If you see twitter page of CATA then its very much clear that they are focusing on FLOW blockchain thats because they have partnered with FLOW to provide storage solution for NFTs. FLOW is biggest player in NFT domain.
FLOW is no doubt one of the biggest player in the field of NFTs and with time its growing. I guess CATA has made a right decision at very right time and this will defiantly benefit them in long run.
