At the Polkadot Summit, I was moderating the Cross-Chain Smart Contract Session and jotted down a few things I think can bring value to this discussion. These are particularly interesting when considering the use cases that could emerge from tapping into other ecosystems such as Ethereum (with precompiles that interact with Phala) or Cosmos (using Composable’s XCVM - a pallet that enables sending messages between CosmWasm smart contracts and Polkadot parachains).
One of my key takeaways from the session was that we need scope out some PoCs of cross-chain use cases that can be used as reference implementations for new builders in our space. Here were things that stood out to me during the session:
- CosmWasm smart contracts that can execute some compute on Phala network (or other parachains for that matter)
- Precompiles that correspond to extrinsics on Polkadot (for e.g. Phala)
- XCVM for Cosmos defi dapps that want to use Phala or Kilt or etc
- Games: use Phat contract for game + use Kilt DIDs + NFT chain
- Identity: mnemonic-less credentials using NFTs, or web3 names
- Smart contract based DAO gets rewards from some parachain (e.g. NFT chain)
@hashwarlock any comments on some of these / what’s the low hanging fruit? @Jafar - what do you think is missing to see some of these ideas come to life?
