Four documents, the same five questions.

No throughput league table and no yield. The cells are what this library is willing to say about the text.

QuestionUniswap v2 Core
What the text proposesThe 2020 core paper for Uniswap v2: a constant-product automated market maker, with arbitrary ERC-20 pairs, price accumulators, and a flash-swap callback. It is the clearest short specification of the pool that much of later DeFi either forked or assumed.
Who may writeHayden Adams, Noah Zinsmeister, Dan Robinson
What is settledThe invariant is the product of the two reserves, up to the fee. A trade moves the reserves along that curve.
Load-bearing assumptionThe invariant is not a promise of a good price. It is a function of reserves.
What this library says afterwardsDivergence loss is not a bug in the paper. It is the cost of the curve.
