From NFT Baskets to Multiple Quote Markets: Atomic Batch Composition and Control Boundaries in Scooper

Moving NFTs from several collections into tradable markets normally requires coordinating custody, vault creation, funding routes and liquidity positions. This report examines Scooper, a contract that composes those actions across collections and quote currencies in one execution after the necessary approvals. It deposits NFTs into collection vaults, divides claim and native-currency budgets by configured weights, converts selected budgets into other quote tokens and creates liquidity positions. A complementary path deposits and sells NFTs into existing native-currency pools with an aggregate minimum output. A fresh isolated build passed 22 local tests: five Scooper-specific examples and 17 inherited tests of the supporting vault and router system. The examples establish successful two-collection, two-quote composition, repeated vault reuse, claims-only placement, batch sale and input rejection in controlled fixtures. Source inspection identifies limits involving newest-vault selection, route slippage, residual balances and optional locking. These findings describe an engineering composition and its control requirements, not guaranteed liquidity, universal compatibility, profitable disposal or financial inclusion.
