caution
- Unlike the RPC Urls, the Sequencer endpoints only support
eth_sendRawTransactionandeth_sendRawTransactionConditionalcalls. - Arbitrum public RPCs do not provide Websocket support.
- 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.
- Stylus testnet will be deprecated once stylus comes out of beta and is enabled on the Sepolia testnet.
- Visit Quicknode's Sepolia faucet for testnet Sepolia tokens.

More Arbitrum chain RPC endpoints can be found in Chain Connect: Arbitrum One, Arbitrum Nova and Arbitrum Goerli.
Third-party RPC providers
Alternatively, to interact with public Arbitrum chains, you can rely on many of the same popular node providers that you are already using on Ethereum:
