Built for La Crypta Hackathons 2026

BitByBit

Parents create habits. Kids earn Bitcoin.

Earn sats. Build habits. Change lives.
A habit tracker powered by Bitcoin Lightning that rewards task completion with real sats.

How It Works

Four simple steps from task to sats

1

Fund a Wallet

A sponsor — parent, community, or yourself — loads sats into a Lightning wallet

2

Set Up Tasks

Create habits and daily tasks with sat rewards attached to each one

3

Get Reminded

AI bot sends Duolingo-style reminders. Motivational, persistent, fun.

4

Complete & Earn

Finish the task, get verified, receive sats instantly via Lightning

Real Use Cases

Not just another habit tracker — a tool that changes lives

Financial Education

Allowance 2.0 — Kids Stack Sats

Parents fund a Lightning wallet. Kids earn sats by completing chores and responsibilities. It's the modern allowance — digital, instant, and teaches financial literacy from day one.

  • Make the bed, do laundry, homework, wash the car
  • Kids learn to save, spend, and stack sats
  • Parents see everything — full transparency
  • Builds responsibility through real economic incentives
Community Health

Exercise & Earn — Healthier Communities

Community pools where members earn sats for working out. Inspired by real conversations at La Crypta about zapping people who exercise. Social accountability meets Lightning rewards.

  • Community funds a reward pool
  • Members earn sats for verified workouts
  • Integration with open-source fitness trackers (Nostr-based, self-hosted)
  • Nostr zaps for celebrating milestones together
