As DeFi continues to evolve, more and more users are starting to focus on how to achieve more stable and efficient yields on-chain. The protocol has proposed two key components - tAssets and DOR - attempting to bring a 'fixed income' experience similar to traditional finance to DeFi.

tAssets is a new type of liquid staking asset that not only earns staking rewards but also brings additional earnings through protocol strategies; DOR is a mechanism for generating on-chain interest rate benchmarks, helping to establish a unified, transparent, and manipulation-resistant interest rate system. Furthermore, the protocol connects users, quote providers, and incentive mechanisms in the ecosystem through its native token, enhancing system security and participation.

This article will explain in a simple and easy-to-understand manner what tAssets and DOR are, how to use them, their value, and how they open new earning opportunities for DeFi users.

I. tAssets

  • One-sentence Introduction

tAssets is a new type of DeFi yield asset designed to provide users with annualized returns higher than traditional liquid staking and to integrate various DeFi application scenarios.

  • How It Works

When you deposit ETH or other supported liquid staking tokens (such as stETH) into the Treehouse protocol, you will receive the corresponding tAssets (for example, tETH). Its yield comes from three sources:


1️⃣ Staking Rewards: Stake assets in protocols like Lido to earn basic PoS rewards;

2️⃣ Interest Rate Arbitrage: Use low-interest collateral to borrow ETH and then reinvest to increase total returns;

3️⃣ Value Accumulation: tAssets use a non-rebase model, where its price increases with revenue growth without increasing quantity, and rewards don't need to be manually claimed.

  • Product Highlights

✅ Higher Returns: Compared to ordinary staking, there are additional arbitrage gains;

✅ No Operation Required: Earnings are automatically reinvested, no manual claiming needed;

✅ Strong Compatibility: Non-rebase design, compatible with most DeFi protocols;

✅ Flexible Use: Can be used as collateral, participate in liquidity pools, access lending platforms, etc.

  • Suitable Audience

DeFi users looking to enhance ETH or LST yields;

Long-term holders who hope to simplify operations and automate compounding;

Participants in DeFi strategies looking for efficient capital utilization.

II. DOR (Decentralized Offered Rates)

  • One-sentence Introduction

DOR is an on-chain benchmark interest rate mechanism aimed at providing transparent, fair, and unmanipulable reference rates for DeFi.

In traditional finance, interest rates like LIBOR and SOFR face many problems, such as centralization, lack of transparency, and even past manipulation scandals. DOR addresses these structural defects through decentralized design, pushing the on-chain interest rate market towards a more mature and trustworthy future.

  • Architecture Composition

Operator: Create and maintain the interest rate setting mechanism (such as the ESR curve), manage system parameters, and select participants;

Panelist: Submit interest rate predictions and stake capital; accurate predictions can earn rewards;

Delegator: Delegate tAssets to trusted Panelists, share their rewards and enhance system security;

Referencer: Integrate DOR into their own products (such as lending platforms, pricing models) to promote actual usage;

User: Use DOR-based interest rates in financial products, such as lending, swaps, options, etc.;

  • Core Value

✅ Manipulation Resistant: All interest rate predictions are jointly participated by multiple independent roles, verifiable on-chain to avoid control by a few individuals;

✅ Incentive Driven: Participants need to stake capital; accurate predictions will earn rewards, while errors face penalties;

✅ Broad Adaptability: DOR can serve as a core interest rate source for stablecoin issuance, interest rate derivative pricing, and fixed-income product construction;

✅ On-Chain Transparency: All data and prediction processes are open and transparent, auditable and traceable;

✅ Forward-Looking Predictions: Unlike SOFR, which only records past transaction rates, DOR supports predictions of future rates, making it more suitable for financial contract needs.

  • Suitable Audience

Investors looking for reliable interest rate references in DeFi;

Users who want to participate in on-chain interest rate predictions, stake, and earn rewards;

Developers building stablecoins, interest rate products, and derivative protocols;
