The most popular AMM, Uniswap, is annualizing to $1 billion in fees. That’s a chunky amount of value for its users.
The team has just released the third version of its protocol, and it is an innovation in the structure of the AMM logic. Instead of providing liquidity across the entire price curve, users are now able to specify pricing ranges for which they are participating in the curve. This protects market makers from the extreme price fluctuations which they may prefer not to fund. Because most trading also happens in narrower price bands, it is possible that capital is much more actively used in those bands, and generates higher fee returns comparatively.
