HashKey Cloud Joins Stacks Genesis Bond Pilot to Test Institutional Demand for Native Bitcoin Yield

Stacks announced that HashKey Cloud will participate in the network’s Genesis Bond pilot, becoming the second institution to lock Bitcoin in the new native‑yield protocol.

How the Genesis Bond Works

Participants place Bitcoin in a time‑locked output on Bitcoin’s base layer and retain the private keys. The BTC remains outside any lending, wrapper, or third‑party custody arrangement and is immobile for the bond’s term unless the early‑exit option is used. Early exit returns the principal but ends any remaining yield, while the paired STX remains locked for the full period.

STX Requirement and Risk Exposure

The bond requires a collateral of STX equal to roughly 5 % of the Bitcoin amount. This STX determines the participant’s Bitcoin capacity and subjects the position to STX price movements for about six months. Yield is generated from Stacks miners who commit BTC to produce blocks and receive STX block rewards. Returns are targeted at about 3 % annualized but can vary with miner economics, fees, and network activity.

Pilot Structure and Future Plans

The first bond operates within a managed bootstrap set by the Stacks Endowment during the PoX‑5 phase. Parameters such as capacity, target yield, BTC‑to‑STX ratio, and allocation are defined centrally. A future PoX‑6 upgrade aims to replace these managed settings with an algorithmic, permission‑less auction.

Security and Known Issues

The Stacks codebase has been audited by Trail of Bits and the Clarity Alliance, with additional review by Asymmetric Research. An open medium‑severity issue in the bond rollover path could affect reward distribution for participants moving between bonds, though it does not impact the core custody model.

Implications for Institutional Interest

HashKey Cloud’s involvement signals institutional curiosity about a yield product that keeps Bitcoin under self‑custody while exposing participants to STX market risk and miner‑funded payouts. The size of HashKey’s allocation and the bond’s eventual payouts will provide concrete data on institutional demand.
