What is Union?​

Union is a zero-knowledge (ZK) infrastructure layer designed to enhance interoperability across blockchain ecosystems. The project aims to solve one of the most critical challenges in the blockchain industry: connecting different networks that operate in isolation. Union enables seamless general message passing, asset transfers, NFT bridging, and DeFi interoperability between various blockchains and rollups without relying on third-party intermediaries.

At its core, Union addresses blockchain fragmentation by providing subsecond messaging protocol and chain abstraction capabilities. This infrastructure allows developers and users to experience a more unified blockchain ecosystem, where assets and data can move efficiently between networks. By leveraging zero-knowledge technology, Union offers a privacy-preserving, scalable solution that significantly improves cross-chain interactions while maintaining security and efficiency.

Union Airdrop Detials​

Currently, Union has not officially confirmed an airdrop, but community speculation suggests that participants in Testnet 9 (described as the final testing phase before mainnet launch) may be eligible for a future token distribution. Union Labs, the entity behind the project, has raised $16 million in funding, including a $12 million Series A round led by Gumi Cryptos Capital and LongHash Ventures announced in December 2024.

Testnet 9, the final version of the Union testnet, is now live. This is your last opportunity to test the network before the mainnet launch. While the airdrop remains speculative, completing tasks on the testnet and participating in on-chain missions may position users for potential rewards when Union launches its mainnet and native token.
