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
Arbitrum Nova	https://nova.arbitrum.io/rpc	42170	https://nova.arbiscan.io/	Ethereum	Nitro (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 (Rollup)	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.arbiscan.io	Sepolia	Nitro (Rollup)	wss://sepolia-rollup.arbitrum.io/feed	https://sepolia-rollup-sequencer.arbitrum.io/rpc
Stylus Testnet	https://stylus-testnet.arbitrum.io/rpc	23011913	https://stylus-testnet-explorer.arbitrum.io/	Arbitrum Sepolia	Nitro (Rollup)	wss://stylus-sepolia.arbitrum.io/feed	https://stylus-testnet-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. Once Arbitrum Sepolia becomes publicly available, we will phase 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.
