Traditional MPC wallets assume key shares stay safe forever. Phoenix Chain automatically refreshes shares with hardware-backed entropy. Even if shares are stolen, future operations remain secure.
Hardware root of trust → TEE isolation → encrypted storage → epoch key rotation → PCS injection → Merkle commitment → quarantine enforcement. Defense at every level.
Compromised key shares are automatically detected, quarantined, and replaced. No manual intervention. No downtime. System heals itself.
