I'd like to see support for Binance Smart Chain. This should include swaps, liquidity, etc. All the same stuff that is being done today on Sushiswap, Uniswap, and similar is happening on BSC using things like BurgerSwap, PancakeSwap, etc.
You can start with supporting BSC Blockchain import -->
https://www.bscscan.com/ this seems to be identical to etherscan.com, so the api calls may be the same or similar.
