Stacks Leads Bitcoin-Linked DeFi With $88.9 Million at Q3 Close

Stacks closed the third quarter of 2026 with $88.9 million in decentralized-finance total value locked (TVL), the largest figure among networks built around Bitcoin (BTC).

Rootstock followed at $83.2 million. Mezo followed at $77.3 million. Stacks’ reported quarter-end figures put it ahead in Bitcoin-linked financial activity. The margins were narrow. The lead still placed Stacks at the top of a focused market for Bitcoin-based lending, token swaps and trading.

Apps on Stacks generated $448,000 in user fees during the quarter. Hemi generated $208,000. Merlin generated $181,000. Weekly trading volume on Stacks decentralized exchanges reached a $16.7 million peak in late September. Trading supplied a second measure of network use alongside the locked-value ranking.

Lending did the heavy lifting

At quarter-end, lending accounted for $81.9 million, or 92.1%, of Stacks’ DeFi TVL. Zest Protocol held the largest share of locked value. Stacks’ headline lead therefore rested mostly on lending. It also concentrated the network in one product category and one leading protocol.

The result gave the network a larger headline number with less diversification beneath it. Without Zest’s exact share, the total does not show how much value depended on that protocol. A reduction in the largest lending position could weaken the reported ranking. Lending exposure remains the central operating variable behind the headline result.

PoX-5 changed the staking mix

Bitcoin Staking went live on Stacks mainnet in July through the PoX-5 hard fork. The upgrade introduced miner-funded yields distributed through set bonding periods. Roughly 735 BTC was staked during the first two post-launch bonding periods. Staking of STX, the network’s token, reached 493 million STX after the upgrade.

The two systems gave the network distinct staking paths: one based on Bitcoin and another centered on STX. Bitcoin staking brought BTC into a miner-funded yield mechanism. The 493 million STX stacking figure showed the scale of native-token participation after the upgrade.

In early September, StackingDAO introduced stBTC, a token representing staked Bitcoin that can be transferred and used elsewhere. It gave Stacks a liquid-staking option alongside Bitcoin staking. Builders could route staked-Bitcoin exposure into other applications rather than leave it confined to a bonding position.

Scale and competition

Stacks operates its own consensus mechanism while anchoring to Bitcoin. Bitcoin’s base layer has a narrower role than applications for lending or token swaps. Stacks therefore competes with Rootstock, Mezo, Hemi and Merlin for activity in Bitcoin-linked finance.

A broad third-quarter DeFi TVL snapshot put total DeFi TVL at $95.42 billion on Sept. 26. Stacks’ $88.9 million was small against that wider market. It still led the narrower category built around Bitcoin. The comparison shows the limit of the claim: Stacks led its peers, but Bitcoin-linked finance remained a small segment of DeFi overall.

What does this change for Bitcoin-linked DeFi?

By early November 2026, one chain-level measure for Stacks stood at about $57 million. A broader ecosystem measure that included liquid staking was about $123 million. Neither directly matched the $88.9 million quarter-end DeFi TVL figure. The measures used different scopes, so their apparent rise or fall depends on what each one counted.

The November numbers do not show an unambiguous change from quarter-end. One is lower and one is higher. What they show is a measurement split between the chain itself and the wider ecosystem, including products such as liquid staking.

For users and builders, the practical change is a broader toolkit, not just a larger TVL headline. The Stacks ecosystem now combines Bitcoin staking, transferable staked Bitcoin through stBTC, lending activity and decentralized-exchange trading. Its main constraint is concentration. Lending supplied 92.1% of quarter-end TVL. Zest Protocol held the largest protocol share.

The next comparable quarter-end snapshot will provide the market-structure test: whether PoX-5 staking and stBTC convert the current TVL lead into broader fees and less concentrated activity.
