Ethereum Goerli Support Ending April 1st - Migrate to Sepolia

We will turn off our Goerli nodes for Ethereum on April 1, 2024. (Note: this is an updated date from Alchemy's original deprecation date of April 3, 2024.) This means if you try to send requests to these nodes, your requests will fail with a DNS resolution error.

Per Ethereum’s original plans, the Goerli testnet was due to be sunset on April 13th. However, nearly all Goerli validators are currently shut down.

This means the Ethereum Goerli network will not function reliably until April 13th. We are already seeing extreme instability in the network, and we urge you to migrate to Sepolia immediately.

Required Actions for Developers

To ensure you’re able to continue testing seamlessly, you will need to migrate to Ethereum Sepolia before April 1st.

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

Ethereum 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 Ethereum Sepolia

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

1. Create a new app from the Alchemy dashboard on the Etherum Sepolia network.

2. Get free Optimism Sepolia tokens from Alchemy's public Ethereum Sepolia Faucet which drips up to 0.5 SepoliaETH per day.

3. Change your API_URL to your Optimism Sepolia RPC URL: https://eth-sepolia.g.alchemy.com/v2/[YOUR-API-KEY]

4. Deploy your test contract to Ethereum 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.
