Arbitrum public RPC endpoints

caution
  • Unlike the RPC Urls, the Sequencer endpoints only support eth_sendRawTransaction and eth_sendRawTransactionConditional calls.
  • Arbitrum public RPCs do not provide Websocket support.
  • View the faucets for testnet Sepolia tokens on L2.

This section provides an overview of the available public RPC endpoints for different Arbitrum chains and necessary details to interact with them.
