I have been using Little Fox all along, but it may only be a matter of time before this track is swallowed up by the exchange. I think the most suitable on chain business for the exchange is wallets, and this certainty is even greater than building a chain, integrating on chain applications, accepting exchange users, and connecting liquidity. This business is simply designed for the exchange, and if you can't do your own chain well, you can give up on attacking wallets.
