Stacks reaches 1.6M total wallets as Bitcoin DeFi ambitions grow
Bitcoin has long been the asset everyone wants exposure to and the network nobody could build on. Stacks was designed to change that, and a new on-chain milestone suggests it is making progress.
The Stacks protocol has recorded 1.6 million total wallets that have ever received a transfer, according to on-chain analytics tracking cumulative user adoption.
What the wallet count actually tells you
What the 1.6 million figure tells you is the cumulative reach of the network, the total number of unique addresses that have had at least some interaction with the Stacks ecosystem at any point in its history. Not everyone is logging in daily, but the number sets a ceiling for potential reactivation and signals that the protocol has moved well beyond niche hobbyist territory.
A busy summer of product launches
On July 8, 2026, the protocol announced stBTC, a liquid staking token built to generate Bitcoin yield within the Stacks DeFi ecosystem. Instead of simply holding Bitcoin and earning nothing, users can stake it through Stacks and receive a liquid token that can be deployed elsewhere in DeFi while the underlying Bitcoin continues earning yield.
Five days later, on July 13, a proposal for the PoX-5 upgrade was put forward. PoX, which stands for Proof of Transfer, is the consensus mechanism that connects Stacks to Bitcoin by having miners transfer Bitcoin to participate in block production. The PoX-5 proposal introduces a new staking model and a 15% reserve fund, creating a buffer within the staking system designed to add stability and reduce the risk of yield disruption for participants.
Earlier in the summer, on June 17, Stacks announced an integration with Fireblocks, the institutional-grade digital asset custody and transfer platform. Fireblocks is the infrastructure layer that hedge funds, banks, and crypto-native institutions use to move and secure assets at scale, and the integration opens the door to a class of capital that previously had no clean on-ramp into the Stacks ecosystem.
The Nakamoto foundation
The Nakamoto release, completed in 2024, was the most significant technical upgrade in the protocol’s history. Before Nakamoto, Stacks blocks were tied to Bitcoin block production, meaning the network inherited Bitcoin’s roughly ten-minute confirmation window. Post-Nakamoto, the protocol produces blocks at a faster cadence. The two-way peg mechanism, sBTC, allows Bitcoin to move between the Bitcoin base layer and the Stacks layer without relying on a centralized custodian.
stBTC, announced this July, builds directly on top of sBTC.
What investors should watch
stBTC is the most direct catalyst to watch. Liquid staking tokens tend to generate flywheel effects: yield attracts deposits, deposits increase total value locked, higher TVL attracts more DeFi protocols, and more protocols attract more users.
The PoX-5 upgrade directly affects the incentive structure for STX holders who participate in stacking. The 15% reserve fund introduces a new variable into that calculus, and the market will need to price in both the stability benefits and any changes to effective yield rates once the upgrade is finalized.
The Fireblocks integration removes one of the primary friction points for funds that want Bitcoin DeFi exposure without building custom infrastructure.
