Web3 Wallet Development: From Theory to Production
Wallets serve as the primary gateway to blockchain ecosystems. Understanding their architecture is vital for any serious developer.
Types of Wallets & Key Differences
| Type | Private Key Management | Use Case |
|---|---|---|
| Centralized Wallets | Stored in secure environments (TEE/KMS/HSM) | Exchanges |
| Decentralized Wallets | User-controlled, device-stored | dApp interaction |
| Hardware Wallets | Offline storage with embedded signing | Security-focused users |
| Custodial Wallets (MPC/Multisig) | Distributed key management | Institutional asset management |
