The 'Promise Fund' is the milestone based fundraising that works as described above. The secondary type of fundraiser made available by Promise is the 'Yield Fund' which is more useful for one time causes and stands for yield generating fundraisers. Yield generating fundraisers allow donors to donate straight to the fundraiser or through a decentralized yield generating protocol which enables the donor to donate the interest earned and subsequently withdraw their initial deposit, therefore making a novel 'lossless' donation.

Milestone based funding allows donors to hold projects accountable as the pledged donations are only made available to the project if the donors vote in favor at the end of the milestone period. This mechanism allows for donors to donate to the current milestone round or spread the donation evenly across each milestone. If the donors vote against the project, then the funds promised to the remaining milestones are made available for withdrawal for the donors, therefore providing extra protection for donors. Milestone based funding is also perfect for early startups or projects looking to get funding without having to give up equity, while building an early community of donors that helped contribute to their success and proving their teams ability to make and meet their goals.

'Yield Fund' sets up easy and novel crowdfunding options for you! Some key features of this type of fundraiser includes:

• Straight Donation: This type of fundraiser allows donors to donate easily straight to the project using stablecoin assets.
• Interest Donation: Donors can utilize a novel interest donation to fund your project. Through this type of donation method the funds donated are reallocated to the AAVE lending protocol where the interest is made available to the owner, and the donor can withdraw their initial deposit.
• Time Lock: Determine how long users must keep their funds in the interest generating donation method before they can withdraw.

The owner of the project can call a maximum of 2 votes prior to the end of the milestone period. Each voting period is a minimum of a week to make sure donors and project owners can discuss and share their thoughts and progress and come to a decision. If the amount of 'Yes' votes is greater or equal to the amount of 'No' votes, the project met its milestone goals and gains access to the funds raised for that round. If an owner called for 2 votes and they both failed, the milestone did not meet its goal and the fundraiser has ended. If the owner has called for less than 2 votes prior to the end of the milestone period, then anyone can start a vote and the result of that vote is final. A successful vote immediately starts the next milestone round if it exists.

At the end of the Seed Funding Round, all the funds raised are made available for the fundraiser to withdraw. Once the owner withdrawals, the milestone rounds begin. At the end of each round, the vote determines who can withdraw their funds. A vote in favor of the fundraiser, allows the owner to withdraw the funds raised for that round. A vote against the fundraiser allows each donor to withdraw the amount they donated to that current milestone and any remaining milestones if they exist.

Donors can only withdraw in a 'Yield' fund when they donate through the 'lossless' donation method and after the specified timelock. The timelock is set by the owner of the fundraiser and specifies the amount of time a donor has to keep their funds locked in the yield generating protocol prior to withdrawing their funds.

There are two different types of badges, representing the two different types of fundraisers that are available on our platform. The purple badge with the letter 'P' represents our milestone based fundraiser, 'Promise Fund'. The yellow badge with the letter 'Y' represents our yield generating fundraising, 'Yield Fund'.
