MPC Security Technology Explained
What is MPC?
MPC (Multi-Party Computation) is an advanced cryptographic technology. Binance Web3 Wallet splits your private key into three parts:
┌─────────────────────────────────────────────────────┐
│ MPC Three-Party Key Split │
├─────────────────────────────────────────────────────┤
│ 🔑 Key Shard 1: Stored on your device │
│ 🔑 Key Shard 2: Encrypted in your cloud (iCloud/Google) │
│ 🔑 Key Shard 3: Securely held by Binance │
└─────────────────────────────────────────────────────┘
Why is it More Secure?
- No single point of failure: Any single shard being stolen cannot control your assets
- Requires 2/3 shards: At least two shards needed to sign transactions
- No complete private key: Full private key is never generated or reconstructed
- No seed phrase: Avoids risks of seed phrase theft or loss

FAQ
Q: Is Binance Web3 Wallet custodial or non-custodial?
A: Self-custody (non-custodial). Although Binance holds one key shard, they cannot control your assets alone. You need device shard + cloud shard to operate.

A: You can still recover the wallet via device shard + cloud shard. However, it's recommended to periodically transfer important assets to fully self-sovereign wallets.
Q: Which blockchains are supported?
A: Currently supports 60+ blockchains including:
- EVM: Ethereum, BSC, Arbitrum, Optimism, Polygon, etc.
- Non-EVM: Solana, Bitcoin, Tron, etc.
