SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Outdated training data leads to wildly inflated Ethereum gas estimates (often 100-600x too high), causing poor cost decisions when estimating transaction fees, choosing between mainnet and L2s, or answering questions about Ethereum being expensive. ## Core Features & Use Cases - Accurate Cost Tables: Provides order-of-magnitude costs for common actions (ETH transfers, ERC-20 transfers, swaps, NFT mints, contract deploys) at various gas price levels. - Mainnet vs L2 Comparison: Compares fees across Ethereum mainnet, Arbitrum, Base, zkSync, and Scroll, with guidance on when to use each. - Live Verification Commands: Supplies cast base-fee and cast gas-price commands plus fee-setting rules of thumb for EIP-1559 transactions. - Use Case: A user asks how much it costs to deploy an ERC-20 token. Instead of quoting outdated 2021 figures, you reference current post-Fusaka conditions (~$0.24 at 0.1 gwei) and verify with a live RPC call. ## Quick Start Ask the AI to estimate the current cost of deploying an ERC-20 contract on Ethereum mainnet and verify the live base fee.

Frequently Asked Questions about gas

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How much does an Ethereum transaction cost right now?▼

Post-Fusaka, typical base fees are under 1 gwei, making an ETH transfer about $0.004 and an ERC-20 transfer about $0.013 at 0.1 gwei. Verify current conditions with `cast base-fee --rpc-url https://eth.llamarpc.com` since gas fluctuates.

How do I check current Ethereum gas prices from the command line?▼

Use Foundry's cast tool: run `cast base-fee --rpc-url https://eth.llamarpc.com` for the current base fee or `cast gas-price` for the gas price. You can also check trackers like etherscan.io/gastracker or ultrasound.money.

Should I deploy on Ethereum mainnet or an L2 like Arbitrum or Base?▼

Use mainnet for DeFi, governance, high-value transfers, and composing with mainnet liquidity, since mainnet is now cheap enough for most apps. Use L2s for consumer apps, gaming, micro-payments, and high-frequency transactions where sub-cent fees and fast blocks matter.

Why did Ethereum gas fees drop so much after 2024?▼

Fees dropped over 95% due to EIP-4844 blobs (Dencun, March 2024), activity migrating to L2s, Pectra doubling blob capacity (May 2025), and Fusaka adding PeerDAS plus a doubled gas limit (December 2025).

What maxFeePerGas and maxPriorityFeePerGas should I set?▼

Under current conditions, set maxFeePerGas to 1-2 gwei for spike headroom and maxPriorityFeePerGas to 0.01-0.1 gwei for quick inclusion. Spikes above 5 gwei happen during major events but typically last only minutes to hours.
