Swap
Why is the swap price in L2 different from the market price?
A: The swap of L2 is in the DEX based on automatic market maker (AMM). Its exchange rate mainly depends on the amount of fund in the token pool in the smart contract of the system.

4.It might take a few seconds to generate witness and confirm the transaction.
​
Add Liquidity
What is Add Liquidity?
The liquidity pool is a pool of tokens locked in a smart contract to increase market liquidity among traders. A liquidity pool has two kinds of tokens, which is a trading pair. When a new liquidity pool is created, the first liquidity provider (LP) will set the initial price in the pool. If that price in the pool is inconsistent with the global market, there will be profitable arbitrage opportunities and the LP will suffer impermanent losses. So the LP is incentivized to keep the exchange ratio of the two assets close to the market price. LP will receive tokens as a reward for providing funds and liquidity to the liquidity pool.
How to add liquidity?
1.Click "Add Liquidity" and select a token pair.
2.Enter the amount you wish and the system will match the token ratio automatically.
