Orca, a prominent decentralized exchange (DEX) on the Solana blockchain, has recently rolled out a significant update to its user interface (UI). This enhancement focuses on supporting tokens that utilize the Interest Bearing Extension (IBE), a feature introduced by Solana. The update aims to provide greater transparency and improve the trading experience for users dealing with interest-bearing tokens (IBT). Let's break down what this means and how it impacts the DeFi landscape.

What Are Interest-Bearing Tokens?

Interest-bearing tokens are a type of cryptocurrency that accrue interest over time. Unlike traditional tokens, where the value might fluctuate based on market dynamics, IBTs are designed to increase in value due to an embedded interest rate. This interest is often backed by underlying assets such as bonds or staking yields, making them a hybrid between traditional finance and decentralized finance (DeFi).

The Interest Bearing Extension, part of Solana's Token-2022 program, allows token issuers to set an on-chain interest rate directly on the mint account. This means the interest compounds continuously based on the network's timestamp, providing a seamless and transparent mechanism for users to track their earnings.

Orca's UI Enhancement

Orca's latest update integrates support for the IBE, ensuring that users can see the accrued interest on tokens when trading and searching for liquidity pools. This is a game-changer for several reasons:

1. Transparency: Users can now see both the token price and the accrued interest in one total value, making it easier to understand the real-time value of their investments.
2. User Experience: The UI now reflects the current on-chain price, which includes the interest component, offering a more accurate representation of the token's worth.
3. Liquidity Provision: When providing liquidity, the displayed value accounts for the on-chain price, ensuring that liquidity providers are fully aware of the dynamics involved.

A Live Example with Etherfuse

To illustrate the practical application of this update, Orca highlights Etherfuse, a project that issues tokenized government bonds on Solana. Etherfuse's Stablebonds are fully backed by the Mexican Government and utilize the IBE to display yield. This integration provides both institutional and retail investors with enhanced security and transparency.

For instance, when trading Etherfuse's CETES/USDC pair on Orca, users can now see the interest rate applied to CETES tokens, which are interest-bearing. This feature not only aids in making informed trading decisions but also aligns with Orca's mission to pioneer DEX support for such extensions, thereby extending better visibility to any project using the Interest Bearing Extension.

Implications for DeFi

Orca's support for interest-bearing tokens is a significant step forward in the DeFi space. It addresses a critical need for clarity and transparency, which are often lacking in complex financial instruments. By making interest rates visible and integrating them into the trading and liquidity provision processes, Orca is setting a new standard for user-centric design in decentralized exchanges.

Moreover, this update aligns with the broader trend of tokenizing real-world assets (RWAs), as seen with Etherfuse's Stablebonds. The tokenized Treasury market has seen a surge, reaching nearly $700 million by early 2025, indicating a growing interest in such financial products. Orca's enhancement ensures that users can engage with these products more confidently and efficiently.

Conclusion

Orca's latest UI update is a testament to the platform's commitment to improving user experience and transparency in the DeFi ecosystem. By supporting interest-bearing tokens through the Interest Bearing Extension, Orca is not only enhancing its own platform but also contributing to the broader adoption of innovative financial instruments on the Solana blockchain. As the DeFi landscape continues to evolve, such updates will play a crucial role in shaping the future of decentralized finance.

For those interested in exploring this feature, Orca's platform is now live with full support for IBTs, offering a glimpse into the future of transparent and user-friendly DeFi trading.
