e.g., "CNN," "RNN," "transformer").
