In diligence

IN MOTIONProperty title

Yarrow Vault

Most of Property title died in the screen. Yarrow Vault did not.

The window is a few days. After that Yarrow Vault archives. Diligence does not reopen as a live conversation.

Yarrow Vault — A permissioned record of title, invoices, warehouse receipts or port documents for houses that already finance or move goods. The event is the product. The bill of lading does not get replaced by a meme.

In a 14-day diligence sprint (day 1). This is when the story, the customers and the legal path get written down — or the file stops.

5 live counterparties in the thread. The public page is the overflow.

Diligence, not a prospectus. RCA Pad does not allocate, take orders, or close funding. If this company raises, it raises with its own counsel.

The wedge

Per title event

The wedge is the courier: two days of documentary lag is a spread.

Why the desk took it

A real job, not a ticker.

They brought a redacted bill, not a tokenised barrel.

Traction

One named pilot (redacted).

Founded 2025, headquartered in Dublin. One named pilot on file (redacted in public). 6 nodes or connected surfaces reported. Desk diligence score 89/100. Sprint day 1 of 14. A national registry counterpart, not a scrape. A dual-control drill exists on paper. We have not watched it live yet — that is the next ask.

Next 12 months

Which law governs title — written, not assumed.

Contour tried a network. This is an event on cargo that already moves. They win if they are cheaper than the internal build, not cheaper than a protocol.

The brief

How a serious reader should hold this.

The decline pile in Property title is not a rumour. It is how this board stays readable. Yarrow Vault is what survived. That is the sell.

If you leave this page without opening the claims table, you have read marketing. The scarce version of Yarrow Vault is the version that survives counsel. It is on a clock.

The auditor of a redacted pilot has seen a dual-record. Switching away now means a new auditor conversation. That is the switching cost — not the logo.

From the founder

This communication is not an offer. Participation mechanics do not exist on this pad. If a later reader treats the public stack as the offer, the stack was already wrong.

From ops

A dual-control drill exists on paper. Production evidence is the next artefact, not a tweet.

From counsel

The legal source of truth stays with the incumbent register, admin, or custodian. Yarrow Vault does not attest to its own facts.

The window

Miss this and you read the archive.

The decline pile in Property title is full of companies that looked the same on slide one. This one is listed.

Restricted markets stay dark. Named markets are live. That discipline is the scarce thing.

The scarce thing is not the company. It is the next a few days of a live conversation.

The bet

Why this company exists.

The wedge is the courier: two days of documentary lag is a spread.

Banks want to digitise without putting a commodity on a public chain. Warehouses will not be first movers. A permissioned title event they already recognise is the on-ramp.

Documentary trade is a trillion-scale flow. Software that shortens a hold by two days is a spread.

Versus the field

L2 wrappers are cheaper. They are also a different perimeter — and declined here. Yarrow Vault is priced as software against an invoice that already exists.

The live path is Not offering — locked. Proposed Regulation Crypto Assets is not treated as a calendar slot. Build as if it never opens.

How it works

01A document that already exists is hashed and evented
02Title changes when the parties that already can change it say so
03Financiers see the state they are underwriting
04No public listing of the cargo as an asset
05Title changes only when the parties that already can change it say so
06A named counterparty verifies; Yarrow Vault does not attest to its own facts.

The wedge

Why this one, not the other one.

They sell: Per title event
Who pays: A national registry counterpart, not a scrape.
Unit economics: They win if they are cheaper than the internal build, not cheaper than a protocol.
Moat on file: Dual-control on title change — the fraud case is the feature.
Switching cost: Permissioned connectivity is the moat. Public endpoints would erase it.
Vs the comps: Contour tried a network. This is an event on cargo that already moves.
Why we listed it: They brought a redacted bill, not a tokenised barrel.

Next twelve months

What has to be true.

Which law governs title — written, not assumed.

A dual-control drill exists on paper. We have not watched it live yet — that is the next ask.

Growth money would extend the record to a second geography, still permissioned.

Risks

What can kill it.

The one that actually kills it

The founder wants a public book

The moment Yarrow Vault asks this pad to allocate, sell, or complete funding, the listing ends. That is not a moral project. It is how a services firm stays a services firm.

Legal title

If the court still wants the paper, the chain is a copy. Ask which jurisdiction has said otherwise.

Warehouse adoption

One bank is not a network. The warehouse has to write the event.

Public token

Tokenising the cargo for a crowd is a different, usually worse, company.

Fraud

Digitising a fake bill faster is not progress. Dual-control is the feature.

Paper still wins in court

If the court wants the original, the chain is a copy. Ask which jurisdiction has said otherwise.

Incumbent feature

The administrator, CCP, scheme or custodian can ship this as a checkbox. Yarrow Vault has to be cheaper or faster before that happens.

Ask these next

01Who is the first named paying customer — not a letter of intent?
02What happens if a founder later wants a public token?
03What does renewal look like if no round ever happens?
04Which geography is actually locked, and which is a hope?
05Has counsel written the perimeter in a memo you can file?
06Which incumbent can copy this in a quarter, and what would they have to migrate?

Structure

Where they can operate

Named vs off-limits.

Who can decide

The technical founder is on the record as engineering. Contractors in undisclosed jurisdictions are written down as a fact, not hidden. Facts can be managed. Hiding them is how companies die in diligence.

If the first customer renews, the adapter work pays for itself. If they do not, Yarrow Vault is a services firm with a slide. The twelve-month test is renewal, not waitlist.
