Arbitrum public RPC endpoints
This section provides an overview of the available public RPC endpoints for different Arbitrum chains and necessary details to interact with them.
| Name | RPC Url(s) | Chain ID | Block explorer | Underlying chain | Tech stack | Sequencer feed URL | Sequencer endpoint⚠️ |
|---|---|---|---|---|---|---|---|
| Arbitrum One | https://arb1.arbitrum.io/rpc | 42161 | https://arbiscan.io/ | Ethereum | Nitro (Rollup) | wss://arb1.arbitrum.io/feed | https://arb1-sequencer.arbitrum.io/rpc |

⚠️ Unlike the RPC Urls, the Sequencer endpoints only support eth_sendRawTransaction and eth_sendRawTransactionConditional calls.
⚠️ Important note: Arbitrum public RPCs do not provide Websocket support.
⚠️ Important note: Ethereum Goerli was deprecated in Q1 2023 but will be supported until Q1 2024. We are currently phasing out the usage of Arbitrum Goerli. Support for Arbitrum Goerli will cease prior to the conclusion of Ethereum Goerli.
⚠️ Important note: Stylus testnet will be deprecated once stylus comes out of beta and is enabled on the Sepolia testnet.

More Arbitrum chain RPC endpoints can be found in Chain Connect: Arbitrum One, Arbitrum Nova and Arbitrum Goerli.
