Why it is new

What exists today, and what this does differently

What is new

Pieces exist in prototypes; a live street library with contract-held deposits was not found.

Closest things out there

BringBack (Monad hackathon) uses refundable onchain bonds for lending items, a University of Turin prototype tokenises a Library of Things, and Borrow (Berlin) holds offchain deposits.

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 pitch, ready

Lend the ladder, the drill, the tent: a street library of things with deposits held by contract.

Problem: Streets own the same few tools many times over and lack the one thing someone needs this weekend, because nobody wants to chase a ladder or argue about a snapped tent pole.

Solution: Neighbours list what they can lend. A small USDC deposit is held by an escrow contract while borrowed, refunded on return, split only by a neighbour vote, and each good return writes a lending history attestation.

Why now: Embedded wallets hide seed phrases, card on-ramps cover neighbours without crypto, and L2 gas makes a deposit hold cost a cent.

Market: Street groups, neighbourhood organisers, housing associations and councils with waste and sharing goals.

The ask: A pilot with five Leicester streets and one housing group.

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

For hackathons and demo days

Your 2 minute demo

Home: meet Priya, whose street owns twelve drills and no pressure washer.
Board: borrow Tomasz's pressure washer and list a camping stove.
Borrow: $25 held by contract, returned on time, or a neighbour vote on a snapped nozzle.
Street: lending chains grow with every good return.
Sunday: answer a wish, hit the Neighbourhood paywall for SMS digests and pay in USDC.
Owner Agent: the landline reminder and the photo judgement, both fixed.
Owner Revenue and Streets: change the Neighbourhood price, decline a hire shop adding fees.
Owner Growth and Roadmap: run a garage open day, then request the neighbourhood toolkit.

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

Most streets own the same few tools many times over and lack the one thing someone needs this weekend. Neighbours would lend, but nobody wants to chase a ladder or argue about a snapped tent pole, so the drill stays in the shed and the borrower buys another.

What exists and what is new

Pieces of this exist. BringBack, a Monad hackathon project, uses refundable onchain bonds for lending items; a University of Turin research prototype tokenises a Library of Things; Borrow in Berlin runs a lending service with offchain deposits; and many towns run physical Libraries of Things. Research verdict: rare, medium novelty. What this app adds is a ready-to-run street version: a catalogue scoped to a small radius, a USDC deposit held by contract while an item is out, damage settled by a small random neighbour vote, and a lending history that makes good lenders visibly trusted.

The data it runs on

Item listings (name, photo, owner, deposit size) and chat stay offchain in the app database. Onchain: deposit holds, refunds, vote-based splits and a lending-history attestation per good return, all keyed to wallet addresses, never names or door numbers.

1.The mission

Make borrowing from a neighbour easier than buying, so a street owns less and trusts more.

2.Why people can't resist it

The thing you need is 190 m away A wish gets matched to a real neighbour in seconds, which beats a shop trip and feels good.

Trust you can see Every good return adds a link to the lender's and borrower's chain. People like being the trusted one on the street.

No awkward money talk The deposit sits in a contract and damage goes to a neighbour vote, so nobody has to ask a friend for money.

3.How it works for real

Sign in and wallets: Email or phone sign-in with an embedded wallet (for example Privy) so neighbours never see a seed phrase. Deposits in USDC on Base, Polygon or Celo, chosen by the owner.

Deposit escrow contract: A small audited escrow: hold on borrow, refund on the lender's confirmation or after the due date plus a grace window, split only by a vote result. No admin withdraw.

Neighbour vote: A claim picks 2 to 5 voters at random from members with 3 or more good returns, excluding both parties. The contract settles to the majority outcome, capped at the deposit.

Lending history: Each good return writes an attestation (for example with EAS) linking lender and borrower addresses, readable as a public reputation chain.

Helper agent: A small model (for example a Haiku or GPT mini class model via OpenRouter) matches wishes to listings, writes reminders and the Sunday digest. It never decides damage.

Notifications: Web push, SMS or a WhatsApp business number for due-date reminders, with a confirmed mobile required at listing.

Fiat on-ramp: Card to USDC through an on-ramp provider for neighbours who do not hold crypto, with deposits shown in local currency.

4.Cost per use and pricing

Per loan on Base: hold plus refund is two small transactions, typically well under $0.02 together at recent Base fees, sponsorable by the owner. Agent matching and reminders use a few thousand tokens on a small model, around $0.001 per loan. A street with 140 loans a month costs roughly $3 to $6 in gas and model use plus hosting and SMS.

Street Free

One street, up to 50 homes, deposits and votes included. Owner covers gas from a small pot.

Neighbourhood $9 per month

Several streets, custom deposit rules, the Sunday digest by SMS and an organiser dashboard.

Council or housing group $149 per month

Many areas, insurance partner hooks, reporting on items shared and purchases avoided.

5.Growth loop

Every wish posted in the street group chat is a natural invite: the answer is a link to the item. Streets that run well get copied by the next street over, and the Sunday digest keeps lenders listing new things.

6.Risks and guardrails

Injury and liability: A borrowed ladder or washer can hurt someone. Show safety notes on risky items, require acceptance at borrow, and do not position the app as an insurer.

Deposit law and money handling: Holding deposits may trigger rules in some places. Keep amounts small, keep funds in a non-custodial contract, and take local advice before launch.

Unfair votes: Friends can vote for friends. Random selection, exclusions, a deposit cap and a visible vote history keep it modest.

Privacy: Door numbers and names never go onchain. Reputation links use addresses, and members can leave and hide their history.

Contract bugs: An escrow bug can lock deposits. Keep the contract tiny, audited and time-limited, with automatic refunds after a deadline.

8.Where this is going

Now
One street shares its ladders, tents and drills with deposits held by contract.
Next
Neighbourhoods link libraries, so a wish can reach three streets and a community hall.
Later
Lending history becomes a portable reference: proof that you return things, useful for renting, volunteering and joining new groups.
The world it changes
Towns buy fewer duplicate things, and trust between neighbours becomes something you can build and show.

Costs and tools are estimates at the time of writing. General information only, not legal or financial advice.

Why own Library of Things

Library of Things lets a street or building share ladders, drills and tents, with a small refundable USDC deposit held by contract while an item is out. If you own it, the lending network, the trust history and any small fees are yours, not a rental startup's. You become the person who made your street more generous.

What’s stopping you?

“I can't code.”

You run it from an admin screen: approve members, add item categories, set deposit sizes. DEPLOYR deploys it from your wallet.

“What if something gets broken or stolen?”

The deposit is there for that. Set it close to the item's value for expensive things, and let lenders choose who can borrow. Be clear in the rules that it is neighbours sharing, not insurance.

“My neighbours are not into crypto.”

Most will not care what chain it runs on. Help them set up a simple wallet once, keep deposits small, and show them it works with one ladder first.

“Is it really mine?”

Yes. The contract sits on your wallet and any small fees route there. Deposits are held by the contract and returned to borrowers.

“Could this make money at all?”

Modestly at street level. Real income comes from running it for many buildings, councils or housing groups. Treat the street as the proof, not the business.

The million-dollar ladder

Neighbourhoods use it free or for a small fee; the owner earns from housing associations, co working spaces, councils and campuses that pay a monthly plan to run their own library. About $1M a year is a target, not a promise.
