uii-links.uno helps you spot fake airdrops, avoid wallet drainers, and lock down your accounts. No hype—just practical security for crypto users.
Step-by-step, copy-paste secure. Perfect for beginners & power users.
Create a layered wallet system, rotate spending keys, and compartmentalize risk without overcomplicating your life.
Learn red flags in transaction prompts, malicious signatures, and fake approvals before you click “Confirm”.
Lock carriers, use app-based 2FA, and create an emergency kit that actually helps if your phone disappears.
Set up allow-lists, anti-phishing codes, and cold storage syncs for “sleep-well” security.
Harden your browser, isolate wallets, and stop trackers without breaking dApps.
Steel plates, Shamir backups, and plausible deniability—without losing the seed yourself.
We track fake airdrops, drainer contracts, and spoofed exchanges.
Drainer site uses wallet-connect modals to request unlimited approvals. Real project has never offered a grants airdrop.
Scammers spoof admins and push remote-control apps. Never share seed/QR; support never asks.
Temporary hijack served a malicious JS bundle. Clear cache, verify signatures, rotate RPC endpoints.
Simple patterns that block 90% of common threats.
Always visit official links, not DMs. Cross-check domain spelling, SSL, and social handles.
Look for unlimited approvals, blind signature requests, or surprise network switches.
Use a fresh wallet for minting/airdrops; keep cold storage offline and separate.
