A significant challenge associated with the initial generation of stableswap's closed liquidity pools is the fragmentation of liquidity, which prevents different pools from sharing their liquidity, thus resulting in increased slippage for users. Additionally, other stableswap designs typically necessitate the inclusion of multiple tokens of equivalent value within a pool, complicating the overall pool structure by requiring the pairing of liquidity provider (LP) tokens with various new tokens. This complexity severely limits the scalability of the system and negatively impacts the overall user experience. In response, Platypus introduces an innovative automated market maker (AMM) on the Avalanche network that features an open liquidity, single-sided AMM that autonomously manages risk according to the coverage ratio, thereby maximizing capital efficiency. Central to Platypus's architecture is the principle of asset liability management (ALM), which sets it apart as the pioneering platform to implement a single-variant slippage function in lieu of conventional invariant curves. Overall, the design of Platypus's open liquidity pool not only enhances capital efficiency but also significantly reduces slippage rates in comparison to traditional stableswaps, ultimately providing a more streamlined and effective trading experience. This advancement positions Platypus as a leader in the evolution of decentralized finance solutions.
