THE NAME
chama
A group of people who save together, and show up for each other.
Long before apps, neighbors pooled what they had and took turns receiving it. No bank. No platform. People who kept their word.
- Open today
- Savings circles. Everyone locks an equal share, and everyone’s exact sats come back.
- Coming next
- Turns. Each round, one member collects the whole pot, until everyone has.
- Every round
- All or nothing. If even one seat doesn’t lock in time, the round refunds automatically and everyone’s exact sats come back.
BITCOIN, OUT IN THE WORLD
For the everyday.
Week after week.
One way to trade.
So many reasons to.
01
Save together
A circle with people you trust.
02
Swap sats and cash
Food, fares, and everyday cash.
03
Pay a bill
Rent, utilities, care, and obligations.
04
Buy and sell
Groceries, bicycles, cars, even a home.
THE SOFTWARE STEPS BACK
Your trade.
Never our money.
Chama connects the people and the agreement. It cannot take your sats or settle a trade on its own.
A closer look at the safeguardsThree people. It takes any two.
Chama has no vote.
Two signatures. One settlement.
Buyer, seller, and arbiter each have a role. Two of the three must agree to settle an escrow trade.
The terms come first.
Know the amount, the conditions, and the arbiter before you lock sats. Start in the sandbox to learn the flow.
Open for anyone to inspect.
