Sui (SUI) is a layer-1 blockchain with an object-centric data model and Mysticeti consensus, settling transactions with sub-second finality. On U.CASH, SUI runs on the partner rails: buy it with card or bank and sell it back to fiat through the on-ramp network, and swap it against BTC, ETH, USDT and 1,500+ assets through the instant-exchange network, always delivered to your own wallet. SUI is not a U.CASH wallet or checkout network.
