QuantAMM is a blockchain protocol that introduces Temporal Function Market Making (TFMM) for on-chain quantitative asset management, focusing on Blockchain Traded Funds (BTFs) rather than core liquidity providing. It aims to facilitate DeFi passive products for institutional use by offering compliance-ready on-chain feature hooks. The protocol leverages novel estimators to enable traditional portfolio management strategies within the DeFi space, emphasizing regulatory compliance and efficiency in fund rebalancing.
