BSC to Ethereum, Kusama to Polkadot?

Last September, Binance Smart Chain (BSC) launched, ushering in a new era of exchange blockchains and quickly attracting a large number of projects. Within just one or two months, tracks like AMM, lending, stablecoins, and NFTs had basically taken shape. In December last year, Huobi's Heco chain ignited the second wave of exchange chain enthusiasm. Subsequently, OKEx chain, after launching transfer, trading, and mining functions, is also about to launch its EVM module to support smart contract development. Exchange chains are currently a major hotspot in the industry and will continue for a considerable period of time.
