Say goodbye to Goerli and hello to Sepolia!

Introducing Sepolia Testnet

We are excited to help lead the transition for the Ethereum ecosystem and the world's best developer tooling from Goerli to the Sepolia testnet, and we remain committed to providing public goods that benefit the community.

Goerli deprecation dates

Goerli support on all networks is ending soon:

• February 16th - Base Goerli
• March 7th - Optimism Goerli
• March 18th - Arbitrum Goerli
• April 1st - Ethereum Goerli
• April 6th - Polygon zkEVM Goerli
• April 11th - Starknet Goerli
• April 13th - Polygon Mumbai

We understand that this may cause some inconvenience for those who have been using Goerli testnet and our Goerli faucet, but we want to assure you that we are providing resources to make the transition as smooth as possible.

Currently supported Sepolia testnets:

Today, we currently support the following Sepolia testnets: 

• Ethereum Sepolia
• Arbitrum Sepolia
• Optimism Sepolia
• Base Sepolia
• Starknet Sepolia
• Polygon Amoy

To start building, get testnet tokens from our supported Sepolia faucets.

Recommended action for developers

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

In our previous announcement on Sepolia, we highlighted Sepolia's benefits, such as improved scalability and lower gas fees — all attributes we think will ultimately lead to better application development.

Our Ethereum Sepolia faucet drips up to 1 SepoliaETH per day and is available to developers as they deploy smart contracts to the Ethereum Sepolia testnet.

Ethereum Sepolia chain information

If you are adding the Sepolia blockchain to your wallet, this is the network information to include:

• Network Name - Sepolia Test Network
• RPC URL - https://eth-sepolia.g.alchemy.com/v2/\[YOUR-API-KEY\]
• Chain ID - 11155111
• Currency Symbol - SepoliaETH
• Block Explorer URL - https://sepolia.etherscan.io/

To start building on Sepolia, sign up for a free Alchemy account, and get free SepoliaETH tokens from Alchemy's public faucet.

Why Sepolia?

The decision to deprecate the Goerli Faucet and move towards Sepolia is to ensure that the Ethereum ecosystem has a viable, stable, and safe path forward to grow.

We are committed to providing the best possible service to the Ethereum developer community and are confident this transition to the Sepolia testnet will help us achieve that goal.

We want to thank the community for their support, and we are excited to continue providing public goods that benefit the community.

If you have any questions or concerns about this transition, visit the Alchemy support center.

We look forward to building the future of web3 with you 🚀
