Funding Obtained: Union Labs Granted $12 Million in Series A Investment for Unifying Cosmos, Ethereum, and Bitcoin Networks
Union Labs Raises $16 Million for Cross-Chain Interoperability
Union Labs, a web3 company, has successfully raised $16 million in a Series A round, co-led by Gumi Cryptos Capital and Longhash Ventures. The funds will be used to expand core teams, advance partner integrations, and accelerate ecosystem growth.
The company's focus is on developing a modular, zero-knowledge powered cross-chain interoperability layer between Ethereum and the Cosmos ecosystem. Union Labs also plans to expand its product offering to include Solana, Berachain, Celestia, Avalanche, and more.
One of the key objectives is to link the cross-interoperability layer to Bitcoin, aiming to make asset transfers more secure across Bitcoin L2s and the multichain ecosystem. However, as of August 2025, no specific timeline for the mainnet launch of Union Labs' cross-chain interoperability layer involving Ethereum, Cosmos, Bitcoin, Solana, Berachain, Celestia, and Avalanche has been publicly detailed.
Industry players such as Chainlink are actively advancing cross-chain interoperability standards and infrastructure, but Union Labs' specific multichain project launch is not mentioned with a concrete launch date. To stay updated on the mainnet launch timeline for Union Labs' cross-chain product, it is recommended to monitor the company's official communications or developer channels.
Union Labs' X platform was mentioned in the announcement, but no new comments from Karel Kubat or other team members were provided. The company has already integrated Polygon's AggLayer and Cosmos' Inter-Blockchain Communication (IBC) protocol.
The fundraising round reflects the team's ongoing dedication to reducing fragmentation by bringing secure, sovereign, and seamless interoperability to Web3, according to Karel Kubat, the founder of Union Labs. Despite the lack of a concrete mainnet launch timeline, the team's commitment to advancing cross-chain interoperability remains strong.
- The funds raised by Union Labs, a web3 company, will be utilized to advance technology in cross-chain interoperability, specifically focusing on linking Ethereum, Cosmos, Solana, Berachain, Celestia, Avalanche, and Bitcoin, thus creating news in the finance and investing sector.
- As Union Labs works towards reducing fragmentation in web3 by introducing secure and seamless interoperability, they plan to incorporate more technologies like Solana, Berachain, and Celestia into their product offerings, following the successful integration of Polygon's AggLayer and Cosmos' Inter-Blockchain Communication (IBC) protocol.
