Ethereum developers, alongside the ethPandaOps team, successfully restored finality on the Holesky testnet at Epoch 119090, which occurred around 18:56 UTC on March 10th. The achievement comes after nearly two weeks of non-finalization caused by a configuration bug during the Pectra hard fork on Holesky. More than two-thirds of the validator stake on the testnet has attested to the correct state. Finality is typically reached every two epochs, approximately every 12.8 minutes. Affected nodes on Holesky should clear their datadir and sync from the last finalized state. A state backup is available at holesky-rescue.ethpandaops.io.

Ethereum developer Marius Van Der Wijden outlined an edge case attack on Sepolia’s deposit contract following the recent Pectra upgrade on the testnet. An issue with Sepolia’s deposit contract led to empty blocks. Developers temporarily replaced problematic transactions with higher-paying ones while preparing to ship a coordinated fix. However, they discovered that the issue causing the empty blocks persisted due to an attacker exploiting an edge case, allowing the attacker to send 0-token transfers to the deposit contract, which triggered the issue. To address the attacker, developers privately deployed a fix to a few nodes to avoid alerting the attacker before the official coordinated update was rolled out.

Coinbase announced plans to launch perpetual-style futures for U.S. users, offering 24/7 markets for Bitcoin and Ether perps trading. The platform will likely support USDC as collateral. Perpetual futures are contracts without an expiration date, allowing traders to hold positions indefinitely as long as they maintain margin. The perpetual futures platform is still under development and is being designed to comply with U.S. regulatory standards with guidance from the CFTC. Coinbase aims to provide a competitive alternative to existing offshore futures platforms.

BackedFi, a tokenized real-world asset issuer, introduced wbCOIN, a tokenized representation of Coinbase’s COIN stock, now available on Base. Fully backed 1:1 by COIN stock, wbCOIN provides a legal claim to the value of COIN stock while remaining freely transferable. Users can access it on CoW Swap, with liquidity provided via Aerodrome. The token is not issued nor affiliated with Coinbase. BackedFi currently holds over $20 million in TVL in tokenized RWAs.

MegaETH, an EVM-compatible L2, is now live on testnet for developers. The current release phase focuses on onboarding infrastructure and apps, with a public rollout expected next week. The launch includes experimental support for EIP-7702, which enables smart account functionality for EOAs. MegaETH also features 10ms mini-blocks and 1s EVM blocks. Mini-blocks are lightweight, high-frequency blocks produced alongside traditional EVM blocks, offering the same security guarantees with rollback protection. Unlike Base’s Flashblocks, they do not rely on TEEs. MegaETH also features elastic block production, meaning blocks are only created when transactions exist. MegaETH aims to achieve 100,000 TPS throughput performance.

Worldcoin, a digital identity protocol, launched World Chat, a mini app that enables users on the World Network to send end-to-end encrypted messages. By linking their World App wallet, users can also send and receive crypto seamlessly within chats. World Chat leverages World ID’s Proof of Personhood to verify human authenticity. Developers can integrate World Chat into their Mini Apps to enhance user engagement and interactions. Built on the OP Stack, World Chain is a Layer 2 network designed for identity-centric applications on World Network.

Safe, the smart contract wallet provider breached in the recent ByBit hack, released an update on its investigation. Findings reveal that the attackers compromised a Safe developer's laptop and exploited AWS session tokens to bypass MFA controls, gaining unauthorized access to Safe{Wallet} infrastructure. The attack was carried out over 19 days. Safe’s Smart Contracts remain unaffected. In response, the Safe team has performed an infrastructure reset, restricted external access, enhanced monitoring, and improved malicious transaction detection. The Safe team urges the community to adopt stronger security measures and advocates for improved transaction verification tools.

The Mekong testnet, a short-lived testnet designed for wallet developers and stakers to test UX changes introduced in the Pectra upgrade, will be deprecated on March 7, 2025. With Pectra now activated on the Sepolia and Holesky testnets, developers are encouraged to use Sepolia for application and smart contract testing due to its stable validator set. Stakers and infrastructure providers should wait for Holesky to finalize or check the Ethereum R&D Discord for updates.

The Pectra upgrade was successfully activated on the Sepolia testnet on March 5th at 7:29 UTC. While now stable, the testnet initially faced an issue due to Sepolia’s permissioned deposit contract, which prevented execution layer (EL) clients from properly including transactions, leading to mostly empty blocks. The issue was identified immediately and addressed by client teams. Sepolia has since restored normal network throughput. Node operators are urged to update their execution layer clients to the latest version. Similar to Holesky, the issue was specific to Sepolia’s non-standard, deposit contract and cannot occur on Ethereum mainnet.

The Aave Chan Initiative (ACI) published a temp check proposal to introduce sGHO, a low-risk savings product for GHO that will offer users the Aave Savings Rate (ASR). By staking GHO, users will receive sGHO, a yield-bearing token that accrues interest over time at the Aave Savings Rate, which will be influenced by market conditions. sGHO aims to compete against other savings products like Sky’s sUSDS. The yield for sGHO will be generated through GHO borrowing, facilitator liquidity deposits, and other mechanisms. sGHO will feature no rehypothecation, ensuring that deposited GHO won’t be used to generate additional yield, which offers a low-risk investment.

Devconnect, the Ethereum-focused developer conference, announced that Buenos Aires, Argentina, will host Devconnect 2025 from November 17th to 22nd, 2025. The event will kick off with an opening ceremony on November 17th, followed by a six-day "Ethereum World's Fair" and coworking sessions. Devconnect Argentina will emphasize localization, supporting the country’s growing adoption of Ethereum.
