L2 Transfer
What's the difference of transfer between L1 and L2?
A: The basic function is similar for users to transfer certain assets to other users. In L1 wallet, you enter L1 address to make transactions, while in L2, you could only transfer to L2 address with zecrey suffix. And in L1 users could only transfer to one address at one time in L1, but in L2 one-to-many transfer, you could transfer to more than one receiver.

4.The amount of transactions in L2 has a bottom limit of 0.0001. Transfer amounts lower than 0.0001 will lead to failure or abnormal conditions, such as the transfer amount in the record as zero.
​
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. Due to the insufficient depth of the token pool during the test period, there are certain discrepancies between the swap price and the real market price.
How to Swap in L2?
1.Click "Swap" and select a token pair you wish to exchange.
2.Enter the amount and choose one token for gas fee. There will have several tokens that could be burned as gas fees for swap, as REY, ETH, MATIC and NEAR, etc.
3.When you select REY as gas fee token, you will get a 20 percent discount.
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.
3.Select a token for gas fee and confirm the transaction.
