Automated Market Makers (AMM) no longer rely on traditional buyers or sellers in the financial market, but instead, keep the ecosystem liquid through liquidity pools.

Automated Market Makers (AMM) constitute part of the decentralized finance (DeFi) ecosystem. They allow non-custodial and automated trading of digital assets through liquidity pools instead of the traditional buyer and seller market. AMM users provide encrypted tokens for the liquidity pool, the price of which is determined by a constant mathematical formula. The liquidity pool, which can be optimized for different purposes, serves as an important tool in the DeFi ecosystem.

What is the automated…

There is a story about the birth of Turtle Coin in the crypto world:

On a chilly night in December one year, encryption enthusiasts RockSteady and Bebop were drinking and chatting outside. After a few drinks, they were slightly drunk. They complained that the world was filled with counterfeit products incapable of development. Bebop held that many crypto projects had raised a lot of funds without concrete products. Without a dedicated team, serious marketing, and formal funding sources, it is impossible to build a useful blockchain project.

Fingering his beard, RockSteady looked at Bebop seriously. He had only one thought…

DEX has ushered in exponential growth since the summer of 2020. Automated market maker (AMM) platforms represented by Uniswap have become the mainstream choice in the market, but users have also suffered the impermanent loss while providing liquidity. Due to the subsequent risk of volatility, the value of assets in hand will shrink invisibly.

The possible risks of AMM have inspired DeFi’s enthusiasm for innovation. The decentralized trading platform DODO has innovatively proposed a next-generation solution for liquidity supply — the proactive market maker (PMM) algorithm. It reduces impermanent losses and holding risks, and realizes the flexible…


  1. With the network fully utilized, we’re closer to the goal of the “global settlement layer”
