# Risks & Parameters

### **Smart Contract Risk**

Aries Markets team tries our best to write safe codes and get internal and external code review before we open source them. The whole project has also been fully audited by the reputable auditing firm OtterSec before launching. With every line being carefully checked, we would still want to remind our users that related issues may arise.

To achieve the highest security standard, we have also set [bug bounty program](/aries-markets/security/bug-bounty.md) to minimize the possible risk of smart contract attacks.

### **Oracle Risk**

Aries Markets choose Pyth Oracle as our provider, which is backed by some of the most reputable trading firms and can be trustworthy. However, there could still be risk of an inaccurate or wrong price data is feed into our lending products.

### **Underlying Asset Risk**

Though we are very selective in listing new assets, we still want to remind our users that each asset within Aries Markets protocol has specific values related to their underlying risk, which influences how they are supplied and used in our protocol.

It’s crucial for our users to understand the underlying risk of each asset - all the borrows in Aries Markets is based on over-collateralization with a different asset, which may be subject to market volatility under certain circumstances. If the value of the collateral falls below a predetermined threshold, the deposit asset will be under the risk of liquidation.

The risk parameters listed below will help you mitigate potential market risks and identify collateralization and liquidation rules:

<table><thead><tr><th width="151">Asset</th><th width="128">Liquidation Bonus</th><th width="142">Optimal Utilization</th><th width="148">Optimal Interest Rate</th><th>Max Interest Rate</th></tr></thead><tbody><tr><td>USDC</td><td>1%</td><td>80%</td><td>9%</td><td>200%</td></tr><tr><td>APT</td><td>6%</td><td>80%</td><td>6%</td><td>100%</td></tr><tr><td>SOL</td><td>5%</td><td>80%</td><td>6%</td><td>100%</td></tr></tbody></table>
