Agglayer (@0xPolygon) 🔹 Tech 🔹 @Agglayer has launched AggKit, a standardized toolkit that enables non-CDK blockchains to connect to its interoperability network: Part of the Agglayer v0.3.5 release, AggKit introduces two core tools - AggSender and AggOracle - for safely reading and writing global state across chains. The update also strengthens bridge security, with expanded integration features planned for early 2026. 🔹 Partnerships 🔹 @forknet_io, developed by @NeurochainAI, has launched its mainnet as a CDK OP Stack L2 on Agglayer: The platform introduces a native crosschain orderbook that unifies liquidity across connected chains, allowing seamless spot and perpetual trading. Built for developers and market makers, Forknet offers EVM compatibility, efficient execution, and revenue generation through Vault Bridge, aiming to simplify and strengthen crosschain DeFi infrastructure. 🔹 Bug Bounty 🔹 Agglayer has launched a public bug bounty for its cross-chain Vault Bridge on @cantinaxyz: Security researchers are invited to review live smart contracts that generate sustainable yield from bridge deposits. Rewards of up to $1 million are offered, depending on the severity of discovered vulnerabilities. 🔹 Visit for more reports from across the industry 🔹

Espresso @EspressoSys has announced new integrations that expand its role as a base layer providing fast finality and crosschain composability, including: • @BuildOnNodeOps: Integrated Espresso to enhance coordination across its decentralized cloud computing marketplace. The integration brings fast finality, improved security against sequencer equivocation, and enables other systems to read NodeOps’ state in near real-time - critical for streamlined infrastructure deployment and payments: • Rufus: The @arbitrum Orbit L2 behind @DogelonMars’s metaverse integrated Espresso to support real-time transaction finality and secure crosschain composability. This allows Rufus to maintain fast sequencer speeds while gaining decentralized finality, supporting features like bridgeless NFT minting and seamless asset movement between chains: 🔹 Visit for more reports from across the industry 🔹

Hyperbridge 🔹 Integrations 🔹 @hyperbridge has integrated @0xPolygon’s mainnet into its cross-chain network after a successful testnet phase, extending verifiable interoperability across Web3: Operating as a cryptoeconomic co-processor on @Polkadot, Hyperbridge now connects Polygon with multiple major blockchains, enabling secure, trustless token transfers and messaging. The integration strengthens Polkadot’s role as a multichain hub and expands Hyperbridge’s interoperability footprint. 🔹 Token2049 🔹 At the @token2049 hackathon in Singapore, MicroPay, built on Hyperbridge technology, won a category prize for its system enabling cross-chain micropayments between AI agents: Using Hyperbridge, a Polkadot-based interoperability coprocessor, MicroPay allows secure and efficient transactions across 14 blockchains. The project highlights progress toward autonomous, machine-driven economies where AI systems can pay for services directly, reducing friction and improving cross-chain communication. 🔹 Visit for more reports from across the industry 🔹

Orbiter Finance @Orbiter_Finance has announced new integrations, expanding its cross-chain bridging capabilities across emerging networks: • @SuperseedXYZ: Integrated support for bridging ETH and USDC to Superseed - an L2 built on the Superchain, focused on innovative on-chain debt repayment models: • @XLayerOfficial: Enabled bridging of ETH, USDT, and USDC to X Layer through the Orbiter Finance interface: 🔹 Visit for more reports from across the industry 🔹

zkLink @zkLink_Official has announced two new partnerships: • @WORLD3_AI: Integrated with zkLink’s aggregated rollup to enable AI agents to autonomously route liquidity, trade across chains, and operate within ZK-enforced guardrails - paving the way for scalable, cross-chain AI economies: • @revoxdotai: Partnered with zkLink to combine AI trading agents with its L3 zkEVM aggregation, unlocking intelligent, autonomous DeFi trading across ecosystems with improved speed and performance: 🔹 Visit for more reports from across the industry 🔹
