Ethereum Layer 2 network ZKsync issued a reminder on X platform that during protocol upgrade v26, there is a temporary issue with backward compatibility of the Mailbox contract, which will affect L1→L2 transactions. Because the relevant transactions were initially processed by the Mailbox contract, but during the v26 upgrade, due to the bridging and L2 being in different transitional stages, the backward compatibility is temporarily not working. Currently, resolving this issue may take 1.5-2 weeks, so it is recommended that users use "requestL2TransactionDirect requestL2TransactionTwoBridges" on BridgeHub, instead of Mailbox, and also recommend migrating to BridgeHub to avoid the Mailbox contract being deprecated in the future.

Robbie Mitchnick, BlackRock's head of digital assets, praised the success of the firm's Ether (ETH) exchange-traded fund (ETF) but pointed out a key limitation. Speaking at the Digital Asset Summit on March 20, he highlighted the absence of staking in the current ETF, describing it as "less perfect." Mitchnick emphasized the importance of staking yield in generating investment returns in the crypto space, noting that adding staking to Ether ETFs is a complex challenge that needs to be addressed. Despite the potential benefits, staking ETH comes with risks such as slashing, which could deter traditional investors due to the added layer of risk involved. Joseph Lubin, Ethereum co-founder, also discussed the narrative surrounding Ethereum and emphasized the importance of targeting applications that matter to users and businesses rather than engaging in broad theoretical discussions. BlackRock has promoted Ethereum to investors as a bet on blockchain adoption, innovation, tokenization, stablecoin adoption, and decentralized finance. Data from SoSoValue indicates that ETH ETFs currently hold a total value of $7 billion as of March 20, with a cumulative inflow of $2.5 billion but have experienced a cumulative outflow of $358 million in the past 11 days amid struggles in the cryptocurrency market.
