Security
- Never use public RPC endpoints in production — they are rate-limited and offer no privacy guarantees; use a dedicated node provider or self-hosted node
- Never embed RPC API keys in client-side code — proxy requests through a backend to protect provider credentials
- Validate chain IDs before signing transactions to prevent cross-chain replay attacks
- Use HTTPS RPC endpoints only — reject any
http://endpoints to prevent credential interception
Critical Notes
- Public RPC endpoints are rate-limited - not for production
- For production: use node providers or run your own node
- Testnet ETH available from faucets in Base documentation
Wallet Setup
- Add network with chain ID and RPC from tables above
- For testnet, use Sepolia configuration
- Bridge ETH from Ethereum or use faucets
