The lawsuit, filed in the U.S. District Court for the Southern District of New York, specifically centers around Bancor’s Constant Product Automated Market Maker (CPAMM) model. Bancor is a liquidity protocol with a total value locked (TVL) of around $59 million, according to DeFiLlama. Patented in 2017, the CPAMM mechanism enables on-chain token swaps without the need for order books.
