- Alternative Public Chains: Including EOS, TRON, and others - each with unique characteristics
2. Wallet Type Selection
Different wallet types serve various purposes:
- Light Wallets: Store partial blockchain data, ideal for mobile applications
- Full Node Wallets: Maintain complete blockchain data for maximum security
- Hardware Wallets: Provide highest security through offline private key storage
3. Development Tools and Frameworks
Essential tools for wallet development:
| Tool | Purpose |
|---|---|
| Web3.js | JavaScript library for Ethereum interaction |
| Nethereum | .NET Ethereum client implementation |
| Bitcoin Core | Complete Bitcoin node solution |
