Stacks Bitcoin Staking lets a holder lock BTC on the Bitcoin chain itself, pair it with STX, and earn a return paid in bitcoin, targeted at about 3% a year at launch. The bitcoin never moves to another chain or custodian: it sits in a timelocked output that only its owner can spend once the roughly six-month term ends. The product went live with the PoX-5 hard fork on Stacks in July 2026, and its first two bonding periods attracted about 735 BTC.
That makes it one of the few ways to earn yield on bitcoin without wrapping it, lending it or handing it to a third party. Below is how a bond works, where the yield comes from, how ordinary holders can take part, and the risks that remain.
How a Protocol Bond Works
Stacks calls each staking position a protocol bond. It follows a fixed lifecycle from registration to maturity:
- Registration opens. Each bond accepts registrations during the two reward cycles before it starts. You commit the full amount up front, since top-ups are not allowed.
- BTC is timelocked on Bitcoin. The bitcoin goes into up to ten lock outputs on the Bitcoin chain that unlock at a set block height. You keep the keys.
- STX is locked on Stacks. The bond requires STX worth at least 5% of the BTC position, locked for the same term.
- The bond runs for 12 cycles. That is 25,200 Bitcoin blocks, about six months. A new bond starts roughly every month, so up to six run at once.
- Rewards accrue weekly. Yield is credited in sBTC at most every 1,050 Bitcoin blocks and can be withdrawn to native BTC if your signer-manager supports a payout address.
- The timelock expires. The BTC lock ends about a week before the bond term closes, and the bitcoin returns to your control. Rolling into the next bond needs a new transaction.
An early exit is possible during most of the term, but it stops rewards from that point, needs a co-signature from a dedicated early-exit signer, and leaves the STX locked until the original end date. The protocol bond FAQ covers the edge cases, including what happens if a registration fails.
Where the 3% Comes From
The yield is paid out of real miner spending. Stacks miners send bitcoin to compete for each block, and under Proof of Transfer that BTC is distributed to stakers. PoX-5 put bonded positions at the front of the queue: they receive the target return first, any surplus goes mostly to holders staking STX alone, and 15% of that surplus builds a reserve to cover bonds when miner revenue runs short.
This structure explains both the appeal and the ceiling. The yield is funded by bitcoin, so it does not depend on printing a reward token, which has been the weak point of many Bitcoin layer-2 yield schemes. But the total pool of BTC is limited by what miners will spend, which depends on the value of the STX they win. To support higher miner bids, SIP-045 restored the block reward to 1,000 STX, a trade-off explained in our STX tokenomics breakdown.
Rollout So Far
Stacks phased the launch carefully. The community approved SIP-045 with more than 99.99% support in July 2026, and the PoX-5 hard fork activated on July 30. The Genesis Bond opened on September 10 with 230 BTC from institutional participants including 21Shares, HashKey Cloud, UTXO Management and Sypher Capital, filling its available capacity.
The second bonding period, which opened in early October, drew about 505 BTC. Around 483 BTC of that came through Stacking DAO's stBTC, a sign that pooled access, rather than direct institutional bonds, may drive the next stage of growth. The Bitcoin Staking rollout page tracks the phases, which run from today's managed bootstrap toward a fully permissionless design planned for PoX-6. Launch capacity is set at 3,000 BTC for the first tranche.
How Individual Holders Can Take Part
Direct native-BTC bonds currently require an allowlist entry, which the Stacks Endowment has allocated mainly to institutions and pool operators. Holders without one have two routes, both of which use sBTC instead of native bitcoin. That means converting BTC through the bridge first, a process described in our sBTC explainer.
Stacking DAO's stBTC is the most popular option. You deposit sBTC, Stacking DAO supplies the required STX from its own reserve, and the value of stBTC rises against sBTC as rewards accrue. You can redeem after a cooldown, or immediately from idle reserves for a fee (1% at the time of writing), and use stBTC in other Stacks apps meanwhile. The model is the same one behind liquid staking tokens on other networks.
Smaller pools such as Esbee DAO take both sBTC and STX from members and split rewards by share. According to the sBTC pool FAQ, Esbee DAO's contracts were unaudited when it was written, while Stacking DAO cites an audit, which is worth weighing before depositing.
Holders who only own STX can still earn from the same miner revenue by staking it alone, following our guide on how to stake STX.
The Risks That Remain
Native-BTC bonds remove custodial risk but introduce others:
- Lock-up risk. Your BTC is unavailable for about six months, and your STX stays locked for the full term even after an early exit.
- STX price risk. The paired STX can fall in value while the bond runs, which can outweigh a 3% BTC return.
- Yield risk. The 3% is a target. Weak miner spending would draw on the reserve, and a long shortfall would reduce payouts.
- Software risk. The timelock scripts, signer software and, for pooled routes, sBTC and pool contracts are all young.
Anyone choosing between holding STX and bonding BTC should also look at the STX price ranges in our STX price prediction, since the paired STX is the volatile half of every bond.
Bitcoin Staking FAQ
Can I stake Bitcoin on Stacks without wrapping it?
Yes, through a native-BTC protocol bond, where your bitcoin stays in a timelocked output on the Bitcoin chain. Direct bonds currently need an allowlist entry, so most individuals use sBTC pools instead.
How much STX do I need for Bitcoin Staking?
You need STX worth at least 5% of your BTC position, locked for the same six-month term. Some pools, such as Stacking DAO's stBTC, provide the STX for you.
What APY does Stacks Bitcoin Staking pay?
The launch target is about 3% a year, paid in BTC. It is a target funded by miner spending, so actual payouts can vary.
What Bitcoin Staking Means for Stacks
Bitcoin Staking is the product Stacks has been building toward for years: a BTC yield that leaves the coins on Bitcoin and is funded by bitcoin rather than inflation. With about 735 BTC bonded in its first two periods against a 3,000 BTC first tranche, it is early but already shows demand from institutions and pooled holders alike.
You can position around its growth with the STX/USDT spot pair on LeveX, or trade STX perpetual futures long or short as bonding data comes in. More explainers on Bitcoin-focused tokens live in Crypto in a Minute.
