Welcome to Season 5, your project name is really giving me a good laugh :joy:
I’d have to circle back with my feedback when I quench my humor haha :laughing:
Welcome to Season 5 once again.


Welcome team, please is this win-win for all depositors? You earn some interest on the amount you deposit and win extra if you are lucky. Is that how it works?


Welcome to Grand Hackathon Season 5
Please what do you mean by 2USDLP ?

Thank you very much, let’s build together!

Thank you Manfred,
It took almost a week for us to come up with the name. Hope you like it!

Actually it’s not for all depositors, but all depositors will have a chance to win the lottery even if they only deposit 2$. For small amount of deposit, you can earn not much interest but it can be a significant amount on Dafatcat!

USDLP is the token you receive when you deposit on Justlend, you can deposit it on DaFatCat to join the lottery, and 2 is the minimum amount.

We’re upgrading our system so that users can deposit USDD directly on DaFatCat

Thanks you Vinny. Let’s grow together!

First of all, how did the team come up with the name DaFatCat? What’s the story/history behind the name?

And I clearly read about your transitioning from Phase 1 to Phase 2 and I can’t help but ask, what major challenges did you face during this transitioning and how did you overcome them?
Thank you!

So the 2USDLP is equivalent to 2USDD right?

Meaning some depositors will get nothing? This is like betting, it will be based on luck or


Actually the name was inspired by an Asian Lucky Cat, he brings lucky to his owner

Tbh there are not much difficulties in the first phrase but designing a good UI/UX for the website is a major challenge. But the second phrase is much different, brand awareness is a key for project like DaFatCat to gain trust from user.

Hopefully HackaTron and Marketing Campaigns could help us!

Yes it is, we are upgrading so users can deposit USDD directly and no need to worry about USDLP

We don’t call it betting because depositors lose nothing. You can deposit very little but have a chance to win big prize, no lose

OK so if you do not get a chance to win, will you get your deposit back?


Yeah exactly, you can get your deposit back!
