🤝 Values & How we work?

The entire crypto space doesn’t just move fast but is constantly accelerating
It’s hard building a DeFi product — it’s 24/7, 365 days a year, markets do not close, the ground beneath you can shift, assumptions can and do fail & risk of burning out is real

• We take our product + brand very seriously
  

  • If we see even a small flaw in our product, we always ask ourselves – Why isn’t this perfect?

  • All members have perpetual autonomy to fix anything broken that we notice, and we do not wait for someone else to tell us what to do
    

• Take extreme ownership of everything we do

  • If the team fails, everyone fails, so prioritize and execute
    

  • We think long-term, set big goals, and communicate with clear directions and goals to achieve them
    Everyone must understand not just what they’re doing but also why they are doing it
    

  • No Egos, lead by example, and mutual accountability
    

• Strive for clear and simple communication – this is easier said than done but communicating the “why” of an issue is equally important as the “what
  ”

• All meetings have an agenda, with outcomes clearly defined as tasks and call-to-actions
  

• Prioritize all tasks by – what is more important for our users without compromising on any of the above goals
