Ask most fintech founders how they would enter a market with an entrenched 3% take rate, and the answer involves a balance sheet. Undercut the incumbents, absorb the losses, buy the volume, and hope the unit economics arrive before the runway ends.
The founder behind Wagyu.xyz, who trades publicly as PerpetualCow, took a route that required almost no balance sheet at all. Seven months after launch, the platform reports having handled north of $700 million in cumulative transaction volume, on infrastructure that holds essentially no inventory and carries no spread risk. It is a useful case study in what composable market infrastructure does to the cost of starting a financial services business.
A market where the customer could not see the price
The category in question is privacy-asset conversion, and it had an unusual property: buyers had no reliable way to know what they were paying.
Conversion services in this space run what is effectively a dealer book. They warehouse assets, publish one blended number to the customer, and pocket the difference between that number and wholesale. Nothing in the transaction is itemised. There is no visible venue to compare against, so a customer cannot separate the fee from the rate. Assessments of the sector have repeatedly landed on real costs of three to four percent, against headline rates advertised at a fraction of that.
Two things kept those margins intact. The first was the absence of a reference price. The second, less obvious, was the steady disappearance of alternatives.
Regulated venues have been retreating from Monero for several years now, whether by removing the pairs outright or by walling off specific jurisdictions in response to supervisory pressure. One of the longest-running peer-to-peer marketplaces in the ecosystem wound up operations entirely after seven years of trading. Yet chain data through the same period shows usage holding firm. The buyers did not leave. Their options did.
For anyone who has watched a regulated market consolidate, the outcome is familiar. Competitive pressure is what obliges a venue to behave. Remove enough competitors and the survivors inherit pricing power they never had to earn.
Renting liquidity instead of buying it
The conventional response would have been to become a better dealer. More capital, tighter quotes, deeper inventory. That is a slow, expensive business and a poor fit for a single operator.
Wagyu.xyz sidestepped the dealer model completely. Orders are handed to Hyperliquid’s onchain orderbook, where established market-making firms bid for the fill. The platform never takes the other side of a customer’s trade. It never funds an inventory position. What the customer receives is whatever the book produces, and the operator’s revenue is a routing spread rather than a markup engineered from the customer’s ignorance of wholesale.
“There was no clever pricing model to build,” PerpetualCow said. “The wholesale price already existed on a public venue. The only reason anybody was paying four percent was that nobody had bothered to connect retail demand to it.”
Monero settles natively to the customer’s own wallet, with a wrapped instrument called XMR1 used only while the transaction is in flight. Fulfilment clocks in at a median of roughly five and a half minutes, with nine in ten orders completing inside fourteen.
The early traction was steep. Within a fortnight of going live, the service had processed around $10 million in customer withdrawals and booked approximately $200,000 in revenue, while pushing better than $20 million of incremental order flow into Hyperliquid.
That last detail deserves attention from anyone studying application-layer economics on trading venues. Wagyu.xyz is not merely a tenant of Hyperliquid’s liquidity. It is a supplier of order flow to it. The relationship compounds rather than extracts, which is a rarer position than it sounds for a product built on somebody else’s rails.
Moving the compliance check to the front of the queue
The second design decision addresses the complaint that has dogged this sector hardest.
Conversion services advertise that no identity documents are required. That holds until an order trips a screening rule, which industry estimates suggest happens on somewhere between two and five percent of transactions. At that point the customer, who was promised no paperwork, is asked for a passport and a source-of-wealth narrative in order to retrieve money already handed over. No completion deadline is owed to them, and often no legal entity exists to complain to.
PerpetualCow’s framing is that the industry misdiagnosed the problem as a policy question when it is really a question of ordering.
“Whoever is holding the funds sets the pace,” he said. “If the check runs after the deposit lands, you have built a machine where stalling is free for the operator and expensive for the customer. No amount of goodwill fixes that, because the incentive is structural. You have to make sure the situation cannot arise.”
On Wagyu.xyz the screening runs against the incoming deposit before anything is executed. Anything that fails is sent straight back to the address it came from. Because the decision happens at the perimeter, the operator is never left sitting on disputed funds with no commercial reason to hurry. The published policy commits to never requesting identity documents, and limits asset restrictions to instances of a valid order from a court of competent jurisdiction.
Publishing the thing competitors would have paid for
The strategic decision most likely to raise eyebrows in a fintech boardroom is the third one.
Every capability that made this business hard to stand up has been released as a public API. Discovery, quoting, order creation, lifecycle tracking over REST and WebSocket. A developer can point their own front end at it, apply whatever margin they like on top of the wholesale rate, and be running a conversion service without funding inventory, staffing a treasury desk, procuring screening tools or operating bridge infrastructure.
The entry cost for a competitor, in other words, has been reduced to the price of a domain and an afternoon. The company’s own onboarding advice at launch was to feed the documentation into an AI coding assistant and iterate from there, which is a fair description of the effort involved when the interface is a documented REST contract. Wallet vendors and regional operators have already shipped on it.
“Owning the pipe beats owning the shopfront,” PerpetualCow said. “Somebody will always build a nicer interface than mine. If they do it on my rails, I still clear the trade. And a market where the plumbing is public and the price is a live orderbook is a market where the four percent era is finished, which was the objective.”
Whether the wholesale bet outlasts the retail one is the open question, and it will be settled by operational record rather than architecture. But the broader pattern is legible enough for any fintech operator to borrow. Where an incumbent margin rests on the customer’s inability to check the price, the product is simply showing them the price. Making the infrastructure public is how you stop anybody, yourself included, from quietly closing the window again. Live rates are published on the platform.
About the company
Wagyu.xyz is a cross-chain conversion and bridge platform offering access to native Monero without identity verification. Founded in December 2025 and launched in January 2026 by PerpetualCow, the business routes customer orders to Hyperliquid’s onchain orderbook and screens deposits ahead of execution, returning anything that does not clear to its source address. Its public API supports independent operators building conversion services on the same infrastructure. Cumulative volume has exceeded $700 million since launch. The company is based in Reykjavik, Iceland, and can be reached at contact@wagyu.xyz.
