• Privacy Pools live on Ethereum mainnet.

• Superseed deploys its L2 on mainnet.

• Chainlink launches Payment Abstraction.

• Circle introduces USDCKit.

Privacy Pools, an onchain privacy protocol, is now live on Ethereum mainnet. Users can now deposit between 0.1 and 1 ETH. The protocol requires all deposits to pass a wallet screening process before they become eligible for private withdrawal. If a deposit fails the screening, users can still withdraw their funds back to the original wallet. Privacy Pools use zero-knowledge proofs and ensures that deposit and withdrawal addresses are unlinked. Privacy Pools supports configurable privacy sets, allowing users to preserve privacy while preventing association with known malicious addresses. The release is currently in a beta phase.

Superseed, a DeFi-focused Layer 2 built on the OP Stack, is now live on mainnet. Users can now interact with core infrastructure and use DeFi applications on the network, including Velodrome, SeedFi, Orange Finance, Bebop, Ionic, and Dolomite. In the coming weeks, Superseed plans to launch its Seeds rewards program. Superseed introduces SuperCDP, a native collateralized debt position system designed to offer interest-free, self-repaying loans using assets like ETH, WBTC, and the Superseed token as collateral to mint and borrow the Superseed stablecoin. The system will be powered by protocol revenue streams such as sequencer profits.

Chainlink launched Payment Abstraction on Ethereum mainnet, a new cross-chain system that allows users to pay for Chainlink services using ETH or alternative tokens. The payments are automatically converted into LINK using a combination of Chainlink Automation, Price Feeds, CCIP, and Uniswap V3. The feature aims to reduce payment friction for Chainlink Network users. Payment Abstraction is also implemented into to Chainlink SVR, an Oracle MEV recapture solution recently integrated with Aave. Payment Abstraction will allows Chainlink Decentralized Oracle Network (DON) node operators to consolidate LINK rewards on Ethereum, with initial support for CCIP node operators.

Circle introduced USDCKit, a new SDK designed to streamline USDC payment integration and automation for developers. It offers tools for automating wallet creation, payouts, settlements, compliance, and cross-chain transfers. Now available in early access, USDCKit will expand support for swaps and on/off ramps.

• Vitalik outlines L2 security roadmap.

• FDIC updates crypto activity guidelines.

• ENS introduces Multi Delegation Manger.

Vitalik Buterin published a forum post outlining a roadmap to improve the security, finality, and scalability of Ethereum L2 rollups. To meet L2 data availability demands, he proposes continuing blob space increases, targeting 72 blobs by the Fusaka upgrade. For rollups progressing to Stage 2 decentralization, he proposes a pragmatic fast finality approach using a 2-of-3 hybrid proof system involving optimistic, ZK, and TEE-based provers. Finally, he emphasizes the need for standardized proof aggregation layers—shared infrastructure that bundles ZK proofs from various applications into a single submission to Ethereum. Standardized aggregation layers would significantly reduce gas costs and improve scalability across the ecosystem.

Aave has integrated Chainlink Smart Value Recapture (SVR) into its V3 Ethereum mainnet market. Chainlink SVR is a specialized oracle solution that enables DeFi protocols to reclaim non-toxic Maximal Extractable Value (MEV) generated through Chainlink Price Feeds. The integration allows Aave to recapture liquidation-related MEV that was previously extracted by block builders. Developed in collaboration with BGD Labs, Flashbots, and other Aave DAO contributors, Chainlink SVR leverages Chainlink Price Feeds and Flashbots’ MEV-Share to redirect value back to DeFi protocols. As outlined in a recently approved Aave DAO proposal, SVR-generated revenue will be split: 65% allocated to Aave and 35% to Chainlink for the initial six months. Aave is now the largest protocol on Etheruem by TVL.

The FDIC has rescinded its 2022 Notification of Engaging in Crypto-Related Activities guidance (FIL-16-2022), which required FDIC-supervised banks to notify the agency before engaging in crypto-related activities. In its place, the FDIC has issued new guidance (FIL-7-2025) that permits banks to engage in allowable crypto-related activities without needing prior approval. Under the new guidance, banks may now offer services such as crypto-asset custody, stablecoin reserve management, digital asset issuance, and market making or exchange operations. The FDIC stated it will continue working with other regulatory agencies and the President’s Working Group on Digital Assets.

• Pectra is scheduled for April 30th.

• Tether Superchain interop-ready USDT0.

• ENS integrates Para sign-in.

• Mass launches tokenized stocks on Base.

Ethereum core developers have tentatively scheduled the Pectra hard fork to go live on Ethereum mainnet for Wednesday, April 30, 2025, at slot 11,599,872. Client teams plan to release updated client versions by April 14th. Once released, node operators must update their client software before the mainnet activation. The Pectra upgrade introduces 11 EIPs, including Account Abstraction EIP-7702, max effective balance EIP-7251, execution layer-triggerable withdrawals EIP-7002, and EIP-6110, which removes the delay between validator deposits and processing. Pectra will also increase Ethereum's blob capacity by 50%. 

Tether launched USDT0 as a Superchain interop-ready stablecoin on OP Mainnet. USDT0 is an omnichain version of USDT, fully backed 1:1 by canonical USDT on Ethereum. Users can redeem USDT0 for USDT on Ethereum from any supported chain. It marks the first stablecoin deployed with native Superchain interop. Superchain interop enables seamless portability and fungibility of assets across all Superchain chains, eliminating the need for fragmented bridged versions and enhancing overall security. As an interoperable Superchain asset, USDT0 will benefit from features like 1-block finality, zero slippage, and unified security. USDT0 is currently live on OP Mainnet and Ink.

ENS integrated sign-in with Para on the ENS Domains web app, enabling users without an existing wallet to easily register and manage ENS domains. Users can now log in to the portal using their email, phone number, or social media accounts via Para, a wallet and authentication tooling provider. Para uses passkeys to create portable embedded wallets that are accessible across devices using web2-friendly login methods like Discord and Google accounts. The integration aims to lower the barrier to entry for new users to onboard to the ENS ecosystem.

Mass, a DeFi and RWA protocol, launched support for tokenized stocks on Base. The implementation uses Dinari to issue dShares, which are 1:1-backed tokens representing real stock shares, ETFs, or bonds held in custody. Once tokenized, the assets are delivered to the user’s Mass account, enabling them to trade, hold, and receive dividends directly. Dividends are paid in USD+, a stablecoin backed by short-term U.S. Treasuries and redeemable for USDC.
