Zest Protocol loans jump 132% to $14.75M in Q3 before new lending is paused
In brief
- Zest's Stacks V2 market loans rose 132% in Q3 2026, per Alea Research.
- Net new borrowing drove about $6.20 million of the increase; higher token prices added $2.18 million.
- Borrows passed $40 million in early October, then settled near $25 million.
- Zest paused new lending on October 30, citing external market conditions.
What drove the Q3 growth
Most of it was fresh borrowing. Alea Research's on-chain breakdown of the quarter puts about $6.20 million of the increase down to net new borrowing, and another $2.18 million to higher token prices. In other words, it wasn't just a price effect.
Some background helps here. Stacks is a network built to bring smart contract functionality to Bitcoin-backed assets, and Zest was founded in 2023 out of work at Trust Machines. Its V2 upgrade arrived in early 2026 and introduced risk groups, a mechanism meant to improve capital efficiency while keeping risk in check.
On September 23, Zest launched a mainnet demo of its Bitcoin Collateral Vaults. Users deposit native BTC into self-custodial vaults and borrow USDC on Ethereum (no wrapping, no bridging). By early November, users had opened 135 vaults, Crypto Briefing reported.
A peak, then a pullback
Activity kept climbing after the quarter closed. Crypto Briefing reported that in early October, borrows on the Stacks market passed an all-time high above $40 million, and TVL reached $87.28 million (an 18.2% gain from September) before falling back. That peak didn't hold.
By early November, according to the same report, active loans had settled at about $25 million and TVL sat around $46.6 million. Cumulative fees had passed $540,000 as of early November, Crypto Briefing reported.
Then Zest stopped writing new loans.
On October 30, the protocol paused new lending, citing external market conditions, specifically a security incident involving Binance, Crypto Briefing reported.
The risk record
Zest's track record on liquidations is the other half of the story. Since its Stacks market went live in March 2024, Zest has processed more than 1,500 liquidations with zero bad debt, according to Crypto Briefing's report.
So is a pause like this unusual for defi? Alea Research doesn't treat it as an isolated move. It framed the halt as part of a wider pattern of DeFi protocols protecting themselves from external shocks.
Crypto Briefing didn't say when new lending will resume.
