MangoBOX

MangoBOX is an Ink!-language fork and upgrade of Juicebox that runs in the Polkadot ecosystem, providing contract infrastructure for DAO fundraising. It keeps Juicebox's funding cycle design with discount rate, redemption curve and reserved rate: donations are released to projects by cycle, undistributed funds can exit through the redemption curve, and the remainder accrues to a community treasury. The team also built MangoSale, a fair launch protocol with fixed-price, fair-launch and Dutch auction modes. The treasury payout page supports automatic per-cycle execution, and donors can exit undistributed portions at any time; parameter changes require project confirmation, with cycle history and redemption records on-chain.

Funded by the Web3 Foundation, MangoBOX positions itself as Polkadot's public goods funding protocol, writing fundraising rules into contracts to cut governance cost, with contracts and front end deployed in the ecosystem and treasury balances and cycle parameters queryable on-chain in real time.
