October 7, 2026 — HashKey Cloud, the Web3 infrastructure service provider under HashKey Group (HK.3887) — a leading global digital asset financial services group — announced a technical partnership with Bitcoin collateral infrastructure company Babylon Labs to integrate its Trustless Bitcoin Vaults (TBV), providing node operation, validation, and infrastructure support for the TBV network.

In the past, if Bitcoin holders wanted to use native Bitcoin in on-chain applications, they typically needed to wrap or bridge their assets. Through the integration of TBV, native Bitcoin can now be used as a technical component in on-chain applications without wrapping, bridging, or intermediaries. This not only connects the Bitcoin ecosystem with the Ethereum network, but also further enriches HashKey Cloud's technical service capabilities at the institutional infrastructure layer.

Fisher Yu, Co-Founder of Babylon Labs, stated: “This partnership enables HashKey Cloud to play a node and validation support role within the TBV infrastructure, helping to enhance network robustness and institutional-grade infrastructure capabilities. The trustless, self-custodial design of TBV provides a technical pathway for exploring on-chain Bitcoin applications.”

Leo Li, CEO of HashKey OnChain, stated: “This is more than just a technical integration; it is a major step forward in connecting the Bitcoin ecosystem with institutional-grade infrastructure. We are thrilled to partner with Babylon to provide node and infrastructure support for the TBV network, empowering clients to access the native Bitcoin ecosystem more efficiently.”

For HashKey Cloud, this integration also signifies further technical connectivity with various custodians, wallets, and licensed exchanges, while deepening ecosystem collaboration with Babylon Labs to deliver more robust technical support for clients.
