Union network is a hyper-efficient zero-knowledge infrastructure layer for general message passing, asset transfers, NFTs, and DeFi. It’s based on consensus verification and has no dependencies on trusted third parties, oracles, multi-signatures, or MPC. Union uses advanced Zero-Knowledge Cryptography and BLS signatures to bring the fastest and most secure inter-blockchain communication protocol, IBC, everywhere.

Union has raised $4M in funding from investors such as Nascent and Semantic Ventures and has launched a testnet. Join the testnet by claiming testnet UNO tokens and transferring assets between chains. Users who interact with testnet will likely get an airdrop when their tokens goes live.

Step-by-Step Guide:
  1. Visit the Union testnet page.
  2. Connect your Metamask and a Cosmos wallet like Keplr.
  3. Now click on “Faucet”, submit your Union address and claim testnet UNO tokens. You can obtain your Union address by accessing the connected wallet section located in the top right corner.
  4. Now go to “Transfer” and transfer UNO from Union testnet to Sepolia testnet.
  5. Also, transfer assets from Ethereum Sepolia to Union testnet.
  6. You will need some testnet ETH on Sepolia to be able to transfer from Sepolia. You can get some from here.
