Stablewatch Incubates Osero with a $13.5M raise

A year ago, a question kept coming up in our work as a yield intelligence platform: stablecoin yield exists and works, so why are intuitive savings account options so limited within existing stablecoin platforms? Something so obvious in traditional banking, yet so rare onchain. Neobanks started to pop up to address the gap between fintech experience and the crypto audience. Yet still, the majority of them lack access to the premier onchain risk-adjusted yield.

The data is clear. There are $300B+ in stablecoins however the underlying yield belongs to the issuer while holders earn nothing. Every fintech and neobank with stablecoin balances is sitting on a dormant revenue feature, because taking on asset management complexity isn't their business. DeFi apps post APY numbers with no context for what backs them. And users who want to put their stables to work are forced to navigate fragmented apps, opaque mechanics, and risk they can't properly assess.

To address this issue, Stablewatch has been incubating a project with Soter Labs, trusted governance and operations provider for the Sky Ecosystem, and today we're launching Osero. Osero has raised $13.5M in a funding round led by the Sky Ecosystem, co-led by Plasma and with participation from a group of angel investors representing USDT0, Maple, Accountable, Four Pillars, RedStone, The Rollup, and Kairos Research among others.

What Is Osero

Osero is stablecoin yield infrastructure. It exists to solve distinct but related problems in the market, through three products.

Osero Earn is for platforms (like wallets, neobanks, custodians, and exchanges) that want to offer their users the premier risk-adjusted savings rate without taking on asset management risk themselves. The integration is seamless: ten lines of code to embed the Sky Savings Rate directly into a product's existing interface. Osero handles everything underneath so partners can focus on their product. The goal is to enable users to earn in the products they already know and love.

Osero App gives retail and institutional users direct access to the Sky Savings Rate through a simple, clean interface. Deposit any stablecoin on any chain, earn the savings rate, redeem at any time. What sets the App apart is the transparency and the experience. Users get a live view into the balance sheet backing their deposit, liquidity available to meet withdrawals and layers of capital protecting deposits. The Osero App is designed to feel like a fintech product, not a DeFi app.

Osero Foundry, is a full-stack origination platform for asset managers, fund issuers, and structured product providers looking to bring their products onchain. Foundry handles the complete stack with up to $2.5B in allocation capacity for anchor funding, swap and lending liquidity. Every deployment goes through a rigorous Basel III inspired risk assessment process.

Taken together, Osero's three products form a single access layer so that idle stablecoins can be put to work and earn the best risk-adjusted return available.

Why We Built This

Stablewatch is a data and risk intelligence platform where we index yield products onchain and provide risk advisory services as a core contributor to the Sky Ecosystem. That work gave us an unusually complete picture of the market, and a close-up view of the balance sheet that sits at the center of it.

Sky has grown to over $15B in total assets under management as of May 2026, with over $200M in yield paid out to sUSDS holders. The Sky Savings Rate is the leading yield solution in DeFi generated by a diversified balance sheet, transparent, and battle-tested at scale. It is, by any measure, the most credible yield source onchain.

Stablewatch's risk framework was already the methodology we would use to underpin Osero's due diligence process. The logical step was to build the distribution and origination layer on top of that knowledge.

That's what Osero is: the stablecoin yield layer that connects anyone, anywhere, regardless of which platform they use or which chain their funds sit on, putting idle stablecoins to work.

The Raise

The $13.5M raise funds capital requirements, specifically, the risk capital needed to underwrite Osero's first cohort of Foundry allocations, structured in line with the Basel III-inspired framework that governs the Sky Protocol’s risk assessment process. Capital requirements are determined during the risk review for each deployment, and the raise is sized to meet them for the first wave.

The Sky Ecosystem led the round as part of its genesis capital allocation to Osero as an Agent within the Sky Ecosystem. It means Osero enters the market as a crucial participant with a dual mandate: distributing USDS and sUSDS to institutional and retail end users, and allocating to institutional-grade assets to diversify the largest onchain balance sheet.

Osero operates as a legally separate foundation, distinct from Stablewatch. Stablewatch serves as a core contributor, providing the risk methodology, technical know-how and the ecosystem relationships that Osero is built on.

After months of building, we couldn't be more excited to invite you into this next chapter with us.
