​
Guardian System

Guardians are trusted contacts who help secure your Social Vault through multi-signature approval.

​
Requirements

Your Social Vault requires exactly 5 Guardians:
  • Each Guardian must have an active usmewe account
  • Guardians must accept their role
  • 3 of 5 approvals required for any withdrawal
Choose Guardians you trust completely. They cannot access your funds, but they can block withdrawals.

​
Guardian Responsibilities

Review and approve legitimate withdrawal requests

Block Suspicious Activity

Flag or cancel suspicious withdrawal attempts

Emergency Response

Account Recovery

​
Removing Guardians

Guardian removal has a 7-day cooling period: 
Day 0: Initiate removal
Day 1-7: Cooling period (all Guardians notified)
Day 7: Guardian removed if not cancelled
This delay prevents an attacker from quickly removing all Guardians before stealing funds.

​
