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
