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 the factory (the main address used to deploy all vaults) list of all core contracts on the main Addresses page, the best way to dynamically fetch all deployed Morpho 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:
- vault-v2: The V2 version of Morpho Vaults.
- metamorpho-V1.1: The latest Vault V1 implementation.
- metamorpho: The original Vault V1 implementation.

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.

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.
