Overview

Welcome to the Pendle Documentation. This overview provides key information and resources to help you understand and integrate with the Pendle protocol.

Understanding Pendle's Architecture

• Start with Pendle's High Level Architecture for an overview of the components in the Pendle protocol.
• Pendle's Standardized Yield (SY) have quite a number of nuances to it, refer to the StandardizedYield documentation to understand the different types of SY and how they work.
• Explore the developer documentation on vePENDLE to understand the components and cross-chain mechanisms of vePENDLE.
• Also check out Uncategorised Questions for answers to common questions.
• To see the latest Pendle's contracts, refer to Pendle Contract Repo
• To see examples of various contract interactions, refer to Pendle Examples Repo

On-chain Integration

Interact with Pendle Router

• To learn more about the Router and its functions, refer to PendleRouter.
• To generate calldata for on-chain operations such as buying PT, adding liquidity into a market, or redeeming yield, refer to Pendle's Hosted SDK.

Interact with Pendle Oracles

• To get the price of PT, YT, and LP, refer to How To Integrate Oracles.
• To learn more about using PT and LP as collateral, refer to PT as Collateral & LP as Collateral.

Off-chain Integration

• To query data on prices of PT, YT, LP, APY of pools, and other data, refer to Pendle's Backend. The Backend has a high rate limit and is also the source of data for Pendle DApp.
• To perform various on-chain calculations without using the Backend, refer to Pendle's RouterStatic. This is a low-level system built in Solidity, consisting of on-chain computational and data aggregation functions. Note that this is not to be used for on-chain integration since the contracts are not audited.

Limit Order System

• To learn more about Pendle's Limit Order System contract, refer to LimitOrderContract.
• To learn how to Create, Cancel, Fill Limit Orders, refer to the respective files.

Whitepaper

For a deeper dive into the mechanics and formulas involved in the Pendle protocol, refer to the four whitepapers at this link:

• SY: Explains EIP-5115 Standardized Yield, a token standard to generalize yield-generating mechanisms.
• SYS: Explains how Pendle splits 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.
