A decentralized crowdfunding smart contract built with Reach
This crowdfunding smart contract consists of two actors: Artist (1) and Fan (multiple). The Artist user deploys the contract to raise funds for their project and defines a goal. Multiple Fan users can connect to the contract and add funds to the crowdfunding campaign by choosing different perks from a list. Fans store their contributions in the contract. At the end of the campaign, the Artist gets the funds transferred to them.
Do $ reach run or $ ./reach run on the home directory, depending on where you reach installed on your environment.
Follow the command line prompts for Artist or Fan user.
-
Allow fans to select between all-or-nothing mode (Kickstarter style) or all-or-something (Indiegogo style) campaign modes. In the All-or-nothing crowdfunding mode, the Artist gets the funds in the contract only if thy reach the original goal. The Artist gets all the crowdsourced funds in an All-or-something mode, regardless of the goal reached.
-
Allow users to recollect/harvest the funds from an All-or-nothing campaign if the artist doesn't reach the goal.
-
Allow Artist users to dynamically set the crowdfunding perks outside the contract by referencing a data repository.
