Scan your wallet security posture

Enter a public wallet address if you want format validation, then answer the security questions below. This tool stays in your browser and does not need wallet access.
Public addresses are okay. Never paste a seed phrase, private key, or secret recovery phrase.
This scanner is designed for wallet hygiene and personal safety review. It does not replace a full on-chain security audit, transaction simulation engine, or professional incident response.

How this wallet security scanner works

This tool helps you review the most common weaknesses in wallet safety: recovery phrase handling, allowance management, device hygiene, phishing habits, blind signing, and wallet separation. It also validates common public address formats for EVM wallets, Bitcoin, and Solana.

Because this version is designed for speed, privacy, and broad compatibility, it does not require wallet connection and does not pull blockchain data. That makes it lightweight, fast, and easy to use on both desktop and mobile.

  • Validate public wallet formatting for common chains
  • Spot high-risk behavior before it becomes a costly mistake
  • Improve DeFi, NFT, and trading wallet hygiene

Best practices for crypto wallet security

Good wallet security is not just about using the right app. It is about habits. The strongest crypto users separate wallets by purpose, review approvals, avoid random links, verify domains, and never expose recovery phrases online.

  • Use a hardware wallet for meaningful balances
  • Keep a separate burner wallet for testing new dApps
  • Revoke unused token approvals regularly
  • Never trust surprise NFTs, airdrops, or fake support messages
  • Read transaction prompts carefully before signing
  • Store recovery phrases offline, not in cloud tools or screenshots

Frequently asked questions

What does this crypto wallet security scanner actually scan?

It scans your wallet security posture based on the information you provide, including wallet habits, recovery phrase handling, hardware wallet usage, approval hygiene, and public address formatting. It does not drain-check your wallet or fetch blockchain data in this version.

Does this tool connect to MetaMask, Phantom, or other wallets?

No. This version is fully browser-based and does not require a wallet connection. That keeps it fast and privacy-friendly.

Can this detect malicious token approvals automatically?

Not automatically in this standalone version. A full approval scanner would need chain-specific RPC calls or third-party APIs to inspect current allowances and contracts.

Is it safe to paste my wallet address here?

A public wallet address is generally safe to paste into tools like this. Never enter your seed phrase, private key, recovery phrase, or any secret credentials.

Who should use this tool?

It is useful for beginners, traders, NFT users, DeFi users, and anyone who wants a quick security review before interacting with apps, bridges, swaps, or token approvals.
