Chama, stokvel, susu, mukando, esusu, pardner, sou-sou — the same institution under different names, run for generations on trust and a notebook. Rounds keeps the trust and replaces the notebook with a contract that cannot forget.
Illustrative Round. Coynitt has not yet opened to the public.
Every Round is a contract on Coinbase Base L2. The rules are agreed once, at creation, and then enforced without anybody having to chase anybody.
Each member authorises the schedule once. The contract collects on the date, so no one is texting reminders on a Sunday night.
Payout order is drawn by the contract when the Round is created and published to every member. It cannot be quietly reordered later.
Each release is written on-chain with amount, recipient and date. Eleven years of history, readable by anyone in the circle.
Contributions are held by the contract, not by an organiser's personal account, until the cycle completes.
A missed contribution is flagged to the circle immediately, and the rules the group chose — grace period, cover from the pot, or removal — apply automatically.
A member who leaves mid-rotation is settled against what they have paid in, on terms the group agreed at creation.
Set the amount, the cadence, the size and the default rules.
Members join by link and each accepts the same terms.
The contract randomises the payout order and publishes it.
Contributions collect automatically each cycle, cross-border included.
The pot releases to whoever the order says, same day.
The rotation completes, the history stays, the group can restart in one tap.
The Kiambu cousins have run the same rotation for eleven years: eight people, CAD 150 a fortnight, whoever's turn it is takes the pot. It worked, and it also produced an annual argument, two missed contributions nobody could prove, and a spreadsheet only one aunt could read.
On Rounds the same rotation costs 1% of each payout, settles the same afternoon, and shows all eleven years of it to anyone in the circle who asks.
An illustrative circle, not a customer record.
Contributing to a Round is free. We take 1% when a payout is released, capped at CAD 25 per payout. Nothing for creating a Round, nothing for inviting members, nothing monthly, and no charge if a Round is dissolved before its first cycle.
Full pricing →No. A Round can mix members in Canada, the UK, South Africa, Zimbabwe and the other launch corridors. Each contributes in their own currency at the disclosed rate.
Nobody. The contract draws it at creation and publishes it to every member. That is the point.
The group picks the rule when the Round is created: a grace period, cover from the pot, or removal with settlement. Whatever was chosen applies automatically and visibly.
Contributions sit in the Round's contract until the cycle releases them. We do not lend against them and we cannot reorder a payout.
Yes. Name the Round whatever your family calls it — the app only calls the format a Round.
The history stays available and the group can restart with the same members and terms in one tap, with a fresh random order.
Not yet. Rounds contracts are deployed on testnet and Coynitt's FINTRAC MSB registration is Approval Pending. Join the waitlist and we will email your circle the day it opens.
