Aave has officially proposed a principal retention charitable donation layer, allowing users to continuously donate the generated income to charity while retaining control and liquidity of the principal.The proposal is currently undergoing a temp-check vote in the Aave governance forum. Its core aim is to address three major pain points of traditional charitable models: donors must permanently give up the principal, the funding flow of charitable organizations is unstable, and there is a lack of transparency in the use of funds.According to the proposal, users can deposit assets into yield-generating infrastructures like Aave, direct the earned income to donations, and withdraw the principal at any time.

According to Bloomberg, Iran has begun to launch a Bitcoin-based shipping insurance arrangement for the Strait of Hormuz to address the current high-risk navigation environment in the strait.Recently, Iran has introduced a maritime insurance platform called "Hormuz Safe," which provides digital insurance services for vessels passing through the Strait of Hormuz and allows payments in cryptocurrencies, including Bitcoin.Against the backdrop of escalating U.S.-Iran conflicts and risks in the Strait of Hormuz, the costs of war insurance for ships have surged significantly. Bloomberg previously reported that the insurance costs for some vessels crossing the Strait of Hormuz have now risen to about 5% of the vessel's value.

According to Hongxing News, the police in Linyi, Shandong recently dismantled a telecom fraud gang targeting minors, seizing about 140,000 yuan in illegal gains and 20,000 in virtual currency on site. Preliminary investigations have confirmed that the gang has carried out over 200 fraud cases nationwide, involving a huge amount of money.The police disclosed that the criminal gang used "free game skins and equipment" as bait to lure minors into using their parents' phones and remotely controlling the victims' devices through screen sharing to carry out transfer fraud. The stolen money was then laundered in batches through methods such as mobile phone top-ups, electricity bills, and property fee payments. The upstream fraud platform settled funds through virtual currency, and the suspects took about 20% of the fraud amount as their share. It is reported that the gang leader had previously traveled to Myanmar to engage in fraudulent activities and has strong counter-investigation experience. The case is still under further investigation.

This system is a set of smart contract mechanisms that allow ZKsync Governance to route and allocate protocol revenue and fees through its controllable on-chain mechanisms. ZKsync indicated that the relevant forum post has detailed the contract architecture, operational mechanisms, security measures, and deployment addresses of the system.

The People's Court of Gulou District, Fuzhou City recently concluded a dispute arising from investment in virtual currency. Chen transferred 480,000 yuan to Liu for foreign exchange wealth management, and Liu converted the funds into USDT and invested on an overseas platform. After the platform closed, Chen filed a lawsuit in court seeking a refund.The court reviewed the case and found that the transaction model formed a closed loop of receiving RMB, exchanging for USDT, cross-border transfer, and buying and selling foreign exchange, which constitutes a disguised foreign exchange transaction and is suspected of economic crime. The court ruled to dismiss Chen's lawsuit and transferred the relevant materials to the public security authorities for handling, with the Fuzhou Intermediate Court upholding the original ruling. The court reminded that investing in virtual currency violates relevant civil laws of public order and good morals, and any losses arising from this shall be borne by the investor.

After the Kelp security incident, Tether's asset interoperability protocol USDT0 announced details of its protocol security architecture, stating that the current system uses a proprietary DVN (Decentralized Verification Network) and has message veto power, while requiring 3 independent validators to reach a 3/3 consensus based on different codebases before cross-chain messages can be settled.The current validating nodes include USDT0's proprietary DVN, LayerZero, and Canary, with plans to expand to 4/4 and 5/5 verification mechanisms in the future. USDT0 also stated that all multi-signature transactions must undergo multiple reviews by internal teams, external security teams, and auditing institutions before submission for signing. Relevant contracts have been audited by organizations such as Guardian and OpenZeppelin and have launched a $6 million bug bounty program on Immunefi.

Polymarket announced the latest progress on feature updates, including the launch of measures to mitigate latency spam to ensure order placement and cancellation operations, fixing the "insufficient balance/authorization" error, and another core issue affecting limit buy orders is expected to be resolved in the coming days.In addition, Polymarket stated that it has identified and banned multiple clusters of ghost-fill accounts, all of which were created before the deposit wallet system went live. Any account exhibiting ghost-fill behavior will be identified and banned, and the deposit wallet system will also prevent non-compliant accounts from continuing to create new accounts in bulk. More updates will be released in the coming week to address previously outstanding issues.

LayerZero Labs posted on the X platform that the internal RPC used by LayerZero Labs was attacked by the Lazarus Group in the past three weeks, resulting in the compromise of the true source of its DVN (Decentralized Verification Network), while external RPC providers faced DDOS attacks. This incident affected 0.14% of applications and approximately 0.36% of asset value.LayerZero Labs stated that asset security is currently intact, and since April 19, over $9 billion in funds have been completed across chains through the protocol. In response to security risks, LayerZero Labs has stopped providing services for its DVN in a 1/1 configuration, and all default configurations for channels will be migrated to at least a 3/3 or 5/5 multi-DVN mode.Additionally, in response to an incident three years ago where multi-signature holders mistakenly used hardware wallets for personal transactions, LayerZero Labs has removed that signer and changed wallets, while also developing a OneSig custom multi-signature system. LayerZero Labs recommends that developers lock configurations to avoid relying on default settings and plans to launch an asset management platform Console to enhance security monitoring.

