Once, stablecoins were like an invisible pipeline system in the crypto ecosystem—only noticed when it broke. But recently, the situation has changed. As more and more people treat on-chain balances as everyday funds, the importance of US dollar liquidity has shifted from an exclusive need of arbitrageurs to a universal necessity. A project aims to address this shift with a new approach: obtaining US dollar liquidity without selling the assets you truly want to hold. The method is actually simple: lock in the assets you already own, then mint USDf (a over-collateralized synthetic stablecoin). This way, you can retain your original position while gaining on-chain liquidity support. For users who are long-term bullish on certain assets but need US dollars in the short term, this mechanism opens up new possibilities.
