Crypto Wallet Security Audit

Your wallet has unlimited token approvals you forgot about, stale permissions to contracts you no longer use, and maybe interactions with flagged addresses you never noticed. One exploit and everything is gone.

This skill runs a comprehensive security audit on any EVM wallet across Ethereum, Base, Polygon, Arbitrum, and Optimism. It checks:

• Token Approval Audit — finds every active approval, flags unlimited and stale ones, identifies unverified spenders, and generates revocation commands • NFT Approval Audit — catches dangerous setApprovalForAll permissions to non-marketplace contracts • Transaction Pattern Analysis — reviews recent activity for drainer patterns, dust attacks, address poisoning, and interactions with suspicious contracts • Known Scam Contract Check — cross-references your transaction history against unverified and recently-deployed contracts • Key Management Scoring — 10-category weighted assessment of your operational security practices (key storage, backup, isolation, phishing defense, multi-sig, simulation, monitoring)

Produces a scored report (0-100) with prioritized action items: what to revoke immediately, what to fix this week, and ongoing hardening practices.

Includes working shell commands using Etherscan/Basescan APIs and Foundry cast for revocation. All analysis uses public on-chain data — never requests private keys or seed phrases.

Every crypto user should audit their wallet at least monthly. Most never do. This skill makes it systematic and repeatable.
