🔐 Crypto Hacks Cost $3.63B Across 245 Incidents in 19 Months
Crypto platforms lost $3.63 billion to security breaches across 245 incidents over a 19-month period, according to CoinGecko data.
The data highlights that the majority of attacks targeted vulnerabilities outside the scope of routine smart-contract audits — suggesting that standard security reviews are insufficient to cover the full attack surface facing crypto platforms.
🧩 Uniswap surges 32% on the week as DeFi tokens rally
Uniswap's UNI token has gained 32% over the past week, leading a broader recovery among DeFi-related assets. Bitcoin, meanwhile, has stabilized around $78,000.
Arbitrum's ARB and Curve's CRV posted sharp single-day gains of 24% and 15% respectively, pushing both tokens back into the top 100 by market capitalization. The moves signal renewed appetite for DeFi-native tokens after a prolonged period of underperformance relative to larger-cap assets.
🟠 Saylor essay backs self-custody while Strategy stacks Bitcoin debt
Michael Saylor has published an essay arguing that self-custody remains valid while simultaneously legitimizing the layered financial claims underpinning Strategy's Bitcoin acquisition model.
Strategy has built a capital structure — reportedly involving around $2 billion in financing loops — that issues equity and debt instruments backed by its Bitcoin holdings, creating multiple tiers of claims on the same underlying asset. Saylor's essay frames this as compatible with Bitcoin's self-custody principles rather than contradictory to them.
The argument matters as Strategy remains one of the largest corporate holders of Bitcoin, and its financing model is increasingly watched as a template for institutional Bitcoin treasury strategies.
🔐 Cronos halts network after $75M Tectonic exploit
The Cronos blockchain was temporarily frozen by validators after an attacker exploited lending protocol Tectonic in a Mango-style price manipulation attack.
The attacker inflated Tectonic's native TONIC governance token approximately 100-fold, then borrowed against the artificially inflated collateral. Total assets on the protocol plunged from roughly $121 million to around $3 million, with an estimated $75 million affected. Cronos validators halted the entire network to prevent further damage and freeze asset transfers.
The incident echoes the 2022 Mango Markets exploit on Solana, where a similar price manipulation technique was used to drain protocol funds. The attack highlights ongoing liquidity risks in DeFi lending markets built around thinly traded governance tokens.
Michael Saylor has signaled a potential Bitcoin purchase by Strategy, which would be the firm's first acquisition in roughly two months. The hint comes as Bitcoin rebounded from Friday's lows and approached $79,000.
Bitcoin dominance climbed above 60% alongside the recovery, while Strategy's market valuation expanded as the price moved higher. Saylor has previously used similar public signals ahead of confirmed purchases disclosed in regulatory filings.
