A CosmWasm smart contract, written in Rust, that instantiates a “Quadratic Funding Round”, and has the following functionality:

• Coins sent with contract instantiation goes into the common funding pool, to be reallocated based on the Quadratic Funding formula.
• Contract parameterized by a list of whitelisted addresses who can make proposals, and a list of whitelisted addresses who can vote on proposals. Empty list means permissionless proposals/voting.
• Proposers can make text based proposals via contract function calls, and set the address that funds should be sent to.
• Proposal periods / voting periods are either defined in advance by contract parameters, or are explicitly triggered via function calls from contract creator / admin. If periods are triggered via function calls, minimum proposal periods / voting periods should be set upon contract instantiation.
• Voters vote on proposals by sending coins to the contract in a function call referencing a proposal.
• Once voting period ends, contract creator / admin triggers the distribution of funds to proposals according to a quadratic funding formula.
• A web based user interface (using CosmJS) with the following functionality:
• Allows instantiation of a new contract / creation of new proposal round
• Enables sending of proposals, and voting on proposals
• Enables viewing all proposals and votes for a given contract / Quadratic Funding Round
• Video demo showcasing functionality of your Quadratic Funding dApp!

• Support for alternative funding formulas (besides the standard quadratic funding formula)
• Support for structured proposal metadata
• Support for multiple funding rounds per contract
• Variable proposal periods / voting periods
• Support for more fine grained queries like “get proposal text/metadata by proposal ID”
• Regen Network / OpenTEAM logos & branding represented in the UI
• Deploy your contract to the CosmWasm coral testnet, and share a working link to your dApp

First iteration will only support single type of native coin.
