Stable Voucher will be used in the coming months to provide humanitarian relief. International KYC laws prevent free distribution of cryptocurrencies.
What it does
Stable Voucher is a system to create and cash out vouchers. A voucher's worth is pinned to the United States Dollar thanks to Dai and is spendable at approved vendors like grocery stores. Approved vendors are the only people permitted to "cash out" their tokens back to Dai.
How we built it
Stable Voucher is an ERC20 token deployed to the Ethereum Main Net. This means that your funds are secured by the decentralized structure of Ethereum.
Challenges we ran into
One challenging part of this hack was providing smooth communication between the web frontend and the Ethereum contract. Recent updates to MetaMask provided a few hours of tears. Nothing we couldn't figure out!
Accomplishments that we're proud of and What's Next
We are most proud that this is ready to use in the field! In just two weeks we will distribute and setup folks in a Universal Basic Income experiment in the South Pacific Ocean.
What we learned
We learned that you should always plan for more time spent in the integration phase between parts of your application. Whether frontend to backend, frontend to smart contract, or backend to smart contract, IT WILL TAKE TIME.
We also learned that the Crypto community is kind and welcoming! This was my first time in an event like this.
