ZK Cross-Chain Latest Here we report on the progress of the leading builders in the ZK Cross-Chain ecosystem, documenting recent significant releases, technical breakthroughs and general updates. Featuring: @AcrossProtocol, @Agglayer, @EspressoSys, @hyperbridge, @PolyhedraZK, & @union_build. 🔹 Visit for more reports from across the industry 🔹

Across 🔹 Publications 🔹 @AcrossProtocol published two new articles that explore the rapid evolution of stablecoin infrastructure and how interoperability layers are becoming essential in a multichain financial world: 1. The first article breaks down the stablecoin bridge problem, showing how stablecoins dominate global onchain activity yet remain fragmented across chains, and explains how intent-based routing and native burn-and-mint networks are converging into a unified experience that Across coordinates with fast, cheap, and secure transfers: 2. The second article examines the rise of stablechains like @Plasma, @arc, and @tempo, describing how each network is purpose-built for stablecoin payments and showing why seamless interoperability between them is critical - ultimately highlighting Across as the unifying layer that keeps stablecoin liquidity fluid across all chains: Additionally, @kanishkkhurana wrote a piece highlighting how x402 is gaining attention as a payment-gated API standard enabling onchain micropayments across websites and services: 🔹 Visit for more reports from across the industry 🔹

Agglayer (@0xPolygon) 🔹 Identity 🔹 @Agglayer is working with @billions_ntwk to provide a portable, privacy-preserving identity layer for Web3: Billions, a mobile-first ZK verification network for humans and AI agents, has already verified more than 2 million users. Built on the open-source @PrivadoID stack, it lets people prove uniqueness without sharing personal data. Integrated with Agglayer, these credentials can move across chains, reducing fragmentation, limiting Sybil attacks, and supporting trusted AI activity, with added incentives through the Agglayer Breakout Program. 🔹 Publications 🔹 Agglayer shared an article covering how CDK Enterprise helps private blockchains reduce rising costs, simplify operations, and avoid isolation from broader ecosystems: The platform keeps data private while posting public proofs, supports standard identity systems, and includes governance controls that match existing security practices. It also offers three migration paths suited to different risk levels. When organizations choose, they can connect their chain to Agglayer for access to users, liquidity, and partners without rebuilding infrastructure. 🔹 Visit for more reports from across the industry 🔹

Hyperbridge @hyperbridge has restarted DOT bridging after @Polkadot shifted key functions to the Asset Hub on Nov 4: The migration streamlines Polkadot’s structure, easing congestion and lowering fees while improving support for stablecoins and cross-chain assets. Hyperbridge users should see faster and cheaper transfers. 🔹 Visit for more reports from across the industry 🔹

Polyhedra @PolyhedraZK reported continued progress on Expander, noting improvements in FPGA acceleration: Highlights: • Engineers finalized the GF2-128 arithmetic pipeline, achieving stable 277 MHz operation on FPGA. • End-to-end testing for the Keccak-based circuit reached roughly 75,000 to 77,000 proofs per second. • The team said overall speed is limited by the Network-on-Chip bandwidth of about 250 MHz. • Work has begun on using soft NoC resources to ease congestion and support higher sustained frequencies. 🔹 Visit for more reports from across the industry 🔹
