The co-founder of the Solana ecosystem DeFi project Ranger Finance, cobra (@barrett_io), posted on the X platform that Ranger Finance is gradually shutting down. The project took on business beyond its sustainable capacity, and the founder invested personal funds to maintain operations, but delays in financing led to the accumulation of bills. Ultimately, the financing was unsuccessful, and the raised funds were returned.The team is trying to fairly pay employees and suppliers with the remaining two months of operating funds, but it is insufficient to cover all expenses. The treasury liquidation was unexpected and severely impacted budget decisions. Subsequently, the Drift attack incident depleted the remaining funds and personal capital. Treasury users affected by the Drift attack will receive recovery tokens when distributed by the Drift team. The founder stated that in hindsight, the project should have been shut down earlier and apologized for this.

According to official news, the smart contract auditing platform Code4rena has announced that it will gradually cease operations, and the Web3 security company Immunefi will take over its clients and security researchers. Code4rena posted on social media that it has made the decision to shut down and stated that all ongoing competitions and bounty activities will be completed as usual, and existing collaborations will be "properly concluded." Immunefi stated that it will assist in migrating Code4rena's bounty projects, reward structures, and researchers to its platform.Code4rena is known for its "competitive auditing" model, where independent researchers compete to find vulnerabilities in smart contracts for rewards. This shutdown comes less than two years after blockchain security company Zellic acquired Code4rena in 2024. Previously, Code4rena raised $6 million from Paradigm in 2023 for auditing incentives and platform expansion.This shutdown comes at a difficult time for DeFi protocols and the security sector.

JPMorgan analysts believe that ongoing DeFi security incidents are limiting major institutional investors from entering the market. Meanwhile, the total value locked in DeFi has decreased from about $160 billion in October to approximately $83 billion currently.

According to DL News, the major Russian cryptocurrency exchange Grinex has ceased operations due to a suspected major cyber attack, reportedly resulting in losses exceeding 1 billion rubles (approximately 13 million USD). The platform claimed on Telegram that the attack showed "signs of involvement from foreign intelligence agencies."Grinex is the successor to the previously sanctioned and closed Garantex exchange, providing a financial channel for the Russian economy to evade sanctions. Experts point out that Grinex's closure is not only due to the hacker attack itself but, more importantly, it removes the trading platform that Russian businesses relied on to convert rubles into usable international currencies, causing "serious damage" to the infrastructure that allows Russia to evade sanctions, making it more difficult for the Russian economy to escape the pressure of sanctions.The exchange was sanctioned by Western authorities such as the U.S., U.K., and the European Union in August 2025. Meanwhile, the Russian economy continues to weaken, with Putin revealing that GDP fell by 1.8% in January-February this year, and maritime oil exports may drop to their lowest level since 2023.

According to the official announcement from Seamless Protocol, the Base chain DeFi lending protocol Seamless Protocol, which has been operating for over two and a half years, has announced its official shutdown. The protocol's UI will go offline on June 30, 2026, at which point team support will also cease. Users must withdraw all assets through the UI before this date; otherwise, they will need to manually interact with the contract, which is complex and lacks technical support.The team stated that the core reason for the shutdown is that leverage tokens failed to find a product-market fit—structural liquidity shortages in the DeFi lending market have prevented the product from scaling, compounded by fluctuations in lending rates eroding returns, and the protocol also lacks a sustainable revenue path.The team also pointed out that the DeFi market trend is shifting towards actively managed vaults, which fundamentally diverges from its non-custodial, fully automated product positioning. Additionally, the team will submit a governance proposal to allocate the remaining assets in the DAO treasury to SEAM token holders.

The People's Court of Qinzhou District, Tianshui City, Gansu Province recently tried a criminal case involving virtual currency, where the defendant, through a "high-paying errand" job, knowingly withdrew a total of over 390,000 yuan within 7 days in areas without surveillance, and converted the funds into virtual currency to transfer to their superior, profiting 21,500 yuan in the process.The court determined that the defendant constituted the crime of concealing and disguising criminal proceeds, sentencing them to two years and four months in prison and imposing a fine of 10,000 yuan, as well as ordering the return of illegal gains. The judge reminded that offline cash withdrawals have become a key link in "laundering" telecom fraud proceeds, and that "errand cash withdrawals" and "high-paying daily settlements" are often part of the fraud chain. The public should be vigilant against behaviors such as cash collection, transfers, and assisting in fund transfers to avoid becoming accomplices in crime.

Bitcoin payment service provider Bitrefill disclosed on platform X that it suffered a cyberattack on March 1, 2026, resulting in a customer data breach. The attack originated from a compromised employee's laptop and allowed the attackers to access certain databases and cryptocurrency wallets.Investigations revealed that the attack method was highly similar to past attacks on cryptocurrency companies by the North Korean DPRK Lazarus/Bluenoroff hacker group. Approximately 18,500 purchase records involved limited customer information (email, cryptocurrency payment addresses, and IP metadata), with about 1,000 records having customer name information stored in an encrypted format, but potentially accessible. Bitrefill stated that customers do not need to take special actions but are advised to be vigilant for unusual information.Bitrefill further added that it has currently shut down related systems for isolation and is collaborating with security experts, on-chain analysts, and law enforcement. Operations have nearly returned to normal.
