A July 30 arXiv preprint links malicious smart contracts to 5,742 victims and $3.48M losses, showing how they deceive wallet previews by displaying small gains while diverting funds to attackers.
Exploring the basics and value of Non-Fungible Tokens (NFTs), their creation, investment potential, and future in art and collectibles.
TRM Labs reported a record 207 crypto hacks in H1 2026, yet total losses fell to $972 million. This shift highlights that while more protocols are targeted, significant losses stem from operational system compromises like key management and custody, not just smart contract exploits.
La sécurité des cryptomonnaies repose sur la gestion des clés privées, qui sont le point faible principal. 40% des pertes dues aux hacks proviennent de problèmes de clés privées, non de failles de smart contracts. Des milliards de dollars ont été perdus.
Aztec's deprecated infrastructure experienced a second exploit, losing $2.15 million in ETH, DAI, and renBTC. This follows a similar incident last Sunday and highlights growing concerns about the security of abandoned smart contract infrastructure in the crypto space.
Crypto lending protocol Radiant Capital is winding down operations after a $50 million exploit by North Korea's Lazarus Group in October 2024. The protocol will enter a "maintenance state" but will cease development and upgrades.
This opinion piece examines whether DeFi has failed to deliver on its original promises of user sovereignty, security, and decentralization. The author argues that while DeFi proved public settlement and transparent ledgers can work at scale, it has struggled with security breaches totaling billions, new attack vectors including AI, and a shift toward institutional adoption that leaves the permissionless vision behind. The piece analyzes hack data from 2021-2025, compares DeFi loss rates to TradFi, and uses the Aave rsETH incident as a case study of how mature DeFi crisis management still requires centralized governance intervention.
Decentralized finance (DeFi) faces a critical question in 2026: is its original vision of user-held keys and open markets still achievable? Despite early promise, DeFi has grappled with exploits, failures, and a shift from true decentralization to new forms of trust and risk.
I believe the hardest question for DeFi in 2026 is whether the original dream is still alive. The collective bargain was simple. Users would hold their own keys. Code would execute the rules. Markets would stay open. Ledgers would be visible. Intermediaries would lose power because financial services could run on public smart contracts rather […] The post DeFi losses are now 8,500% higher than TradFi breaches per dollar moved appeared first on CryptoSlate.
Umbra, a privacy-focused crypto protocol, took down its front-end website after discovering around $800,000 in stolen funds was moved through it by hackers connected to recent high-profile exploits. The action comes days after the Kelp protocol was exploited for over $280 million, which security researchers suspect was carried out by North Korean hackers. Umbra stated it has been working with security researchers and noted that all funds moved through its protocol can be identified. Roman Storm, co-founder of Tornado Cash, warned that changing the front end may not be enough to avoid regulatory scrutiny, citing his own conviction for operating an unlicensed money transmitting business.
