The wallet is the gateway to Web3. Modern crypto wallets must balance security with usability — supporting multiple chains, enabling gasless transactions, and providing social recovery options that don't compromise self-custody.
Wallet Architecture Options
- HD Wallets: BIP-39/44 hierarchical deterministic wallets with seed phrase backup.
- MPC Wallets: Multi-Party Computation splits keys across devices — no single point of failure.
- Smart Contract Wallets: Account abstraction (ERC-4337) enables gasless transactions and social recovery.
