Skill 12 Gas Optimization

Optimizes transaction gas via EIP-1559 fee prediction, nonce management, private transaction submission, and EIP-4844 blob fee handling. Use when estimating fees, fixing stuck transactions, or submitting MEV-sensitive txs.

Gas Optimization

When to Use

Estimating transaction costs before execution
Managing nonces for sequential or parallel txs
Submitting private transactions (Flashbots, MEV-Share)
Handling EIP-4844 blob transactions (L2 data availability)
Recovering stuck transactions (speed up / cancel)

Prerequisites

MCP: blockchain-rpc-server
Skill-15 for private tx routing on mainnet swaps

EIP-1559 Fee Strategy

maxPriorityFeePerGas = baseFee * 0.1 (min 1 gwei on Ethereum)
maxFeePerGas = baseFee * 2 + maxPriorityFeePerGas

Fetch eth_feeHistory for last 10 blocks
Use 75th percentile of priority fees
On L2s (Arbitrum, Base, Optimism): use L1 data fee + L2 execution fee

Nonce Management

Query eth_getTransactionCount with pending tag
Use nonce manager for parallel txs (increment locally, track pending)
Cancel: send 0 ETH self-transfer with same nonce, +20% gas
Speed up: resubmit with same nonce, +15% maxFeePerGas

Private Transactions

Network	Method
Ethereum	Flashbots Protect RPC, MEV-Share
Polygon	Fastlane private RPC
Base/Arbitrum	Sequencer private orderflow (limited)

Use private submission for swaps, liquidations, and any MEV-exposed operation.

Blob Fees (EIP-4844)

For rollup batch submissions or blob-carrying txs:

blobGasPrice = getBlobBaseFee()
totalBlobCost = blobGasUsed * blobGasPrice

Monitor excessBlobGas in block header for fee spikes.

L2 Gas Notes

Chain	Gas Token	Notes
Arbitrum	ETH	L1 calldata cost dominates
Optimism	ETH	L1 fee + L2 fee split
Base	ETH	OP Stack, similar to Optimism
Polygon	POL	Low base fees, occasional spikes