According to market news, LayerZero Labs co-founder and CEO Bryan Pellegrino had a heated debate with security researchers today in the ETHSecurity Community Telegram group. The core controversy includes: since LayerZero Labs can immediately upgrade a default library contract without a time limit to forge messages (similar to the case where rsETH was hacked), the LZ OFT, valued at over $3 billion, is recently at risk of being stolen; researcher Banteg pointed out that mainstream projects like Ethena and EtherFi were still using this default library contract weeks ago, and currently, there is still $178 million worth exposed to risk, with these funds coming from projects that are still using the default library.On-chain data shows that LayerZero Labs multi-signature signers participated in non-multi-signature activities such as meme coin trading, DEX exchanges, and cross-chain bridging, which means that the multi-signature keys in the formal environment were connected to websites, increasing phishing risks. Regarding the multi-signature signers of LayerZero using production environment keys for trading activities, Bryan confirmed that the related transactions were completed by members of the multi-signature team, but denied that it was "meme coin trading," explaining it as "testing PEPE on the LZ OFT token standard," and stated that the involved member has been removed. Bryan also suggested that project parties "directly fix configurations" instead of using default configurations to reduce risks. Banteg subsequently tagged a long list of LayerZero users still using the default library contract, pointing out that these projects should migrate to fixed configurations as soon as possible.

Paradigm general partner Dan Robinson proposed the "Proof of Address Control Timestamp" (PACTs) mechanism, aimed at providing a protection path for Bitcoin addresses against potential threats from quantum computing.This solution allows holders to generate address control proofs through BIP-322 and create on-chain commitments using a random salt value, completing time anchoring with OpenTimestamps to establish ownership proof without disclosing wallet information. If quantum-vulnerable addresses are frozen in the future through a soft fork, users can submit STARK zero-knowledge proofs to unlock their assets when spending. This mechanism also provides a potential recovery path for wallets derived from BIP-32, but its implementation still relies on Bitcoin introducing STARK verification capabilities and gaining community consensus.

Researcher Dan Robinson from Paradigm proposed a new scheme called PACT (Verifiable Address Controlled Timestamp), aimed at protecting long-dormant bitcoins, including Satoshi's early addresses, from future quantum computing attacks.This mechanism allows users to prove their control over an address through a timestamp without the need to transfer assets or expose on-chain behavior. Once future quantum attacks occur, assets can be recovered in a quantum-resistant version of the Bitcoin network based on that proof. Compared to mandatory migration schemes (like BIP-361), PACT avoids the privacy exposure issues caused by actively transferring assets, providing long-term holders with a more flexible preemptive protection path.

Curve Finance officially announced that it is introducing a bad debt recovery mechanism based on on-chain market mechanisms, allowing CRV-affected users in certain lending markets with bad debts to choose different recovery strategies: directly selling their claims to exit, continuing to hold and wait for potential recovery, or providing liquidity to earn fees and incentives. The core of this mechanism is to establish a trading pool between crvUSD and the tokens of the affected claims, allowing bad debt claims to be priced in the market and creating liquidity, thereby providing users with an immediate exit channel instead of relying solely on the final liquidation results.It is reported that after the cryptocurrency market crash in October last year, some lending markets under Curve Finance experienced bad debt issues, with various liquidity pools being impacted by severe price fluctuations and liquidity contraction, leading to some deposit users facing withdrawal restrictions and asset losses.Curve stated that the recovery mechanism will not eliminate losses or guarantee recovery, but will gradually reflect risks and recovery expectations through a market-oriented approach. Additionally, if the governance layer distributes rewards through the veCRV incentive mechanism, it will help enhance liquidity depth, improve exit conditions, and strengthen market pricing efficiency.

According to Fox News, the Federal Bureau of Investigation (FBI) has collaborated with law enforcement agencies in Dubai, China, and Thailand to conduct a large-scale multinational joint law enforcement operation, successfully dismantling at least 9 overseas cryptocurrency scam centers, resulting in the arrest of 276 suspects, with the amount involved reaching millions of dollars.In this operation, the U.S. District Court in San Diego has filed federal telecommunications fraud and money laundering charges against 6 suspects, including individuals from Myanmar and Indonesia, whose scam organizations operated under names such as "Sanduo Group" and "Giant Company." Dubai police arrested 275 suspects, while the Royal Thai Police separately apprehended 1 fugitive.The aforementioned scam network employed a "pig butchering" technique, gaining the trust of victims through fabricated friendships or romantic relationships, luring them to transfer funds to fake cryptocurrency investment platforms, and then laundering the money and transferring it to criminal accounts.This operation aligns with the executive order signed by Trump on March 6, 2026, aimed at combating overseas criminal networks that exploit U.S. citizens. The FBI's "Operation Level Up" has notified approximately 9,000 victims, recovering about $562 million in losses for U.S. citizens. The FBI urges victims to report through the Internet Crime Complaint Center (IC3).
