This dapp was built by Keisaku Higa while his internship at Flex Dapps. This dapp's smart contract utilizes rToken contract and Compound so that the users can deposit their DAI into this dapp to earn interest from Compound protocol. The generated interest will be transferred to Flex Dapps' account using rTokenContract. After the generated interest amount reaches the certain level, Flex Dapps will issue their original hoodies to users who deposited DAI into this dapp.
- Here is the dapp's prototype: https://frosty-bardeen-857d6e.netlify.com/
- The front-end code is here: https://github.com/morelazers/flex-swag-portal
- Hoodie contract address: 0x890787cd8ea42C24c09E2c2565e4424429653925
- DAI contract address: 0x5592EC0cfb4dbc12D3aB100b257153436a1f0FEa
- rDAI contract address: 0x6AA5c6aB94403Bdbbf74f21607D46Be631E6CcC5
A user will be given the 1st position in the waiting list
A user will be given the last position in the waiting list
A user will be removed from the waiting list
Case4 - When an existing user who is not in the waiting list tops up their deposit and the amount reaches the minimum amount
A user will be added into the waiting list and given the last position
The user will be given the last position and the 2nd position user will be the next recipient
Case6 - When the 1st position user redeems their rDAI and becomes out of the waiting list before the generated interest amount reaches the hoodie cost
The 2nd position user will be the next recipient
No one receives a hoodie and the generated interest amount will be transferred to Flex Dapps’ rDAI account
- Users can change their rDAI hat to the dapp’s one before using
- Users can approve of the dapp transferring their DAI to Compound
- Users can mint rDAI through the dapp
- Users can redeem their rDAI and the DAI they deposited will be given back to them
- The generated interest will be redirected to the Flex Dapps’ rDAI account for the hoodie cost
- Hoodie will be given to the 1st position user automatically when the generated interest amount has reached the cost
