Use Cases & Benefits
- Implements a trust-minimized, zero-knowledge bridging protocol for secure, censorship-resistant message passing and asset transfers across blockchain ecosystems.
- Eliminates reliance on trusted third parties, oracles, multi-signatures, or MPC by using consensus verification and zero-knowledge proofs for high security and decentralization.
- Use for enabling interoperable DeFi applications that require secure cross-chain asset transfers between Cosmos and EVM-compatible chains.
- Use for building censorship-resistant NFT bridges that maintain privacy and integrity across multiple blockchain networks.
- Use for deploying modular, upgradable smart contracts with decentralized governance controlling protocol evolution and token configurations.

From the README
Union is the hyper-efficient zero-knowledge infrastructure layer for general message passing, asset transfers, NFTs, and DeFi. Its based on Consensus Verification and has no dependencies on trusted third parties, oracles, multi-signatures or MPC. It implements IBC for compatibility with Cosmos chains and connects to EVM chains like Ethereum, Berachain (beacon-kit), Arbitrum, and more.
The upgradability of contracts on other chains, connections, token configurations, and evolution of the protocol will all be controlled by decentralized governance, aligning the priorities of Union with its users, validators, and operators.
Install Nix to reproducibly build any component, and to enter a dev shell with all dependencies:
(Note that some components can only be built on Linux. If you are using macOS, we recommend using OrbStack to easily set up a NixOS VM within two minutes. Most Union developers use macOS with OrbStack, and there is no need to install Nix inside of the NixOS VM.)
You can now reproducibly build any of Union's components from source:
