Union is a hyper-efficient zero-knowledge interoperability layer engineered for seamless message passing, asset transfers, NFTs, and DeFi. Built to support EVMs, SVMs, altVMs, and more, Union delivers subsecond intent-driven communication across diverse execution environments using innovations like CometBLS consensus, Galois zk-provers, and the decentralized Voyager relayers.
Union has officially launched its mainnet, introducing a new standard for trustless cross-chain interoperability. Designed for message passing, asset transfers, NFTs, and DeFi, Union enables seamless connectivity across EVMs, SVMs, altVMs, and more. Its architecture combines zero-knowledge cryptography, CometBLS consensus, the Galois prover, and Voyager relayers to deliver sub-second communication and secure execution without trusted intermediaries.
LayerHub Joins as an Early Validator
We’re proud to announce that LayerHub is part of the very first validator set on Union. For us, this is more than just securing a network – it’s about backing a project that pushes the boundaries of what’s possible in web3.
Throughout the testnet, we stood alongside dozens of validators, maintaining stability and security during breaking transfers volumes. To now be securing Union at mainnet launch is both an honor and a responsibility we take seriously.
Driving Adoption: LayerHub’s Role in Union’s Journey
From the very beginning of the Union Testnet, LayerHub has been actively supporting Union with analytics, tools. Our goal has always been to make user activity transparent, measurable, and engaging.
Here’s what we’ve achieved together so far:
- Wallet Checker – a tool to track wallet ranking, activity days, transfers, and contract interactions.
- Comprehensive analytics since day one of the testnet, helping users and developers understand engagement patterns and optimize activity.
The results speak for themselves:
- 80,000+ wallet checks
- 35,000+ unique users leveraged LayerHub tools during the testnet.
Looking Back: Key Testnet Metrics and Milestones
The Union Testnet demonstrated the network’s efficiency and scalability with strong cross-chain activity:
Total number of transfers and wallets by number of transfers
Over 272 million transfers have been processed to date, with daily peaks reaching 94 million. Notably, 79% of wallets executed more than 25 transfers, showing that engagement went far beyond one-off activity and highlighting Union’s role as a reliable layer for sustained cross-chain usage.
Wallets by Active Days and New Wallets on Union
More than 650,000 wallets joined, and remarkably, 34% of them stayed active for over 20 days.
Ecosystem Overview
The network is already supported by a wide range of projects that bring liquidity, interoperability, and developer tools into the ecosystem. Each new integration not only expands functionality but also deepens community engagement and adoption.

What’s Next: Our Plans Moving Forward
Mainnet launch is only the beginning. What’s next?
- Union mainnet dashboard on LayerHub, delivering real-time analytics and insights.
- Validator and relayer expansion, with advanced monitoring and optimization tools.
- Ecosystem growth across DeFi, NFTs, and cross-chain applications, powered by Union’s zero-knowledge messaging layer.
- Deeper integrations with infrastructure providers, wallets, and enterprise partners to drive adoption at scale.
We believe Union is laying the foundation for the next era of seamless, trustless interoperability – and we at LayerHub are proud to support that journey from the very start.
