SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Outdated assumptions about Ethereum gas fees lead to wildly inflated cost estimates and poor decisions about where to deploy or transact. This Skill provides current, verified gas price data and real transaction cost breakdowns so you can answer cost questions accurately. ## Core Features & Use Cases - Live Gas Verification: Check current base fees with cast base-fee against public RPC endpoints instead of relying on stale training data. - Cost Reference Tables: Look up realistic costs for ETH transfers, ERC-20 operations, swaps, NFT mints, and contract deployments on mainnet and L2s like Arbitrum, Base, zkSync, and Scroll. - Mainnet vs L2 Guidance: Get concrete criteria for choosing between mainnet and L2s based on transaction type, frequency, and user experience needs. - Use Case: A user asks whether deploying an ERC-20 token on Ethereum is affordable. Instead of quoting 2021-era prices of $200-500, you verify the live base fee and report the actual cost of roughly $0.50. ## Quick Start Ask the AI to estimate the current cost of deploying an ERC-20 contract on Ethereum mainnet versus Base using live gas data.

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 cost roughly $0.004 and an ERC-20 transfer about $0.013 at ETH prices near $2,000. Verify current conditions with `cast base-fee --rpc-url https://eth.llamarpc.com` since fees fluctuate.

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 it is now cheap enough for most apps. Choose an L2 for consumer apps, gaming, micro-payments, and high-frequency transactions where sub-cent fees and faster blocks matter.

Why did Ethereum gas fees drop so much compared to 2021?▼

Four changes drove fees down over 95%: EIP-4844 introduced cheap blob transactions for L2 data, activity migrated to L2s, Pectra doubled blob capacity, and Fusaka added PeerDAS plus doubled the gas limit to 60M.

What maxFeePerGas and priority fee should I set for Ethereum transactions?▼

Set maxFeePerGas to 1-2 gwei for headroom against spikes and maxPriorityFeePerGas to 0.01-0.1 gwei for quick inclusion. If the base fee exceeds 5 gwei, a spike is occurring and waiting is usually worthwhile.
