Picture this

Who it is for

Nia runs a small streetwear label. Each piece ships with an NFC tag tied to an onchain record. Every owner can add a photo and a short story when it changes hands, so a resold hoodie arrives with three chapters: the launch night, a festival summer, a trip to Lagos. Provenance becomes the reason to buy secondhand.

Why it is new

What exists today, and what this does differently

What is new

Moves provenance from brand-authored ownership logs to an owner-written memory chain, where each holder adds a chapter only while they hold the item.

Closest things out there

MarketMaker (Intertrust), SmartLinks and Coachtopia NFC passports track authenticity, ownership and lifecycle events, but those records come from the brand. I found none that let each owner add their own story.

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.

How it earns for you

Owners read and write chapters for free. Labels pay per tagged item for a first drop or monthly for unlimited items, featured chapters, the Friday digest and moderation, and larger brands pay for resale partner scans and authentication exports.

The pitch, ready

Every piece carries the story of every life it lived, written by whoever wore it.

Problem: The moment a garment sells, its story is lost, and secondhand buyers cannot tell where a piece has been or whether it is real.

Solution: Signed NFC chips link each piece to a tap page. Only the current holder can write one chapter, sealed on Base when it changes hands, and copied tags show as not verified.

Why now: Resale is a mainstream channel, signed NFC chips cost about a dollar, and L2 gas makes a chapter cost about a cent.

Market: Independent streetwear labels, vintage and resale shops, and brands running circular programmes.

The ask: A pilot with three independent labels and two vintage shops.

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

For hackathons and demo days

Your 2 minute demo

Home: meet Nia in a Peckham railway arch on launch night.
Drop: tag sixty hoodies, hit the plans sheet and pay per item in USDC.
Handoffs: Tomás releases #031 to Kemi; a copied tag shows not verified.
#031: Kemi writes chapter 4 in Lagos and shares it.
Friday: pick the chapter of the week and feature it.
Owner Agent: the double claim and the copied link, both fixed.
Owner Revenue and Labels: change the Label price, decline a replica seller.
Owner Growth and Roadmap: run a swap night, then request resale partners.

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

Small labels and vintage sellers lose touch with every piece the moment it sells, and secondhand buyers cannot tell where a piece has been or whether it is real. The memories people attach to clothes vanish at each resale.

What exists and what is new

Brand provenance passports already exist: MarketMaker (Intertrust), SmartLinks and Coachtopia NFC passports track authenticity, ownership and lifecycle events. In those, the record is written by the brand. What is new here is narrower: each owner writes their own chapter, and only while they hold the item, so the history is a chain of owner-written memories rather than a brand log. Research did not find an existing product doing that; the NFC and onchain registry parts are not new.

The data it runs on

Per item: a registry entry (item id, brand, chip public key), the current holder, handoff signatures, and per chapter a text hash, author address and timestamp. Chapter text and photos are stored on IPFS and linked. No buyer names, addresses or prices are recorded.

1.The mission

Let the things we wear carry the stories of the people who wore them, written by those people.

2.Why people can't resist it

Tap the hem Any phone can read a piece's past lives in a second, no app or wallet needed to read.

Your chapter stays Sell it on and what you wrote travels with it, signed by you, forever readable by the next owner.

Friday chapters The label gets a weekly digest of new chapters on its pieces around the world, and can ask owners to feature the best ones.

3.How it works for real

Signed NFC chips: Chips such as NTAG 424 DNA produce a fresh signed counter on every tap (SUN messages), so a copied link or screenshot cannot pass as the real piece. Plain stickers are cheaper but cannot prove authenticity.

Item registry: A registry contract on Base (or Polygon or Solana) records each item, its chip key and its current holder. The brand admin tags items in bulk.

Handoff: The current holder releases the item to the next owner's address, or the claim opens after 7 days with no reply. Embedded wallets (Privy) mean owners need no crypto knowledge.

Chapters: Only the current holder can post one chapter per holding period: text up to the brand's limit plus one photo on IPFS. The chain stores the hash, the author and the time.

Tap page: A server checks the chip signature, then renders the chapters. Reading is public and needs no wallet.

Helper agent: Drafts chapter 1 for the brand to approve, flags spam and listings that reuse old tap counters, and writes the Friday digest. It never contacts owners or sellers without the brand's approval.

4.Cost per use and pricing

Signed chips cost roughly $0.80 to $1.50 each in small runs; plain stickers about $0.10 to $0.20. Registering an item on Base is a fraction of a cent to a few cents in gas, and a chapter is about a cent, often sponsored by the brand through a paymaster. IPFS pinning for a photo is well under a cent a month. Hosting and the tap page run about $20 to $40 a month for a small label. A 60 piece drop: about $72 in chips, under $5 in gas.

Per item $2 per tagged item

For a first drop. Includes registry, tap page and handoff for that item's life.

Label $200 a month

Unlimited items, brand page of featured chapters, Friday digest and spam moderation.

Larger brand $1,200 a month

Limited lines, resale partner intake scans, export of provenance for authentication.

5.Growth loop

Every resale puts a tap page in front of a new owner who sees the label's name and earlier chapters. Resale shops that scan tags at intake become a channel, and the best chapters featured on the label's site pull buyers toward pieces with a past.

6.Risks and guardrails

Tags and washing: Many sewn or woven tags survive washing, but test the exact tag through several washes before a full run.

Clones: Plain stickers can be copied. Use signed chips for anything where authenticity matters, and say clearly what plain tags cannot prove.

Spam and abuse: An open pen invites spam. Default to holder-only writing, add a report button and let the brand hide chapters without deleting the onchain hash.

Privacy: Owners may write things they later regret. Text lives off chain so it can be hidden from the tap page; only a hash stays. Never record buyer names, addresses or prices.

Resale value: Stories may help some pieces sell. The app must never promise higher resale prices.

8.Where this is going

Now
One label, sixty hoodies, each carrying the chapters of the people who wore it.
Next
Resale shops and tailors add repair and alteration chapters, so a piece shows how it was cared for.
Later
Vintage dealers tag old pieces and invite past owners to write their chapters back in.
The world it builds
Clothes that are kept and passed on because they carry something worth keeping.

OWNER PLAYBOOK

Own it, then chart your voyage

Nine routes from one vessel. Tap a port to open its chart.

Why own Stitch Story

Stitch Story ties each garment to an NFC tag and an onchain record, so every owner can add a photo and a short chapter when it changes hands. If a brand uses a third party provenance platform, that platform owns the item registry and the resale story. Own it, and the registry, the tap pages and the growing archive of stories behind every piece belong to your label, deployed from your wallet.
