• Developers add BPO EIP-7892 to Fusaka.

• SEC crypto custody roundtable agenda.

• JustaName introduces an ENS wayback machine.

During this week’s ACD Execution Layer call #155, Ethereum core developers agreed to move EIP-7892 to Scheduled for Inclusion (SFI) status for Fusaka, the upgrade planned after Pectra later this year. EIP-7892 introduces Blob-Parameter-Only (BPO) Forks, lightweight hard forks that adjust only two parameters: blob targets and blob limits. BPO forks aim to strike a balance between solo staker bandwidth and Layer 2 data availability demands to support scalable blob transactions. Fusaka’s inclusion list now features PeerDAS, EOF, and BPO. Developers also moved EIP-7917 to Considered for Inclusion (CFI). EIP-7917 proposes a deterministic proposer schedule embedded in the beacon state at the start of each epoch, enabling better predictability for preconfirmation protocols.

The SEC released the agenda for its upcoming crypto custody roundtable, “Know Your Custodian: Key Considerations for Crypto Custody,” taking place on April 25, 2025. The event will explore legal and regulatory issues surrounding crypto custody, with a focus on broker-dealer and investment adviser frameworks. Established in January 2021, the SEC’s Crypto Task Force—led by Commissioner Hester Peirce—seeks to build a clear regulatory framework for crypto assets. Its mission includes setting registration guidelines, encouraging innovation, addressing fraud, and coordinating with domestic and international regulators.

JustaName introduced ENSvolution.xyz, a Wayback Machine for tracking historical updates to ENS domain names. The tool provides a timeline of onchain events such as text record changes, profile updates, resolver changes, and content hash modifications. It leverages ENSNode by Namehash Labs to query Ethereum Name Service (ENS) data without relying on The Graph’s subgraphs. JustaName plans to expand support to include transfers, registrations, and expiry dates.

• EigenLayer activates slashing on mainnet.

• Timeboost goes live on Arbitrum chains.

• Fabric introduces an inbox for based rollups.

• Ethena introduces a modular RWA chain

EigenLayer launched slashing on mainnet, marking the completion of its core protocol launch. Slashing allows Actively Validated Services (AVSs) to enforce accountability by penalizing operators who violate service-level conditions, such as incorrect computation or liveness failures. The upgrade introduces two critical enforcement mechanisms. First, Unique Stake Allocation lets Operators assign specific portions of their stake to individual AVSs, isolating slashing risk and clarifying responsibilities. Second, Operator Sets enable AVSs to group operators with custom slashing rules. Early adopters of EigenLayer slashing include LayerZero and Infura DIN.

Arbitrum launched Timeboost on Arbitrum One and Arbitrum Nova mainnet. Timeboost is a transaction ordering policy that allows users to optionally pay a fee for priority block inclusion while mitigating the impact of MEV. The policy uses an encrypted mempool, ensuring that transaction details remain hidden until the transaction order is finalized. Timeboost auctions currently occur nearly every minute, achieving a 70–90% utilization rate. To participate, users must deposit WETH into the auction contract before submitting bids. The activation aims to reduce network congestion, protect users from MEV attacks and generate new revenue for the Arbitrum DAO. 

Fabric, a collaborative initiative focused on developing standards for rollup infrastructure, introduced Retroactive Attestation of Inbox Data (RAID) — a new inbox design for Ethereum rollups adopting based sequencing. Rollups require an inbox to accept transaction data such as blobs. In based sequencing, Ethereum L1 proposers also serve as rollup sequencers. RAID enables based rollups to use a secure and decentralized inbox model that supports preconfirmations without needing real-time knowledge of the current L1 proposer. With RAID, anyone can submit blobs, which are then filtered. Validation occurs retroactively, and valid blobs are promoted to the safeHead, which rollups use to derive state.

Ethena Labs, in collaboration with Securitize, introduced Converge, a modular Layer 2 network focused on Real World Assets (RWAs). Built on the Arbitrum Orbit stack, Converge leverages Celestia for data availability and uses a custom G2 sequencer developed by Conduit. The network includes the Converge Validator Network (CVN)—a security and coordination layer powered by staked ENA. Converge aims to bridge traditional finance and DeFi by supporting both permissioned RWA applications and permissionless DeFi protocols. Converge is launching on testnet in the coming weeks, with mainnet expected in Q2 2025.

• Soneium introduces a Fast Finality Layer.

• Optimism launches the SuperStacks program.

• Farcaster launches Snapchain on mainnet.

• Safe restructures its team.

Soneium, an Optimism-based Layer 2, introduced a Fast Finality Layer designed to speed up transaction finality on the Layer 2 network. The new consensus layer was developed in collaboration with Astar Network, AltLayer, and EigenLayer to reduce finality delays from Ethereum’s current ~13 minute finality times to under 10 seconds. The Fast Finality Layer uses AltLayer’s MACH service for fast confirmations, an integration with EigenLayer for economic security, and leverages a dual staking model using Astar Network’s ASTR token and restaked ETH to secure the consensus layer. The collaboration extends ASTR’s role in Ethereum's shared security ecosystem.

Optimism launched SuperStacks, a new points-based rewards program offering incentives for users who provide liquidity across Superchain networks, including Base, OP Mainnet, Unichain, Soneium, Ink, and World Chain. The program focuses on interoperable assets, notably USDT0—the first Superchain interop-ready stablecoin, fully backed 1:1 by canonical USDT on Ethereum. Superchain interoperability enables native portability and fungibility of assets across all participating chains, reducing reliance on fragmented bridged tokens and enhancing security. Rewards are distributed based on the amount and duration of liquidity provision. The pilot will run from April 16 to June 30, 2025. Participating protocols include Uniswap, Velodrome, and Stargate.

Farcaster launched Snapchain, a high-performance data layer now live on mainnet. Snapchain delivers 10x cheaper storage, supports throughput exceeding 9,000 transactions per second (TPS), and introduces zero-cost signers, allowing users to add or remove apps for free. Snapchain already powers the Warpcast client, used to read and write data, improving cross-app performance. Built in Rust, Snapchain eliminates friction from micro-fees and enables seamless synchronization across apps. Snapchain combines blockchain reliability with social media user experience expectations.

Safe co-founder Lukas Schor announced that 14 team members are being laid off from Safe as part of a broader organizational restructuring. Going forward, Safe will operate through three teams: a revenue-driven product company, an innovation-focused R&D lab, and an ecosystem foundation dedicated to community and governance. Originally spun out of Gnosis in 2022, Safe secures over $100 billion in assets.
