ViaBTC founder: CoinEx is shutting down, but its hot wallet system is worth copying
- —CoinEx used an MPC-based dual-signature scheme for hot wallets
- —Business and wallet systems were run by independent teams with separate keys
- —Every withdrawal required real-time risk review by both systems
- —Reworking nearly 300 supported chains took more than a year
Why it matters: The CoinEx case shows how hot wallet architecture can prevent losses in a breach, a key issue after the Bitget hack.
