HashKey Cloud has joined Stacks as a launch partner for self-custodial Bitcoin staking. This collaboration will enable users to earn rewards on their BTC without transferring it to a centralized custodian.

As part of the Genesis Bond, HashKey Cloud will participate in the inaugural bond and join the signer network securing sBTC. The company operates under HashKey Holding Limited and manages over HK$29 billion in staked assets across more than 40 blockchain networks.

The Genesis Bond is a new feature that allows institutions to earn BTC-denominated rewards without transferring their Bitcoin to a centralized custodian. This system uses Proof of Transfer (PoX), where miners commit BTC while competing to produce blocks, and the protocol distributes part of that Bitcoin as rewards.
