AIR has made a significant breakthrough in the world of decentralized finance (DeFi) by introducing ERC-1919, a novel mechanism designed to combat the issue of liquidity being maliciously attacked by anonymous developers. This innovative solution is not only a game-changer for the DeFi space but also a testament to the power of collaboration and innovation in the blockchain industry.

The concept of ERC-1919 is surprisingly simple, yet effective. Unlike traditional Uni V3 or Uni V2 pools, which rely on a 50/50 LP model to determine prices based on supply and demand, ERC-1919 employs a multi-tiered grading mechanism. This approach eliminates the need for a DEX or LP to provide liquidity for the pool, making it a more efficient and cost-effective solution.

The mechanism works by using a predetermined Delta value of 0.8% per tier to determine prices. The number of tokens per tier is predetermined in the contract, ensuring that prices increase or decrease in a predictable and controlled manner. When demand surges, prices rise, and ETH earnings decrease relatively. Conversely, when selling pressure exceeds buying pressure, prices fall back to the previous level.

The advantages of ERC-1919 are numerous. For one, it eliminates the problem of transaction counterparty risk, as developers cannot rug after launching LP. This feature is particularly significant, as it provides users with a sense of security and stability. Additionally, ERC-1919 has the potential to be used in various future use cases, such as improved Dutch auctions and tier-based node sales.

In conclusion, the introduction of ERC-1919 by AIR is a significant development in the DeFi space. This innovative mechanism not only addresses the issue of liquidity attacks but also enhances the overall user experience. Its simplicity, efficiency, and potential for future use cases make it a game-changer for the blockchain industry. As the DeFi space continues to evolve, it is clear that innovative solutions like ERC-1919 will play a crucial role in shaping its future.
