Echo Base là một tổ chức chuyên về tài sản kỹ thuật số ổn định, hỗ trợ thành lập Ủy ban chủ nợ BitMart, đại diện cho người dùng nắm giữ tài sản bị đóng băng, và thuê cố vấn pháp lý đánh giá các phương án thu hồi, bao gồm việc xin thủ tục phá sản không có sự hỗ trợ tài chính. Echo Base đã đề xuất một kế hoạch tài chính tối đa 10 triệu USD, dự kiến hỗ trợ BitMart nộp đơn xin phá sản đã được thương thảo trước, nhưng không nhận được phản hồi từ BitMart.Echo Base cho biết, các hành động liên quan xuất phát từ việc BitMart không phản hồi đề xuất tái cấu trúc và yêu cầu rút tiền của người dùng. Sonn Law Group đã tiến hành điều tra đối với những người dùng có tài sản bị đóng băng tại BitMart từ 500.000 USD trở lên, đánh giá các yêu cầu bồi thường tiềm năng và phương án thu hồi tài sản. CEO của Echo Base, Roshan Dharia, cho biết, kế hoạch của nhân viên BitMart chỉ có thể duy trì hoạt động đến tháng 1 năm 2027, thời gian trì hoãn càng lâu, phương án khả thi càng ít.

Echo Protocol announced that its eBTC deployment on Monad experienced unauthorized activity, resulting in abnormal minting and financial losses. Preliminary investigations indicate that the issue stemmed from the compromise of the administrator keys related to the Monad deployment, with approximately $816,000 in assets currently confirmed to be affected.Echo stated that the Monad network itself was not affected and continues to operate normally. The team has regained control of the administrator keys and has destroyed the remaining 955 eBTC held by the attacker. The project further clarified: the current incident appears to be limited to the Monad deployment; there is no evidence to suggest that the Aptos side has been affected; aBTC on Aptos and eBTC on Monad are independent, non-bridgeable assets; the current related risk exposure on Aptos is approximately $71,000.As an additional precaution, Echo has suspended the cross-chain functionality of the Monad deployment and has begun upgrading the related EVM bridging contracts and permission control mechanisms, while reminding users not to interact with any unofficial claims, refund, or recovery pages.

Keone Hon, co-founder of Monad, posted on the X platform that the Monad network is unaffected and operating normally, while security researchers are investigating the eBTC-related incident of the Echo Protocol. Researchers have determined that the vulnerability led to approximately $816,000 being stolen. Previously, it was reported that the Echo Protocol was attacked on the Monad chain, where hackers minted 1,000 eBTC and withdrew funds via Curvance.

Echo Protocol announced that it is investigating a security incident affecting the Echo cross-chain bridge on Monad. During the investigation, all cross-chain transactions remain suspended.According to previous reports, market news indicated that Echo Protocol was hacked on Monad. The attacker minted 1,000 eBTC (approximately $76.7 million) and used a tested process to deposit 45 eBTC (approximately $34.5 million) into Curvance. Subsequently, they borrowed approximately 11.29 WBTC (approximately $867,700) using this as collateral, bridged the WBTC to Ethereum, exchanged it for ETH, and ultimately transferred 384 ETH (approximately $821,700) to Tornado Cash.Yuxian, the founder of Slow Mist, stated that Echo Protocol may have been compromised due to the Admin single point private key being breached.

According to Onchain Lens monitoring, Echo Protocol was attacked on the Monad chain. The attacker minted 1,000 eBTC ($76.7 million) and withdrew funds from Curvance through a previously tested attack path.Currently, the attacker has deposited 45 eBTC ($34.5 million) into Curvance as collateral, borrowed about 11.29 WBTC ($867,700), and cross-chained to Ethereum, sending 385 ETH (approximately $818,000) to TornadoCash after exchanging for ETH. The attacker still controls a large amount of minted eBTC.

The distributed AI lab Gradient today released the Echo-2 distributed reinforcement learning framework, aimed at breaking the barriers of training efficiency in AI research. By achieving a complete decoupling of Learner and Actor at the architectural level, Echo-2 has reduced the post-training cost of a 30B model from $4,500 to $425. This results in over 10 times the research throughput under the same budget.The framework utilizes compute-storage separation technology for asynchronous training (Async RL), offloading massive sampling computation to unstable GPU instances and Parallax-based heterogeneous GPUs. Coupled with breakthroughs in bounded staleness, instance fault-tolerant scheduling, and the self-developed Lattica communication protocol, it significantly enhances training efficiency while ensuring model accuracy. Along with the framework release, Gradient will soon launch the RLaaS platform Logits, promoting the shift in AI research from a "capital accumulation" paradigm to an "efficiency iteration" paradigm. Logits is now open for reservations for students and researchers worldwide.

According to GMGN monitoring, Cobie, the founder of Echo XYZ, tweeted about "Copper Inu" today on platform X, leading to the emergence of several meme coins named "COPPERINU" on the Solana chain. The token with the highest market cap quickly surged to $12 million and has now retraced to about $9 million, with a price of approximately $0.009.In the tweet, Cobie stated, "You don't have to worry about waking up one day to find Copper Inu has taken all of copper's market share. They won't pop up like some digital assets do, with new products emerging every few seconds to disrupt existing value."Additionally, GMGN monitoring indicates that the address ranked first in holdings (A1EC...) belongs to Equation founder himgajria's publicly disclosed on-chain address. This address invested about $10,000 when COPPERINU's market cap was only around $80,000, and it currently has an unrealized profit exceeding 10,000%. Although some has been sold, the total profit still reaches approximately $740,000.

According to Onchain Lens monitoring, AAVE founder Stani Kulechov spent 1,699 ETH (approximately 5.15 million USD) to purchase 32,660 AAVE tokens at an average price of 157.78 USD. Currently, Kulechov holds 84,033 AAVE tokens, with a total value of about 12.6 million USD, facing an unrealized loss of approximately 2.29 million USD.
