Stacks has crossed 1.6 million total wallets, the network announced this week. The milestone comes as the Bitcoin layer-2 protocol pushes deeper into decentralized finance with a trio of developments: a liquid staking token called stBTC, the upcoming PoX-5 upgrade, and an integration with institutional custody platform Fireblocks.
1.6 million wallets and counting
The wallet count is a key metric for Stacks, which uses a unique proof-of-transfer consensus mechanism tied to Bitcoin. Reaching 1.6 million suggests growing user adoption, even as the broader crypto market has seen mixed sentiment this year. The network didn't break down active versus total wallets, but the number is up from around 1 million earlier in 2026.
stBTC brings liquid staking to Bitcoin
Stacks is now involved in stBTC, a liquid staking token that lets users earn rewards without locking up their BTC. It's a familiar concept from Ethereum's Lido, but applied to Bitcoin's ecosystem. The idea: give Bitcoin holders a way to participate in DeFi while still earning stacking rewards on Stacks. The timing aligns with the broader push to bring more utility to Bitcoin beyond just holding.
PoX-5 upgrade on the way
The PoX-5 upgrade is the next iteration of Stacks' proof-of-transfer protocol. Details are still emerging, but the upgrade is expected to improve efficiency and security for the network's stacking mechanism. Stacks developers have been working on it for months, and the community is watching closely for a specific launch date.
Fireblocks integration opens institutional doors
Stacks has integrated with Fireblocks, the digital asset custody platform used by many institutions. That means Fireblocks clients can now custody STX and interact with Stacks-based applications. It's a practical step toward bringing institutional capital into Bitcoin DeFi, a space that has historically been dominated by Ethereum-based protocols.
The next concrete milestone to watch is the PoX-5 upgrade's activation. Stacks developers haven't announced a hard date yet, but the community expects more details in the coming weeks. For now, the network is betting that a combination of wallet growth, liquid staking, and institutional access can make Bitcoin DeFi a real contender.
