Keel

Keel is a Solana-native on-chain capital allocator that sits between the Sky stablecoin ecosystem and Solana's DeFi and tokenized-asset markets. Launched in September 2025 at Solana APEX, Keel deploys institutional-scale liquidity across Solana protocols — lending markets, liquidity pools, routing infrastructure, and tokenized real-world assets — at a speed and scale that Solana's monolithic architecture uniquely enables.

Background: The Sky Endgame and the Stars Model

Sky, the rebranded form of MakerDAO, issued a strategic restructuring called Endgame that breaks its ecosystem into smaller, independently governed units called stars. Each star operates its own balance sheet, governance, and product focus while drawing from Sky's combined USDS and DAI stablecoin reserves, which together exceed $7 billion in supply.

Keel is the third star in this architecture. Spark, the first star, manages more than $10 billion in TVL on Ethereum. Grove, the second, focuses on collateralized loan obligations. Keel is Sky's dedicated Solana arm — the first star purpose-built for a non-Ethereum chain — and reflects Sky's conviction that the next phase of on-chain finance will be shaped by Solana's throughput and settlement speed.

How Keel Works

Keel functions as an on-chain balance sheet with direct access to Sky's USDS decentralized stablecoin reserves through the Sky Allocation System. It borrows USDS at a defined cost and deploys that capital programmatically across Solana DeFi protocols and tokenized asset markets, targeting risk-adjusted yields that exceed its borrowing cost. The spread between the two is Keel's economic engine.

This model allows Keel to scale without a fixed capital ceiling. As long as the protocol continues to generate returns above its cost of capital, it can access additional allocation from Sky's reserves. The roadmap targets up to $2.5 billion in total deployment across DeFi and real-world asset markets.

The capital allocation is dynamic and programmatic, not discretionary fund management. Keel positions itself across lending markets, routing infrastructure, and liquidity pools based on where risk-adjusted returns are available, and adjusts those positions as market conditions shift.

Key Integrations

Keel's initial integrations on Solana include three foundational protocols:

• Kamino: Keel supplies liquidity to Kamino's lending markets, deepening the pool for borrowers and generating yield on deposited USDS.
• Jupiter: Keel participates in routing infrastructure, supplying liquidity that improves swap execution across Solana.
• Raydium: Keel provides capital to Raydium's liquidity pools, supporting one of Solana's primary automated market makers.

These integrations represent the first phase of Keel's DeFi deployment. The protocol is designed to expand its integration surface as the Solana ecosystem grows and as new protocols meet Keel's risk criteria.

The Tokenization Regatta

In December 2025, Keel launched Season 1 of the Tokenization Regatta — a structured initiative to bring tokenized real-world assets onto Solana. Keel committed up to $500 million in capital allocation to selected tokenized asset issuers, a deployment projected to increase Solana's total RWA market value by more than 60 percent.

Applications opened December 11, 2025, through two tracks. The first track targets assets ready for immediate deployment within Q1 2026. The second track is a native pipeline for assets in development that may qualify for future allocation consideration.

The selection process runs as a Request for Proposal evaluated by contributors from Keel, the Sky Risk Council, Particula, and Kinetika Research. Evaluation criteria center on tokenization quality, sustainable risk-adjusted yield, and liquidity profile. More than 40 institutions expressed interest in participating in the first season. Target asset classes include tokenized bonds, commodities, and equities.

Team and Contributors

Keel is developed by Matariki Labs, with Cian Breathnach serving as CEO. Breathnach has articulated the founding thesis as a belief that the next phase of on-chain finance growth requires not just new assets but liquidity accessible at speed and scale — and that Solana is the first chain where both conditions are met simultaneously. Rune Christensen, Sky's co-founder, has backed the initiative, and Solana Foundation president Lily Liu participated in the protocol's public debut.

Solana Ecosystem Fit

Keel addresses a structural gap on Solana: the chain has deep application-layer activity in trading, lending, and liquid staking, but has lacked a dedicated institutional-scale liquidity layer that can programmatically route capital where it is most productive. By drawing on Sky's multi-billion dollar stablecoin reserves and deploying through Solana's high-throughput settlement, Keel brings a capital infrastructure layer that Ethereum-native equivalents like Spark have provided for that ecosystem.

Matariki Labs began building Keel in November 2024, roughly a year before its public launch at Solana APEX in September 2025. That timeline spans concept to live deployment with an initial DeFi integration set and a $500 million RWA initiative already underway by end of year.
