AggLayer has launched its unified bridge, marking a significant shift in multi-chain architecture. Instead of multiple bridge contracts on Ethereum for different L2s, AggLayer introduces a single bridge contract for all connected chains. Key features: - Single bridge contract on Ethereum manages all chain connections - Local bridge root copies enable direct cross-chain transactions - Eliminates need for L2 → L1 → L2 bridging - Currently connects 2 chains, with more planned for 2024 The unified bridge is the first component of AggLayer's vision for an aggregated blockchain environment, aiming to enable near-instant, secure cross-chain transactions and unified liquidity.

Agglayer has introduced CDK OP Stack configuration, offering developers a new way to build OP Stack chains with enhanced features: - Zero-knowledge (ZK) technology integration for improved security - No Superchain tax or seven-day delays - Native Agglayer interoperability - Performance: 60-100+ Mgas/s (~4,700+ peak TPS) Two implementation options available: - cdk-opgeth by @conduitxyz: ZK-powered OP Stack - cdk-erigon by @gateway_eth: 90% reduced storage, custom gas tokens Future updates will include SP1 zkVM execution proofs with Polygon Plonky3 for faster finality.

Polygon has confirmed support for Ethereum's upcoming Pectra upgrade featuring EIP-7702, marking a significant advancement in wallet functionality. Key updates: - EOAs (Externally Owned Accounts) will gain smart account features - Enhanced user experience for onchain payments - Improved support for Real World Assets (RWA) The upgrade is already implemented in Agglayer via CDK, with rollups built on CDK OP Stack offering immediate support. Additional stack support is expected soon. *Technical Impact*: This upgrade represents a substantial improvement to Ethereum's infrastructure, particularly in wallet functionality and payment processing.

Polygon's Q1 2025 metrics show significant growth in stablecoin activity. Key highlights: - Total stablecoin supply increased 23% - Active stablecoin wallets up 30% - Individual stablecoin growth: * USDC: 31% * USDT: 13% * DAI: 47% Broader ecosystem metrics: - Daily active wallets: 550K - Daily transactions: 3.4M - Positive growth in DeFi, bridges, and NFT activity Full details available in [Messari's State of Polygon Q1 2025 Report](https://messari.io/report/state-of-polygon-q1-2025)

Polygon Labs and Irreducible have unveiled PetraVM, an open-source zkVM designed to enhance performance and reduce proving costs through binary field towers technology. Key developments: - Built to achieve faster performance than existing ZK methods - Aims to enable secure interoperability on Agglayer - Developed by research team led by @RobinSalen, @_bfarmer, and @dlubarov This follows Polygon's recent launch of Plonky3, a modular toolkit for building customized zkVMs. The project adds to Polygon's growing ZK portfolio, which includes: - Type 1 ZK-EVM prover - Agglayer CDK - Pessimistic Proofs - Plonky2/3 proving systems [View PetraVM documentation](https://github.com/PetraProver/PetraVM)
