Earn: Developer Resources

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

Onchain Data & Contracts

These resources are for interacting directly with the blockchain.

• Vault Addresses: While you can find a static list of all core contracts on the main Addresses page, the best way to dynamically fetch all deployed vaults is via the Morpho API.
• Contract Specifications: For detailed function signatures, events, and errors, refer to the canonical Morpho Vaults Contract Specs.
• GitHub Repositories:
  • metamorpho-v1.1: The latest immutable vault implementation.
  • metamorpho: The original vault implementation.

Offchain Data & Tools

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

• Morpho API (Recommended): The simplest way to fetch comprehensive data about vaults, their states, APYs, and user positions.
  • API Playground: api.morpho.org/graphql
  • Tutorial: Using the API for Vaults
• Morpho Subgraphs: For developers who prefer querying via The Graph protocol.
  • Tutorial: Using Subgraphs for Vaults
• SDKs: A suite of TypeScript libraries to accelerate your development.
  • @morpho-org/blue-sdk: Core, framework-agnostic classes for entities like Vaults and Markets.
  • @morpho-org/blue-sdk-viem: Adds Viem-based fetchers to the core SDK classes.
  • @morpho-org/simulation-sdk: Simulates user interactions to predict outcomes before sending a transaction.
  • @morpho-org/bundler-sdk-viem: The essential tool for creating one-click user experiences by bundling multiple actions.

Code & Examples

• Example Application: The earn-basic-app is a minimal but complete example of a React application for interacting with Morpho Vaults.
• Solidity Snippets: The morpho-blue-snippets repository contains simple, educational Solidity contracts for common vault interactions.
