Onchain Claim Verifier — Agent Skill (SKILL.md)

Turn "trust me" into "verified on-chain".

A drop-in agent skill (SKILL.md) that teaches your AI agent to verify crypto claims against live blockchain data — using public RPC endpoints, no API keys, no paid providers.

WHAT IT CHECKS

• Did a transaction actually settle? (receipt parsing, not screenshots)

• Did the money arrive? (ERC-20 Transfer decode, block-pinned reads)

• What is the real balance at a point in time? (historical eth_call)

• Is a wallet compromised? (EIP-7702 delegation, approvals, allowances)

• Is a token real? (pool existence, honeypot checks)

INSTALL

Save SKILL.md into your agent's skills folder:

• Claude Code: ~/.claude/skills/onchain-claim-verifier/SKILL.md

• Cursor: ~/.cursor/skills/onchain-claim-verifier/SKILL.md

• OpenClaw: your skills folder

• Other agents: paste the body into your system prompt

WHAT'S INSIDE

• SKILL.md — the full skill (procedures, golden rules, output format)

• README.md — install guide + example prompts

No dependencies. No API keys. Public RPC only.
