. @union_build was born to fix one of crypto’s biggest gaps: secure, trustless cross-chain interoperability.

Here’s why they’re a serious contender:

• $4M seed (Nov 2023) – backed by Nascent, Semantic, Galileo, Chorus One
• $12M Series A (Dec 2024) – led by Gumi Cryptos & LongHash
• X testnets shipped – each upgrade = better UX, stronger security, deeper multichain support
• Live across major chains: Babylon, Arbitrum, Stargaze, Secret, Ethereum & more
• Largest Groth16 ZK setup ever – XXXXX contributors to trusted setup

What’s next:
→ Cross-chain staking from day one (Cosmos + Ethereum)
→ Governance-ready token built for real DeFi composability
→ Mainnet coming fast — we’re likely in the final phase

Union is one of the cleanest, most battle-tested plays in the interoperability race.
