Stablecoin yield from laundromats: why 13–15% is more defensible than 4.5% from your bank

The right response to a 13–15% yield claim is skepticism. Most yield in crypto doesn't survive one question: where does the money actually come from?

Token emissions stop when protocols stop printing. Lending spreads compress when credit tightens. The yield was always a condition, not a fact. A number that exists until the thing holding it together doesn't.

A laundromat running 300 wash cycles a day doesn't have that problem.

Where the money comes from

DualMint's yield comes from machine operating revenue — laundromats, HVAC units, vertical farms. The source isn't token incentives or lending demand. The machines run the same number of cycles in a downturn as they do in a run-up, because the people using them don't have a portfolio to worry about.

US laundromats average 60% gross margins on roughly $150,000 in annual revenue. Net margins run 20–35% on deployed capital. The yield ceiling is that operating margin, not the federal funds rate. A savings account pays 4.5% because benchmark rates are sitting there today. Cut rates by 200 basis points and the savings account follows. A laundromat that earns 60 cents gross on every dollar of revenue earns 60 cents regardless of what the Fed does in September.

That's not a DeFi mechanic. It's how margin businesses have always worked.

How the numbers get checked

Every asset generates IoT telemetry: cycle counts, uptime, maintenance logs, revenue patterns. That data gets cross-referenced against operator revenue reports each month. A machine running 50 cycles cannot be reported as 1,000 — the telemetry catches it. Physical inspectors also review assets quarterly, on-site.

DualMint calls this usage-risk underwriting. The machine's data determines whether it earns yield, not a credit file. If an operator fails, the asset gets reassigned to a backup. The machine keeps running.

Twelve months of distributions

Since May 2025, the DualMint marketplace has distributed yield every month without missing one. Zero operator defaults across the full portfolio. The period covered three Fed decisions and a DeFi exploit that pulled $8 billion from the market in 48 hours. The laundromats ran the same cycles through all of it.

Twelve months without a default isn't a guarantee. It's evidence the underlying model holds when things around it are breaking.

The actual numbers

Effective yield depends on how long you lock up: 8% for flexible access, up to 13% for a 12-month term. Gross yields from the machines themselves run 15–25%; the vault keeps a liquidity buffer of 20–70% in reserve to handle redemptions, which brings effective returns below the gross figure.

The Boring Yield Index, the pooled product for institutional depositors, isn't live yet. Pre-deposit capital earns T-bill rates through M0 until the vault opens in Q3 2026. The 12-month distribution history above comes from the 1:1 NFT marketplace, which has been running since May 2025.

The yield source is the point

Every protocol has a number. What most don't have is a yield source that works regardless of what crypto does next week.

A laundromat was running wash cycles before DeFi existed. It will keep running them through whatever comes after. Whether 13% is the right number for the risk is a question each depositor has to answer for themselves. But the question of where the money comes from has an unusually specific answer for this category: quarters, going into a machine, every day.
