Arbitrum Goerli support ending Mar 18 - migrate to Sepolia

Arbitrum has informed us that they will deprecate Arbitrum Goerli on March 18. On the same day, we will turn off our Goerli nodes for Arbitrum. This means if you try to send requests to these nodes, your requests will fail with a DNS resolution error.

Required actions for developers

To ensure you’re able to continue testing seamlessly, you will need to migrate to Arbitrum Sepolia before March 18.

Arbitrum Sepolia is the sustainable path forward for web3 developers and we encourage devs to use it for any testing and development needs.

Arbitrum Sepolia offers many benefits over Goerli, such as improved scalability and lower gas fees — all attributes we think will ultimately lead to better application development.

How to migrate to Arbitrum Sepolia

Follow these 5 steps to migrate from Goerli to the Sepolia testnet on Arbitrum:

1. Create a new app from the Alchemy dashboard on the Arbitrum Sepolia network.
2. Get free Arbitrum Sepolia tokens from Alchemy's public Arbitrum Sepolia Faucet which drips up to 0.5 SepoliaETH per day.
3. Change your API\_URL to your Arbitrum Sepolia RPC URL: https://arb-sepolia.g.alchemy.com/v2/\[YOUR-API-KEY\]
4. Deploy your test contract to Arbitrum Sepolia.
5. Change your tests to use the new contract.

For more detailed instructions, please reference the "How to Deploy a Smart Contract to the Sepolia Testnet" tutorial on our docs.
