Empowa Suffers Unauthorized Transfer Incident, Approximately 4.24 Million EMP and 143,700 ADA Stolen
Empowa, a Cardano ecosystem project, disclosed two interrelated unauthorized asset transfer incidents across its three project wallets. Between November 2025 and June 2026, approximately 143,710 ADA were transferred out of one project treasury wallet in 18 transactions. The corresponding Midnight airdrop for this wallet was also registered and claimed by an unknown party using the private key, with approximately 36,000 NIGHT already transferred away. From June 2026 to August 2026, a cumulative total of approximately 4.24 million EMP tokens were transferred out of the other two project wallets, with portions sold via platforms such as Minswap and VyFi. Empowa stated that the funds from both incidents ultimately flowed into the same intermediate wallet, indicating they are controlled by the same party, although the identity of the individuals operating these private keys cannot currently be confirmed. The team has hired a professional blockchain investigation firm and plans to seek KYC information from the centralized exchange where the related funds ultimately entered.
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.
Analysts: ADA still faces selling pressure after a 10% weekly decline, with $0.24 as key support
Crypto analyst AI stated in a post that Cardano (ADA) futures demand is cooling, with open interest declining by 9% over the past week from $1.99 billion to $1.81 billion, indicating traders are reducing leveraged exposure. Meanwhile, whales also appear to be taking profits, having reduced their holdings by approximately 90 million ADA valued at roughly $22.5 million since September 20, further adding to recent selling pressure. AI further noted that the ADA daily chart generated a sell signal on September 26, followed by a 10% drop, suggesting the pullback may not be over yet. A parallel channel on the daily chart shows that $0.24 is a key mid-level support level; if breached, ADA could slide further toward the channel's lower boundary at approximately $0.21. If $0.21 holds, it could present the next buying opportunity, with upside targets looking toward the channel's upper boundary at around $0.28.

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.

Operations Ceased, SecondFi Wallet Migration Tool Launches August 13, Affected Asset Recovery Portal Expected by September 10
: Cardano ecosystem wallet project SecondFi has announced the launch of a wallet migration tool and revealed a recovery plan for assets affected by the June 2026 security incident. As the project will cease operations, users are required to migrate remaining assets still held in SecondFi wallets. The migration tool is expected to go live on August 13, supporting the transfer of eligible ADA, Cardano native tokens, and NFTs to new Cardano wallets created with service providers of the users' choosing. Currently, the tool only supports Cardano network assets; non-Cardano assets must be transferred separately through corresponding network and wallet processes. SecondFi stated that the migration tool has passed an independent security assessment by security firm Bitdefender. For affected assets, SecondFi plans to launch a recovery portal before September 10, where users can verify wallet ownership via zero-knowledge proofs (ZK Proof) and submit asset claims. SecondFi reminds users to only rely on information published through official channels, including @secondfiapp, @secondfi_jp, and the official support website, to guard against phishing sites and impersonating accounts.
