Dynamic Weights

InterSwap introduces a new mechanic for the dynamic change of tokens weights during single-asset liquidity provision/removing. Adding Liquidity, proportionally increases the weight of the asset and vice versa: removing liquidity decreases the weight.

Liquidity provision/removing does not affect the quotes. Such a mechanic eliminates the possibility of draining the pool.

Let's take an example of such initial pool with equal weights:

Asset	Reserve	Weight Points
BNB	20000	1000
ETH	5000	1000
AVAX	45000	1000

Total Weight: 3000

We are adding liquidity with amount of 20 ETH. How much weigh points we should add to ETH?

price per point = reserve / points count.

$$p = a / (r / t)$$

Where

• p - points to be added or reduced.

• a - amount of tokens added or removed.

• r - current reserve of token.

• t - total points.

In our example: points = 20 / (5000 / 1000) = 4

Asset	Reserve	Weight Points
BNB	20000	1000
ETH	5020	1004
AVAX	45000	1000

Total Weight: 3004
