In the field of Decentralized Finance, interest rates have always been as unpredictable as the weather, making them hard to grasp. However, Treehouse is undertaking a seemingly ordinary yet significant task: transforming interest rates into infrastructure on the Blockchain.

The importance of interest rates as infrastructure is self-evident. Whether it is lending, re-staking, stablecoin minting, or DAO treasury configuration, almost all Decentralized Finance protocols rely on interest rate logic. Without a unified, transparent, and structurally stable interest rate standard, the large-scale application of DeFi will always face challenges.

The TESR (Treehouse Ethereum Staking Rate) launched by Treehouse can be seen as "the interest rate tap" on the blockchain. Just like we can obtain a water source by turning on the faucet, developers can also easily call the TESR when writing smart contracts. This interest rate indicator is composed of multiple factors, including on-chain real data, ETH staking yields, and backtesting of arbitrage strategies, updated regularly and fully transparent, providing a reliable interest rate reference for all smart contracts.

This initiative marks the first step in the construction of interest rate infrastructure: standardization and ease of access. However, having a water source is not enough; a 'pipeline' is also needed to deliver and utilize this 'water'. This is where tAssets (such as tETH) come into play. tETH is pegged to TESR and has structured yields, allowing it to be used as collateral, a pegged asset, or a composite asset across various protocols, becoming a practical carrier of interest rate logic.

By building such an interest rate infrastructure, Treehouse is creating a more stable, transparent, and efficient financial environment for the DeFi world, laying the foundation for future innovation and development.
