Inspiration

It started off as a joke to make the credit card version of 0mail, instead I made 0cards. Lets be real, credit card companies/banks pretend to care about privacy but still track everything.They offer “new” cards every year, but at the end of the day, every swipe is another breadcrumb for someone else to follow, use, and profit off. I wanted something better, something real. If I could burn and replace my card at will, why would I ever settle for the same old, leaky, one-size-fits-all account? That’s where 0cards really started. No more smoke and mirrors. Give me something I can control, kill, and regenerate on my terms.

What it does

0cards lets you spin up a new “0Card.” It’s a disposable, programmable digital card for any purchase, subscription, or one-off transaction. You set the rules, use it where you want, then burn it down when you’re done. It works with your wallet, your phone, and your rules, nobody else’s. No lingering trails. No permanent numbers. No metadata to scrape or sell. It’s privacy, finally done right.

How I built it

I started with the user flow. What if anyone could create a burner card in two clicks, set spend limits and expiration, then have it disappear with a tap? Every decision was filtered through: Does this add noise, or power? I used bolt's suggestion of Vite and Tailwind CSS for speed and visual sharpness, Whenever I caught myself drifting into “feature bloat” land, I would start over. Once I even duplicated the project and course corrected the vision. Frustration was constant, especially trying to get the minimal, elite look with just enough personality to stand out in a sea of fintech sameness.

Challenges I ran into

• Overthinking “privacy” versus actual utility. Every time I tried to bolt on new features, it diluted the whole point. Burn, use, vanish.
• Fighting with design tools and AI image generators to get icons that didn’t look like every other SaaS startup in 2025.
• Fighting with Supabase to set up the correct RLS to collect emails for those interested.
• Making the experience feel real and not just a Figma or AI pipe dream. The urge to keep adding more, when I knew the answer was always less.
• Most importantly racing against Time. ## Accomplishments that I'm proud of
• Actually shipped a working, live demo that nails the core concept: generate, use, burn.
• Built a visual and brand system that is instantly recognizable, matte, minimal, and unapologetically different.
• Never compromised on clarity, even when it meant killing features I secretly loved.
• Created something that feels new in an industry obsessed with sameness. ## What I learned
• Stay true to your vision and do not be afraid to pivot when needed.
  
• Don't let technology or tools stop you and utilize 3rd party AI to help you solve your issue. ## What's next for 0cards Build a secure backend to actually generate and destroy real burner cards. No more just UI.
• Integrate with Apple Pay and Google Pay so users can truly go invisible in daily life.
• Open up private beta to hackers, privacy maxis, and anyone sick of being surveilled.
• Push the programmable logic even further. One day, users will be able to automate their entire spend profile, not just burn cards.
• Keep refining. Less fluff, more power.
