# FAQS

**Q1: What is CrusSwap?**

[**Crus**](https://crus.xyz/) is a decentralized exchange (DEX) on [**ZkSync**](https://zksync.io/) that allows users to trade tokens in a permissionless and trustless manner. It provides flexible liquidity management and optimized trading paths, which can help increase capital efficiency and reduce slippage.

**Q2: Is CrusSwap open-source auditing?**&#x20;

CrusSwap is currently being audited and will continue to be audited by various security companies.

As CrusSwap has more contract code than other swaps, the audit will take longer.

**Q3: What are the advantages of CrusSwap compared to other DEXs?**

1. **Less slippage:** Liquidity is concentrated in the price range where most transactions occur, resulting in less slippage and fewer losses, especially for stablecoin pools.&#x20;
2. **Transaction rewards:** Each transaction is charged with a fee of 0.2% as other exchanges on zksync, however, with CrusSwap users can earn more rewards from each transaction they make.&#x20;
3. **Transaction fee refund for LPs**: LPs can earn transaction fee refunds by adding liquidity in the range where transactions occur, and they can earn more if there are more transactions in that range. This fee income is particularly pronounced on base currency pair ETH/USDT, which typically offers an APR of more than 200%.&#x20;
4. **Yield Farming** can be combined freely with a variety of trading strategies: CrusSwap allows LPs to convert multiple liquidity provision portfolios under changing market conditions in order to obtain more profits.&#x20;

For example, when currency prices are volatile, conservative users can choose to adjust the range to minimize the impermanent loss. But even then, you will still get a better return than a traditional order.&#x20;

Market-making can be done with just one currency, which helps users automatically buy in or sell their tokens.&#x20;

**5. Higher overall return:** CrusSwap offers triple incentive, multiple income and higher APRs. The APR for stablesoin pools, for example, are often higher than 50%, which is hard to see on other protocols.&#x20;

6\. CrusSwap is built on zksync, which means **smoother speed and lower gas fees**. So in general it cuts the cost of switching positions, so users may adjust their positions according to token price.

**Q4: What is the triple incentive? Do you mean CrusSwap is offering more rewards than other DEXs?**

CrusSwap provides users with more incentive and portfolio management strategies than other DEXs. Users can choose to be more aggressive or conservative according to their preferences.&#x20;

**1. Transaction Fee Refunds**: LPs can get transaction fee refunds if transactions occur in the range they set. Take USDC/ETH pool, a routing pair or base currency pair, as an example, LPs can earn the fees in the form of USDC or ETH. The value for this specific pool is higher than other trading pairs because of its higher trading volume.&#x20;

**2. Transaction Rewards:** Each swap will charge a fee of 0.2%, and users can get CRUS reward after completing the swap, which greatly reduces their costs and stimulates the trading volume.&#x20;

**3. Yield Farming:** LPs can obtain CRUS tokens by depositing specified token assets as required to provide liquidity to the liquidity pools. Currently, CrusSwap actually offers higher yields than other DEXs.&#x20;

While 99% of users currently opt for the pools with a 0.2% fee tier, you can also choose those with 0.1% or 0.5%. But currently, only pools with a 0.2% fee offer transaction rewards, and perhaps there will be some adjustments to this in the next. In general, 0.1% fee pools are best for stablecoin pairs and 0.5% fee pools are best for exotic pairs.

**Q5: What are the benefits of concentrated liquidity by CrusSwap?**
