Solstice has launched a tranched DeFi product on Strategy's Bitcoin-linked STRC preferred stock, splitting exposure into a senior token and a junior token. Senior holders target roughly 7% APY and stay protected unless STRC falls below $47.66 — about 52% under its $100 par value. The model depends on Strategy continuing to defend STRC's price and on holders not rushing for the exits together.
Solstice has repackaged the risk in Strategy's STRC preferred stock into a two-tier product that only breaks for senior holders if STRC drops below $47.66. STRC currently trades near $95.315, putting that threshold at roughly half of today's price and about 52% below the security's $100 par value.
Strategy's six-week defense of STRC
Strategy has spent the past six weeks actively managing STRC's price toward its own $99 to $100 target, combining a dollar reserve policy, a revised dividend structure, and buyback authorizations. Between July 20 and July 26, the company repurchased 288,930 STRC shares for about $25 million at an average price near $86.52.
In early August, Strategy sold $108.6 million worth of Bitcoin and used the proceeds to repurchase 1,152,020 STRC shares, on top of a $4.65 billion dollar reserve reported as of Aug. 9. Bitcoin itself is up 0.26% over the past 24 hours, holding a $1.28 trillion market cap.
Solstice built its risk model on that defense continuing, and lists any shift away from Strategy's policy among the product's named risks.
Splitting STRC into senior and junior tokens
The structure splits exposure into two tokens, senior SR-strcUSX and junior JR-strcUSX, with $50 of combined $100 exposure going to each — a 50/50 split that produces a 200% senior coverage ratio. Junior absorbs realized losses first in exchange for a higher residual yield, while senior targets about 7% APY.
STRC's stated 12% annual dividend implies close to a 12.59% Bitcoin-fueled yield at its current price, before Solstice's tranching and fees split that spread between the two sides.
What could still break the model
Once STRC trades below a specified threshold, the protocol enters a restricted mode that halts junior redemptions and new senior minting at the same time, aiming to stop the coverage ratio from deteriorating further.
Solstice modeled the previous drop into the mid-$70s: STRC bottomed near $73.62, about 35% above the $47.66 threshold, and senior stayed unimpaired regardless of what junior holders did. But if every senior holder had redeemed during that window, junior would have taken a roughly 50% drawdown.
Junior's fate turns on whether senior holders stay put or rush for the exits together — the redemption pattern Solstice's own retrospective model flagged as the real risk.
