The greatness of a financial product lies not only in how it creates value for users but also in how it provides users with safe, transparent, and flexible exit paths.

The greatness of a financial product lies not only in how it creates value for users but also in how it provides users with safe, transparent, and flexible exit paths. In the critical link of asset redemption, the design of the Treehouse protocol demonstrates a profound understanding of user experience and system robustness. It discards a single, rigid model and instead constructs a layered, multi-path intelligent redemption system.

The core of this system is to provide optimal solutions for users with different scales and timing needs.

Standard channel: Born for liquidity and efficiency

For the vast majority of everyday, small redemption needs, Treehouse provides an efficient, immediate path.

When your redemption amount is within the 'Redemption Band' (currently set to 0 to 200 wstETH), your request will be fulfilled through the dedicated tETH/wstETH Curve liquidity pool established by the protocol. This means that your tETH can be almost instantly exchanged for wstETH, making the entire process smooth and akin to trading on a top-tier decentralized exchange.

Even more reliable, this liquidity pool also integrates a proprietary safety mechanism developed exclusively by Treehouse—'Protocol Own Anchoring Protection' (PPP). This innovative design provides an additional solid guarantee for the pool's stability, ensuring that even during market fluctuations, users' regular redemptions can be reliably executed.

Large channel: Prudent and stable coordinated exit

When a user's redemption demand exceeds the upper limit of the 'Redemption Band', the protocol will initiate a more prudent and stable process. This is not a restriction but a protective mechanism responsible for all participants in the pool.

In this case, users can choose to interact directly with the Treehouse protocol, redeeming their held tETH in exchange for their corresponding share in the underlying asset pool. This share will be based on the real-time tETH:wstETH exchange rate displayed on the dashboard.

However, to complete this process, the protocol needs to perform a series of complex 'unpacking' operations in the background, including withdrawing LSTs used as collateral from the lending platform, unstaking LSTs back to native ETH, and repaying previous loans incurred for arbitrage. These operations, especially the unstaking of certain LSTs, can take several days. Therefore, to give the protocol ample time to orderly and harmlessly complete these steps, such large redemptions will have an approximately 7-day waiting period.

This design is crucial. It avoids being forced to inefficiently liquidate positions in the market due to a single large redemption, effectively protecting the interests of all remaining users in the pool and ensuring the stability and continuous growth of tETH value.

The cornerstone of fairness: transparent fees and value accounting

In order to maintain the fairness of the entire system, the final amount of large redemptions will follow a rigorous and transparent calculation principle.

The final quantity of assets redeemed will depend on a 'minimum value function': the protocol will calculate based on the lower value of the tETH/underlying asset and underlying asset/native ETH exchange rates at the two points in time of 'initiate redemption' and 'complete redemption'. This mechanism is designed to prevent any arbitrage behavior that exploits market fluctuations during the waiting period, ensuring fairness for all users.

In addition, to cover the interest costs and operational expenses incurred by the protocol during the 7-day waiting period, users will need to pay a small fee of 5 basis points (0.05%). This fee is not for the protocol's profit but is used to ensure that the costs of the redemption process are not passed on to other users in the pool, reflecting the maintenance of collective interests.

Fast channel: Designed for extreme timeliness

Finally, Treehouse also offers a 'fast redemption' option for users with the highest and most immediate liquidity demands. Through this channel, users can bypass all waiting periods and immediately withdraw their corresponding wstETH assets from the strategy vault within the set limits. To balance the adjustment costs brought by this immediacy to the protocol strategy, a fixed fee of 2% will be charged for fast redemptions.

In summary, Treehouse's redemption process is a thoughtful, multi-layered financial engineering masterpiece. It perfectly balances the diverse needs of users—whether pursuing efficiency, cost, or extreme speed—with the long-term stability and security of the entire ecosystem through three channels: standard, large, and fast. This ultimate pursuit of detail and comprehensive consideration of user interests is the foundation of Treehouse protocol's trustworthiness and paves the way for future ecological prosperity under governance.
