Midnight: Developer Resources

This page is your central hub for all the tools, links, and data sources you need to build on Morpho Midnight.

Data & Contracts

These resources are for interacting directly with the blockchain.

• Contract Specifications: For detailed function signatures, events, and errors, refer to the canonical contract specs:
  • Midnight Core Contract: immutable fixed-rate lending primitive via isolated permissionless markets
  • Midnight Bundler: atomic multi-step transactions (e.g., supply collateral + take in one call)
• GitHub Repositories:
  • Midnight: The core protocol contracts (Midnight.sol, interfaces, libraries).

Integration Methods

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

• Midnight REST API: Indexed onchain state (markets, positions, transactions, offer groups, and performance data).
  • API Reference: Morpho Midnight API examples
  • Base URL: https://api.morpho.org/v0/midnight/
  • Tutorials:
    • Lend at a fixed rate
    • Borrow at a fixed rate
    • Exit borrow at maturity
• Midnight SDK: TypeScript library for constructing offers, computing ticks, encoding payloads, and interacting with the protocol.
