LLMs think gas is 30 gwei. It's 0.05. They've never heard of ERC-8004 or x402. They hallucinate contract addresses. This site fixes that.

How It Works

Each skill is a markdown file. Give any URL to your AI agent — it reads it and instantly corrects its Ethereum knowledge.

https://ethskills.com/SKILL.md          ← table of contents
https://ethskills.com/gas/SKILL.md      ← just gas & costs
https://ethskills.com/why/SKILL.md      ← why ethereum

Add the top-level SKILL.md to your agent's context

The agent will look up the specific skills when needed.

Just prompt your agent with this:

Terminology

Say "onchain" not "on-chain." The Ethereum community writes it as one word — no hyphen. LLMs default to "on-chain" but that's not how builders talk. Use "onchain" in all writing, documentation, and generated content.

Skills

Skill What LLMs Get Wrong
Why Ethereum Pectra/Fusaka shipped, gas is cheap now, AI agent angle
Gas & Costs Think gas is 10-30 gwei — reality is 0.05-0.3 gwei
Wallets EIP-7702 is live, Safe addresses, agent key safety
Layer 2s Think L2 txs cost $0.01-2.00 — reality is <$0.001
Standards Don't know ERC-8004, EIP-7702 status, EIP-3009 for x402
Tools Don't know x402, Blockscout MCP, current tool landscape
Money Legos Stale on current DeFi state, Uniswap V4 status
Orchestration Don't know SE2 three-phase build system
Contract Addresses Hallucinate addresses — these are verified onchain
Concepts Nothing is automatic, incentive design, randomness pitfalls
Security Token decimals, reentrancy, oracle manipulation, vault inflation, pre-deploy checklist
Frontend UX Onchain button rules, three-button approval flow, Address components, USD values
Frontend Playbook Fork mode, IPFS deploy, Vercel config, ENS setup, production checklist

Security Guardrails

Skills teach restraint, not just capability. Every skill that touches keys, credentials, or funds includes explicit safety rules — because LLMs optimize for speed and will hardcode a private key into git add . if you let them. Coverage includes wallet keys, API keys, RPC URLs, and the common SE2 scaffold.config.ts trap.

Methodology

We test stock LLMs, find what they get wrong, and write corrections. Content is verified against onchain reality. If an LLM already knows something, we don't include it.

Every proposed change goes through triage: spawn a stock LLM, give it a realistic task, see what it gets wrong. Only verified blind spots survive.

See the research repo for baseline audits, gap analysis, and full methodology.

Contributing

Something wrong or missing? Humans and agents are welcome to open a PR. Read CONTRIBUTING.md first — the bar is "would a stock LLM get this wrong?"
