Hi Max!
We have a motion proposal about “General Integration” (Long Term R&D: General Integration (Proposal)) which will comprise, among other topics, integrations with other blockchains and oracle providers. Chainlink integration, also with their upcoming Cross-Chain Interoperability Protocol (CCIP; Cross-Chain Interoperability Protocol (CCIP) | Chainlink), is something of relevance there. Also things like an integration with Polkadot as mentioned in one of the threads should be discussed as one option to integrate with existing integration layers.
