Cross-Pool Fee Streams in JACKPOT: Receiver Rights, Version Drift and Accounting Boundaries

JACKPOT is a Uniswap v4 hook that runs separate largest-single-swap and largest-single-donation games for each currency across its pools. A provisional leader becomes an active fee receiver only after its deadline and settlement. This public-source study reproduces 40 of 41 ordinary test cases, including nine actual-local-PoolManager integration cases and three 1,000-run fuzz properties. A unit case's executed schedule never reaches its deadline; a separate invariant fails because it excludes extant dead-address sink balances while expecting supply-reducing burns. Two added diagnostics confirm settlement at stored deadlines and conservation when sink balances are included. The source differs from older documentation in fee allocation and remaining owner control. The report preserves the mixed results and recovered-dependency limits; it is not a live deployment verification, audit, economic guarantee or measured inclusion result.Jarett Dunn.
