Eko Protocol Restores Aptos Services After $816,000 Hack, Completes Security Audit

BitcoinWorld Eko Protocol Restores Aptos Services After $816,000 Hack, Completes Security Audit Eko Protocol, a decentralized finance (DeFi) project built on the Aptos blockchain, has announced the restoration of its services following a security breach last month that resulted in losses of approximately $816,000. The project confirmed via its official X account that lending, liquid staking, and vault operations are once again active on the platform. Service Restoration and Security Audit According to the announcement, Eko Protocol has completed a comprehensive security audit of all smart contracts, including those governing administrative privileges. The audit found no remaining vulnerabilities, allowing the team to safely resume operations. The project stated that all affected services are now fully functional, marking a significant step toward recovery after the exploit. Background of the Hack The hack, which occurred in early February, targeted Eko Protocol’s smart contracts, draining approximately $816,000 in user funds. The incident was part of a broader wave of DeFi exploits that have plagued blockchain networks in recent months. The project paused services immediately after the attack to contain the damage and initiate an investigation. Implications for Aptos DeFi Ecosystem The restoration of Eko Protocol’s services is a positive signal for the Aptos DeFi ecosystem, which has been working to rebuild user confidence after several security incidents.

Zcash Fixes Critical Orchard Vulnerability As ZEC Holds $600 Support

Zcash has patched a dangerous vulnerability in its privacy-focused infrastructure that could have enabled double-spending, deploying an emergency network upgrade to prevent exploitation. Related Reading: Ethereum Ready For The ‘Final Dip’? Analysts Call For New Lows As Price Retests $1,900 Zcash Fixes Critical Bug With Emergency Upgrade On Wednesday, the Zcash Foundation revealed that developers had fixed a serious vulnerability in its Orchard shielded pool, which could have allowed invalid state transitions, potentially enabling double-spending within the pool. According to the report, Zcash researcher Taylor Hornby, who is conducting an ongoing protocol audit on behalf of Shielded Labs, discovered a critical soundness vulnerability in the Orchard zero-knowledge proof circuit on May 29 and disclosed the issue to Zcash Open Development Lab (ZODL) core engineers that same day. “A soundness vulnerability is one that could allow the system to accept something it should reject. In this case, successful exploitation could have allowed the Orchard pool to accept invalid state transitions, potentially permitting double-spending of funds within Orchard, though with no ability to inflate the total ZEC supply, which is protected by Zcash’s turnstile mechanism,” the foundation explained. After identifying the vulnerability, Zcash developers, miners, and infrastructure operators coordinated privately to prepare a fix, keeping details confidential to avoid potential exploits. The first soft fork attempt faced technical challenges, but engineers quickly released a revised patch that successfully activated on June 2, temporarily disabling Orchard-related transactions. On June 3, the network completed a full hard fork upgrade, NU6.2, restoring Orchard functionality with the corrected code and permanently resolving the vulnerability. The Foundation said there was no evidence that the bug was exploited, as no unauthorized value creation was detected. In addition, they affirmed that the total ZEC supply remains safe and the issue did not affect the privacy of funds held in any Zcash pool. ZEC Holds Key Support Amid Network Confusion Following the upgrade, news that the network was offline circulated on social media, creating confusion among community members. Some reports claimed that Zcash had failed to produce blocks for over four hours. However, Mert Mumtaz, CEO of Solana infrastructure firm Helius, dismissed these reports, affirming that the network was never down and that explorer apps were connected to a bad node. In a series of X posts, Zcash blockchain explorer CipherScan confirmed the issue, explaining that its nodes were upgrading to support the recent NU6.2 network upgrade. “What actually happened: Zcash pushed a coordinated network upgrade (NU6.2) that required all node operators to update. During that transition, some block explorers, including ours, showed stale or missing data while we upgraded,” the post stated. “That’s the explorer being out of sync, not the blockchain being broken. Important distinction. (…) Block explorers are just readers. They pull data from a node, parse it, and display it. If the node is upgrading or resyncing, the explorer goes stale,” the explorer continued.

Notably, the cryptocurrency has soared roughly 20% over the past two days while most of the market bled. After failing to reclaim the $630 local resistance, the cryptocurrency dropped toward the $600 support, briefly falling below it before bouncing again. As of this writing, Zcash trades at $612, a 9.5% increase in the weekly timeframe. Featured Image from Unsplash.com, Chart from TradingView.com

Drift to Rebrand as Solana Perp Exchange After $295M Hack, Appoints New Security Lead

BitcoinWorld Drift to Rebrand as Solana Perp Exchange After $295M Hack, Appoints New Security Lead Drift (DRIFT), the decentralized exchange that suffered a catastrophic hack of approximately $295 million in April, has announced a comprehensive rebranding strategy. The company will relaunch as a Solana-based perpetual futures exchange, with a renewed focus on security and user compensation. Rebranding and New Focus In a statement released today, Drift confirmed that it will rebrand as a USDT-based perpetual futures trading platform. All revenue generated by the new platform will be directed into a dedicated fund to compensate users affected by the April exploit. The move marks a significant strategic pivot for the protocol, which was previously known for its broader decentralized finance (DeFi) offerings on Solana. New Leadership and Technical Support To spearhead this security overhaul, Drift has appointed Noah Prince as its new Protocol Lead. Prince previously served as the engineering lead at Helium Protocol, a decentralized wireless network, where he gained a reputation for robust system architecture. Additionally, the exchange will receive technical support from team members at Gauntlet, a firm specializing in decentralized finance modeling and risk management. Gauntlet’s involvement is expected to provide advanced stress-testing and economic security analysis for the new platform. Why This Matters for Users and the Solana Ecosystem The April hack, one of the largest in Solana’s history, severely damaged user trust and raised questions about the security of DeFi protocols. Drift’s decision to rebrand entirely, rather than simply patch the existing system, signals a recognition that a fundamental change in approach is necessary. For the Solana ecosystem, the successful relaunch of a secure perpetual futures exchange is critical for restoring confidence in the network’s ability to host high-value financial applications. The focus on a single product—perpetual futures—also suggests a move toward specialization, which could help Drift compete more effectively against established players like dYdX and GMX. User Compensation Plan Drift has stated that details of its user compensation plan will be released at a later date. The company has not yet specified whether compensation will be paid in the form of native tokens, stablecoins, or a combination of both. The decision to allocate all future platform revenue to the compensation fund is a notable commitment, though the timeline for full repayment remains unclear. Conclusion Drift’s rebranding as a Solana-based perpetual futures exchange represents a high-stakes attempt to recover from one of the most significant security breaches in DeFi history. With new leadership from Helium and technical backing from Gauntlet, the platform is betting on a security-first approach to win back user trust. The coming weeks will be critical as the company unveils its compensation plan and demonstrates whether its new architecture can withstand the scrutiny of a skeptical market. FAQs Q1: What exactly happened in the Drift hack? A: In April, Drift suffered a security breach that resulted in the loss of approximately $295 million in user funds. The exploit targeted vulnerabilities in the protocol’s smart contracts, leading to the unauthorized withdrawal of assets. Q2: When will the new Drift platform launch? A: Drift has not announced a specific launch date for the rebranded perpetual futures exchange. The company is currently in the development and security audit phase, with details expected to be shared in the coming months. Q3: Will all affected users be compensated? A: Drift has committed to using all revenue generated by the new platform to fund user compensation. However, the exact details of the compensation plan, including eligibility criteria and payout schedule, have not yet been released. The company has stated that this information will be provided at a later date.
