Key Takeaways
- • Osero, a stablecoin yield infrastructure startup incubated by Stablewatch and Soter Labs, secured $13.5 million in funding led by Sky Ecosystem and co-led by Plasma, with participation from angel investors including USDT0, Maple, Accountable, Four Pillars, RedStone, The Rollup, and Kairos Research.
- • Osero is launching concurrent access to a $2.5 billion USDS credit facility extended by Sky Ecosystem, with capital allocation designated for anchor funding, swap liquidity, and lending liquidity across initial Foundry deployments.
- • The platform addresses a structural inefficiency in the $300+ billion stablecoin market: yield from assets backing stablecoins currently accrues to issuers like Circle and Tether rather than token holders, limiting savings product offerings for fintech firms and custodians.
- • Osero is deploying three products—Earn (embeddable in ~10 lines of code), App (direct user access across chains), and Foundry (structured product issuance for asset managers)—each routing deposits into the Sky Savings Rate while Osero manages asset routing and risk infrastructure.
- • Foundry deployments will undergo Basel III-inspired risk reviews, with capital from the $13.5 million raise earmarked to underwrite the first cohort of deployments using the Sky Protocol's assessment framework.
Summary
Osero, a stablecoin yield infrastructure project, has closed a $13.5 million Series A funding round led by Sky Ecosystem (formerly MakerDAO) and co-led by Plasma. The round included participation from a consortium of angel investors representing USDT0, Maple, Accountable, Four Pillars, RedStone, The Rollup, and Kairos Research. Simultaneously, the company announced access to a $2.5 billion USDS credit facility extended by Sky Ecosystem, positioning Osero as a significant participant in the emerging stablecoin yield infrastructure market.
The funding directly addresses a market inefficiency in the rapidly expanding stablecoin sector. According to DeFiLlama data, stablecoins have surpassed $300 billion in aggregate value. However, the yield generated from assets backing these stablecoins currently accrues primarily to issuers such as Circle and Tether, leaving token holders without direct returns. This structural limitation has constrained fintech firms, custodians, and exchanges from offering competitive stablecoin savings products without managing underlying assets themselves—a friction point Osero is designed to eliminate.
Osero is launching three integrated products. Osero Earn enables wallets, neobanks, custodians, and exchanges to embed the Sky Savings Rate directly into their interfaces with minimal integration overhead (approximately 10 lines of code). The product routes deposits into the Sky Savings Rate while Osero handles underlying asset management, routing, and risk infrastructure. Osero App provides retail users with direct access to the rate across multiple blockchain networks. Osero Foundry allows asset managers and structured product issuers to bring yield-bearing products onchain, supported by up to $2.5 billion in allocation capacity for anchor funding, swap liquidity, and lending liquidity.
The $13.5 million capital raise will fund operational and capital requirements for Osero's initial Foundry deployments. These funds will underwrite the first cohort of product launches, with each deployment subject to a Basel III-inspired risk review process aligned with the Sky Protocol's assessment methodology. This institutional-grade risk framework reflects the protocol's focus on capital efficiency and regulatory alignment as the stablecoin yield space matures.
