>Union: ZK-Driven Interoperability Protocol

Union is a cross-chain interoperability protocol based on zero-knowledge proofs, breaking the traditional cross-chain bridge model that relies on multi-signatures or centralized oracles. Its core architecture includes: CometBLS consensus mechanism (lowering verification costs and supporting large-scale validators through BLS aggregate signatures and MiMCcC-galoris zero-knowledge proof system (generating consensus proofs in 7 seconds, with low barriers and runnable on personal devices), and the Voyager relay system (featuring automatic recovery, parallel processing, and anti-front-running), forming a trustless, efficient, and stable cross-chain infrastructure.

In early December last year, Union Union announced Union announced the12 million Series A funding round, led by Umi LongHash Ventures, with participation from Borderless Capital, Blockchange, ATOM Accelerator, Eterna Capital, Veris Ventures, LBank Labs, Gate Ventures, TRGC, bringing its total funding to $16 million.

Additionally, Union has been listed on Kaito's Pre-TGE Community Leaderboard.

Interaction Tutorial

Currently, the Union Foundation has been established, and the V2 version of the final stage mainnet testing activity is now online, making it worth "zero-effort" interaction.

STEP 1. Strong obtain Holesky and Sepolia testtokens (retrieval link: https://cloud.google.com/application/web3/faucet).

>2ETH on Holesky and Sepolia tesolia test networks to WETH (conversion links: https://sepolia.etherscan.io/token/0x7b79995e5f793a07bc00c210050ecae098e7f9#writeContract, https://holesky.etherscan.io/address/0x94373a4919B3240D86e41593D5 D5 a789FE3848#write3#writeContract).

<3. Connect MetaMask and Keplr wallets to perform cross-chain operations directly on supported networks (link: https://app.union.build/transfer).
