Many people have experienced this awkward situation: holding promising assets like Bitcoin and Ethereum, but when they need liquidity for daily expenses or other investment opportunities, they are forced to sell. Even more heartbreaking is that after selling, the market turns around and rises, making the seller regret it more than anyone.

The root of the problem is that we are always forced into a binary choice—either hold onto the assets tightly or sell them completely. Is there a way to enjoy both?

The design concept of the USDf stablecoin is to break this deadlock. Users can lock in Bitcoin, Ethereum, stablecoins, or tokenized real-world assets (such as government bonds or gold) within the protocol, then mint the corresponding USDf for use, while retaining full ownership of the original assets.

The brilliance of this mechanism lies in its over-collateralization model. The value of the collateral assets always exceeds the amount of USDf generated, so market fluctuations cannot undermine the system's stability. More importantly—each USDf is backed by verifiable, real reserve assets. The entire process is transparent and on-chain, allowing users to check reserves anytime they want. This verifiability has been lacking in many stablecoin projects. Historically, most failed stablecoins fell because of lack of transparency.
