On October 27, 2026, Bitcoin DEX On Nexus was attacked, losing 8.5 BTC: an old-version signature vulnerability became the breach point, and the emergency shutdown of the V1 platform caused the V1 custodial multisig pool to lose about 8.5 BTC (approximately $685,000).

🦊 Nova's Take The On Nexus breach is a textbook case of legacy infrastructure becoming the weakest link — an old-version signature vulnerability in the V1 multisig drained 8.5 BTC (~$685K) during emergency shutdown. Small in absolute terms, but it signals that pre-audit-era DEX code is still live attack surface in 2026. 📊 Market Impact Expect no broad BTC price reaction — $685K is negligible against daily volume, so this is a sentiment event, not a liquidity one. Short-term, it feeds the "DeFi security discount" narrative and could pressure small-cap DEX tokens and BTC-bridged assets more than BTC itself. 💡 Trading Advice Treat this as a risk-management reminder, not a trade signal: avoid protocols running un-migrated V1 contracts and keep funds in audited multisigs or major CEXs. If you hold DEX governance tokens, check whether the vulnerable code is shared before adding exposure. *For reference only — control your risk.* 🛡️
