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. Data from DefiLlama shows that there were over 20 crypto vulnerability incidents in April alone, setting a monthly record. 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.

The meme coin application Zap posted on platform X that it will shut down on June 1. The team aimed last year to develop an application that allows anyone to register and purchase their first meme coin within 30 seconds. Although they achieved this goal, it did not gain the expected market appeal.They advise users to log into their accounts and export their private keys before the shutdown on June 1, and recommend importing them into Phantom to continue accessing all assets. After June 1, users who have not exported their private keys can still securely access their funds through Privy Home.

Ord.io will upload all historical voting records, replies, and public address information to GitHub to preserve relevant Bitcoin cultural data.

According to CoinDesk, the game public chain behind Axie Infinity, Ronin, will migrate from an independent sidechain to an Ethereum Layer 2 network through a hard fork on May 12, which is expected to result in approximately 10 hours of network downtime, during which all transfers, swaps, contract interactions, and on-chain gaming activities will be paused.This upgrade will introduce the OP Stack architecture and the "Proof of Distribution" allocation model, rewarding builders based on their actual contributions to the network, while significantly reducing the RON inflation rate from over 20% to less than 1%. Additionally, 90 million RON originally allocated for staking rewards will be moved to the treasury fund, and the market transaction fee will be increased from 0.5% to 1.25% to enhance security, scalability, and reshape the token economy.

According to official news, Tapp Exchange has announced that it will gradually cease operations. The protocol will remain fully available until May 31, 2026, and all user assets are secure and can be withdrawn at any time.Since its launch in June 2025, Tapp has built the first V4 style DEX on Aptos, continuously introducing the ve(3,3) voting mechanism, emission distribution, bribery infrastructure, and governance tools, transferring liquidity decision-making power to veTAPP holders.

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.

The blockchain gaming infrastructure Lattice announced that it will gradually shut down its operations after five years, with its Layer 2 network Redstone ceasing operations on May 16, 2026, at 07:59.Lattice reminds users to withdraw their funds before this deadline, especially assets in contracts such as the Uniswap pool. After the shutdown, only L1 withdrawal contracts will be deployed for external account balance withdrawals, and the funds in the contracts will be irretrievable.It is reported that Lattice was founded in 2021 and developed tools such as the MUD framework, Redstone chain, Quarry, and Dozer, but failed to achieve a sustainable business model. The team will use the remaining funds for the final project DUST autonomous world, but the scale has not reached a level to support the business, and they do not believe that VC financing is the right path.

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. The company emphasized that it is long-term profitable and financially robust enough to absorb this loss and will continue to strengthen cybersecurity measures, including internal access controls, monitoring, and emergency response mechanisms.

The Cosmos cross-chain smart contract platform Neutron tweeted that its network will shift to a long-term maintenance mode, prioritizing the protection of user, builder, and stakeholder asset security.

The team stated that despite significant innovations over the past four years, the recent market environment has been poor, and the lack of a viable long-term strategy led to this decision.

OKX founder and CEO Star responded to the "hacker attack incident involving a plugin vulnerability by the Wuhan Anshun Technology team" by stating, "The OKX Wallet security team has completed its investigation, and describing the original text as 'OKX wallet vulnerability' is inaccurate. Two points need clarification:This incident is not a security vulnerability of the OKX Web3 wallet. The attack method involved hackers controlling user devices through Trojan software, then stealing locally stored encrypted files and passwords by tampering with webpage JS code to implant hooks or by monitoring keyboard inputs.The OKX Web3 wallet is a 100% self-custody wallet. Private keys and passwords exist only on the user's own device, and OKX cannot access or control user assets. However, if the user's device has already been compromised by hackers, then no wallet—including MetaMask—can guarantee security. It's like a thief has already been able to operate your computer and see all your keyboard inputs.Users are advised to avoid installing software or plugins from unknown sources, regularly check device security, and properly protect their mnemonic phrases and private keys."It is reported that the Wuhan Anshun Technology team controlled a large number of user terminals to steal mnemonic phrases and remotely transfer digital assets, with the amount involved reaching 7 million dollars.
