Echo Base is an institution focused on stabilizing digital asset companies, assisting in the formation of the BitMart Creditors' Committee, representing users holding frozen assets, and hiring legal advisors to evaluate recovery plans, including applying for bankruptcy proceedings without financial support. Echo Base had proposed a funding plan of up to $10 million to support BitMart in submitting a pre-negotiated bankruptcy application, but received no response from BitMart.Echo Base stated that the relevant actions stem from BitMart's failure to respond to the restructuring proposal and user withdrawal requests. Sonn Law Group has initiated an investigation for users with frozen assets of $500,000 or more at BitMart, assessing potential claims and asset recovery plans. Echo Base CEO Roshan Dharia stated that BitMart's employee plan can only sustain operations until January 2027, and the longer the delay, the fewer viable options there will be.

According to Bitcoin News, the Bitcoin mining pool OCEAN has officially stopped supporting the BIP-110 fork chain, citing limited mining activity and the transition to the Blake2b proof-of-work mechanism. OCEAN stated that it will not adopt or support the BIP-110 hard fork and will not continue to pay BIP-110 block rewards.The BIP-110 chain stalled after the user-activated soft fork attempt failed on August 8, and the mining rewards post-fork became unusable due to not reaching 100 confirmations. OCEAN stated that these rewards have been permanently frozen at BIP-110 block 961,639. Miners hoping to continue supporting BIP-110 have been directed to CONVOY Mining, which plans to support the Blake2b hard fork and continue the BIP-110 share record.

According to BeInCrypto, the digital campaign of Brazil's "pro-Bitcoin" presidential candidate Renan Santos has been suspended, with 3.3 million reais (approximately 600,000 USD) of public campaign funds frozen and 16 campaign social media accounts restricted.Weeks before this ruling, Santos had just supported the establishment of a national Bitcoin reserve. His candidacy has not been revoked, but his online reach and funding have been severely impacted.

On August 20, MANTRA Chain released a complete review report of the security incident, confirming that the attacker exploited an unsigned integer underflow vulnerability in the balance accounting layer of the upstream dependency cosmos/evm, unauthorizedly transferring a total of 720,923,967.99 MANTRA from two addresses, valued at approximately 3.6 million dollars based on the price before the attack. Among them, the attacker transferred 600,000,035.56 MANTRA from the on-chain burn address and 120,923,932.44 MANTRA from a genesis-era multi-signature address related to an early incentive program.MANTRA stated that this incident did not involve the leakage of validator keys, administrator privileges, governance control, or multi-signature signers; the attacker did not require privileged access and could complete the attack solely through unauthorized contract deployment and self-funded wallets. The first abnormal transfer occurred at 19:06 UTC on August 20, when the attacker transferred approximately 600 million MANTRA from the burn address; subsequently, at 22:59 UTC, another transfer of approximately 120.9 million MANTRA was made. The chain subsequently stopped operating at 23:13 UTC and resumed after upgrading to v8.4.0. The entire network interruption lasted for 30 hours and 13 minutes.This vulnerability was not an issue with MANTRA's self-developed code but originated from the cosmos/evm module, which is responsible for providing EVM functionality on the Cosmos SDK. The vulnerability allowed the attacker to execute unsigned balance deductions without checking if the balance was sufficient, causing an overflow of values and bypassing normal account authorization logic. MANTRA stated that as of today, no funds have been recovered, with approximately 37.96 million MANTRA (accounting for 5.27% of the total transferred) still remaining in the attacker's address, which has been frozen due to the chain's suspension and v8.4.0 restrictions. The remaining funds have flowed to related trading platforms, and the recovery efforts have entered the law enforcement investigation stage. In the future, monitoring of accounts that cannot normally authorize transfers, burn addresses, and other historically "non-transferable" addresses will be strengthened, and efforts will be made to promote improvements in the security vulnerability disclosure process within the Cosmos ecosystem.

MANTRA Chain tweeted that it has noticed events affecting MANTRA Chain and has temporarily suspended the operation of the chain as a precautionary measure while conducting an investigation. Currently, all endpoints and transactions have been frozen.This means that deposits to MANTRA Chain and withdrawals from the chain are temporarily affected. If users are unsure of the specific impact on a particular transaction, it is recommended to pause operations and wait for further notice. The team stated that there is currently no fundamental cause or recovery timeline to announce and will update as soon as verified information is obtained through official channels, reminding users to rely only on official MANTRA channels for updates.

