Taiko launched its Based ZK-Rollup on Ethereum mainnet, enabling users to bridge assets and interact with over 10 initial dapps currently live on the network. The genesis block of Taiko was proposed by Vitalik Buterin, featuring a special quote in the block’s metadata. Taiko is built on a Based Contestable Rollup (BCR) architecture, which features a versatile multi-proof system. Based rollups leverage Ethereum block builders for sequencing transactions. Currently, Taiko supports SGX proofs, with plans to support Risc0-zkVM and SP1 zkVM proof systems in the future. In the coming weeks, Taiko will open up its network for permissionless block proposing and proving. Users can currently participate in Taiko’s trailblazer program as part of its second airdrop wave.

Aerodrome, a version of the Velodrome DEX deployed on Base, has outperformed Uniswap V3 in 24-hour trading volume on Base. Over the past day, Aerodrome saw over $200 million in trading volume, surpassing Uniswap V3's $152 million. With a TVL of $728 million, Aerodrome holds more than double the TVL of Uniswap's Base deployment. Aerodrome is part of the Velodrome Superchain, a MetaDEX serving as the liquidity and trading hub for OP Stack chains. Both Uniswap and Aerodrome deployed on Base when the network first went live in August 2023.

Scroll, an EVM-Equivalent ZK-Rollup, integrated economy deposits into its native bridge. The new feature allows users to opt-in for a batched deposit when bridging from Ethereum to Scroll Mainnet. Rather than executing deposits immediately, the system batches multiple deposit requests for up to an hour and then processes them all in a single transaction. The batched transfer saves users up to 50% on gas fees compared to bridging individually. Fast deposits are still available, with deposit times of up to 20 minutes.

The TVL across all Ethereum L2 networks reached a new record of $48 billion, more than doubling in the past five months. Arbitrum One remains the top rollup by TVL with $19.3 billion worth of assets. Optimism and Base lead in second and third place with TVLs of $7.9 billion and $6.9 billion, respectively. Linea, an EVM-equivalent ZK rollup by Consensys, has become the leading ZK-rollup by TVL, outpacing zkSync and Starknet.

Ethereum core developers are targeting to launch Pectra, the next upgrade for Ethereum, by the end of the first quarter of 2025. The inclusion of EVM Object Format (EOF), which is a set of about 11 EIPs that introduce an opt-in container for EVM code, is a key component that is pushing the upgrade timeline to 2025. The upgrade is set to feature PeerDAS, a data availability sampling solution that uses existing peer-to-peer components within Ethereum. Developers also agreed to replace the account abstraction EIP-3074 with a newer proposal, EIP-7702, introduced by Vitalik. EIP-7702, enables EOAs to function as smart contract wallets during a transaction. Pectra consists of the Prague upgrade on the Execution Layer and the Electra upgrade on the Consensus Layer.  The final scope of the upgrade is still under discussion, with potential changes like postponing Verkle to the Osaka hardfork.

EtherFi launched its waitlist for EtherFi Cash, the third component of its suite, designed to enable users to spend and borrow against their EtherFi balances. Cash consists of a mobile wallet linked to a Visa credit card, allowing users to either borrow USDC against their EtherFi assets or convert them directly into USDC. EtherFi rewards can also be used to settle outstanding balances. EtherFi Cash aims to eliminate the need to offramp crypto for daily transactions. The Visa cards are expected to be shipped in September. EtherFi also has plans for a Layer 2 solution to enhance payment processing and dispute resolution for Cash. Currently, EtherFi is the largest liquid restaking protocol, managing over $5.5 billion in TVL.

Polymarket resolved its prediction market for the approval of an Ethereum ETF by May 31st. The resolution followed controversy stemming from the SEC's approval of multiple 19b-4 filings for Spot ETH ETFs, while the necessary Form S-1 filings required for trading remain unapproved. Some users argued that an ETF isn't fully approved until both filings are approved. UMA Protocol, an Optimistic Oracle provider, ultimately determined a "Yes" outcome based on the 19b-4 filings that were approved. Bloomberg analyst James Seyffart noted that a 19b-4 approval historically leads to S-1 approvals. The prediction market had a total of $13.2 million in bets.

Arbitrum has achieved over one billion total transactions between Arbitrum One and Arbitrum Nova. Over the past month, Arbitrum One has topped the charts in daily active addresses, recording over 3.6 million active addresses in just the last 24 hours. As the leading Layer 2 network, Arbitrum One holds $18.5 billion in TVL, capturing a 40% market share among all rollups.

The U.S. Securities and Exchange Commission (SEC) has granted approval for eight Spot Ethereum ETFs managed by asset managers Grayscale, Bitwise, BlackRock, VanEck, ARK Invest and 21Shares, Invesco, Fidelity, and Franklin Templeton. The ETFs will be listed for trading on NYSE Arca, Nasdaq, and Cboe BZX Exchange. However, trading will not commence immediately, as the SEC still needs to approve the S-1 forms submitted by the asset managers, a process that could take weeks to months. A spot Ethereum ETF mirrors the market price of Ethereum, offering investors a way to gain exposure to Ethereum without the need to directly hold ETH. The price of ETH has be volatile throughout the day, hitting a new monthly high of $3,937.

Optimism opened applications for its fourth retroactive funding round, coined Onchain Builders. The round will allocate 10 million OP tokens to builders who have deployed contracts on OP Stack chains, including as Base, Mode, Redstone, and Zora. The submission window is open until June 6th at 19:00 UTC, but those who apply by May 31 will receive a commemorative NFT. To qualify, the smart contracts must have interacted with a minimum of 420 unique addresses between January 1 and May 1, 2024, sustained contract activity for at least 10 days, and have verified contract ownership on GitHub. Badgeholders will vote on submissions next month, with winners to be announced on July 15th.

WalletConnect unveiled AppKit and WalletKit, its latest development kits for connecting wallets to dapps. AppKit enables developers to incorporate features such as email and social logins, onboarding with Safe-powered smart contract wallets, fiat-to-crypto onramps, and swapping functionality into their apps. WalletKit simplifies the process for developers to integrate "Connect with WalletConnect", which enables users to connect to desktop applications from their mobile wallets. WalletKit also includes one-click connections and verifications. Both kits support notifications triggered by onchain actions. The new development kits are scheduled for release on June 12th.

Safe launched an ERC-7579 Adapter, enabling the integration of modules from external platforms into Safe smart accounts. The ERC-7579 standard establishes interfaces for modules that ensure interoperability across different wallet implementations. The ERC-7579 adapter enhances wallet functionality, supporting modules such as Passkeys and Session Keys. Developers can now implement the adapter on existing Safe accounts.
