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 L1 | Tech stack | Sequencer feed URL | Sequencer endpoint⚠️ |
|---|---|---|---|---|---|---|---|
| Arbitrum One | https://arb1.arbitrum.io/rpc | 42161 | https://arbiscan.io/ | Ethereum | Nitro | wss://arb1.arbitrum.io/feed | https://arb1-sequencer.arbitrum.io/rpc |
| Arbitrum Nova | https://nova.arbitrum.io/rpc | 42170 | https://nova.arbiscan.io/ | Ethereum | AnyTrust | wss://nova.arbitrum.io/feed | https://nova-sequencer.arbitrum.io/rpc |
| Arbitrum Goerli (Testnet) | https://goerli-rollup.arbitrum.io/rpc | 421613 | https://goerli.arbiscan.io | Goerli | Nitro | wss://goerli-rollup.arbitrum.io/feed | https://goerli-rollup-sequencer.arbitrum.io/rpc |
| Arbitrum Sepolia (Testnet) | https://sepolia-rollup.arbitrum.io/rpc | 421614 | https://sepolia-explorer.arbitrum.io/ | Sepolia | Nitro | https://sepolia-rollup-sequencer.arbitrum.io/rpc |
⚠️ Unlike https://arb1.arbitrum.io/rpc, the Sequencer endpoint only supports eth_sendRawTransaction and eth_sendRawTransactionConditional calls.
⚠️ Important note: Ethereum Goerli will be deprecated in Q1 2023 but will be supported until Q4 2023. Once Arbitrum Sepolia becomes publicly available, we will phase out the usage of Arbitrum Goerli. The support for Arbitrum Sepolia will cease prior to the conclusion of Goerli Mainnet assistance.

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