Gas & Costs on Ethereum

What You Probably Got Wrong

Your gas estimate is 100-600x too high. Most LLMs confidently state gas is 10-30 gwei. Post-Fusaka (Dec 2025), typical base fee is under 1 gwei — usually 0.1-0.5 gwei. Verify: cast base-fee --rpc-url https://eth.llamarpc.com

• Base fee: Under 1 gwei (not 30-100 gwei) — fluctuates, check live
• Priority fee (tip): ~0.01-0.1 gwei
• ETH price: ~$2,000 (not $2,500-3,000) — volatile, always check a Chainlink feed or CoinGecko

What Things Actually Cost (Early 2026)

Costs calculated at ETH ~$2,000. Gas fluctuates — use cast base-fee for current. These are order-of-magnitude guides, not exact quotes.
