Deep Dive
1. Complete UI Stack Rebuild (2023)
Overview: The team rebuilt its user interface from the ground up to handle the complexity of Bitcoin-Stacks cross-chain interactions. This results in a more robust and reliable app for end-users.
During its testnet phase, Zest Protocol recognized the need for a more powerful interface. The new UI stack is significantly more complex than typical Ethereum DeFi apps and is the first of its kind for Bitcoin-Stacks, designed to rival projects like ThorSwap in functionality. This work was done in close collaboration with Hiro Systems on supporting infrastructure.
What this means: This is bullish for ZEST because it creates a smoother, more reliable experience for users when they deposit BTC or interact with the protocol. A better interface helps attract and retain users, which is crucial for a lending platform's growth.

2. Key Infrastructure & Library Upgrades (2023)
Overview: The team made essential upgrades to the Stacks-Bitcoin library and designed new transaction formats, allowing users to deposit BTC from any wallet type.
This technical work upgraded the underlying library so users can send BTC to Zest Protocol using Legacy, SegWit, Taproot, or other Bitcoin addresses. The team also designed a "peg-in wire format" that gives Stacks smart contracts their own Bitcoin addresses, enabled by sBTC.
What this means: This is bullish for ZEST because it removes a major technical barrier for users. By supporting all Bitcoin address types, the protocol becomes much more accessible to a wider range of BTC holders, potentially increasing its user base and total value locked.

3. Second Smart Contract Security Audit (2023)
Overview: Zest Protocol passed a second independent security audit, conducted by Least Authority, complementing an earlier audit from Coinfabrik in 2022.
This audit focused on the protocol's smart contracts, which manage user funds and loans. Passing this audit helps verify the security and reliability of the core system before mainnet launch.
What this means: This is bullish for ZEST because strong security is the most critical feature for a DeFi lending protocol. Successful audits build trust with users and institutions, assuring them that their capital is protected, which is essential for attracting significant deposits.

Conclusion
Zest Protocol's development trajectory shows a strong focus on building robust, user-friendly, and secure infrastructure to unlock Bitcoin for DeFi. The recent codebase work lays a critical foundation for its upcoming mainnet launch and future growth. How will the upcoming Bitcoin Collateral Vaults expand this technical foundation to bring lending directly to Bitcoin L1?
