What's Automated Market Making (AMM)

What is Automated Market Making (AMM)?

Automated Market Making (AMM) is a protocol that automatically calculates buying and selling prices according to a formula to provide a continuous quotation for the market. In terms of trading mechanism, CoinEx combines AMM with the order book, and the system automatically converts the liquidity pool into an order book.

CoinEx AMM allows every user to become a market maker. By adding liquidity to the liquidity pool, users can share the trading fees earned by CoinEx.

 

About AMM Algorithm

CoinEx AMM uses the "Constant Product Market Maker" model, which means users need to deposit two different cryptos into the liquidity pool, and the product of a trading pair's balances remains unchanged.

There are two algorithms applied by CoinEx:

1. "Infinite Constant Product Market Maker" algorithm: mainly adopted in non-stablecoin markets, e.g. CET/USDT. This algorithm provides market liquidity no matter how high or low the price is.

2. "Finite Constant Product Market Maker" algorithm: mainly adopted in stablecoin markets, e.g. USDC/USDT. This algorithm provides market liquidity in a specific price range, improving capital utilization. 

 

What is Liquidity Pool?

Liquidity pool contains the assets used for AMM. Based on the "Constant Product Market Maker" model, the total value of each token in a liquidity pool must remain the same. Liquidity Providers (LPs) will gain 50% of the trading fees generated in the pool by adding liquidity. The daily profits also will be added to the pool, and can be withdrawn all at once when the liquidity is removed.

In AMM markets, each trading pair has a liquidity pool that contains two assets and executes the rule of trading assets, and adding or removing liquidity.

The rule stipulates that the total value of each token in a liquidity pool must remain the same. Therefore, when the amount of token A decreases, the amount of token B should increase according to the formula X * Y = K (a fixed constant).

 

What is AMM Market?

Any market that supports automated market-making is an AMM market. The AMM market uses a different fee system. VIP does not enjoy any rate discounts, and using CET to deduct transaction fees is unavailable.

How to Profit via AMM?

CoinEx AMM income mainly comes from the trading fees returned by CoinEx. All users who provide liquidity to the liquidity pool of AMM can get 50% of trading fee in the market, according to the proportion of the liquidity pool.

Take CET/USDT as an example:

Suppose CET/USDT market has made 10,000 USDT in trading fees in an hour.

If your liquidity takes up 1% in the CET/USDT liquidity pool for the hour, you will get the following income:

10,000 x 100% x 1% = 100 USDT

10,000 x 100% x 1% = 100 CET

Note: The trading fee ratio of all CET markets is 100%.

Risk Warning

The assets in the AMM Account will be added to the liquidity pool for automated market making. Due to price fluctuations, impermanent losses might occur and the amount of the two assets might change when the liquidity is removed. 

Impermanent loss will gradually be wiped out when the price ratio changes back and eventually, users can gain profits from providing liquidity.
