Borrow: Developer Resources

This page is your central hub for all the tools, links, and data sources you need to build on Morpho's Borrow product (Morpho Markets).

Onchain Data & Contracts

These resources are for interacting directly with the blockchain.

Market Parameters: Every Morpho Market is defined by 5 immutable parameters. The easiest way to fetch these for all markets is via the Morpho API.
Contract Specifications: For detailed function signatures, events, and errors, refer to the canonical contract specs:
GitHub Repositories:
- morpho-blue: The core protocol contracts.
- public-allocator: The contract for just-in-time liquidity.

These tools provide easier access to onchain data for frontends, backends, and analytics.

Morpho API (Recommended): The simplest way to fetch comprehensive data about markets, their states, APYs, and user positions.

- Tutorial: Using the API for Markets
SDKs: A suite of TypeScript libraries to accelerate your development.
- @morpho-org/morpho-sdk: The default abstraction layer - ready-to-send transactions, plus core entity classes (@morpho-org/morpho-sdk/entities) and Viem-based fetchers (@morpho-org/morpho-sdk/fetch) for easy onchain data retrieval.
- @morpho-org/liquidity-sdk-viem: A specialized SDK to calculate available liquidity, including from the Public Allocator.
