Live AMA with Hayden + v2 Walkthrough
summary
Uniswap v2 launches with concrete changes: support for arbitrary ERC-20 pairs, a new on-chain price accumulator oracle design, and atomic flash swaps added into formally verified contracts; core pair contracts remain minimal while helper contracts handle routing, oracles and UX. A minting minimum prevents divisibility griefing. Fee stays 0.3% for competitiveness; no upgradeable contracts to preserve trust. About $11–12M migrates to v2 within days (~25% of liquidity), and optimistic rollups are the expected Layer‑2 path.
