# Connect to Base

> Network details for Base Mainnet and Base Sepolia: RPC endpoints, chain IDs, and block explorers.

Base is a standard EVM chain, so any Ethereum tool, wallet, or library works unchanged. Just point it at the network details below.

## Network Details

| | Base Mainnet | Base Sepolia (testnet) |
| - | - | - |
| RPC endpoint | `https://mainnet.base.org` | `https://sepolia.base.org` |
| Transaction submission | `https://mainnet-sequencer.base.org` | `https://sepolia-sequencer.base.org` |
| Chain ID | `8453` | `84532` |
| Currency | ETH | ETH |
| Block explorer | [basescan.org](https://basescan.org) | [sepolia.basescan.org](https://sepolia.basescan.org) |

<Note>
  Use the transaction submission endpoint only to send transactions. Use the RPC endpoint for all other requests.
</Note>

<Warning>
  The public RPC endpoints are free, rate limited, and best effort, and are not suitable for production apps. Since October 8, 2026, `https://mainnet.base.org` no longer serves the `debug`, `trace`, or `txpool` namespaces, and read requests have a lower rate limit. If your app uses these namespaces or needs higher throughput, use a dedicated RPC provider from the [Builder Stack](/get-started/builder-stack).
</Warning>
