Crypto address protection tools for the moment before you send.
Start with the extension for paste-time protection. Use the web checker when you need a quick address risk lookup without installing anything.
ZAFU Extension
Checks crypto-address pastes on wallet and exchange websites, compares copied vs pasted addresses, catches lookalikes, and never touches keys or seed phrases.
ZAFU Check
Paste an EVM or Solana address to check known threat signals. Best for quick lookups; the extension adds paste-time and personal-history context.
Security model
Review ZAFU permissions, local-first storage, optional Google sync, and the exact data boundary for external threat checks.
Community Signals
See how community-reported, pattern-detected, team-reviewed, confirmed malicious, and disputed address labels are handled.
Teams / Pro beta
