Stacks Market grows as Bitcoin capital becomes active
The Zest Protocol Stacks Market grew from $65M in July to $73.86M at the start of September, an increase of 13.63%. Total borrows were $6.70M, unchanged from July.
sBTC supply declined 7.02%, from 777 sBTC in July to 722.43 sBTC at the start of September. This may reflect depositors preparing for the Stacks Bitcoin Staking launch.
The larger signal is the market infrastructure now forming around Bitcoin on Stacks. Lending, Bitcoin-denominated yield, liquid staking, and automated strategies are beginning to work together in one market.
Zest Protocol Stacks Swap finds its users
Zest Protocol Stacks Swap continued attracting users in August, and the response has been strong. It routes trades across Stacks liquidity without charging an aggregator fee, giving users one place to find execution across the market.
The early reception supports a broader role for Zest Protocol on Stacks. Users can now lend, borrow, and swap through the same interface, with automated vault strategies coming next.
Levered Bitcoin Staking Vault opens private commitments
Bitcoin Staking gives BTC a new source of Bitcoin-denominated yield. stBTC makes that yield liquid and usable across Stacks DeFi while its backing and rewards remain denominated in sBTC.
The Levered Bitcoin Staking Vault is now taking private commitments ahead of the Stacks Bitcoin Staking launch. It is built on the existing Zest Protocol Stacks Market and is separate from Bitcoin Collateral Vaults.
Deposit stBTC, borrow sBTC against the deposited stBTC, stake the borrowed sBTC into more stBTC, repeat. The vault turns that sequence into one automated position.
Every loop borrows sBTC. If the vault attracts sustained use, it can increase sBTC borrow demand, market utilisation, protocol spread revenue, and the variable supply rate available to users supplying plain sBTC to Zest Protocol. Stacks is becoming a live proving ground for productive Bitcoin capital.
From the Stacks Market to the capital layer for Bitcoin
The Stacks Market is the live proof behind Zest Protocol's next chapter. It has shown that Bitcoin capital can support lending, borrowing, yield, and increasingly sophisticated financial products.
Zest Protocol is now expanding that work through Bitcoin Collateral Vaults, moving from productive Bitcoin capital inside one successful market to a capital layer that can serve any chain able to read a proof.
Bitcoin Collateral Vaults: public demo next
Internal testing of the Bitcoin Collateral Vaults mainnet demo is complete. August focused on preparing the product and launch materials for a coordinated public release.
Bitcoin Collateral Vaults let users borrow stablecoins against BTC or put its value to work on any chain that can read a proof. The BTC stays on Bitcoin, with no wrapping or bridging.
Security built as a continuous process
Zest Protocol Stacks Market V2 has been audited by Clarity Alliance, Asymmetric Research, and Greybeard Security. Zest Protocol also runs every released frontier AI model against the protocol through a continuous automated security harness, with zero valid bug reports since the start of 2026.
Audits are checkpoints. Security testing continues as the market and available testing systems evolve.
The audit reports and continuous AI security process are documented here.
Bitcoin's financial stack is expanding
Stacks now brings lending, liquid Bitcoin Staking, and automated yield strategies into the same market. Bitcoin Collateral Vaults extend that progression beyond a single Bitcoin L2.
Zest Protocol is moving from making Bitcoin productive within one market to making its value useful wherever proofs can travel.
