1.How to trade on MCDEX?
Please refer to the tutorial: 【V3】How to trade on MCDEX V3?
2.How to conduct liquidity mining?
LP only need to provide one asset to the pool to join the liquidity mining. When V3 launches, USDC pool will have a liquidity mining program for 14 days. The reward will be 0.15 MCB per Ethereum block for all the LP in the mining pool.

3. Staking details after the mainnet launch
There is a community discussion going on on forum:
We don’t have a conclusion yet, seems there is a controversy going on. Feel free to leave your thoughts on the forum.
4. Why is the entry price and the marked price different
Entry price means the average executed buy/sell price of your current position, which is fixed after you have a position.
Mark price is the price at which the perpetual contract is valued during trading hours. It will change continuously based on the spot market move.
So these two prices are totally different.
5. Is placing a limit order safe? By any chance that others might detect this order info and attack? (For example, Sandwich attack?)
Currently, we are using the broker for a limit order, which is a relatively centralized way. It’s less safe than our market order. It could be attacked by the sandwich attack if both the broker’s private key and the broker’s signature are stolen. In this case, users will get a worse deal than he could have got.
However, in defi space, there are two ways to implement limit order. 1. on-chain limit order 2. broker model like we do. Both ways actually have the same level regarding safety.
6. What is the composition of the fee?
For traders, they will need to pay gas fee and transaction fee.
Gas fee will be about 1/100 of that on Ethereum on mainnet.
Transaction fee will be set by operators - creator of the perpetual market. For pools operated by DAO, the transaction fee will be 0.07%, 0.015% of which will go to DAO Vault, 0.055% will go to LP.
But we will have transaction mining program going on when launching, please refer to https://forum.mcdex.io/t/proposal-25-launch-liquidity-mining-and-transaction-mining-when-v3-launch/384 for details.
7. What is the maximum position I can open?
the maximum position that you can open is limited to the following 3 points:
- collateral * target leverage
- AMM leverage
- Every pool has a maximum open interest
8. Will the liquidation price change?
Yes, it will slightly change when you are holding the position. It is caused by the funding rate you received/paid.
9.Will there be any cost when closing the position?
Nope. There will be no cost when closing positions.
10.Will a pool be tradable when there is no LP?
Nope. The pool needs some decent liquidity to be tradable. Liquidity is crucial for an AMM-model-powered DEX.
