Cronos halts after $75M Tectonic exploit as Monero surges 5% and Bitcoin holds near $78K

The day's dominant story was the Cronos blockchain halt. A $75 million exploit of Tectonic, a lending protocol on the Cronos network, forced the chain to suspend operations entirely — an extreme response that signals the severity of the breach. CRO fell 6.92%, the steepest single-day drop among tracked assets, as traders exited positions in the Crypto.com-linked ecosystem. Network halts of this kind are rare; the last comparable event was the Solana outage in 2022. Beyond Cronos, the broader market drifted lower on moderate selling pressure. Solana fell 2.95%, Dogecoin dropped 3.00%, and XRP slid 2.34%, though none of these moves had a clear individual catalyst — they appear to reflect general risk-off sentiment following the Cronos news. Bitcoin held up better than most, slipping just 0.80% to $78,013. Two factors likely cushioned the decline. First, Strategy announced it had resumed Bitcoin purchases after a two-month pause, acquiring 4,603 BTC for $369.7 million last week — a visible institutional demand signal. Second, market fears of a September Fed rate hike appear overstated: actual probability sits at 58%, not the 90% figure circulating in some commentary, which removed one layer of macro pressure. Monero gained 4.95% with no clear catalyst in the available data — the move stands out against the day's otherwise negative tape but lacks an identifiable driver.

• –Strategy now holds 845,050 BTC in total after resuming purchases for the first time since late June, adding 4,603 BTC for $369.7 million last week.
• –Robinhood Chain surpassed Ethereum and Base in daily fee revenue, driven by memecoin trading volume — a notable shift in where on-chain activity is concentrating.
• –Russia's Sberbank plans to accept ETH and USDT as collateral for crypto-backed loans, extending institutional adoption of Ethereum into the Russian banking sector.
