The Arbitrum Security Council executed an emergency upgrade to freeze 30,766 ETH from an address involved in the KelpDAO exploit, moving $71 million into a frozen intermediary wallet. The council briefly modified the inbox contract on L1 to include a function enabling cross-chain messages that could impersonate any sender, used it once to transfer the funds, then restored the contract. The Arbitrum DAO will decide the next steps. Read more →
Base announced the Azul upgrade, its first standalone network upgrade. It introduces multiproofs and brings Base closer to Stage 2 decentralization. The upgrade also consolidates operations onto base-reth-node and a new base-consensus client built on Kona. Azul is now live on testnet with mainnet activation set for May 13, 2026. Base is also hosting a $250,000 audit competition through May 4. Read more →
The Coinbase Quantum Advisory Council released its first position paper examining quantum computing's impact on cryptocurrency. The report concludes that current cryptographic systems remain secure today, but advances in quantum computing could compromise crypto security within the next decade. Specifically, current wallet-level signature schemes are significantly more vulnerable. Read more →
Optimism introduced Privacy Boost, a plug-and-play SDK for adding confidentiality to any OP Stack chain. The release aims to help projects meet regulatory requirements such as MiCA, BSA, AML/KYC, and GDPR. Privacy Boost combines zero-knowledge proofs with trusted execution environments on a UTXO-based model, generating proofs in under 500 milliseconds, and features a forced withdrawal option. Privacy Boost is now live on OP Mainnet. Read more →

Coinbase Publishes Quantum Readiness Paper
The Coinbase Quantum Advisory Council, with researchers from the Ethereum Foundation, Eigen Labs, and Stanford, warns crypto security could be compromised within the next decade.
The Coinbase Quantum Advisory Council, an independent group of researchers from the Ethereum Foundation, Eigen Labs, and Stanford, released its first position paper examining the potential impact of quantum computing on cryptocurrency. The report concludes that while current cryptographic systems remain secure today, advances in quantum computing could compromise crypto security within the next decade.
It highlights that the immutability of transaction history is largely resistant to quantum threats. However, wallet-level signature schemes are significantly more vulnerable. The paper notes the challenge of transitioning millions of existing wallets to quantum-resistant signature schemes.

Base Introduces Multiproofs With Azul Upgrade
Base's first standalone upgrade since leaving the Superchain introduces multiproofs combining TEE and ZK, plus a new client stack built on OP Kona.
Base announced the Azul upgrade, its first standalone network upgrade since departing Optimism's Superchain. The upgrade introduces multiproofs, enhancing security, decentralization, performance, and the overall developer experience. By combining Trusted Execution Environments (TEE) with zero-knowledge (ZK) proving, multiproofs move Base closer to Stage 2 decentralization.
Azul also streamlines the network architecture by consolidating operations onto a single execution client, base-reth-node, alongside a new consensus client, base-consensus, built on OP Kona. The upgrade is already running on testnet, with mainnet activation set for May 13, 2026. Node operators will need to transition to the new client stack ahead of that date.
Base is currently hosting a $250,000 audit competition on Immunefi running through May 4. Looking ahead, the team plans to introduce an enshrined token standard and Flashblock access lists by the end of June, followed by native account abstraction by the end of August.
