Osero Raises $13.5M to Take On Circle and Tether in the Stablecoin Yield Game

Osero Raises $13.5M to Take On Circle and Tether

For years, the stablecoin business has operated like the world’s most profitable mattress store. Customers hand over their cash. The store invests that cash in Treasuries and short-term debt, collects the yield, and hands the customer back a token worth exactly one dollar. No interest. No upside. Just a receipt. The issuers, Circle, Tether, and the rest have turned that model into a money-printing machine. DeFiLlama data puts the stablecoin market north of $300 billion. The yield on the assets backing those tokens? That flows straight to the issuers’ bottom lines. The holders get stability. They get speed. What they do not get is paid.

Osero thinks that arrangement is ripe for disruption. The stablecoin yield infrastructure project, incubated by Stablewatch and Soter Labs, announced Monday that it has raised $13.5 million in a round led by the Sky Ecosystem and co-led by Plasma. The cap table reads like a directory of crypto’s most serious builders: USDT0, Maple, Accountable, Four Pillars, RedStone, The Rollup, and Kairos Research all pitched in as angel investors.

The raise itself is not enormous by crypto standards. What matters is what Osero is building, and who it is building it with.

Sky is not some upstart protocol trying to make a name for itself. It is the entity formerly known as MakerDAO, the protocol behind DAI, now aggressively expanding the balance sheet and distribution network around USDS and sUSDS. Last year, S&P gave Sky a B- credit rating — the first time a major rating agency had ever graded a DeFi protocol. That lent Sky a credibility that most crypto projects spend years chasing and never catch. When Sky leads a round, it is not just writing a check. It is making a statement about where it thinks the industry is headed.

Plasma, the co-lead, is building a blockchain purpose-built for stablecoins. Its token sale last year raised $373 million in an oversubscribed round. That gives Plasma both the capital and the technical ambition to matter in this race. Having them alongside Sky suggests Osero is not just backed by believers; it is backed by infrastructure players who need the yield layer to exist so their own networks can thrive. Osero is attacking the problem with three products, each aimed at a different slice of the market.

Osero Earn is built for wallets, neobanks, custodians, and exchanges. The pitch is dead simple: embed the Sky Savings Rate into your own interface with roughly ten lines of code. Osero handles asset management, routing, and the underlying risk infrastructure. The front-end platform never has to build a treasury desk, hire a risk officer, or navigate the regulatory thicket that comes with managing other people’s money. They just plug in and start offering yield.

Then there is the Osero App, which gives everyday users direct access to that rate across chains. No intermediary. No platform is taking a cut. Just the user and the savings rate. The heavy artillery is Osero Foundry, aimed at asset managers and structured product issuers who want to bring yield products on-chain. Foundry will carry up to $2.5 billion in allocation capacity for anchor funding, swap liquidity, and lending liquidity. Every deployment undergoes a risk review modeled on Basel III standards, the same framework used in Sky Protocol’s own assessment process. That is not crypto jargon for “trust us, bro.” It is an attempt to bring bank-grade discipline to on-chain capital deployment.

The $13.5 million raised will fund the capital requirements for those first Foundry allocations. In other words, the money is not just for salaries and marketing. It is underwriting the first real bets. The timing is not accidental. Sky has been on a tear. In March, Sky-backed Obex announced it was spreading $1 billion across credit, energy, and AI assets to expand stablecoin yield. The protocol is building an entire ecosystem around the idea that stablecoins should do more than sit in wallets; they should work. Osero fits neatly into that thesis. But let us be clear about what Osero is really trying to do here. It is attempting to insert itself between the issuers and the holders, to capture the yield that Circle and Tether have kept for themselves and redirect it back to the people who actually own the assets. That is a dangerous idea if you are an incumbent. It is an overdue one if you are anyone else.

The incumbents are not going to roll over. Circle and Tether have regulatory relationships, banking partnerships, and years of trust that no ten-line integration can replicate overnight. They also have the benefit of scale. When you manage hundreds of billions in reserves, you can negotiate better rates, absorb compliance costs, and weather regulatory storms that would sink a smaller player. Osero’s bet is that the market is large enough and fragmented enough to accommodate a new layer. Fintech companies have known for years that their customers want yield on stablecoins. Most have lacked the infrastructure to offer it without becoming asset managers themselves. Osero is essentially saying: we will handle the messy backend, you take the user relationship, and together we will split the yield with the people who actually supplied the capital.

Whether that model scales is an open question. The stablecoin market is fiercely competitive, and the incumbents have every incentive to protect their margins. But $300 billion in idle capital is a powerful magnet. And with Sky’s balance sheet, Plasma’s blockchain, and a roster of angels who know this business inside and out, Osero is not just talking about changing the game. It is putting chips on the table. The house may not let it play. But for the first time in a while, someone is making them sweat.
