Stacks Brings Bitcoin Staking to Market With "Genesis Bond"

Bitcoin staking has gone live on the Stacks network through its new "Genesis Bond" program, marking the first time BTC can earn native BTC yield without leaving Bitcoin's Layer 1. Four institutions—21Shares, HashKey Cloud, UTXO Management (a subsidiary of Nakamoto Inc.) and Sypher Capital—participated in the inaugural institutional bonding window, committing a combined 250 BTC. The first weekly reward distribution is scheduled for September 17. Three participants—21Shares, HashKey Cloud and UTXO Management—bonded BTC under self-custody, retaining control of funds throughout the process. Sypher Capital joined via liquid staking through StackingDAO, which bonds STX on an investor's behalf and pairs it with BTC, giving institutions exposure without directly managing the bonding workflow. Yield is generated through Stacks' Proof of Transfer (PoX) mechanism, live since January 2021. In PoX, miners compete to produce blocks by transferring BTC; those BTC flows are paid out to bonders. Since launch, PoX has distributed more than 4,200 BTC—worth over $500 million—to participants. Stacks said the Genesis Bond draws from the same reward stream and is structured to avoid common staking risks: there is no counterparty custodying user funds and no slashing. The stated worst-case outcome is earning no rewards, rather than losing principal. Fireblocks, which secures more than $5 trillion in annual digital-asset transfers, expanded its integration with Stacks to enable institutional clients to access Bitcoin Staking using existing custody and compliance tooling. The Genesis Bond represents the first leg of a three-part Stacks roadmap. The second focuses on scaling via performance improvements and core protocol upgrades. The third targets a Bitcoin-native financial layer, including loans, yield vaults and products designed to deploy bonded capital. According to Stacks Labs, the PoX5 hard fork that established the technical foundation for the system was executed on July 30, 2026 at Bitcoin block 960,230. Registration for the second bonding period, slated for early October, is now open with limited capacity, and several institutions are already enrolled.
