How Pendle Works

To understand how Pendle works on the contract level, you can:

  • Start with Pendle's High Level Architecture for an overview of the components in Pendle protocol.

  • Refer to the developer docs on vePENDLE to understand the components and cross-chain mechanisms of vePENDLE.

  • Refer to the repository for Pendle V2 contracts: GitHub link

To understand the deeper mechanics and formulas involved in the Pendle protocol, you can refer to the 4 whitepapers at this link:

  • SY: explains EIP-5115 Standardized Yield, a token standard to generalize yield generating mechanisms;
  • SYS: explains how Pendle split any Standardized Yield token into Principal Tokens and Yield Tokens;
  • V2_AMM: explains how the AMM works in Pendle V2;
  • vePENDLE: explains how vePENDLE works;

How to Integrate Pendle

For on-chain contract systems building on top of Pendle

For off-chain systems building on top of Pendle:

Pendle provides three key services to support developers in leveraging the Pendle protocol.

  • Pendle's RouterStatic: This is a low-level system built in Solidity, consisting of on-chain computational and data aggregation functions. You can find additional details here.
  • Pendle's Hosted SDK: This is a collection of APIs designed to generate calldata for on-chain operations, such as buying PT, zapping into a market, or redeeming yield. More information is available here.
  • Pendle's Backend: This comprises a set of APIs designed to integrate on-chain and off-chain data, covering aspects like spot and historical prices of various assets, APYs of different markets, and a list of transactions for a market. Further details can be found here.

For mobile wallets who want to feature Pendle Earn in your app:

  • Pendle Earn is already optimized for mobile usage
  • You just need to add a link or shortcut for users to navigate to the Pendle Earn app at
  • If your wallet is not supported on Pendle yet, please reach out to us by creating a ticket at the #collab-ticket channel in our Discord at
