Build a Gas Fee Tracker with AI

Monitor gas fees across Ethereum, Base, Arbitrum, Optimism, and Polygon with historical trends, cost estimates for common operations, and alerts for cheap gas windows. Updated regularly so users always know the best time to transact.

Build Prompt

Copy this prompt into Claude Code

Build a static HTML gas fee tracker dashboard. Dark theme with background #0a0a0f, surfaces #12121a, borders #1a1a2a, accent color #f7931a (Bitcoin orange). Data from inline `const GAS_DATA = [...]`, `const CHAINS = [...]`, `const OPERATIONS = [...]`, `const LAST_UPDATED = "..."`. Each chain has: name, chainId, currentGwei, fastGwei, slowGwei, baseFee, priorityFee, color, avgBlockTime, l1DataFee (for L2s). Operations: Transfer ETH, ERC-20 Transfer, Uniswap Swap, NFT Mint, Contract Deploy — each with gasUnits estimate. Layout: Header with title, chain selector tabs, "Last updated" timestamp. Hero: current gas price for selected chain with slow/standard/fast tiers (color-coded green/yellow/red). Cost estimator table: each operation with gas units × current price = USD cost per tier. 24-hour gas price chart (inline SVG line chart with data points). Multi-chain comparison: side-by-side cards showing current gas + a sample swap cost for each chain. Include "Best Time to Transact" section with historical patterns (weekday/weekend, time of day). Save preferred chain to localStorage. SEO: title, meta description, OG tags. Pre-fill with current approximate gas data. Read the guide at https://accessagent.ai/api/guide and follow it to deploy the site to AccessAgent.ai. My email is [your@email.com].