According to KOL Kuai Dong (@_FORAB), several cryptocurrency practitioners reported this morning that their addresses on other exchanges inexplicably received small deposits from HTX exchange, and shortly after receiving them, their accounts were frozen. Previously, several exchanges, including Binance and OKX, announced that in response to sanctions from the EU and the UK, they would no longer process deposits and withdrawals from HTX, otherwise accounts could be forcibly frozen. Some users in the community claimed that this action is similar to "address poisoning," which could trigger KYT/AML risk control on other platforms.However, HTX market manager MollyFu stated that the official side absolutely did not engage in such behavior; it is either a misunderstanding or someone is deliberately causing trouble. The platform has been processing tens of thousands of deposits and withdrawals daily in the past two days, and accounts are normal. They will not randomly airdrop to users on other platforms; if testing is conducted, it will only be done on a small scale through their own accounts. HTX stated that they have held an internal meeting to discuss the matter and are quickly investigating the cause, promising to provide an explanation to the community.

According to Livecoins, the Joint Task Force Against Organized Crime in Rondônia, Brazil (FICCO/RO) executed arrest and search warrants against a gang suspected of electronic fraud and money laundering. The criminal organization is accused of using cryptocurrency exchanges to hide illegal funds transferred from the original victims' accounts.A case investigated in 2025 resulted in losses of approximately $5.74 million. The court has issued 8 preventive arrest warrants and 18 search warrants, and authorized the freezing of related assets such as cryptocurrency exchange and bank accounts. In addition to targeting securities accounts, the law also mandates the seizure of vehicles and boats belonging to the individuals under investigation.

According to monitoring by Bitcoin News, Galaxy Research stated that the largest known COLDCARD theft involved 1159 BTC, spread across seven attacker addresses, which have not yet been utilized, with 0 BTC cashed out or transferred through mixers. The related BTC was stolen within 41 minutes, but approximately 600 attacker addresses have been flagged by law enforcement, exchanges, and blockchain analysis companies.Meanwhile, a smaller-scale attacker seems to have begun laundering funds. On-chain analysts tracked 64 BTC entering a mixer, of which only about 10 BTC were initially mixed, and 54 BTC were returned as change, which was then split into outputs of about 7 BTC for further mixing. Analysts noted that these unusually large outputs remain easy to trace, making this laundering attempt relatively transparent.

On-chain yield platform Altura announced that it originally planned to purchase USDT using fiat funds from its Altura bank account through over-the-counter trading partners, but the bank account holding the relevant funds has been temporarily frozen by the bank. Screenshots show that the frozen amount is approximately £16.446 million, about $21.88 million, and this plan has therefore been hindered.Altura stated that it has communicated with the bank regarding this matter, and the bank has requested that it wait for the review to be completed, stating that it will contact them separately if additional materials are needed. The current situation is completely beyond Altura's control, and they must wait for further responses from the bank. Altura also announced that due to limited team resources, it will suspend community chat functions to focus on addressing the current issues, and it promises that subsequent developments will be promptly communicated through its official X account, Telegram channel, and Discord, while urging the community to avoid speculation until official confirmation is received.

According to Jinshi reports, U.S. Treasury Secretary Basant stated that $130 million in cryptocurrency wallets related to the Iranian Islamic Revolutionary Guard Corps has been frozen.

Token Pocket's Chief Business Officer Michael stated that the mnemonic phrase of the Robinhood founder was leaked during a live broadcast. After hackers gained control of the address, they used that address and associated addresses to buy a large amount of the Meme coin at $1, prompting thousands of investors to follow suit, rapidly increasing the market value of the token from about $500,000 to $14 million in a short period.Subsequently, the price of the $1 token fell sharply, with a trading volume of about $20 million within just two hours. After the related addresses were frozen, the hackers quickly moved to the BNB Chain (BSC), using that address and its associated addresses to issue new tokens, and created trading hype through self-buying and selling, ultimately executing a sell-off to cash out. Robinhood's RPC has frozen that address, and nodes do not allow transactions sent from that address to be packaged, so transfers and trades cannot be conducted.

According to Vietnam's Youth Newspaper, the Ministry of Public Security of Vietnam recently held a press conference to report the latest investigation results of the ONUS cryptocurrency platform fraud case. More than 350 kilograms of gold and silver have been seized, transactions involving 8 properties valued at 20 trillion Vietnamese dong have been frozen, and transactions of over 300 involved bank accounts have been suspended.On March 23 of this year, the police filed criminal charges against 8 defendants, accusing them of using computer networks and telecommunications networks to commit property appropriation and money laundering. Since 2018, the individuals involved have taken advantage of the public's lack of understanding of cryptocurrency, creating digital accounts through applications and packaging them as virtual currency. They established trust and attracted investment through circular buying and selling among affiliated companies, thereby committing fund appropriation, with a total sale of cryptocurrency valued at over 70 trillion Vietnamese dong from 2018 to 2021.The case involves numerous individuals and users, with approximately 5 million user accounts opened. The police have received over 2000 reports from citizens. The public security authorities are investigating the possible accomplice responsibilities of KOLs and other internet celebrities and continue to make every effort to recover the embezzled funds.

