Interop devnet
The Interop devnet is a temporary public network of two OP Stack Sepolia instances that supports SuperERC20 tokens, native cross-chain messaging, and cross-chain ETH transfers. As we iterate on Superchain interop, these networks will be deprecated once the next devnets are released.

- The "currency symbol" is required by some wallets like MetaMask.
- The
OptimismPortalis a low-level contract responsible for passing messages between L1 and L2. Messages sent directly to theOptimismPortalhave no form of replayability. You can send ether directly to the portal to receive it to the sender address on the L2.
Sending ETH to the interop devnets
Get Sepolia ETH
You can utilize the Superchain Faucet (opens in a new tab) to get ether on Sepolia.
Send the Sepolia ETH to the devnet
You can send ether directly to the OptimismPortal address and it will go to the same sender address on the devnet.
Wait for bridging to complete
It'll take approximately 2 minutes for the bridging process to complete and the ether to appear in your wallet.

- Want to start with local development? Use Supersim, a local dev environment that simulates interop for testing applications against a local version of the Superchain.
- Read about interop message passing to see how you can implement it yourself on this devnet.
