Kraken has launched Nado DEX on the Ink Network, entering a testing phase. Nado DEX features an order-book matching system and a unified margin mechanism for both spot and perpetual trading. This system consolidates cash, spot positions, and unrealized profits and losses into a single collateral pool, enhancing trading efficiency. Nado DEX boasts a matching speed of approximately 5-15 milliseconds. It also introduces an NLP mechanism that allows users to deposit idle funds in USDT0 for market-making. This enables users to earn rewards from market-making and liquidation flows, with their positions serving as collateral for further trading activities.
