The market has been quite volatile lately, and everyone probably still remembers the liquidations.

Many people summarized JustLend DAO's SBM V2 in one sentence — isolating the risks.

After looking at @DeFi_JUST's upgrade, what I care more about is another change: different collaterals no longer have to borrow on the same credit table.

Anyone who has been through liquidations knows that the page says it's safe, but in reality, positions can't hold for long. Price, oracle, liquidity, liquidation efficiency — if any link falls behind, the market won't wait for you.

JustLend's SBM V2 uses a two-layer structure of Vault and Market. The Vault aggregates liquidity of a single asset and then allocates funds to multiple independent Markets. Each Market only accepts specific collateral and borrowing assets, with its own independent risk boundaries.

If a highly volatile collateral drops sharply, the pressure mainly stays in the corresponding Market and does not easily spread to other markets.

Isolated markets solve the problem of where risk propagates. But how much can be borrowed in this Market, when liquidation occurs, and how the interest rate changes when funds are tight, all depend on its own parameters.

The most critical among them is LLTV, which can be understood as the credit warning line. How deep the position is borrowed and at what price a liquidation may occur are all related to this line.

V2 also uses the Adaptive Curve interest rate model. When Market utilization is low, the interest rate curve can shift downward to attract more borrowing demand; when utilization rises, the curve shifts upward to encourage repayments and liquidity return.

The oracle manages price input, and the combination of collateral and borrowing assets determines what kind of risk this Market is taking. These mechanisms together set the true credit conditions for a collateral.

Assets with higher volatility, shallower liquidity, and more fragile price sources should not share the same borrowing boundaries as mature assets. This is the most noteworthy point of SBM V2.

Risk has not disappeared; it's just that after being broken down, conditions can be set according to each asset's own situation.

Boundaries must be clearly defined. Independent Markets reduce cross-market contagion, but risks within a single Market still exist. Collateral can still drop, oracles must remain stable, and liquidation must have sufficient liquidity.

The launch of V2 does not mean V1 has no value. The two models serve different asset types and risk preferences. There needs to be a balance between capital efficiency and risk isolation.

When the market is hot, everyone prefers to compare APY. After going through several cycles, I will first look at the credit space a protocol gives to an asset and where risk stops when the trend reverses.

APY tells you what you might get in a favorable wind. LLTV, price source, and liquidation liquidity tell you how the system prepares to handle a position when the wind turns against you. Next time you see a high-yield Market, will you look at the APY first, or its LLTV and price source?
