After talking to a few potential users, the vote was unanimous—it would feel more user-friendly if ‘money-related matters’ came later. Therefore, we decided to let the user choose the design first before picking the charity.
Another challenge was finding the easiest way to send the card. Since each card is an ERC721 token, the standard way would be to send the card to the Ethereum wallet address. However, we found that this method would be less intuitive for new crypto users and would create many frictions along the way.
We solved this problem in the first version by using the deep linking method. Every newly minted card is hosted on a URL extension that is attached to the message for the recipient. The card can then be viewed by just entering the link in the browser, even when the recipient does not have a web3 wallet installed.
After intense two and a half weeks of building, designing and hassling, we finally launched RadiCards on 5 December, 2018.
The feedback from the community was phenomenal.
We were mentioned by the EFF and retweeted by Cory Doctorow and others. At the end of 2018, RadiCards had an opportunity to present at the Chaos Computer Club #35c3, one of the planet’s biggest and most important conferences for hackers.
As a result of a few weeks of hard work on a zero budget, we successfully helped raise the fund for charities, gained many new friends and introduced the world to the first-ever crypto ecard.
