Cardano wallet SecondFi announces shutdown after hack attack
According to CoinDesk, the Cardano wallet SecondFi was attacked due to a vulnerability in its transaction signing software. A total of 16.1 million ADA (approximately $2.4 million) across 374 wallets was stolen, and the platform has announced permanent closure. The vulnerability allowed attackers to derive private keys from transaction data visible on-chain. The Cardano network itself was not affected, nor were hardware wallet users. An investigation by Groom Lake, a blockchain intelligence company hired by EMURGO, revealed that the primary attackers were sophisticated and well-funded. Some indications point to North Korea's Lazarus Group, but this has not yet been officially confirmed. SecondFi plans to release a wallet export tool in early August and launch a zero-knowledge recovery portal later in the month. EMURGO has established an asset recovery wallet, with the specific distribution time to be determined.
SecondFi to Gradually Shut Down Wallet Services After $2.6 Million ADA Theft
Cardano ecosystem wallet SecondFi announced that due to a cryptographic defect in its wallet software, approximately 16.1 million ADA (worth around $2.6 million) were stolen. The platform will gradually shut down the SecondFi and Yoroi wallet services. This incident has affected 374 wallets. SecondFi stated that an independent investigation by blockchain intelligence agency Groom Lake identified the attackers as a sophisticated external actor and found indicators potentially linked to North Korea's Lazarus Group, though attribution has not yet been confirmed. SecondFi is developing a recovery tool based on zero-knowledge proofs to help affected users recover assets while limiting the information that needs to be shared. The tool is still being tested and will undergo third-party audits before its planned release in August. SecondFi is also preparing a wallet export feature to allow users to migrate their assets to other services. The platform has not announced a direct compensation plan, nor has it indicated whether it will use its own funds to compensate users.
Midnight：Multiple Exchanges Including Binance Freeze Funds Involved in Cross-Chain Bridge Attack
the Midnight Foundation has provided an update on the handling of the cross-chain bridge attack event involving Wanchain Cardano and BNB. Multiple exchanges including KuCoin, Kraken, Binance, Bybit, OKX, Gate, and MEXC have coordinated risk control actions, temporarily freezing the involved accounts and associated addresses, adding the hacker wallet to a blacklist, and pausing NIGHT token deposits and withdrawals as needed to curb the transfer and cashing out of stolen assets.The Foundation specifically noted that this security incident is an isolated incident related to a third-party cross-chain bridge, and the Midnight mainnet and native NIGHT assets have not been affected. The project team continues to collaborate with major exchanges and ecosystem partners to advance traceability investigations, reminding the community to rely on official disclosures for information and to be cautious of misinformation.
Cardano Foundation: Volvo Group Once Created a Proprietary Cryptocurrency for Testing Supplier Payment Processes
the Cardano Foundation stated it has exchanged insights with the Volvo Group on the application of blockchain technology in the manufacturing industry. Ivan Branco, responsible for information management, artificial intelligence, and data analytics for Volvo Group’s Belgian truck operations, stated that Volvo once created a proprietary cryptocurrency to internally test the supplier payment process.Ivan Branco believes that while the relevant technology is already usable, organizational culture has yet to catch up, which is more challenging to address than the technical issues. He also noted that supply chain compliance is a significant application scenario for blockchain. Shared ledgers among suppliers can enhance the transparency of component origins and reduce compliance risks associated with using parts from sanctioned countries.
SecondFi Launches Asset Recovery Wallet Check Tool; Users Can Preliminary Check if Wallets Are Affected
Odaily, Cardano wallet service provider SecondFi has launched an asset recovery wallet check tool, allowing users to preliminarily check whether their relevant wallets have been affected by the previous security incident.SecondFi stated that the addresses currently displayed in the tool are based on the team's preliminary review data of the security incident and are not final. The list may not be complete and does not represent the final scope of recovery.
