- Stacks outpaced Rootstock by $5.7 million at the close of the third quarter, generating $448,000 in quarterly fees—more than double Hemi’s $208,000 and Merlin’s $181,000.
- Growth was driven by the July 2026 PoX-5 hard fork, which launched mainnet Bitcoin staking and attracted approximately 735 $BTC alongside 493 million staked $STX.
- DeFi activity on Stacks remains heavily concentrated, with lending accounting for 92.1% ($81.9 million) of total DeFi TVL, predominantly led by Zest Protocol before overall chain TVL retraced to roughly $57 million in early November 2026.
Stacks Surpasses Bitcoin Layer Competitors in Third-Quarter Performance
Stacks concluded a competitive third quarter by securing a leading position in the Bitcoin layer ecosystem, outpacing rival network Rootstock by $5.7 million. Network adoption also yielded substantial revenue, with Stacks generating $448,000 in quarterly fees. This figure more than doubled the $208,000 posted by Hemi and significantly exceeded Merlin’s total of $181,000. Momentum culminated toward the end of the quarter as weekly decentralized exchange (DEX) volume on Stacks peaked at $16.7 million in late September 2026.
PoX-5 Hard Fork and Liquid Staking Catalyze Capital Inflows
The turning point for the network arrived in July 2026, when Stacks deployed Bitcoin Staking on mainnet through the PoX-5 hard fork. The consensus upgrade established miner-funded yields distributed over fixed bonding cycles. Investor demand materialized quickly, with roughly 735 $BTC locked into staking over the initial two bonding periods following the rollout. Concurrently, participation across the native asset surged, elevating total $STX staking to 493 million $STX.
Ecosystem utility expanded further in early September 2026 with the introduction of liquid staking. Protocol provider StackingDAO introduced stBTC, a liquid tokenized representation of staked Bitcoin designed to retain liquidity and composability across decentralized finance protocols while underlying assets accrue yield.
Lending Protocols Dominate Network TVL via Zest Protocol
By September 30, 2026, decentralized lending emerged as the definitive driver of on-chain capital, representing 92.1% of total decentralized finance (DeFi) total value locked (TVL) on Stacks, equivalent to $81.9 million. Zest Protocol served as the network’s focal liquidity hub, commanding the primary share of locked capital. At the close of the quarter, Zest Protocol disclosed over $122 million in deposits and $42 million in active borrowed assets.
However, broader market conditions triggered a contraction post-quarter. By early November 2026, the native Stacks chain TVL retracted to approximately $57 million. Despite fluctuations in primary chain metrics, the aggregate Stacks ecosystem stood at approximately $123 million when accounting for liquid staking alongside foundational DeFi protocols.
Why This Matters
Because the Bitcoin base layer was intentionally designed with structural limitations to prioritize security over complex smart contracts, networks such as Stacks, Rootstock, Mezo, Hemi, and Merlin are competing directly for locked liquidity from the same global pool of Bitcoin holders. The third-quarter trajectory demonstrates that introducing native yield mechanisms can successfully mobilize otherwise idle $BTC reserves.
Nevertheless, the data highlights significant structural risks. With lending comprising 92.1% of DeFi TVL and Zest Protocol maintaining outsized dominance, the network remains acutely vulnerable to sector-specific shocks. Furthermore, the drop to approximately $57 million in November indicates that a $5.7 million margin over Rootstock provides little insulation against sudden liquidity shifts in the Bitcoin layer landscape.
Frequently Asked Questions
What led to Stacks’ growth in the third quarter of 2026?
The primary growth catalyst was the July 2026 PoX-5 hard fork, which activated mainnet Bitcoin staking with miner-funded yields. This brought approximately 735 $BTC into staking, pushed $STX staking to 493 million, and was bolstered in September by StackingDAO’s launch of the liquid staking token stBTC.
How concentrated is DeFi activity on the Stacks network?
DeFi activity on Stacks is heavily centralized within lending markets, which represented 92.1% ($81.9 million) of the network’s total DeFi TVL at the end of September 2026. Zest Protocol held the dominant position in this sector, reporting upwards of $122 million in deposits and $42 million in borrows.
What was Stacks’ total value locked (TVL) by early November 2026?
By early November 2026, Stacks’ direct on-chain TVL had pulled back to approximately $57 million. However, when combining core DeFi protocols with liquid staking capital, the wider Stacks ecosystem accounted for roughly $123 million.
