Saylor's Bitcoin stack adds USDT payment layer to 840,447 BTC reserve

Strategy chairman Michael Saylor has unveiled a Digital Finance Stack assigning Tether's USDT stablecoin the role of primary transactional gateway, with Bitcoin as the heavy capital layer while the company holds 840,447 BTC.

Saylor framed the shift as a credit exercise rather than a retreat from Bitcoin. "Strategy increased its USD Reserve by $650M and repurchased $109M of $STRC," he wrote. "This increased USD Duration by 143 days to 2.7 yrs and tightened STRC's BTC Credit by 10 bps."

The framework distributes assets across a monetary spectrum. Bitcoin occupies the defensive capital layer, while USDT — a zero-volatility instrument pegged to the dollar — handles fast, everyday payments. Between them sit two Strategy-engineered products: STRC, a Bitcoin-backed preferred stock whose dividend resets monthly at 12 percent annualized, and SR-strcUSX, a hybrid token combining fiat stability with debt-market yields. The top layer, Digital Equity, connects all levels into a single business.

The announcement arrives as Strategy has broken its "never sell" rule, liquidating 6,948 BTC worth $432.5 million this summer to fund dividends and maintain liquidity. The company's latest sale, disclosed Aug. 9, offloaded 1,690 BTC for $108.6 million at an average price of $64,262 per coin, with proceeds funding the repurchase of 1,152,020 STRC shares. CEO Phong Le said the company expects to return to net Bitcoin purchases by the end of 2026.

The Digital Credit Capital Framework

The new architecture traces back to the Digital Credit Capital Framework adopted in late June, which authorizes limited Bitcoin sales to fund preferred dividends, buybacks, and cash reserves when issuing equity looks less attractive. Strategy also sold 6,585,682 MSTR shares through its at-the-market equity program, raising $653.1 million, with $650 million routed into its USD reserve, which now stands at $4.65 billion.

The remaining Bitcoin stack cost $63.36 billion to build, an average of $75,385 per coin. Every disposal near current prices locks in a loss against that basis. STRC closed Friday at $95.01, up 1.16 percent, after sinking as low as $71.25 within the past year. Roughly $22 billion in MSTR issuance capacity remains untouched, while $785.2 million is still available in the preferred repurchase authorization.

The USDT integration comes as Tether's stablecoin supply has contracted by about $4 billion over the past 60 days, including an $870 million drop in the last 11 days, according to CryptoQuant data. Separately, Russia's central bank has approved Bitcoin, Ethereum, and USDT for retail trading on domestic exchanges under a new licensed crypto market regime.

Saylor's framework formalizes a two-tier crypto architecture: Bitcoin as the reserve asset, stablecoins as the transaction rail. For Tether, the endorsement from the largest corporate Bitcoin holder could reinforce USDT's position as the dominant payment stablecoin. For Strategy, the framework represents an attempt to transform its Bitcoin reserve from a passive holding into an active fintech instrument — a shift that will be tested as the company navigates its preferred stock repair and returns to net Bitcoin purchases.
