Rotating savings, kept honestly

A cash box that no one has to hold.

Unaudited, personal project — use at your own risk

Cherga currently runs on the Whitechain testnet only. The stablecoins in a circle are test tokens with no value — nothing here moves real money. Cherga is @zahumennov’s personal project, and comes with no support and no guarantees.

Need test tokens?
WBT, for gas

Every transaction costs a little WBT, Whitechain’s native gas token. Without it your wallet can’t send anything.

mUSD, to pay with

mUSD is Cherga’s test stablecoin — not a real asset, just a contract anyone can mint from. This sends 1000 mUSD to your connected wallet.

A fixed group of 2–20 people chip in the same amount on the same schedule, and each round the whole pool goes to one member — in turn, until everyone has received it exactly once. Whoever goes first borrowed at no interest. Whoever goes last lent at no interest. Nobody ends up ahead and nobody ends up behind.

People have run this for centuries — tanda in Mexico, susu in West Africa, hui in China, chit funds in India, pardna in Jamaica. Cherga is the same arrangement written as a smart contract, so the bookkeeping can’t be faked and no one has to be the treasurer.

This might not be for you

If your group is in one place and one currency, a shared spreadsheet and a jar will do the job better. If you’re looking for a return on money, this pays none — by design. If you don’t already know every person in the circle personally, close this page.

It might be for you

Friends spread across countries who can’t pass a box around. Groups who already hold stablecoins. People whose local currency loses value while they wait their turn.

How it works
Tap a step for detail

Five steps, then it’s over. Nothing renews and nothing runs in the background.

One person sets the terms.
Which stablecoin, how much each person pays per round, how many people are in the circle (2–20), how long a round lasts, and the date by which the circle has to be full. After the circle exists, none of it can be changed — not by the person who made it, not by anyone.
What it’s for

Nobody makes money here. That is the point.

A circle moves money around in time instead of growing it. You give up access to small amounts for a while and get one large amount when your turn comes — and someone else in the group gets the same deal, in a different month.

A lump sum, no lender
Going early is a loan from your friends at zero interest — no credit check, no bank, no collateral. You pay it back in the following rounds, in instalments you already agreed to.
Saving you actually keep up
Going late is saving with a deadline and an audience. Most people skip a solo savings plan; far fewer skip a payment their friends are waiting on.
No treasurer, no arguments
Nobody holds the box and nobody keeps the notebook. Who paid, who was short, who owes whom — all of it is on the chain, identical for everyone, and impossible to misremember.
