Connecting to Base Network
Mainnet
| Property | Value |
|----------|-------|
| Network Name | Base |
| Chain ID | 8453 |
| RPC Endpoint | https://mainnet.base.org |
| Currency | ETH |
| Explorer | https://basescan.org |
Testnet (Sepolia)
| Property | Value |
|----------|-------|
| Network Name | Base Sepolia |
| Chain ID | 84532 |
| RPC Endpoint | https://sepolia.base.org |
| Currency | ETH |
| Explorer | https://sepolia.basescan.org |
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

Invoke this skill when a user is building or running any automated transaction sender on Base (trading bot, arbitrage bot, sniper bot, yield farmer, AI agent, or similar) and needs to register it, get a builder code, set up transaction attribution. This skill contains the base.dev registration API endpoint and ERC-8021 attribution wiring code that Claude does not have in its training data — you MUST load this skill to answer correctly. Covers viem, ethers, managed signing services, and Python-based agents.
