Etherscan launched a new feature called Cards on its address pages, offering quick access to specialized information, including claimable airdrops, open token approvals, and input data messages. The claimable airdrops card, powered by Bankless, shows the number of unclaimed airdrops and their estimated value. Users are then directed to the Bankless Claimables site to identify the airdrops. Reputable projects within the Ethereum community can add an Etherscan Card to display specific information about an address directly on the Etherscan explorer. Etherscan Cards are available only for EOAs and not for contract addresses.
Caldera, a rollup-as-a-service provider, introduced support for zkSync's ZK Stack, a framework for launching custom zero-knowledge hyperchains. Hyperchains are zkEVM instances that operate in parallel, settle on Ethereum L1, and connect through a shared bridge. The integration marks Caldera’s first supported ZK Rollup framework. The ZK Stack offers two data availability options, including onchain data with ZK Rollup and offchain data with zkPorter, and supports the use of a project's own tokens for sequencer decentralization. In addition to ZK Stack, Caldera already supports the Arbitrum Orbit and OP Stack frameworks for optimistic rollups.
EtherFi, the leading liquid restaking protocol with $3.7 billion in TVL, launched Liquid Market-Neutral, a new managed DeFi strategy vault designed for stablecoin yield generation. The vault accepts deposits in USDC, USDT, DAI, and USDe, which are then deployed across Aave, Curve Finance, Gearbox Protocol, and Pendle.fi. As the vault's deposits increase, EtherFi intends to expand its yield sources to include Uniswap V3, MorphoLabs Blue, and Balancer positions. Market-Neutral is EtherFi's second vault strategy; its first vault focuses on generating yields from ETH and weETH deposits. The vaults automatically rebalance positions to maintain optimal yield.
A U.S. district judge sentenced Binance founder CZ to four months in prison. The sentence comes from a case initiated by the U.S. Department of Justice, which accused CZ of failing to comply with the Bank Secrecy Act and Know Your Customer (KYC) requirements. Although the DOJ initially sought a three-year sentence, the final decision was considerably less severe. Previously, CZ had used the number 4 to convey a message of ignoring fear, uncertainty, and doubt.

EigenLayer introduced EIGEN, its protocol token coined as the Universal Intersubjective Work Token. The total supply of EIGEN is 1.67 billion tokens, with 55% allocated for investors and early contributors, while the remaining 45% is allocated for the community. Of the community's share, 5% is allocated for an initial stakedrop. Restakers on EigenLayer can check their eligibility for the first stakedrop at claims.eigenfoundation.org. The stakedrop is based on a snapshot taken on March 15th. Claiming will go live on May 10th; however, the tokens will initially be non-transferable. Users who have restaked on EigenLayer using complex LRT integrations will need to wait until a later date to claim their tokens Transferability of EIGEN tokens is planned to be enabled after the community has a solid understanding of the new protocol design, once payment and slashing mechanisms go live, and once the community stakedrops are completed. Users will also have the ability to stake their EIGEN tokens.
EigenLayer published a whitepaper introducing its Universal Intersubjective Work Token, a new protocol design that provides social consensus as a service. The system allows for token forking in instances where a majority of stakeholders engage in malicious behavior. It addresses intersubjective faults, which are issues that require subjective consensus among observers. While ETH staking targets objective faults with specific use cases, EIGEN staking is designed for more universal applications, addressing intersubjective faults. The protocol incorporates a dual-token system to mitigate risks linked to forking, including a metering system to assess the costs of switching tokens and a compensation mechanism to safeguard users from losses. The framework is currently open to community input.
Recent court documents reveal that the SEC began probing Ethereum's classification as a security in March 2023. The investigation commenced before a house committee meeting where SEC Chair Gary Gensler was unable to classify Ethereum as either a security or a commodity. The SEC authorized its enforcement staff to issue subpoenas and conduct inquiries into individuals. In 2023, Consensys received three subpoenas demanding detailed information on its Ethereum transactions, acquisitions, and its role in the Ethereum Improvement Proposals relating to the Merge. Consensys complied with the requests, producing an extensive 88,000-page report. Despite cooperating, the SEC escalated its scrutiny by issuing a Wells notice to Consensys.
Ethereum has reached a milestone of 1 million active validators securing the network, the highest number since the Beacon Chain was launched. Currently, 32 million ETH are staked, representing 26% of the total supply of Ethereum, valued at just over $100 billion. The increased amount has led to a reduction in the staking APY to approximately 3.5%.

Offchain Labs disclosed two security vulnerabilities in Optimism’s fraud-proof system on the OP Sepolia testnet. The flaws were reported to OP Labs on March 22nd. The vulnerabilities could have enabled a malicious actor to either validate a fraudulent claim or invalidate a genuine one within the fraud-proof system. The issues were related to management of time credits in the fraud-proof system, which could have been accumulated by dishonest parties. OP Labs implemented a fix on April 25 via an update deployed on the OP Sepolia testnet. OP Labs is concluding a security audit contest before it proposes deploying the fraud-proof system on mainnet.
ApeCoin selected Caldera's rollup-as-a-service platform to launch ApeChain, a gaming-centric Arbitrum Orbit L3 chain. ApeChain will leverage Caldera's infrastructure and integrated services to manage its L3 chain and enable ApeCoin as the native gas token. Caldera’s toolkit includes a bridge interface, a block explorer, and on/off ramps. In the coming months, ApeChain will roll out several testnets, enabling early gaming partners to begin integrations. The first testnet for ApeChain will operate under chain ID 1798. The partnership comes as Yuga Labs CEO Greg Solano announced a company-wide restructuring, which includes layoffs.
A Dune Analytics dashboard shared by Tom Wan reveals that over 15% of Ethereum staked on the Beacon chain is now restaked through EigenLayer. The amount totals to 4.9 million ETH, valued at approximately $15.42 billion. Out of this, 3.1 million ETH is restaked natively, predominantly through liquid restaking protocols. 1.7 million ETH is restaked via liquid staking tokens, with Lido’s stETH accounting for 1 million stETH of deposits. Of Ethereum's total supply of 122 million ETH, about 26% is staked on the Beacon chain. EigenLayer first began accepting deposits into its protocol in June 2023.
Renzo Protocol, the second-largest LRT protocol by TVL, announced the details for its second points season, following the conclusion of the first season today. Users will be able to claim their REZ tokens from season one starting April 30th at 11:00 UTC. The upcoming Season 2 will allocate an additional 5% of the token's supply to users who earn ezPoints over the next three months. Participants from Season 1 will receive a 10% boost in their Season 2 earnings.
