🔒 Security Verification

Critical: Always verify network addresses and names through official channels:

1. Check this repository - All names listed here are official
2. Verify on naming service - Use official apps (app.ens.domains, space.id, etc.)
3. Cross-reference - Confirm with ADDRESSES.md
4. Official channels - Verify via t.me/ucash or security@u.cash

Never trust names or addresses from:

• Unsolicited DMs
• Unverified social media
• Fake websites (ucash.eth.com, ucash.io, etc.)
• Unknown sources
