NOTE: The current Interop devnet has been deprecated. This page will be updated once the next Interop devnet is live.

💡

Superchain interop devnet is currently in active development and may experience periods of instability, including potential outages, as the networks are regularly updated and improved. Developers should expect some level of unreliability when interacting with the devnet. The devnet is intended for testing and development purposes only, and should not be relied upon for mission-critical applications.

The Superchain interop devnet is a temporary public network of two OP Stack Sepolia instances that support Superchain interop enabling native ETH and SuperchainERC20 cross-chain token transfers. As we iterate on Superchain interop, these networks will be deprecated once the next devnets are released.

  1. The "currency symbol" is required by some wallets like MetaMask.
  2. The OptimismPortal is a low-level contract responsible for passing messages between L1 and L2. You can send ETH directly to the portal to receive it to the sender address on the L2.

Getting testnet ETH on the interop devnet

Get testnet ETH from the Superchain Faucet

You can utilize the Superchain Faucet (opens in a new tab) to get ETH.

Bridging ETH to the interop devnet

Get Sepolia ETH from the Superchain Faucet

You can utilize the Superchain Faucet (opens in a new tab) to get ETH on Sepolia.

Send the Sepolia ETH to the devnet

You can send ETH directly to the OptimismPortal address and it will go to the same sender address on the devnet. Alternatively, you can use this bridge front end (opens in a new tab) to bridge ETH from Sepolia.

Wait for bridging to complete

It'll take approximately 2 minutes for the bridging process from Sepolia to L2 to complete and the ETH to appear in your wallet.
