# Etherscan agent skills for Claude Code, Cursor and RevampKey

> Ready-made Etherscan playbooks for AI agents: check a smart contract's verification and deployment with AI, investigate an Etherscan transaction with AI, review a wallet's activity over a period. Free SKILL.md files for Claude Code, Cursor and Codex, or one click in RevampKey.

## Skills

- [Use Etherscan with AI](https://revampkey.com/marketplace/etherscan/skills/essentials.md): Gives your AI assistant a clear method for querying Etherscan across 50+ EVM chains. It confirms the chain first, narrows queries to a time window, and states what the data can and cannot show.
- [Check a smart contract's verification and deployment with AI](https://revampkey.com/marketplace/etherscan/skills/contract-verification-check.md): Reviews a contract's published source and ABI, its deployer and creation details, and the admin events it emits, then states what verification proves and what it does not. It stays read-only.
- [Investigate an Etherscan transaction with AI](https://revampkey.com/marketplace/etherscan/skills/transaction-investigation.md): Traces one transaction from its hash: confirms the chain and status first, then follows native value, internal calls, token transfers and decoded logs outward. It only reports movements the chain data supports and never takes any on-chain action.
- [Review a wallet's activity over a period](https://revampkey.com/marketplace/etherscan/skills/wallet-activity-review.md): Reviews one Ethereum-style address over a fixed block window, reconciling native and token balances against transfers, internal transactions and gas. It asks you to confirm the chain and window first and reports any gap it cannot explain.

### What is a Etherscan agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each Etherscan skill describes one job, which Etherscan tools to use in which order, what to check first and when to stop and ask you.

### Do the Etherscan skills change anything on their own?

4 of the 4 only read. The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in Etherscan.

### Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect Etherscan; elsewhere you copy the folders into your project or skills directory.

### Do I need the Etherscan MCP server too?

Yes. The skills tell the agent how to do the work; the Etherscan MCP server gives it the tools to do it. The Etherscan MCP setup guide covers every client.
