Arbitrum public RPC endpoints
- Unlike the RPC Urls, the Sequencer endpoints only support
eth_sendRawTransactionandeth_sendRawTransactionConditionalcalls. - Arbitrum public RPCs do not provide Websocket support.
- Stylus testnets v1 and v2 have been spun down and are not accesible anymore.
- Visit Quicknode's Arbitrum Sepolia faucet or Alchemy's Arbitrum sepolia faucet for testnet Sepolia tokens on L2.
This section provides an overview of the available public RPC endpoints for different Arbitrum chains that have Stylus enabled, and necessary details to interact with them.
