Stablewatch incubates Osero with a $13.5M raise to power stablecoin earn products
MAY 21, 2026 • 2 MIN READ
Osero will operate within the Sky Ecosystem, managing a portion of the Sky Protocol's balance sheet and driving adoption of sUSDS, Sky Protocol's flagship yield-bearing stablecoin.
Stablewatch, the stablecoin yield intelligence platform, announced the launch of Osero, a project it has been incubating over the past year. Osero has raised $13.5M in a funding round led by the Sky Ecosystem as part of its genesis capital allocation, co-led by Plasma and with participation from a group of angel investors representing Spark, USDT0, Maple Finance, Accountable, RedStone, RollupTV, Four Pillars and Kairos Research.
Stablecoins hit $300B+ in circulation, but the underlying yield belongs to the issuer while most holders earn zero. Moreover, every fintech with stablecoin balances has a dormant revenue feature on its balance sheet.
Osero’s stablecoin savings account is designed to let users earn in the products they already know and use, rather than having to move funds to a separate DeFi platform.
"Everyone is building a neobank right now. The differentiation used to be UX, now it's yield. The platforms that win the next five years are the ones that can offer their users a sustainable, transparent return on idle stablecoins without taking on asset management risk themselves. Osero is the infrastructure that makes that possible and Sky's balance sheet is what makes it credible.” — Piotr Saczuk, Founder of Osero
Accessible, trustworthy savings products are standard in traditional banking but still rare in crypto. Today, if a wallet, exchange, or neobank wants to offer stablecoin yield to its users, it has to become a DeFi asset manager or hire one.
"Yield is one of the harder things to get right in a consumer product. Osero have built a yield product designed to hold up as it scales. As Plasma One grows globally, solutions like Osero are how real, scalable yield reaches users on their stablecoins." — Paul Faecks Founder of Plasma
Osero is powered by the most reliable source of yield: Sky Savings Rate with $15B in total collateral and $5.6B+ in liquidity and layers of capital protecting deposits. Sky has grown to $11B in USDS supply as of May 2026, with over $200M in yield paid out (YPO) to sUSDS holders.
"I am excited to see the Sky Ecosystem continue to scale and welcome its newest agent, Osero, which will focus on giving users across a range of applications access to the Sky Savings Rate, in addition to seeking out differentiated exposures so Sky can continue to grow into new markets as the global capital allocation network." — Rune Christensen, Founder of Sky Protocol
Osero operates as a legally separate foundation, distinct from Stablewatch, with Stablewatch serving as contributor. Osero was incubated in partnership with Soter Labs, trusted governance and managed operations provider for the Sky Ecosystem.
