Sky Ecosystem: May Financial & Operational Update

Welcome to the Monthly Financial & Operational Update, published by the Sky Frontier Foundation.

Each month, this briefing covers the protocol data, capital markets activity, and governance developments that matter to ecosystem participants.

Executive Summary

May 2026 marked another step forward for Sky Ecosystem, which expanded the Sky Frontier team, the Sky Agent Network, and public financial reporting for Sky Protocol. Sky Frontier Foundation also published its inaugural Transparency Report, disclosing the Foundation's own financial activity from inception through Q1 2026.

At the protocol level, supply, collateral, and revenue all grew year-over-year, while monthly Net Protocol Surplus held flat as the protocol's yield-bearing obligations scaled alongside revenue. Sky Reserves closed the month at $72.27M, and cumulative 2026 Net Protocol Surplus through May crossed $66M, already past the full-year 2025 figure. May was also marked by one of the larger security incidents in DeFi this cycle, and Sky Protocol operated through it without protocol-level impact. The roughly $230 million LayerZero-bridge exploit drove a multi-billion-dollar contraction in Aave TVL and triggered emergency market freezes across its deployments, while Sky Protocol carried no exposure and operated normally throughout, a live test of the risk framework's third-party exposure controls.

Key Highlights:

• First Quarterly Insights Call was held on May 13. Rune Christensen and Framework Ventures Co-Founder Vance Spencer walked through Q1 2026 results and the 2026 outlook. The Insights Call is intended to run quarterly alongside the Quarterly Report.
• Greg Feibus joined Sky Frontier Foundation as Global Head of Capital Markets. Feibus brings 15 years of capital markets experience from Midas, Ondo Finance, Anchorage Digital, and FIS Global.
• Sky Frontier Foundation released its Transparency Report on May 26. The document details top-level financials, grant fund deployment, treasury operations, and strategic positions. The full report can be found here.
• Sky Agent Network expanded with Osero, an integration framework targeting Neobanks and Fintech . Osero is shipping its core product: Earn, which launched in late May, allowing platforms like wallets, neobanks, custodians, and exchanges to offer the Sky Savings Rate to their users without directly managing stablecoin strategies or underlying assets.
• Sky Protocol Financial Dashboard launched. The dashboard went live at financial.skyeco.com on May 6. Readers can see the protocol's balance sheet, P&L, collateral breakdowns, Sky Agent allocations, loss waterfall, and risk capital metrics in real time.

Sky Protocol Financials & Onchain Metrics

The protocol's asset growth outpaced its circulating stablecoin base in May: Protocol Collateral grew 54% year-over-year against 48% for Total Stablecoin Supply. The result is a wider collateral buffer per dollar of USDS in circulation, which strengthens the protocol's overcollateralization position and gives more headroom against collateral price moves or borrower-side stress.

Expenses grew slower than the top line: Net Protocol Revenue grew 32% YoY against 14% for Gross Protocol Revenue, meaning expenses didn't scale proportionally with revenue and the protocol retained a larger share of each gross dollar in net.

Capital Markets Activity

Sky Protocol's strongest quarter on record. On the Insights Call, Rune Christensen discussed the protocol’s financial performance in the first quarter, anchored by a $46.04M Net Protocol Surplus that exceeded the Foundation's base projection by 80% and nearly matched the full-year 2025 figure in a single quarter. He also detailed the capital restructuring decisions enacted via the March 2026 governance vote and the protocol's three growth engines for the rest of the year: Sky Agent Network expansion, USDS distribution, and the Sky Reserves buildout. Vance Spencer pointed to Cohort 1's lift of Sky Agent Vaults from $615M to $6.99B over twelve months. Full recording here.

Sky Ecosystem led a $13.5M funding round for Osero on May 12. Osero is building the productized distribution layer that closes the gap between stablecoin issuers, who capture most of the yield today, and the fintech platforms and end users that hold the supply but earn no native yield from it. The round is structurally distinctive: $10 million of the proceeds is allocated to reserve requirements that protect both Osero users and Sky Protocol from potential losses, with the remainder funding capital requirements for Osero's first Foundry allocations. That reserve mechanism aligns Osero's economics with Sky Protocol from day one.

Greg Feibus's mandate at Sky Frontier Foundation. Effective May 18, 2026, Feibus became the first dedicated capital markets executive for the Foundation. His focus will be on institutional allocators and structured-product partners, with the role engineered to deepen flows between traditional financial markets and the onchain ecosystem.

Governance & Risk Management

Sky Savings Rate adjusted to 3.60% on May 26, as Sky Governance strengthened the surplus buffer. The adjustment sits within Sky Protocol's broader capital protection framework, which has set a Solvency Reserve target of $150 million and prioritizes earnings allocation toward building reserves rather than distributing them. Sky Reserves stood at $72.27M at month-end, up from $50.90M at the end of Q1, putting the protocol roughly halfway to the Solvency Reserve target.

Operational Updates & Integrations

Sky Savings Rate distribution via Binance Wallet. Direct access to the SSR via sUSDS is now live through the DeFi section of Binance Wallet, with sUSDS share value updating in-app as users hold the world’s largest yield-generating stablecoin. Additionally, Spark, a Sky Agent operating in DeFi lending, launched a 30-day campaign with Binance Wallet on May 28, featuring two boosted Savings Vaults backed by $350,000 in user incentives.

Looking Ahead

The Sky.money app launched Fixed Yield on sUSDS via Pendle Finance. Announced on June 2 and accessible on the Sky.money interface, the integration adds a fixed-yield option for sUSDS holders alongside the existing Sky Savings Rate. Pendle's framework splits sUSDS into a Principal Token (PT) that redeems at a market-determined fixed rate at maturity, and a Yield Token (YT) that captures the variable SSR residual until then. The PT structure is close to a TradFi zero-coupon bond, which makes sUSDS plug-and-play for institutional allocators evaluating it alongside money market funds and short-dated fixed-income instruments. It is the first time the Sky yield primitive offers a real choice between variable and fixed exposure, broadening who can hold sUSDS at scale.

Sky Ecosystem heads into the second half of 2026 from its strongest institutional position to date. In the next update we will preview the second quarter results due to be published in July, discuss the early adoption of Fixed Yield on sUSDS via Pendle, and cover further Sky Agent Network activity through June.
