Stylus testnet information
Stylus is currently tagged as a release-candidate. The code has been audited, and testing in production environments is underway. Caution should be taken when used in production scenarios. This documentation is currently in public preview.
To provide feedback, click the Request an update button at the top of this document, join the Arbitrum Discord, or reach out to our team directly by completing this form.
Stylus is undergoing major upgrades, and some improvements are expected to require a chain reset. Prior to a reset, developers on the testnet are recommended to withdraw their testnet ETH (there is no 7-day delay since this is a testnet, withdrawals are processed in minutes) and redeploy their contracts on the new chain. There will be advanced warning of any resets. Stay up-to-date by joining the Stylus channel in Discord.
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 testnet (v1) has been deprecated, but you can still find its information in Stylus testnet information.
- Stylus testnet (v2) has been deprecated, but you can still find its information in Stylus testnet information.
- Visit Quicknode'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 and necessary details to interact with them.
