Who it is for

Why it is new

What exists today, and what this does differently

What is new

No product found unlocking a local treasury only after verified in-person presence.

Closest things out there

POAP check-ins and CityDAO exist, but no treasury found that gates proposals on physical neighbour attendance.

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

Neighbours never pay to take part. Street organizers pay a small monthly plan and housing associations pay to run many streets. Street pots always belong to the street.

No fee on pot money. Gas for shares and payments on Base is a few cents a street per month and can be sponsored.

For investors and grant reviewers

The pitch, ready

A neighbourhood treasury where proposals unlock only after enough real neighbours physically show up.

Problem: Street funds stall because online votes are easy to fake and nobody trusts who spent what, so small fixes like a broken swing wait for years.

Solution: Homes pay a small monthly share into a street multisig. Ideas pass only when enough households scan a rotating QR at the lamppost in person, and every payment is published with its turnout and invoice.

Why now: Cheap transactions on Base, Celo and Polygon and phones with location make in person presence a practical, low cost vote.

Market: Residents' streets and buildings, housing associations, and councils that want to match community funds.

The ask: Pilot partners: two housing associations and one council grant programme, plus public goods funding rounds.

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

For hackathons and demo days

Your 2 minute demo

Home: meet Lupita, 68, on Calle Jalapa in Colonia Roma.
Pot: pay October's share and read the street balance.
Ideas: the swing is up for Saturday; new ideas sit behind the Organizer plan.
Meet: check in at the lamppost and watch 24 homes reach quorum; try the remote wallets and the QR photo.
Receipts: the swing payment, the lanterns and the board gate.
Owner Agent: the photographed QR and the neighbour vouch fix.
Owner Revenue: change the Organizer price and preview the Plans sheet.
Owner Growth and Roadmap: throw a block party night, then request the association desk.

Many hackathons require code written at the event. See the Regatta Boardfor each race's rule.

BLUEPRINT

Why it matters and how it really works

The need

Street and building groups collect money in chats and then argue about who decides. Online polls get gamed by people who never live there, and the same three people end up holding the cash with no receipts.

What exists and what is new

Presence proofs exist: POAP issues attendance badges from QR and event codes, and CityDAO experimented with land-based community governance. Multisig treasuries like Safe are standard. Our research found no product that gates a local treasury's spending proposals on neighbours physically checking in at the spot. Research verdict: fresh, high novelty, though each building block is well known.

The data it runs on

Member list (private), monthly contributions, rotating QR codes and short-lived check-in tokens, phone location within a radius at check-in, neighbour vouches, proposals with quotes and invoice photos, signer approvals and releases.

1.The mission

Let the people who actually live somewhere decide together, in person, how their shared money gets spent.

2.Why people can't resist it

Your showing up is your vote No proxies and no strangers. Being at the lamppost on Saturday is what gives you a say.

Receipts on the lamppost Every release links the passed proposal, the presence count and the invoice photo. Anyone on the street can check.

A reason to meet Meetings decide real things, so people come. One lantern lights up for every meeting you attend.

3.How it works for real

Wallets: Privy embedded wallets for each household on Base (or Celo for low-fee mobile use). No seed phrases; sign in with phone or email.

Street treasury: A Safe multisig (for example 3 of 5 elected signers) holds USDC. A guard module only allows transfers that match a passed proposal ID and amount.

Contributions: Monthly pulls via a fiat on-ramp or a manual USDC deposit; each household's paid months are tracked offchain and summarised onchain as a running total.

Presence check-in: A screen or e-ink display on the spot shows a QR that rotates every 10 to 120 seconds. Scanning signs a short-lived token plus a coarse location check. Optional vouch: two present members confirm one more, capped per meeting.

Proposals and quorum: A small contract records each proposal, the Merkle root of present households and the quorum result. Names and locations never go onchain.

Helper agent: A cheap model tier (for example a small Claude Haiku class model via OpenRouter) drafts proposal summaries in plain language and flags suspicious check-in patterns. It cannot sign or move money.

Notifications: WhatsApp or SMS reminders for meetings, results and releases, plus a printable receipt for the noticeboard.

4.Cost per use and pricing

Per meeting: Base gas for a proposal, a presence root and a release is typically a few cents in total. The helper model costs well under one cent per proposal summary. Example month for a 40-home street: about $1 in gas, under $1 in model calls, $5 to $10 in SMS, $10 in hosting. Roughly $20 a month, small next to a pot of MXN 3,800 (about $220).

Street Free up to 25 homes

One treasury, rotating QR, monthly meetings, receipts.

Neighbourhood $12 a month

Up to 150 homes, several meeting spots, SMS reminders, printable receipts and vouch rules.

Association $49 a month

Multiple streets or buildings, an e-ink lamppost display kit, exports for accountants, custom quorum rules.

5.Growth loop

Every fixed swing comes with a printed receipt and a QR on the lamppost. Passers-by from the next street see it, and the share card goes into other building chats. Associations onboard streets one at a time.

6.Risks and guardrails

Exclusion: Elderly, disabled or shift-working neighbours may not be able to attend. Offer vouches, a second meeting slot and a delegated presence rule decided by the street.

Location spoofing: GPS can be faked. Rotating codes, short windows and vouch caps raise the cost, but it is not perfect; large sums should need higher quorum.

Signer collusion: Signers could refuse to release or try to misuse funds. The guard module limits transfers to passed proposals, and signers can be replaced by a quorum vote.

Legal status: Collective funds may need a registered association or local tax treatment. The owner should check local rules before collecting money.

Privacy: Presence data reveals who is home when. Only a root goes onchain; raw check-ins are deleted after the meeting.

8.Where this is going

Now
One street, one lamppost, one pot, spent only when neighbours show up.
Next
Buildings, markets and school parent groups run their own pots with the same presence rules.
Later
City councils match street pots that keep strong turnout and clean receipts.
The world it builds
Small public money gets decided by the people who live with the results, face to face.

Why own Block Party

Shared money in a neighbourhood usually lives in one person's bank account and a lot of trust. Own Block Party and you run the treasury where decisions come from neighbours who actually showed up, from your wallet and brand. The neighbourhoods, the spending log and the trust are yours.

What’s stopping you?

“My neighbours don't use crypto.”

Most won't at first. Use a simple wallet, help the first five set up in person, and keep the contribution small.

“Who is liable for the money?”

Talk to your group about who signs, and check local rules for community funds. The multisig makes spending visible, not legally simple.

“I can't code.”

You do not need to. Block Party arrives working, deployed from your own wallet with a written guide for every step. You will click, paste and fill in names. If you ever want a change you cannot make, the custom option or a freelancer can handle it, but the first launch needs no code.

“Is it really mine?”

Yes. The contract is deployed from your wallet on Base, the code sits in your own git repo, and the name and brand are yours. DEPLOYR does not hold your keys or take a cut of what Block Party earns. If you stop paying anyone tomorrow, the app keeps running on your wallet.

“What if nobody uses Block Party?”

That is the most likely early outcome, and it is fixable. The paths below start with you as the first user, then ten real neighbourhoods, tenant groups and street committees you can name today. If ten people you message do not care after you have shown it to them, you have learned something useful in a week instead of a year.
