MCFAM Seminar - Convexity costs in Automated Market Makers
Speaker: Eric Falkenstein
Abstract: The most common blockchain trading contracts are based on a constant product rule, a*b=k, which subjects liquidity providers to negative convexity. This ‘gamma cost’ for most contracts exceeds fee revenue. A solution is proposed to remove this cost by incenting liquidity providers to act as price-setting arbitrageurs while also preventing a subset of LPs from dominating the others.
