  2. 02Wallet network setup guidance
  3. 03RPC and signing security notes

Use cases

  1. 01Connect a wallet to Base mainnet
  2. 02Configure a Base Sepolia test environment

Install

Copy the command and run it in a terminal.

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

  1. Add network with chain ID and RPC from tables above
  2. For testnet, use Sepolia configuration
  3. Bridge ETH from Ethereum or use faucets
