How MPC Works
With MPC, the private key is never generated in one place. It is split into 3 independent secret shares during setup. Any 2-of-3 shares can securely sign a transaction.
🔑 Share A (Your Device)
Stored securely in your mobile phone hardware enclave, protected by biometric authorization.
☁️ Share B (FIFA Cloud)
Maintained by FIFA security nodes, enforcing secondary risk and compliance checks.
❄️ Share C (Disaster Backup)
Encrypted and stored in a trusted cold backup system to safely recover your account.
