Career

Saczuk began his career at BNY Mellon, where he served as a Trustee and Depositary Representative from April to November 2021 in Wrocław, Poland. He then joined Finoa as an Analyst from December 2021 to May 2022 in Berlin, working in the digital-asset financial services sector. From June 2022 to August 2023, he was an Associate at soonami.io GmbH in Berlin, where his work focused on blockchain and venture-related activities.

Interviews

Osero Funding

In a May 2026 interview on Stabledash, Saczuk discussed Stablewatch’s evolution from a research and data platform into a risk advisory business and its subsequent involvement in the Sky Ecosystem. He described the development of risk models such as Stable Sim and Stablewatch’s contribution to Sky's risk framework, which incorporates principles drawn from Basel III. Saczuk also discussed Osero, which Stablewatch incubated as a Sky ecosystem project, and its role in managing and diversifying a large on-chain balance sheet across stablecoins, real-world assets, private credit, and other sources of exposure. Saczuk explained that Osero operates through both a retail application offering stablecoin savings products and embedded infrastructure that allows other platforms to integrate yield products. He said Osero’s strategy includes seeking additional, less-correlated assets to reduce concentration risk, while Stablewatch plans to expand its coverage of yield-bearing assets and produce research on their underlying risks and sources of return. The discussion also emphasized transparency in assessing DeFi products and the broader transition of traditional financial assets and services onto blockchain infrastructure. ^[4]

Presentations

sUSDS

In a June 2026 episode of Where Yield Comes From – Season 1, Saczuk explained how sUSDS generates yield through the Sky Protocol ecosystem. He described the process by which USDC and USDS enter the Peg Stability Module and are converted into sUSDS, after which capital is allocated across assets including U.S. Treasury bills, BTC and ETH exposure, OTC lending, and AAA-rated corporate debt. Saczuk also outlined the protocol’s risk structure, which distributes potential losses across junior capital provided by ecosystem Agents, a stability buffer, and senior capital from Sky before losses could reach USDS holders. Saczuk also discussed the liquidity, security, and transparency supporting the system, noting the availability of billions of dollars in immediately accessible or rapidly liquidatable assets. He described Sky’s development from early e-dollar concepts through its decentralized infrastructure and the transition from MakerDAO to the Sky brand, while highlighting the protocol’s audit history and publicly available data. The presentation characterized the underlying assets as relatively short-duration and liquid, with extensive information available for evaluating the sources of yield and associated risks. ^[7]

Yield Tokens

At the Stable Summit in March 2026, Saczuk discussed the development of yield-bearing stablecoins and the rapid expansion of the market, including the shift from traditional stablecoins toward products incorporating tokenized strategies. He described Stablewatch’s role in providing research and risk-management models, including FRTB and Monte Carlo analysis, and examined how regulatory changes and increasing competition affected major stablecoin yield strategies. Saczuk highlighted Sky Protocol’s diversified approach, while noting that once-popular delta-neutral strategies had become less differentiated as more market participants adopted similar models. Saczuk also focused on risks exposed by failures and market disruptions, including smart-contract issues, asset concentration, security breaches, insufficient monitoring of off-chain assets, and vulnerabilities in crypto lending markets. He cited a $2.5 billion outflow from yield products during one week in November as an example of the scale of market stress and argued that greater transparency, research, and ongoing risk monitoring were needed across the sector. He concluded by discussing Stablewatch’s partnership with Sky as an ecosystem agent and the role of improved risk-management infrastructure in supporting the continued development of stablecoin yield markets. ^[6]
