Many people have faced this dilemma: they see good prospects for the assets in their accounts and don't want to sell, but in real life they urgently need cash. Should they grit their teeth and sell at a loss, or hold on without liquidity? Actually, there's a third way.

The core idea is straightforward: keep your assets intact while extracting liquidity from them. It may sound like a fantasy, but the underlying mechanism is actually simple.

You can lock your cryptocurrencies, stablecoins, or even tokenized real-world assets into the protocol's "vault." These assets still belong to you, but are frozen as collateral. The system will then mint an over-collateralized stablecoin—such as USDf—based on the market value of the collateral. This stablecoin can be used directly on-chain for transfers, payments, and even staked into earning versions like sUSDf to generate fixed income. In other words: preserve your position while activating your funds.

Why is supporting a variety of collateral types so crucial? Traditional DeFi protocols usually only recognize a few mainstream assets as collateral. But if the system can accept a broader range of assets, two important changes occur: users don't need to significantly alter their investment allocations to borrow; and real-world assets like bonds and commodity tokens become easier to integrate into on-chain finance. As tokenization of assets becomes a trend, the value of this multi-asset engine will be fully realized.

The core logic of these products isn't about offering astonishingly high yields. The key selling points are transparent mechanisms, ample over-collateralization protection, and predictable, stable returns.
