The Problem
Bitcoin holders face a fundamental inefficiency: the world’s largest crypto asset generates no native yield.| Problem | Explanation | Market Size |
|---|---|---|
| Limited institutional BTC yield on-chain | BTC wrappers (WBTC, cbBTC, BBTC, tBTC) earn only 1-2% in lending markets | 27-28B USD in BTC wrappers |
| Borrowing stablecoins against BTC is capital-inefficient | BTC-backed borrowers pay 5-12% interest while collateral earns nothing | 40B USD market |
| Suppressed BTC lending yields | BTC wrappers primarily serve as static collateral with minimal utilization | Under 1% typical lending APY |
The Solution
Economic exposure is through iBTCY issued by SD Global Capital Limited; BTCY is the ERC-4626 vault that makes iBTCY usable in DeFi while tracking the same NAV. BTCY targets on-chain access to the Starboard Sygnum BTC Alpha Fund (SSBAF), a market-neutral arbitrage strategy managed by Starmark Investment Management Limited (FCA-regulated). SSBAF targets 8-10% net returns at the fund level. After the 32% instant liquidity buffer and a 50 bps platform fee, holders target approximately 4-6% net annual yield, denominated in BTC. SSBAF launched in October 2025; the underlying strategy has been operated by Starboard Digital since March 2021. Target returns are not guaranteed.BTCY is a yield-bearing asset, not a stablecoin. Its value fluctuates based on NAV performance and is denominated in BTC.
