Building Totemo
Street-art gallery's operations and artist royalties inside an NFT platform
Totemo represents street artists in Tokyo, turns their walls into digital works and sells them to collectors it has invited. Its staff decide which artists join, which works go on sale and what each sale pays out. Aetsoft built the platform those decisions run on, from admitting an artist to paying the royalty.
Street art earns its makers nothing and is gone within months. Totemo photographs and animates the work with the artist, then sells it as a digital piece. A buyer is relying on Totemo having picked the artist and approved the work. A gallery makes those calls in a back room; here they had to be made in software. A staff member could publish for an artist who held no cryptocurrency, and neither of them paid to mint it.

ChallengeStreet art disappears and pays its makers nothing, and a photograph of a wall proves nothing about who painted it. Totemo needed a sellable object, a record of who made it that a buyer could rely on, and a commercial model that paid the artist on every sale. Running all three meant gallery operations: choosing artists, approving work, agreeing terms piece by piece. Most of its artists held no cryptocurrency.

SolutionAn NFT platform shaped to those operations. Totemo's staff admit artists, review the work artists submit, and set the fee, the artist's share and the royalty for each piece. Both the creator record and those terms are attached to the same token, so a buyer can check who Totemo attested made the work and the artist is paid whenever it sells. A manager can publish for an artist who holds no cryptocurrency, and the artist is still recorded as the creator.

The work disappeared within months and earned its makers nothing
Street art has an audience and no way to reach a buyer. Paint goes on someone else's wall. It gets covered, demolished or worn off, usually inside a year. Even where a collector wanted a piece, there was nothing to hand over, and a photograph proves nothing about who painted it.
Totemo's founder, Marty Roberts, had been photographing this work around Tokyo. He put it plainly: artists "don't get paid, and they take a lot of risks", and the work is "ephemeral, so it will be destroyed eventually".
Totemo's answer was to make something durable out of the same work: photograph the finished piece, animate it with the artist, and sell that as a digital work the artist had authorised. Walls stayed where they were and eventually went.
Street art in Tokyo had a following and new work every week, and no way to turn either into a transaction. An artist's share of a sale was the first money most of this work had ever produced, and Totemo took a fee on a category nobody else was selling.
because its margin sat in terms it set
piece by piece
The money arrived from several places, and never in the same proportions twice. The first sale. A share of resales inside Totemo. Live events, which settled outside the platform and where most buyers reached for a card. And a payment to whoever owned the wall, who had otherwise got nothing for it.
Totemo could have run this by hand: agree terms with the artist offline, mint on an existing marketplace, sell there, then pay the artist itself. That route was cheaper and it was available. It would have meant giving up most of the gallery operations and taking on the job of paying every artist out of its own account. Building the platform made the payment direct and kept the operations in one place. The company wanted "complete control over this system" and "spent a lot of time building out the tech" instead.
The case rests on three conditions, and each one set a requirement for the build.
- Artists have to accept being represented, so the platform has to let one person act for another without the work changing hands.
- Buyers have to take Totemo's word about who made a piece, so that record has to be checkable by someone outside the company.
- And no platform-wide rate can carry terms that change from piece to piece.
What Totemo brought to this that nobody could buy was the roster itself: relationships in Tokyo's street-art scene, built by introduction.
Solution
A Totemo staff member stood between the artist and the chain
Once someone at Totemo has to approve every piece, the software needs to know who they are, what they may decide, and who can act for an artist who is not there.
We had to settle which of that belonged on a blockchain. Three things had to hold whether or not Totemo was still there to vouch for them.
Work had to stay bound to whoever made it, including when somebody else published on their behalf. Roles that decide what happens to a piece had to be recorded, because they determine where the money goes later.
And the payment had to run without Totemo in the middle: one sale owed the artist, Totemo, sometimes a previous collector and sometimes somebody with no account at all. The buyer's wallet sends that transaction straight to the chain, so Totemo never receives the artist's share. Sales at live events settled outside the platform, where most buyers reached for a card.
We defined the product and wrote the requirements in 2021, then shipped version 1 in October 2022. Monthly releases continued through Q2 2023, and we supported the platform with updates as needed until early 2024.
the product before writing any of it
Requirements and architecture. This is analysis work before it is engineering work, and we started with written documents. A software requirements specification covered six user roles, sixteen process flows, the placement and transaction types, the moderation rules and the money model. A system architecture document ran alongside it.
Design, signed off before build. UX and UI began as mockups, moved to full designs, and went to Totemo for approval before anyone wrote production code.
We designed for the mobile browser first and brought desktop layouts after, because that is where the audience for this work already was.
MVP, then live operations. We built the MVP, then released into production on a monthly cadence. After launch the work became ordinary product engineering on a running system, with real works, real collectors and real money moving through it.

Frequently asked questions about NFT marketplace development
-
How long does it take, and what drives the cost?
A basic marketplace MVP is usually quoted at around three months and an enterprise-grade platform at six to nine. Totemo ran longer. Cost sits in the operating rules: who may publish, what has to be approved, and how each sale is split. Those are decisions before they are code.
-
Could this have been built without a blockchain?
Most of it, yes. Approvals, roles and split payouts are ordinary application work. What changes is who is trusted and for how long. Someone has to hold the money in transit. The creator record becomes a claim the company makes about itself. And the collector’s asset ends when the company does.
-
What do collectors keep when a platform closes?
Tokens and their history stay on Ethereum, in their owners’ wallets, and can be moved or traded elsewhere. What ends is everything the platform supplied: the interface, the studios, the catalogue and its revenue rules. Any product that issues assets should settle early what a holder still has if the company stops.
