Too much oracle project this day. Chainlink, aeternity, and there were so many orcale project these days and what makes you feel if crosschain project has a very huge potential to growth? It sounds like you are over optimistic dude. I have seen some platforms that focused to create cross chain ecosystem already failed to achieve their target. Let say ark is one of them.
The partner of band called cosmos has already faced a very difficult time with its token price.
On the contrary, the cryptospace is greatly underserved by oracles currently. LINK, BAND, Tellor and maybe one or two others are the only projects focused on the oracle use case. Smart contracts are a key use case of crypto, and there are many smart contract platforms, but they are of little use without oracles providing the link to the 'real' world outside their blockchains. The oracle space has enormous room to grow.
