ZAFU Check · Free · No sign-up

Check an address before you send.

Paste any Ethereum or Solana address to check it against real-time threat data and Zafu community signals. For paste-time protection, install ZAFU Extension.

A checker can flag known threats. The extension checks the paste itself.

ZAFU Check cannot see what you copied, your trusted history, or the page you are pasting into. ZAFU Extension adds copied-vs-pasted comparison, personal lookalike detection, and wallet/exchange page context.

Supports Ethereum, Polygon, Arbitrum, Base, Solana, and all EVM-compatible chains

What this checker covers

🔴
GoPlus real-time threats — Checks the address against GoPlus Labs' live threat intelligence database, covering blacklisted addresses, phishing, and sanctioned wallets (EVM only).
🚩
Zafu community signals — Checks whether the address has enough user reports or poisoning-pattern signals to meet the community threshold. Community-reported does not mean team-confirmed. Read the methodology.
⚠️
Limitations — This checker can flag known high-risk addresses, but it cannot see what you copied, your trusted history, or the page you are pasting into. The ZAFU Extension adds that paste-time context.
