The cross-chain liquidity protocol Maya Protocol was attacked on August 18, with the attacker exploiting six interconnected software vulnerabilities to create false account balances, stealing approximately 20.83 BTC (about $1.34 million) and other assets, resulting in a total direct loss of about $1.65 million. The incident led to the suspension of trading on the MAYAChain network, with its token CACAO plummeting nearly 89% from $0.115 to $0.013, before recovering to around $0.03.Technical reviews show that the attack began when MAYAChain mistakenly judged a transaction to be lost and triggered a compensation mechanism, but the mechanism miscalculated, adding about 49 million CACAO to a small liquidity pool, while the protocol's reserves only held about 168,000 CACAO. After the transfer failed, the system incorrectly saved the new balance, and the attacker subsequently deposited a very small amount into the liquidity pool, acquiring over 99% of the pool's share and immediately withdrawing 48.87 million CACAO, which was then exchanged for Bitcoin, Ethereum, and other assets.The incident caused the total value of the Maya Protocol liquidity pool to decrease by about $10.9 million, of which approximately $6.4 million was due to the depreciation of CACAO, and about $2.9 million came from arbitrage trading. The team expressed hope that the attacker would return the funds in the form of a bug bounty; otherwise, they would seek to recover losses through investments in channels like Aztec Chain. Maya Protocol has not yet announced a specific time for resuming trading. This incident once again exposed the security risks within the complex logic of DeFi protocols.

China has begun to relax import restrictions on NVIDIA's H200. ByteDance and Tencent have each received about 10,000 H200 in recent weeks, and several other tech companies may soon be approved for similar quantities.The United States had previously approved several Chinese companies to purchase H200, but the transactions had been stuck in the Chinese approval process. Now, chips are finally starting to enter the mainland in batches, but it is far from a complete opening.Beijing currently only allows a small number of H200 to enter the mainland, hoping that companies will deploy more chips in overseas regions such as Hong Kong. Mainland procurement still requires separate approval. This approach allows leading AI companies to continue using NVIDIA to train cutting-edge models while also leaving market space for domestic chips like those from Huawei.
