Who it is for

Twenty ride-share drivers in Nairobi chip in $5 a month. When Otieno's car breaks down he requests $200, three members approve within an hour, and USDC lands. No insurer, no promised returns, just each other.

Why it is new

What exists today, and what this does differently

What is new

The mechanic exists in prototypes; a maintained small-group product was not found.

Closest things out there

ChipIn (hackathon), help a fren (open source) and aidDAO prototype group emergency funds with voted payouts; none confirmed live.

Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.

The money path, built in

How it earns for you

Running a pool is free. Chairs pay for Pool Plus per pool, associations pay monthly for many pools, and the owner can set a small service fee on payouts shown on every receipt. Plan money never passes through the pool.

PoolFreeUp to 25 members, asks and votes, ledger, receipts, reminders
Pool Plus$9 a month per poolTop up circles, Friday WhatsApp digest, yearly report, up to 60 members
Association$49 a monthUp to 10 pools, chair dashboard, branded share cards, member transfer between pools

Optional service fee on payouts (0%, 0.5% or 1%) set by the owner. Gas on Celo is under one cent and can be sponsored.

Prices are yours to set. Illustrative, not a promise of income.

How it spreads

  • Stage launch evenings: a chair whose pool paid out brings the next stage over
  • Payout share card that names the group, not the app
  • Members invite drivers they trust, with a waiting period that keeps it fair
  • Chair to chair referrals worth a free month of Pool Plus for both pools

The pitch, ready

A rainy day fund a small group runs itself: chip in monthly, vote fast, USDC lands the same hour.

Problem: Gig drivers, traders and small crews live one breakdown or hospital bill from losing a week of income. Insurance rarely covers them and group funds run on a treasurer's notebook and trust.

Solution: A shared pool contract with a cap, tiered approvals, a waiting period and photo fingerprints. Members ask, friends approve with their wallets, and a steward agent reminds and tallies but never moves money.

Why now: Phone number wallets, near zero gas on Celo and Base, and USDC to mobile money off ramps make a group fund practical for people who never touch crypto.

Market: Ride share and boda drivers, market traders, church and savings groups, and the associations that organise them across East and West Africa and beyond.

The ask: Pilot partners: one drivers association and one off ramp partner, plus grant funding from public goods and financial inclusion rounds.

Funding is never guaranteed. Check each program's rules.

For hackathons and demo days

Your 2 minute demo

  1. Home: meet Otieno, 34, Nairobi. His clutch died at 7 PM and the pool is his umbrella.
  2. Ask: pick car repair, $200, add the garage quote photo and see the rules preview.
  3. Ask: send it, watch three approvals arrive and USDC land, cashed out to M-Pesa.
  4. Vote: approve Wanjiru's over cap ask, see Brian held by the waiting period and Kevin's repeat photo flagged quietly.
  5. Pool: show the receipt, what is onchain and what stays with members, then the gated yearly report.
  6. Owner Rules: change the cap or waiting period and see the same asks land differently.
  7. Owner Steward: the 6 AM reminder failure and the Friday 7 PM fix.
  8. Owner Revenue and Roadmap: edit the Pool Plus price, preview the Plans sheet, request the v2 build.

BLUEPRINT

Why it matters and how it really works

The need

Gig drivers, market traders and small crews live one breakdown or hospital bill away from losing a week of income. Formal insurance rarely covers them, chamas and merry go rounds run on trust and a treasurer's notebook, and when money is short it is the treasurer who carries the stress and the suspicion.

What exists and what is new

The mechanic exists in prototypes, not as a maintained product. ChipIn (a hackathon project), help a fren (open source) and the aidDAO prototype all show group emergency funds with voted payouts, and none was confirmed live. Research verdict: rare, medium novelty. What this app adds is the everyday packaging for one small group: tiered approval thresholds, a cap per request, a waiting period for new members, a voluntary top up circle when an ask is over the cap, proof photo hashing against repeat claims, and a steward agent that reminds and tallies but never decides.

The data it runs on

Monthly contributions and payouts in USDC on the chosen chain, member wallets and the membership snapshot taken when each request opens, approval signatures, request amounts and the cap rule used, hashes of proof photos. Reasons, photos and phone numbers stay in group storage visible to members only.

1.The mission

Give any small group a rainy day fund it can run itself, quickly and fairly, without an insurer or a single treasurer holding the bag.

2.Why people can't resist it

Paid within the hour A real ask approved by friends lands as USDC the same evening and cashes out to mobile money. People tell that story at the stage.

Umbrella Friday A one glance weekly check: pool balance, who is covered, your on time streak, and who the pool helped this month.

Rules you chose together Cap, thresholds and waiting period are voted in by the group, so a held request feels like the group's rule, not someone's judgement.

