What is the Boring Yield Index?
Most yield products are one trade away from zero. Token emissions stop when protocols stop printing. Lending spreads collapse in a credit crunch. Even treasury-backed products move with whatever the Fed decides to do. The Boring Yield Index is built on a different premise: that the most resilient yield comes from machines that earn whether markets are up or down.
The Boring Yield Index (BYI) is a single onchain position that pools operating cash flow from three categories of physical revenue-generating assets: Ecowash coin-operated laundromats, AirUp commercial HVAC units, and RoboFarm robotic vertical farms. Cash flow from each category distributes monthly to depositors in USDC or USDT. The vault is built on the ERC-7540 async redemption standard and launches Q3 2026.
Why one position across three asset types
Each category earns differently. Ecowash revenue comes from wash cycles: non-discretionary household spending that holds flat in recessions because people don't stop doing laundry. AirUp earns through service contracts and documented energy savings, revenue attached to commercial building operations rather than consumer sentiment. RoboFarm produces agricultural output tracked by IoT harvest data, tied to food supply rather than financial markets.
Pooling them into one position isn't just a convenience. It's diversification across failure modes. A bad quarter for one category doesn't pull the others. The correlation between a laundromat's cycle count and an HVAC unit's service contract revenue is effectively zero. That's the structure behind a single yield number.
What 'boring' actually means as a risk category
The name isn't ironic. Boring is a precise description of what makes these assets work as yield infrastructure. They serve non-discretionary demand. Nobody stops washing clothes because ETH dropped 40%. Commercial buildings don't let HVAC contracts lapse because a token lost its peg. The demand is structural. It existed before this protocol and will exist after it.
That stability shows in the data. DualMint has operated the underlying marketplace since May 2025. Twelve consecutive monthly distributions. Zero operator defaults. The assets scored by the Asset Performance Index have produced continuous cash flow through a volatile market period that the machines never noticed.
How the yield is verified
IoT sensors record machine performance directly: cycle counts, uptime, service events. That telemetry is cross-referenced against operator bank deposits every month. Where they diverge, the discrepancy gets investigated before any distribution moves. A quarterly independent audit covers every asset category. Every distribution is recorded onchain.
The yield ceiling is the operating margin of the underlying business, not a rate set by a protocol. A laundromat with 97% uptime and strong cycle counts earns a specific number. That number is what distributes, minus DualMint's 10% processing fee. The 13-15% net annual target isn't a guess at what markets will pay. It's the conservative floor from businesses that have been generating that margin for years.
What goes into the vault
Not every asset from the marketplace is eligible. Vault inclusion requires a demonstrated scoring history in the Asset Performance Index at or above threshold. Assets prove themselves in the marketplace first. Only machines with a verified track record of consistent, audited cash flow graduate to the vault. That filtering is why the vault can make a yield claim without a track record of its own: the assets inside it already have one.
Withdrawals and liquidity
The vault keeps 20-70% of total value liquid in its early stages to handle redemptions without forcing asset sales. Withdrawals settle within 30 days. That window reflects how long it takes to move capital out of something physical, not a platform limitation. The async vault standard (ERC-7540) handles the redemption queue. The 30-day notice period is the honest answer to a question most yield products avoid: what does it actually take to exit?
The structure behind it
The BYI operates through a BVI Special Purpose Company, a bankruptcy-remote legal structure that holds the underlying assets separately from DualMint's operating entity. Depositors are exposed to asset performance, not to DualMint's balance sheet. The protocol is a Chainlink BUILD program member. M0 stablecoin infrastructure handles settlement. Smart contract audits are scheduled before vault launch.
The vault isn't live yet. Everything that feeds it is. The marketplace, the scoring system, the operator network, the twelve months of verified distributions: all running, all documented, all onchain. Q3 2026 is when it opens. The preparation started in May 2025.
