In accordance with the Ethereum testnet lifecycle, the Goerli testnet will be deprecated by April 17th. Ethereum core developers had previously agreed to deactivate Goerli testnet validators either three months after the Dencun activation on Goerli or one month after Dencun activates on mainnet. Given that Dencun was activated on Goerli on January 17th, the three-month mark is on April 17th. Developers currently using the Goerli testnet are advised to transition their applications to Sepolia or Holesky testnets before Goerli's deprecation on April 17th. A new Ethereum testnet is rolled out every two years, with a maximum lifespan of five years for each testnet. Optimism will decommission the OP Goerli testnet on March 7th.  The Goerli testnet was initially deployed in 2019.

Gitcoin unveiled its whitepaper for Gitcoin 2.0, the next iteration of its protocol that introduces new capital allocation mechanisms and extends support to more EVM-based chains. Gitcoin 2.0 shifts operations onchain, including governance, grant creation, management, and fund disbursement. It also introduces Direct Grants and Retro PGF as funding mechanisms Gitcoin 2.0 takes a modular approach to capital allocation, powered by the Grants Stack. The framework empowers communities to design custom mechanisms for fund distribution within their ecosystems. The whitepaper for Gitcoin 2.0 is now open for community feedback, prior to being ratified by Gitcoin Governance.

Gnosis Chain reached 200,000 validators on its PoS network, making the second-largest chain in terms of validator count, second only to Ethereum. Gnosis Chain, previously known as xDAI, is an EVM-compatible sidechain that uses DAI as its native gas token. xDAI was acquired by the Gnosis ecosystem in 2021. The sidechain shares the same architecture as Ethereum and is committed to Ethereum's values of decentralization, neutrality, and diversity. Gnosis Chain makes home-based validation more accessible by only requiring a single GNO token to become a network validator.

Lens Protocol achieved 200k minted profiles on its open social-graph network. The accomplishment follows a surge of over 60,000 new profiles since the protocol went permissionless earlier this week. The permissionless launch enables anyone to mint a Lens Profile for 8 MATIC. Profile NFTs are built on the ERC-6551 standard, enabling content to be owned by the Profile NFT. Lens Protocol has been live on Polygon since February 2022.

Robinhood announced that its non-custodial wallet is set to integrate swaps on the Arbitrum One network. The move aims to provide low-cost and high-speed transaction capabilities to over 2 million Robinhood Wallet users. The wallet currently supports assets across Ethereum, Bitcoin, Dogecoin, Arbitrum, Polygon, Optimism, and Base. While the activation is not live, it is anticipated to roll out in the coming months. Robinhood is a leading stock, ETF, options, and cryptocurrency trading service provider. Arbitrum One, developed by Offchain Labs, stands as the leading optimistic rollup L2 network, boasting the highest TVL of more than $13 billion.

Coinbase introduced smart wallet support within the Coinbase Wallet SDK, enabling developers to seamlessly integrate instant wallet creation into their dapps requiring only a passkey. The solution eliminates the need for seed phrases and allows users to use their assets across any dapp integrated with the Coinbase Wallet SDK. The feature is live on the Base Sepolia testnet. Coinbase Wallet as a Service (WaaS) allows developers to design embedded wallets with web2 login methods such as email or social login. Coinbase is providing gas credits through Coinbase Cloud to developers who are building smart wallet integrations and infrastructure.

Blast, an EVM-compatible optimistic rollup offering native yield, has officially launched on mainnet. The milestone unlocks assets worth $2.3 billion, previously deposited by early adopters farming for Blast Points. Users can now add the Blast Mainnet RPC to their wallets to migrate their deposited assets to the L2 network. Blast also announced new incentives for users who bridge to Blast Mainnet and engage with dapps on the rollup. However, the Blast Points airdrop cannot be claimed until the TGE event in Q2 of this year. Applications now live on Blast Mainnet include Bebop, Zora, Relay, Rhino.fi, ZeroLend and Ambient Finance.

Starknet introduced Stwo, an open-source prover implementing the Circle STARK protocol.  Stwo improves proof performance, making it more efficient and versatile, and will be compatible with the Cairo code of Sierra. The advancement allows for the use of a highly efficient prime field called M31, which was previously incompatible due to mathematical constraints. The end result is faster and cheaper transactions for users and improved scalability for applications. Starknet is Starkware’s permissionless ZK-Rollup-based L2.

OpenZeppelin released its Defender 2.0 security platform for general availability, allowing developers to integrate security tools, smart contract operations, and automate actions directly within their applications. Defender safeguards deployed contracts against known risk parameters. Defender features a Code Inspector, an automated tool that identifies and flags vulnerabilities. Code Inspector automatically generates comprehensive reports for each pull request, providing users with a detailed rundown of potential issues. The Defender Deploy API supports deterministic contract deployments across chains. Defender supports over 40 chains and customizable EVM network configurations. Users on the Defender 1.0 release are required to migrate to 2.0, as 1.0 will be deprecated by June.

Coinbase encountered degraded performance on its exchange amid a market rally. Earlier today, Bitcoin surged past $63,000, while Ethereum reached $3,500. The overall crypto market cap saw an increase from $2.3 trillion to $2.45 trillion. Coinbase users reported witnessing a zero balance on their accounts during the outage. Performance was restored on Coinbase approximately three hours after the surge. CEO Brian Armstrong stated that the team had prepared a traffic surge of about ten times the usual volume, but the recent influx of users surpassed that projection. Currently, the market has stabilized, with Ethereum trading around $3,340 at press time.

Coinbase Cloud announced support for Nethermind and Erigon execution clients into its Ethereum staking infrastructure. The move follows a commitment regarding plans to diversify its clients beyond Geth. Coinbase aims to achieve an even distribution of execution client software across Geth, Nethermind, and Erigon. The activation of Nethermind clients by Coinbase is scheduled to be rolled out this week. Ethereum's multi-client philosophy serves to safeguard against the risks associated with reliance on a single client. Data from clientdiversity.org indicates that Geth dominates as the supermajority client with over 70% market share.

The Ethereum Ecosystem Support Program (ESP) launched the 4844 Data Challenge, inviting data enthusiasts to dive into the analysis and interpretation of insights from EIP-4844 data on Ethereum. The competition aims to gather submissions documenting the most compelling 4844 data insights in an easy-to-read blog post. Participants have until June 14, 2024, to submit their entries for an opportunity to win a share of a $30,000 prize pool. EIP-4844 is scheduled to activate on Ethereum mainnet on March 13th.
