Savings circle vaults the organizer holds, not you
Hundreds of millions of people save in circles - a tanda, a kameti, a pardner, an ayuuto, a paluwagan, a stokvel. Ten people put in $100 a month; each month one member takes the pot, in the order the group set at the start. Every app that tried to digitize this died the moment the company held the pooled money and the law treated it like a bank. A vault only the organizer controls removes that: the rules live in code, the schedule is enforced on-chain, and the people who built the software never touch the money.
What this enables
- →A product that doesn't die on contact with a money-transmitter license. Yahoo launched a savings-circle app in January 2018 and shut it down four months later. eMoneyPool worked on it for nine years and closed in 2019. PayPal killed its group money pools despite holding more licenses than almost anyone. Every one hit the same wall: the moment the company holds the pot, it needs a bank or money-transmitter license in every country it touches. A vault only the organizer controls means no company holds the pot, so no company needs a license for the pot.
- →The border-crossing circle that already exists, finally served. A nurse in Minneapolis runs a circle with her sister in London and her mother in Mogadishu - today on WhatsApp, cash, and trust. Remittance companies move $685B a year to these corridors, but only person-to-person. No product serves the group. The vault does, with licensed money companies handling the bank-to-digital-dollar conversion at each end.
- →A white-label rail for the companies that survived. Bloom Money (UK only), MoneyFellows (Egypt, 8.5M users, profitable, spent nine years and $13M trying a second country), Hakbah (Saudi Arabia, 1.2M users), Oraan (Pakistan) - each is locked out of the international version of its own product by its own single-country license. The offer: your users, your brand, your home license untouched; the international circle runs on a vault the organizer holds, so your company never touches that money. These companies become customers, not competitors.
- →A savings mode as well as a rotating one. The same vault can lock every member's contributions until a chosen date - for groups saving toward a holiday, a wedding, or Eid - not just rotate a pot each month.
- →Optional privacy that fits the law, not around it. Members may not want outsiders to see their balances or who belongs to the group. Starknet's privacy tools can hide balances and membership from the public while still disclosing to the licensed money companies exactly what regulation requires them to see. This makes the product better; it is not required.
What you build
An account that only the organizer controls, holding digital dollars, with the circle's rules encoded on-chain: the contribution schedule, the payout order the group agreed at the start, late-payment rules, exit rules, and automatic payout when a cycle closes. A second mode locks savings until a chosen date. Above it, an app that feels normal - sign in with email or a passkey, never a seed phrase, never a gas fee, never anything that looks like crypto. A member sees "our circle, 10 members, $100 a month, my payout comes in March." Starknet's account features (native account abstraction, session keys, paymaster-sponsored transactions) are what make that invisibility possible, and that is why this idea belongs here. Wire in licensed money companies for the bank-to-digital-dollar conversion and identity checks at both ends - UK↔Pakistan (Pakistan licensed such companies in 2025) and Gulf↔Philippines (licensed for years) are the two most workable first corridors.
The rules that keep it legal
These come from the ways past products died or got regulated. If you build this, treat them as fixed.
- →Never hold or move the money, and never be able to. No admin keys, no backup access, no ability to sweep a vault.
- →Charge flat software fees. Never a percentage of the pot; never fees that scale with the pooled amount.
- →Never let the platform pick the payout order. The group sets it when the circle starts. StepLadder (UK) picks winners by draw and needed a consumer-credit license for exactly that.
- →Invite-only, always. No public list of circles, no search, no matching strangers, no advertising individual circles. Circles are people who already know each other.
- →No bidding circles. Members bidding to receive the pot early by accepting less is a discount that works like interest between members - lending law then applies.
- →No yield on pooled money unless your own lawyers clear the design first. No sellable credits or play money that can convert to real money - several US states banned that pattern in 2025.
- →Block the countries that license the organizer. India (Chit Funds Act), Ghana (registers collectors), South Africa (currency controls block the international leg). This is a start, not a complete map - check every country you serve.
Why this isn't a neobank or a wallet
A neobank or a pooled-savings wallet holds customer funds - which is precisely the thing that forced eMoneyPool, Yahoo, and PayPal's money pools to shut down or acquire licenses. Here the company holds nothing and cannot: the pot lives in a vault the organizer alone controls. The software is plumbing, not a balance sheet.
Why this isn't a lending or a yield product
Nobody borrows and nobody pays interest - after ten months everyone has paid in $1,000 and received $1,000. There is no credit extended, no return promised, no bidding for early access. Removing those is what keeps it out of lending and securities regimes. This is not a prediction market, not a lending product, not a yield product, and not a bid to compete with the existing circle companies. It is the rail they adopt.

Private payroll and treasury disbursement at company scale
A payroll protocol where per-recipient amounts stay private from each other and from the public, but the payer can prove aggregate spend to auditors and each recipient can prove income for tax filings. The compliance model traditional payroll uses, brought onchain without a centralized intermediary.
