According to Foresight News, Degen launched a new mechanism called ERC-1919 on AIR on Base a few days ago. This mechanism is designed to solve the problem that liquidity in DEX transactions may be maliciously attacked by anonymous developers. The operation of ERC-1919 is relatively simple, without the need for DEX and LP to provide liquidity for the fund pool. It adopts a multi-level tier mechanism, and the price increases or decreases at a predetermined Delta value of 0.8% per tier. The number of tokens in each tier has been predetermined in the contract. If demand surges, the price will rise and ETH earnings will be relatively reduced. When the selling pressure is greater than the buying pressure, the price will fall back to the previous level. The advantage of this system is that users can clearly know what benefits they will get from the system. In addition, this mechanism has potential in various future use cases, such as improved Dutch auctions, tier-based node sales, etc.