SecondFi: User Asset Repayment Expected to Begin in Approximately Two Weeks
Odaily, Cardano wallet service provider SecondFi has released an update on the security incident, stating that the team has completed the final balance snapshot of affected user assets. Several rounds of snapshots were continuously recorded during the incident response period to serve as the basis for subsequent asset recovery and reconciliation. SecondFi stated that the engineering and security teams are advancing the asset recovery plan. It is estimated that asset repayment can begin in approximately two weeks — one week allocated for finalizing a viable technical solution and another week for testing and review. The specific timeline may be subject to minor adjustments as progress unfolds. The platform will resume operations only after passing a comprehensive security review. Currently, users only need to submit a support request via the official website's ticketing system, with no additional action required.

Grayscale Files for First Zcash Spot ETF
Grayscale submitted the first application for a Zcash spot ETF on May 8.ZEC’s price once touched $600, pushing its market cap into the top 15 and surpassing Cardano. Multicoin Capital co-founder Tushar Jain noted that this move is driven by growing demand for privacy assets amid U.S. wealth tax legislative proposals. The SEC concluded its review of Zcash in January 2026 without taking enforcement action. Data shows that approximately 30% of ZEC’s supply is held in shielded addresses. Last week, U.S. Bitcoin spot ETFs saw $268 million in outflows, with some capital rotating into privacy and AI infrastructure tokens.

Cardano Enters Community Governance Era: Van Rossem Hard Fork Decided by Token Holder Vote
Odaily Odaily News The Cardano network completed the Van Rossem hard fork upgrade on July 18, upgrading the mainnet protocol version to 11 (Protocol Version 11). This upgrade not only brings smart contract performance optimizations but also marks the first time Cardano has completed a protocol upgrade led by its community governance system, rather than being directly driven by the founding team.Previously, Cardano hard forks were mainly coordinated by core organizations such as the engineering firm Input Output (IOG), which is responsible for development. In contrast, the Van Rossem upgrade was fully facilitated through Cardano's on-chain governance system for proposal, discussion, and voting, becoming the first major upgrade autonomously approved by network participants since Cardano entered the Voltaire governance era.According to on-chain data, the Cardano mainnet upgraded from version 10 in epoch 643 to version 11 in epoch 644, officially activating on July 18 at 21:44 UTC. The upgrade received final approval on July 13, requiring consensus from the representative bodies, the Constitutional Committee, and stake pool operators.Among them, DReps (Delegated Representatives), who vote on behalf of ADA holders in governance, approved the proposal with a 78.97% support rate, exceeding the 60% requirement; all seven members of the Cardano Constitutional Committee confirmed the upgrade complies with constitutional requirements; and stake pool operators, responsible for running the network's infrastructure, approved the upgrade with a 53.02% support rate.The Van Rossem upgrade primarily includes technical improvements such as optimizing the Plutus smart contract platform, reducing smart contract execution costs, and enhancing ledger validation rules. This upgrade also paves the way for the future Dijkstra-era hard fork and the Ouroboros Leios scaling solution.Ouroboros Leios aims to enhance the processing capacity of Cardano’s proof-of-stake consensus mechanism. It is expected to launch in 2026, potentially significantly increasing the network's transaction throughput while maintaining security.For ordinary ADA users, this upgrade does not bring significant operational changes; wallets do not need updating, and transfer methods and fees remain the same. However, in the long run, Plutus optimizations could lower the operational costs of decentralized applications (DeFi, NFTs, etc.), providing lower-cost infrastructure for ecosystem development.Cardano stated that the greatest significance of Van Rossem is not merely the technical upgrade, but the shift in governance model—the future direction of the network will be determined by community votes, rather than being entirely controlled by the founding team. This means ADA holders now truly possess governance rights to participate in protocol evolution for the first time. (CoinDesk)
Cardano Activates van Rossem Hard Fork
According to Cointelegraph, Cardano completed the van Rossem hard fork on Saturday, upgrading the mainnet to version 11. This upgrade is expected to reduce smart contract execution costs and lay the foundation for the subsequent Dijkstra era hard fork and Ouroboros Leios scaling upgrade. On-chain data shows that the network transitioned from protocol version 10 to version 11 at epoch 644. The report noted that this is also the first hard fork driven by the governance mechanism in Cardano's history.
