Scrypto Yield Derivatives Challenge is Live | The Radix Blog | Radix DLT

The Scrypto challenges are back! This time, you’re invited to delve deep into the world of yield derivatives. Get ready to test your skills and build the next Pendle-like dApp in the Radix Network. Prizes include 15k USD in XRD, exclusive NFTs, and a fast-track to a Booster Grant!

The concept of yield derivatives is critical to the DeFi ecosystems but has not yet gained widespread adoption despite being an innovative concept that offers significant potential benefits. It’s time to show the true potential of DeFi on Radix! 

Find everything you need to enter the challenge below. The challenge starts now and the submission deadline is April 24th. Good luck!  

What are Yield Derivatives?

Yield derivatives or interest rate derivatives are financial instruments that derive their value from the yield of the underlying asset. There are different classes of yield derivatives in TradFi, but we’ve begun to see some of their implementation in DeFi, such as interest rate swaps with protocols such as IPOR or yield stripping protocols like Pendle. Yield stripping protocols have gained more steam in DeFi given the popularity of yield-bearing assets such as Liquid Staking Units (LSU) and Liquidity Provider (LP) tokens. 

These yield-bearing assets are tokenized to strip the yield from the principal, splitting the yield-bearing asset into two parts: Principal Token (PT) and Yield Token (YT), essentially creating two derivatives of the underlying asset. With these two derivatives existing, the underlying asset is subject to a maturity date before being redeemed. The PT portion gives you the right to the principal of the token, while the YT gives you the right to the future yield of the token. 

With these two separate derivative tokens, a trader can speculate on either portion of the underlying asset as parts rather than as a whole. For example, once you have YT and PT, you may speculate on the YT portion (yield of the underlying asset) while keeping your PT (principal of the underlying asset). The flexibility and optionality offer great benefits to the trader. 

Here’s how it generally works and some benefits associated with it:

Overall, yield derivatives introduce new opportunities for investors to efficiently access and manage income-generating assets within the decentralized finance ecosystem. It enhances liquidity, flexibility, and accessibility while also offering potential benefits in risk management.

Yield Derivatives on Radix

Building a yield derivatives protocol on Radix offers several benefits:

In summary, Radix’s tech stack is uniquely aligned with the characteristics of this specific niche in DeFi, making it an ideal environment for developing applications like a yield derivatives protocol.

The Scrypto challenge

The Scrypto challenge involves building a yield derivative platform using the Radix Tech Stack.

  1. Understand the concept of yield derivatives
  2. Build a Scrypto package for a yield derivatives platform
  3. Integrate the Scrypto package with a front-end interface and the Radix DApp Toolkit

What you could build

Yield derivatives offer a rich field for innovation in DeFi, and you can combine financial ingenuity with Radix technology. We encourage you to blend imagination with practicality. Here is a guide to spur your creativity:

Project Inspiration

Yield Stripping

Imagine a platform where users can tokenize a staking pool’s future yield with your own features. Dive into separating a financial instrument’s yield component from its principal. This creates two distinct assets (YT and PT). This mechanism allows users to manage immediate liquidity needs while retaining exposure to future earnings.

Interest Rate Swaps

Develop a scrypto-based dApp, focusing on accurate and decentralized interest rate information, to facilitate more efficient and transparent rate swaps. Explore the development of platforms enabling users to swap their expected yields based on different interest rates. This concept is essential for managing interest rate exposure and can provide stability in volatile yield environments.

Yield Swapping Platform

You could build a Swapping Platform specifically designed for trading yield derivatives, where users can trade the yields they expect from different DeFi products. This can include both fixed and variable yields, offering users a way to diversify and hedge their yield exposure.

Yield Derivative Examples

Pendle Finance

Directly uses yield derivatives by allowing users to tokenize future yield. This is done by separating the future yield component from the underlying asset. Users can sell or trade these yield tokens, which represent the right to future streams independently of the underlying asset. This innovation effectively creates a new market for yield, where risks and returns associated with future yields can be separately managed.

Notional Finance

Notional Finance’s approach, particularly with fixed-rate lending and leveraged vaults, offers a nuanced view of yield management in Defi. Their products create opportunities for users to engage with yield in more controlled and predictable ways, resembling aspects of yield derivatives by locking in returns and managing risks.

Tranche Finance

Tranche Finance is integrated with other DeFi protocols, providing two types of tranches (fixed and variable) for each listed asset. When a user deposits an asset into Tranche, it automatically begins generating yield though the relevant DeFi protocol. In return, the user receives a Tranche Token (either A for fixed or B for variable rates) plus any yield generated.

Additionally, users have the option to earn yield by depositing into either the fixed-rate Tranche A or the variable-rate Tranche B. The variable returns are influenced by the underlying protocol and other Tranche deposits.

IPOR, standing for Inter-Protocol Offered Rate, plays a crucial role in the evolution of yield derivatives in DeFi. It provides a reliable reference rate, essential for pricing and valuing interest rate derivatives much like what a yield curve does in TradFi. This innovation paves the way for more advanced financial instruments in DeFi, enabling market participants to either hedge or speculate on interest rate fluctuations. By using decentralized liquidity pools as counterparties in these derivatives, IPOR simplifies market processes and supports the development of a yield curve in DeFi, crucial for the valuation of yield derivatives. The presence of IPOR in the market could transform how yield risks are managed and offer new investment opportunities in the DeFi space.

Gearbox Protocol

Gearbox offers a platform for leveraged liquid staking. Users can enhance their staking yields by borrowing assets, which increases their staking power and generates additional returns in the form of stETH. The platform also features lending pools where users lend assets and earn returns without facing impermanent loss. These returns are a combination of interest from borrowers and potential additional token rewards. Gearbox’s approach enables users to maximize their yield strategies in DeFi, leveraging assets to enhance returns while managing risks associated with market fluctuations.

Implementation Example

To assist with the challenge, we’ve provided an example Scrypto package which has a basic implementation of a “yield tokenizer” and Pendle Finance’s V2 AMM. The example is optional and if used, can be reworked or expanded to fit your needs. It is only meant to provide a reference of how it could look like in Scrypto and may assist you in understanding how a yield derivative protocol works.