According to Bloomberg, the Federal Police of Brazil simultaneously carried out law enforcement actions in multiple locations in São Paulo to implement the sanctions resolution previously issued by the U.S. Department of the Treasury, targeting cross-border money laundering gangs serving the Brazilian gang "First Command of the Capital (PCC)."This operation executed 11 temporary arrest warrants and conducted 13 searches and seizures, involving two core individuals who have been placed on the sanctions list by the U.S. authorities. As ruled by the court, a total of 1.04 billion reais (equivalent to 200 million dollars) in funds, physical assets, and cryptocurrencies associated with the individuals involved have been frozen.The individual involved, Stella Stefanie Nunes Henrique de Oliveira, has been arrested by the police, while another suspect, Victor Henrique de Oliveira Shimada, is currently at large. U.S. authorities accuse the two of establishing multi-layered financial channels, relying on cryptocurrency transfers, cash transportation, and large transfers between public and private accounts to move criminal proceeds. The suspects will face multiple charges including conspiracy, money laundering, and illegal cross-border transfer of funds.

The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) has added 134 cryptocurrency wallet addresses belonging to the terrorist organization ISIS-K to the Specially Designated Nationals sanctions list. The stablecoin issuer Tether has frozen the funds of 131 of these Tron addresses, while the remaining 3 sanctioned addresses are located on the Monero network.

According to Decrypt, the Dutch Public Prosecution Service has applied to the Rotterdam court to declare the cryptocurrency platform Knaken and its affiliated payment institution Stichting Knaken Payments bankrupt, stating that this move is in the "public interest."Knaken has ceased operations since early June, leaving approximately 30,000 users unable to withdraw funds from the platform. The prosecution stated that the platform did not obtain the license required by the EU's Markets in Crypto-Assets Regulation (MiCA) from the Dutch Authority for the Financial Markets (AFM), and the liquidation process lacks orderly management, having stopped payments to customers and allegedly advised users not to file compensation claims.Meanwhile, the Dutch Financial Intelligence and Investigation Service (FIOD) has launched a criminal investigation and searched relevant locations on Monday, seizing laptops, mobile phones, and some company assets, with no arrests made so far. If the court approves the bankruptcy application, the court-appointed bankruptcy administrator will take over the company's assets and be responsible for determining the repayment arrangements for customers and other creditors.

According to The Block, Sovright (the nonprofit successor organization related to Electric Coin Company for Zcash development) has officially released a wallet recovery tool named "Argos," aimed at helping early Zcash users recover funds that have been "stuck" due to the discontinuation of the old version of ZEC Wallet Lite in 2022.Sovright's Executive Board Chair Michelle Lai stated that Argos can recover affected assets as long as users still hold the old wallet mnemonic phrases, but since it only involves specific shielded addresses, the scale of the impact cannot be precisely estimated. However, it is estimated that the "amount is considerable," primarily concentrated among early long-term holders.She referred to the issue as a "technical pitfall" that the community has long failed to address, which, although not prominent, continues to erode user trust. Sovright currently consists of only three core members, all from the former Bootstrap system. The team is also testing a privacy-focused Zcash mining pool to reduce hash power centralization and enhance network decentralization.The governance structure of the organization has undergone significant adjustments, with Electric Coin Company employees collectively leaving to establish a new entity, Zcash Open Development Lab (ZODL), which has received support from institutions such as Paradigm and a16z, focusing on the development of Zcash-related products.Sovright emphasizes that there is no antagonistic relationship with ZODL and states that it will continue to focus on solving "long-standing issues" in the Zcash ecosystem, including key pain points such as wallet usability and infrastructure stability.

According to Jinshi citing Al Jazeera, Iranian President Pezeshkian announced more details about the US-Iran agreement. The Iranian president stated that as part of a preliminary agreement to end the war with the United States, the $6 billion in frozen funds currently held by Qatar will be returned. All terms of the memorandum of understanding are favorable to Iran, and the results of these negotiations and discussions will gradually become apparent. The Iranian president also mentioned that Trump "previously prohibited us from doing many things, and now he declares that all of this belongs to the rights of the Iranian people and nation."Pezeshkian also mocked Israeli Prime Minister Netanyahu, saying he would "be the first to be dissatisfied with the Swiss negotiations." He further stated that the only demand from the United States is that Iran does not possess atomic bombs. Former Iranian Supreme Leader Khamenei has also repeatedly stated that Iran does not want atomic bombs. The United States requires Iran to commit in writing not to possess nuclear weapons, and Iran signed it.

According to Solid Intel, the payment of approximately $12 billion in frozen assets from Iran may be completed using the Trump-related stablecoin USD1 (the World Liberty Financial stablecoin launched by World Liberty Financial).
