Why is an 'unlimited' approval considered a risk?

Unlimited approvals allow a smart contract to spend any amount of a specific token in your wallet. If that contract is malicious or later exploited, your entire balance of that token could be drained.

Does this skill execute transactions or revoke approvals?

No, this is a read-only analysis tool. It identifies risks and generates a list of suggested revocations, but it does not manage private keys or execute blockchain transactions.

Which blockchains are supported by the auditor?

The skill supports Ethereum, Binance Smart Chain (BSC), Polygon, Arbitrum, Optimism, and Base.

Do I need an API key to use this skill?

The tool works with public RPCs, but adding an ETHERSCAN_API_KEY environment variable is recommended to avoid rate limiting during comprehensive scans.

How does the security score work?

The score (0-100) is a weighted average based on four factors: active approvals (40%), contract interactions (30%), transaction patterns (20%), and wallet maturity (10%).

Audits cryptocurrency wallet security by analyzing token approvals, permissions, and transaction patterns to identify risk exposure.

The Wallet Security Auditor skill provides a comprehensive security analysis toolkit for EVM-compatible cryptocurrency wallets, allowing Claude to scan for risky ERC20 token approvals, analyze suspicious transaction patterns, and calculate weighted security scores. It supports multiple chains including Ethereum, BSC, and Polygon, generating actionable reports and prioritized revoke lists to help users safeguard their assets against unauthorized access and malicious contracts. Designed as a read-only tool, it focuses on identifying vulnerabilities like unlimited approvals to unverified contracts and stale permissions without ever requiring or touching private keys.
