• Viem: A new TypeScript-native library replacing ethers.js, developed by the Wagmi team.

How MetaMask Secures Wallet Keys

Keyring Architecture

MetaMask uses a KeyringController to manage encrypted wallet secrets:

1. Encrypted Storage: Secrets are encrypted via user passwords and stored in chrome.storage.local.
2. In-Memory Decryption: Decrypted keys reside in memory (memStore) temporarily after unlock.

Encryption Mechanism

• Browser-Passworder: PBKDF2 (10,000 iterations) and AES-GCM encrypt secrets.
• Mobile App: Uses React Native’s AsyncStorage with PBKDF2 (5,000 iterations) and AES-CBC.

Mobile Security Features

• Biometric Unlock: Passwords stored securely via react-native-keychain.
• Hardware Backing: iOS Keychain and Android Keystore protect sensitive data.

FAQs

1. How does MetaMask prevent key theft?

MetaMask encrypts keys with user passwords and never stores decrypted secrets persistently.

2. Is browser storage safe for wallet keys?

Yes, keys are encrypted via robust algorithms (PBKDF2 + AES) before storage.

3. What makes Viem better than ethers.js?

Viem offers a leaner, TypeScript-first API with better modularity and performance.
