How a circle works

Five steps, then it repeats.

A chit is the oldest savings product India has: a group pays into a common pot every month, and every month one member takes the whole thing. Everyone takes it exactly once. It is a savings club and a credit line running on the same rails — and it has never had a ledger anyone could check.

  1. Form

    A group that already knows each other creates a circle and fixes the terms up front — size, monthly amount, duration, and what the admin takes. All of it is visible before anybody deposits.

  2. Fund

    Members pay in rupees. Set it up once and each month's due is collected on the same day automatically, or deposit by hand if you would rather stay hands-on. No wallet to top up, no token to buy, no gas to think about.

  3. Take

    One member takes the pot each month. Friendship mode assigns the month in advance; auction mode lets whoever needs it bid. Everyone takes exactly once.

  4. Repay

    From the month after you take, you pay interest on the pot until the circle closes. It does not come to us — it is credited back to every member, reducing what they owe.

  5. Close

    The last month settles and the final credits land. The circle's whole history stays on-chain — a clean record and a default both follow the member into the next one.

Two ways to run one

One contract, two traditions.

Families run chits differently, and both ways are correct. ManaCircle treats the difference as a mode on the same circle rather than a different product, so a group can run whichever one they already run offline.

Mode one

Friendship chit

The admin sets the order before the circle starts, and every member sees their month before depositing. When yours arrives you take the pot — no bidding, no choice.

Built for groups where the order is a social decision rather than a market one. Whoever needs money soonest goes first; the patient go last. Going last is the best seat in the circle: you pay no interest at all, and you collect everyone else's.

Because the early seats are the ones carrying real credit, they are the seats a group should assign carefully — that is the one judgement call this mode asks of you.

Mode two

Auction chit

Nothing is assigned. Each month, whoever needs money bids the amount they are willing to receive, under a ceiling the admin sets. The lowest bid takes the pot, and the discount they gave up is split across every member.

The rule that makes it work

Waiting is free. Never bid and you still get a pot at close, interest-free. So a bid only ever comes from genuine urgency — and urgency is the only thing this auction prices.

If nobody bids in a month, the pot parks in the reserves earning yield and is offered again. If nobody ever bids, the circle quietly becomes a group savings club that earned all year — the degenerate case is a good outcome, not a broken one.

The circle board

Everyone can see everything.

In an offline chit the register lives in the foreman's notebook. You find out about a missed payment when the pot comes up short, and a dispute is one person's word against another's. Here, every member watches the same board — who has paid, whose payment is retrying, who is inside the grace window. The same social pressure that keeps offline chits alive, with perfect information.

Kiran's payment did not go through on day 21. All nine other members saw it the day it happened, and they keep seeing it through the retry window and the grace period — long before it can become a default. If it does, that default is a permanent record. Members see each other by name inside their own circle; the chain underneath only ever sees an address.

What we're building

Transparency is the product.

Every other way to fix an informal savings circle starts by hiding something. We think the opposite is true: a chit works because the group is watching, and the group has never had a ledger good enough to watch with.

A board every member can read

Payment status, retries, grace countdowns, the reserve balance and what it has earned — live, for everyone in the circle, not just whoever keeps the notebook.

Two traditions, one contract

Friendship and auction chits are a mode flag on the same circle, so a group brings the version they already run rather than learning ours.

No wallet to learn

Sign in the way you would to any app — keys, gas and seed phrases are handled underneath. Dues are paid in rupees, collected automatically or deposited by hand, with retries and a grace window before anything counts against you.

Reputation that travels

Paying on time and defaulting are both permanent records attached to a member's account. Their history follows them into every circle they ever join.

No idle money

An offline chit's cash earns nothing between collection and payout. Here it sits in shared reserves in whitelisted lending markets, earning until the day it is paid out.

Invest & Grow

For people who want the saving without the circle: a monthly deposit on the same rail, withdrawable — principal and earnings — at any time, with no lock-in and no penalty.

Why Base

The chain has to disappear.

Nobody joins a chit fund because it is on-chain. The chain has to be invisible to the member and load-bearing underneath — which rules most of them out.

Accounts, not wallets

Smart accounts let someone join a circle without ever meeting a seed phrase, and let a monthly due be collected on a standing permission without anyone taking custody. Without that, none of the simplicity above survives contact with a real member.

Fees that round to nothing

A circle settles every month, for every member, for its whole life. Transaction cost has to be negligible or the model quietly stops working at small ticket sizes.

Where the users already are

Rupee onramps, consumer-grade account infrastructure, and mature lending markets for the reserves to sit in — all of it already on Base, none of it something we should be building ourselves.

Questions

The things people ask first.

What is a chit fund?

A group of people pay a fixed amount into a common pot every month, and each month one member takes the whole pot. Everyone takes it exactly once, so by the end everybody has put in the same and taken out the same — but the person who needed money in month one got it in month one. India has run them for generations, mostly on trust and a notebook.

What happens if someone stops paying?

The payment retries through the month, then a grace period starts — all of it visible on the board the whole time. If it still fails it becomes a default: the shortfall is shared by the remaining members, and the default is written against that member's account permanently. A circle itself can never go insolvent, because pots are only ever paid out of money already collected. Members who want zero default risk belong in a public circle, where the whole commitment is escrowed at join.

Do I have to bid?

Never. In auction mode, not bidding is a real strategy — the pots nobody claimed are handed out at close among the members who never took one, interest-free. In friendship mode there is no bidding at all; your month is set before the circle starts.

Who holds the money?

The contract. Not a foreman, not us. Idle funds sit in shared reserves and go only to whitelisted, blue-chip lending markets under per-market caps, with every rebalance publicly visible. The allocation role can move funds between those markets and nothing else — it can never withdraw. Adding a market sits behind a timelock, and emergency mode freezes allocation while leaving withdrawals open.

What do you charge?

A share of earnings — interest and yield — and nothing on principal. The admin fee is separate and belongs to whoever runs the circle: they set it, it is visible before you join, and it can be zero. That is the real difference from an offline chit, where the foreman's cut is fixed, opaque, and unavoidable.

Is the yield guaranteed?

No. Lending yield is variable and moves with the market. What the contract enforces is your right to withdraw — not a rate.

Do I need to know anything about crypto?

No. You can run an entire circle in rupees without ever touching a token, a wallet or a gas fee. Circles are priced, displayed and paid in ₹ because that is how the group thinks about the money. Underneath, settlement happens in USDC on Base and your account is a smart account — but that is our problem to handle, not something you should have to learn to save with your friends.

What is a public circle?

The same machine, for strangers. Instead of paying month by month, a joining member puts the full amount in up front and each month's due comes out of it — so default risk is zero by construction, which is what makes a chit between people who have never met safe. It ships after closed circles.
