Stablecoin infrastructure startup Osero has raised $13.5 million in a funding round led by Sky Ecosystem and Plasma, according to details shared by the company and participants involved in the deal.
The fundraising was completed through a simple agreement for future tokens (SAFT), though the company undisclose its valuation. Other investors included individuals and firms connected to Maple Finance, RedStone, Kairos Research and The Rollup.
Osero was incubated by Stablewatch, a contributor to the Sky Ecosystem. The company is developing software intended to help wallets, exchanges and fintech platforms integrate stablecoin yield products tied to Sky’s USDS and sUSDS tokens.
The funding arrives during a period of rapid expansion in the stablecoin sector, where companies are increasingly competing over how yield generated from reserve assets is distributed across users, protocols and intermediaries.

Reserve Allocation Signals Focus on Risk Controls
According to the company, $10 million of the $13.5 million raised has been allocated toward reserve requirements intended to absorb potential losses tied to future deployments and integrations.
That allocation is notable at a time when crypto yield products continue facing scrutiny following the collapses of several centralized lenders and high-yield platforms during the 2022 market downturn. Since then, investors and institutional partners have increasingly focused on liquidity management, collateral quality and reserve structures rather than headline yield figures alone.
Osero said future deployments connected to the Sky Protocol would undergo internal risk assessment processes. The startup currently operates with a 13-person team and plans to expand hiring in credit strategy and business development, according to founder Piotr Saczuk.
Stablecoin Infrastructure Becomes a Growing Competitive Market
Stablecoins were initially designed primarily as settlement tools for crypto trading, but the sector has expanded into payments, remittances and savings products over the past several years. Industrywide circulation of dollar-pegged stablecoins has surpassed $300 billion, with growth driven largely by institutional trading activity and cross-border transactions. At the same time, competition has intensified around products that allow users to earn yield on idle stablecoin balances. Saturn Credit expands STRC-based stablecoin products as firms across the digital asset sector continue developing new models for yield generation and reserve-backed financial infrastructure.
Traditional stablecoin issuers generally retain income generated from reserve assets such as Treasury bills and money market instruments. In response, decentralized finance protocols and newer crypto infrastructure firms have increasingly introduced systems that pass portions of that yield back to users through tokenized savings products or lending strategies.
That shift has created a growing market for middleware providers that can connect decentralized finance protocols with consumer-facing financial applications. Rather than building direct-to-consumer crypto products, many infrastructure firms are now targeting exchanges, wallets and fintech applications seeking embedded yield features without operating internal digital asset treasury teams. At the same time, other startups are expanding into stablecoin card infrastructure and payment-focused services as demand grows for real-world spending applications tied to digital dollar assets.
Sky Ecosystem Expands Distribution Strategy
Sky Ecosystem, formerly known as MakerDAO, has been restructuring its ecosystem following a broader rebranding initiative launched last year. Part of that strategy involves expanding the distribution of USDS and sUSDS through external partners and integrated financial applications. Osero’s business model aligns with that broader push toward distribution-focused partnerships.
The company said it is developing three products: a direct savings application for retail and institutional users, an infrastructure product for third-party integrations, and a platform focused on tokenized financial products for asset managers and issuers.