3.How it works for real

Wallets: Members sign in with an embedded wallet (for example Privy) tied to a phone number, so nobody needs a seed phrase. Celo is the default for low fees and mobile money off ramps, with Base or Polygon as options.

Pool contract: A small audited Safe based pool with a module that enforces the cap per request, approval thresholds by amount, the new member waiting period and a membership snapshot per request. Payouts need the configured number of member signatures.

Requests and votes: A request stores amount, reason category and a proof photo hash onchain. Votes are wallet signatures collected offchain and submitted in one transaction when the threshold is met.

Steward agent: A scheduled agent on a small model tier (for example Claude Haiku) sends reminders, tallies votes, flags repeat proof hashes and drafts the Friday digest. It holds no keys that can move funds.

Notifications: WhatsApp or SMS through a messaging API for reminders, requests and payout receipts, with times the group chooses.

Cash out: USDC to local currency through a licensed off ramp partner in each country, for example to M-Pesa in Kenya. The app does not hold customer funds itself.

Indexer: A light indexer reads pool events to build the ledger, the balance chart and the yearly report.

4.Cost per use and pricing

On Celo a contribution or payout costs well under one cent in gas. The steward agent uses roughly 2,000 tokens per digest or tally on a small model tier, about $0.002 to $0.01 each. Messaging is the main cost at about $0.005 to $0.05 per message depending on country and channel. A 20 member pool with weekly digests runs about $3 to $6 a month all in, before off ramp fees which the member pays at cash out.

Circle Free up to 12 members
One pool, fixed rules, monthly reminders.
Stage $9 a month per pool
Up to 50 members, custom thresholds and caps, top up circles, WhatsApp digests, yearly report.
Federation $49 a month
For associations running many pools: shared dashboard, chair rotation, exportable records for their own auditors.

5.Growth loop

Every payout is a story people repeat at the stage, and the share card names the group, not the app. New members join existing pools by invite, and drivers who move routes start new pools with the same rules. Associations of drivers, traders and churches run pools for their members.

6.Risks and guardrails

Not insurance: In many countries pooling against risk can fall under insurance or savings group rules. Keep pools small and member run, never promise payouts, and get local legal advice before marketing to the public.

Join, ask, leave: Waiting periods, caps and membership snapshots limit it. Overrides need a larger vote.

False claims: Proof photo hashes catch reuse. The group still has to trust each other; the app makes it visible, not impossible.

Pool runs dry: The app warns when the cap is large compared with monthly inflow and shows months of runway before every vote.

Privacy: Medical and family reasons stay offchain and visible only to members, deleted after 90 days by default.

Key loss: Embedded wallets with phone recovery, and the pool contract lets the group vote a lost member's replacement wallet in.

7.Build order

  1. Pool contract with cap, thresholds and waiting period on Celo testnet
  2. Phone sign in with embedded wallets and monthly USDC contribution
  3. Request with proof photo and member approvals
  4. Payout and one off ramp partner in one country
  5. Steward agent for reminders and tallies, WhatsApp digest
  6. Ledger view and yearly report

8.Where this is going

  1. Now
    One group of drivers covers each other for breakdowns and hospital deposits, paid within the hour.
  2. Next
    Associations run dozens of pools with shared rules, chair rotation and records their own auditors can check.
  3. Later
    Pools for traders, nurses and seasonal workers across East and West Africa, Latin America and South Asia, each tuned to its own risks.
  4. The world it builds
    Millions of informal workers with a safety net made of each other, transparent enough that nobody has to trust a single treasurer.

Why own Mutual Umbrella

Mutual Umbrella lets a small group pool a rainy day fund and vote quickly on emergency payouts to members. Owning it means the groups you serve trust your deployment, not an unknown app, and every contribution and vote is visible onchain. It is not insurance and promises no returns, it is people looking after each other with better tools.

What’s stopping you?

“I can't code.”

DEPLOYR deploys it from your wallet. You help groups set up: members, monthly amount, how many approvals a payout needs.

“Is this insurance? Is it legal?”

It is a mutual aid pool, not insurance, and you must say so plainly. Rules on pooled funds differ by country. Keep groups small and member run, never promise payouts or returns, and get local advice before running it at scale.

“What if someone abuses the fund?”

Groups set their own approval rules, like three members must approve. Payouts and votes are public to members. Start with groups who already know each other.

“Is it really mine?”

The app deployment is yours and fees route to your wallet. Each group's pool belongs to its members, not to you. That separation is the point.

“What if the pool runs dry?”

It can. Groups should set a payout cap and a waiting period for new members. Be honest that the fund only holds what members put in.

The million-dollar ladder

Groups use the app to run their own pools; the owner earns a small monthly fee per group for the tools, never a share of the pooled money. About $1M a year is a target, not a promise.
