You might know it as a tanda.
We know it starts with your people.
A group puts in the same amount each round. Each round, one person receives the pot. Everyone keeps contributing until everyone has had a turn.
Cointa brings that rhythm into one shared view: who’s paid, what’s next, and when your turn comes.

No. Cointa is currently an interactive product prototype. All balances, contributions, payouts, USDC amounts, and ID checks are simulated. Don’t use it to save, invest, or send funds.
A tanda is a rotating savings circle. Members contribute the same amount each round, and one member receives the combined pot. The cycle continues until everyone has received a turn. Cointa is inspired by this familiar community tradition.
No wallet is needed for the demo. Cointa shows dollar amounts and a USDC design preview, but no real crypto, exchange, network fees, or smart contracts are connected.
A member’s join number stays fixed based on when they enter the group. The leader’s wheel assigns a separate, random payout turn to each member. Everyone receives exactly one turn.
The iPhone prototype is being prepared for invitation-based TestFlight testing. This website’s pocket demo is available right now. When you receive a TestFlight invitation, use the app’s separate fictional demo entry to explore without SMS or an account.
The iPhone app includes a separate phone sign-in path using Clerk development authentication. The fictional demo does not require it. This website does not collect phone numbers or sign you into the app.
