Osero, a stablecoin yield infrastructure project incubated by Stablewatch and Soter Labs, has raised $13.5 million in a funding round led by the Sky Ecosystem and co-led by Plasma, according to an announcement. The capital will primarily fund capital requirements for Osero's first Foundry allocations, underwriting the initial cohort of deployments under a risk framework adapted from the Sky Protocol's assessment process.

Market Context

The stablecoin market has expanded to more than $300 billion in total value, according to DeFiLlama data. Despite this growth, most yield generated by assets backing those stablecoins continues flowing to issuers like Circle and Tether, leaving holders without direct returns. This dynamic has created friction for fintech firms seeking to offer stablecoin savings products, as they would need to manage underlying assets themselves—a significant regulatory and operational hurdle.

Analysis

Osero's approach targets this gap by providing infrastructure that allows partners to embed yield products without handling asset management directly. The project is launching three distinct offerings: Osero Earn enables wallets, neobanks, custodians and exchanges to integrate the Sky Savings Rate into their interfaces with approximately 10 lines of code. Osero App provides users direct access to the rate across multiple chains. Meanwhile, Osero Foundry gives asset managers and structured product issuers a pathway to bring yield products on-chain.

The $2.5 billion in allocation capacity that Foundry will provide covers anchor funding, swap liquidity and lending liquidity. Each deployment undergoes a Basel III-inspired risk review process, a framework that could appeal to more traditional financial institutions seeking controlled exposure to DeFi yield.

Sky Ecosystem, formerly known as MakerDAO, has been aggressively expanding its balance sheet and distribution network around USDS and sUSDS. The protocol received a B- credit rating from S&P Global Ratings last year—the first such rating assigned by the agency to a decentralized finance protocol—signaling growing institutional acceptance of major DeFi players.

Plasma, which co-led the round, is simultaneously building its own stablecoin-focused blockchain. The company drew $373 million in an oversubscribed token sale last year, demonstrating significant market appetite for dedicated stablecoin infrastructure projects.

Key Numbers

- $13.5M raised in funding round

- Over $300B total stablecoin market size (DeFiLlama)

- $2.5B allocation capacity available through Osero Foundry

$373M Plasma token sale drew last year

- B- credit rating assigned to Sky by S&P Global Ratings

What to Watch

Traders should monitor whether Osero's integration partnerships materialize as announced, particularly with major wallet providers or neobanks. The Basel III-inspired risk framework could set a precedent for institutional DeFi engagement if deployments prove successful. Sky Ecosystem's continued expansion of USDS and sUSDS distribution will likely drive demand for yield infrastructure products like those Osero is building. Plasma's stablecoin-focused blockchain development remains another parallel storyline worth tracking as the sector matures.
