Discover and build net-new use cases with Superchain Interop

There is so much more than just bridge abstraction. Hack on the various cutting-edge applications that are uniquely enabled by Superchain Interop. Here are some ideas to get you started:

SuperloansSuperlendSuperCDP
Use collateral on ChainA and ChainB to execute an arbitrage opportunity on ChainA.Deposit ETH into lending protocols across chains for optimal yield, with automatic rebalancing based on best rates.Collateralized crosschain debt protocol that holds assets and issues a SuperchainERC20 on user preferred chains.
