It's not yet available on CMC or coingecko and as far as i know sovryn didn't have api to be integrated with CMC and coingecko. it seems like babelfish needs to create its own API to be connected with CMC and coingecko.
As far as I know, Sovryn has made a small effort to come to CMC with native ESOV tokens on Ethereum based on native exchange price API data on Uniswap. Compared to current expansion and development defi systems, Sovryn is still a small and budding platform. The first launcher on their Rbtc root chain just got Babelfish. It's an improvement on their part though
Transaction costs with rBTC on the RSK network are quite good. I only lost 0.14$ for one smart contract call. It is cheaper than BSC and a lot lower than Ethereum. I think DEFI with the RSK network is great, it satisfies Bitcoin enthusiasts and DEFI very good experience. I don't know if bottlenecks happen as people use them more?!
