Strategy and STRC both recover with the bitcoin move. Strategy shares hit a two-month high despite the company pausing BTC purchases for roughly that period, while STRC continued its climb back toward its $100 target. The correlation underlines how tightly Strategy equity tracks spot BTC sentiment rather than active accumulation news. theblock

Geopolitical risk from Strait of Hormuz closure adds a macro overhang. Iran has closed the Strait of Hormuz, with traffic reportedly falling to 6% of normal, driving oil higher and pushing US Treasury yields toward multi-year highs. For crypto, the read-through is mixed: macro stress has historically correlated with de-risking, but the current squeeze environment could absorb the shock if ETF inflows hold. cryptobriefing cryptobriefing

Grayscale Zcash Trust lists on NYSE Monday as ZEC trades near eight-year highs.

Solana cuts mainnet slot time to 350 milliseconds. The Solana Foundation pushed through the first reduction in slot time on mainnet, moving from the prior target toward an eventual 200ms goal.

The exchange, which declared it was winding down weeks ago, is now exploring a limited reopening alongside a creditor payout structure.

BounceBit shuts down its chain and migrates to BNB after a $3 million exploit. An attacker drained roughly 286.5 million BB tokens across nine wallets before block production was halted.

AI-assisted crypto crime up 40% year-on-year, per TRM Labs. TRM Labs reports attackers are increasingly using AI to surface overlooked vulnerabilities and infiltrate IT suppliers to crypto firms.

Senate schedules Clarity Act vote for 15 September. The chamber has pencilled in a vote date for the digital asset market structure bill, moving it from a standing item to an active legislative deadline.

CFTC leadership concedes existing rules are unfit for crypto markets.

The admission adds informal pressure behind the Clarity Act timeline but changes nothing operationally until legislation passes. cryptobriefing

MiCA scope creep toward DeFi lending vaults remains legally contested. Brussels is reviewing whether crypto lending products fall under MiCA’s perimeter, but permissionless lending vaults present a fundamental problem: there is no clear legal entity to regulate. The outcome will set a precedent for how broadly MiCA’s reach extends into protocol-level infrastructure across the EU. cointelegraph_regulation cointelegraph_defi
