What is Union.Build?
Union.Build is a next-generation blockchain protocol designed to make different blockchains work together seamlessly. Built on the Cosmos SDK, it avoids the usual risks tied to traditional bridges by using light clients and zero-knowledge proofs instead of multisigs or third-party oracles. That means cross-chain messages and transfers can be verified securely on-chain, without needing to trust anyone.
To power this, Union uses a custom consensus engine called CometBLS, which aggregates validator signatures using BLS cryptography. This helps keep zero-knowledge proofs compact and efficient, allowing the system to operate at high speed without sacrificing security.
Union already supports major ecosystems like Ethereum, Arbitrum, Cosmos Hub, and even Bitcoin layers. It also introduces new features like intents, where users can submit a transaction goal, and solvers fulfill it almost instantly.
A DAO also governs the entire network, and the UNION token plays a central role in staking, paying fees, and voting on decisions.
UNION Tokenomics, Distribution, and Burning
UNION Token Purpose and Utility
The UNION token is the backbone of the Union.Build. It is used for staking, transaction fees, and governance.
While the tokenomics have not been officially finalized, the team has shared several confirmed details.
Union will launch the token as an ERC-20 on Ethereum, making it easy for users to access and interact with using familiar wallets like MetaMask.
UNION Token Key Functions
- – Staking: Validators use UNION to secure the network. Token holders can delegate to earn rewards.
- – Governance: Holders can vote on network upgrades, fee changes, and funding decisions.
- – Cross-Chain Support: Thanks to Union’s “cross-chain governance,” users can hold UNION on Ethereum while still participating in staking and voting on the Union chain.
UNION Token Distribution and Supply
Initial allocations will cover:
- – Early investors (Seed + Series A = $16M raised)
- – Founding team
- – Community and ecosystem incentives
Although there is no confirmed burning mechanism, validator slashing helps protect the network.
Union.Build dApp Core Applications and Ecosystem dApps

UNION Token Risks & Considerations
Potential concerns include:
- – Technical complexity: Union relies on zero-knowledge proofs and custom validator logic. If bugs appear in those systems, they could be difficult to catch or patch quickly
- – Strong competition: Established projects like Wormhole and LayerZero already hold significant market share and liquidity
- – Price volatility: As with any new token, UNION/USDT may experience sharp fluctuations after launch, especially in early trading
- – Regulatory uncertainty: Interoperability protocols could come under regulatory scrutiny as global policies evolve
Union has already taken steps to reduce risk. Its trustless architecture avoids custodial bridges, and the trusted setup ceremony brought in thousands of contributors to boost transparency. Still, long-term success will depend on adoption, security, and how quickly the ecosystem grows.
