Goerli to Sepolia testnet transition

Linea's principal testnet is now Linea Sepolia. We advise you use Linea Sepolia for any testnet purposes.

L1 Goerli is in a deprecated state. Finalization and bridging between Linea Goerli (L2) and Goerli (L1) will therefore not be available. Linea Goerli will otherwise continue to operate as normal.

We will officially decommission Linea Goerli on May 31 2024.

Running a Sepolia node

If you run a Linea Goerli testnet node, we recommend you transition to running a Linea Sepolia node as soon as possible.

You will need to spin up a new node. The method is the same as before, and as detailed in our guide. However, you must use new genesis files specific to Linea Sepolia:

Here are the bootnodes you should use when initiating your client:


Updating your dapps

For your dapp to remain functional, you must:

  • Deploy any smart contracts anew on Linea Sepolia
  • Ensure your dapps reference the new smart contract deployments.
