Goerli to Sepolia testnet transition

Linea's principal testnet is now Linea Sepolia. Linea Goerli still exists, but is being phased out and you may encounter performance issues. We advise you use Linea Sepolia for any testnet purposes you require.

We expect to fully deprecate Linea Goerli by the end of May 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:

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.
