Traders & Freelancers
Organize stablecoin payees, exchange deposit addresses, OTC contacts, and high-frequency destinations.

address confidence
Evidence before action. Not a promise of safety.
ZAFU does not promise a risk-free transfer. It shows address evidence, copy integrity, known warnings, and local trust context before you decide.
Trusted Address Memory
Checks trusted contacts, protected wallets, and transaction-derived history to separate known recipients from unknown or lookalike addresses.
Secure Copy Evidence
Compares the pasted address against recent address-only copy evidence, including Telegram Web when available.
Warning & Review Signals
Shows bundled, community, and external risk signals where available, with conclusions tied to visible evidence.

What ZAFU Is / Is Not
ZAFU gives address evidence and transfer context. It does not replace your wallet, your judgment, or independent counterparty checks.
ZAFU gives you
Trusted address memory
Contacts, protected wallets, labels, and repeat destinations for transfer review.
Evidence at paste time
Source comparison, full-address display, chain context, and public warning signals.
Inspectable extension releases
Public source, release fingerprints, permissions, and privacy boundaries.
ZAFU never does
Custody or signing
ZAFU is not a wallet, signer, transaction broadcaster, or approval layer.
Guarantee risk-free transfers
It shows evidence and limits so you can review, not a promise that every address has no risk.
Run hidden browsing analytics
Protection is scoped to crypto-address workflows and disclosed optional signals.
privacy at a glance
Built to be inspected, not blindly trusted.
A crypto security product has to earn trust with concrete limits. ZAFU keeps the sensitive boundary around keys, signing, browsing, and optional network sharing explicit.
keys
No wallet secrets
ZAFU cannot read private keys, seed phrases, wallet passwords, or signing credentials.
control
No signing
ZAFU cannot approve, initiate, broadcast, or reverse transactions.
analytics
No Advertising Telemetry
Network Mode is optional and shares anonymous aggregate counts only, never addresses or chat text.
audit
Public verification
The extension source and release fingerprints are public so users can inspect what was shipped.
