According to a report on April 29th, some observers believe that Morgan Stanley's entry into the US spot Bitcoin ETF may serve as a catalyst for ending the cryptocurrency bear market, as it has the distribution capability of an $8 trillion wealth advisory network. However, Blockstream CEO Adam Back stated that institutional adoption is slow, and ETF portfolio building may take 1 to 18 months. He mentioned the impact of Bitcoin's four-year halving cycle and believed that the market's strength needs to wait for institutional capital inflows to manifest. In addition, he denies being the founder of Bitcoin, Satoshi Nakamoto, and claims that the institution's risk management on the threat of quantum computing is more systematic.

[Attackers Exploit EIP-7702 Vulnerability to Steal 1,988.5 QNT] According to disclosures by SlowMist, attackers exploited the EIP-7702 vulnerability to steal 1,988.5 QNT (approximately 54.93 ETH) from the QNT reserve pool. The vulnerability originated from the reserve pool administrator's EOA delegating code execution to the BatchExecutor contract, which in turn authorized the BatchCall contract without proper access control. Due to the lack of permission verification in the BatchCall.batch() function, any external caller could invoke it, resulting in the depletion of the reserve pool's assets.
