[ANN] Metaswap: DEX based on dynamic fee rate to solve front-runner attacks

[summercat]

Metaswap solve the front-running-attacks problem commonly faced in the AMM mechanism, which will bring huge losses to liquidity providers and real traders, which will exacerbate the unfair distribution of benefits between arbitrageurs and participants. When designing Metaswap, we adopted a dynamic fee rate mechanism to greatly reduces the profitability of arbitrageurs.

Metaswap's price model:

           f(x+△x,y-△y )=k*(1+π(ρ))

Where x,y respectively represent the balances of the two assets A and B in the pool;  △x,△y  represent that a trader exchanges △x of A for △y of B; k is a fixed constant, Similar to a constant in other AMM trading models;ρ is the transaction ratio coefficient, defined as  ρ= △x/(x+△x) ; π(ρ) is an adjustment function, in principle  π(ρ) is an increasing function of ρ.

Designing an automated market maker that can't be attacked is probably fairly hard. I think this concept deserves more attentions.

At first glance, I thought it was metamask that launched metaswap. How about the economic model?

The market needs a good DEX to maintain the fairness of participants. We have found such a method in a certain mathematical model and can't wait to share and discuss with you.

Metaswap's website has been launched. Introduction and price model are announced on the website. Metaswa's white paper will be  opened soon. If you have any questions, welcome discuss in the forum.

Can i understand this way, in uniswap, x.y=k. but in metaswap, x.y=k*(1+π(ρ))

In fact, in uniswap, the price is only related to the quantity of the two assets. In metaswap, the price is also related to the rate, and the rate is positively related to the proportion of transaction assets. By adjusting the rate, the arbitrageur is unprofitable

is there any telgram or twitter?

is there any telgram or twitter?

When the white paper comes out,  the slippage problem is really solved, we can build dicord by ourselves

[summercat]

Metaswap's white paper has been finished, which refers to well-known AMM models such as Bancor, uniswap, and Balancer protocol, and proposes a solution to the problem of front-running attacks. Please continue to pay attention to the development of the project.

According to your paper, 0 < ρ < 1.
for some ρ greater than a certain critical value, will there be △y < 0?
