Morpho Blue is a noncustodial lending protocol implemented for the Ethereum Virtual Machine. Morpho Blue offers a new trustless primitive with increased efficiency and flexibility compared to existing lending platforms. It provides permissionless risk management and permissionless market creation with oracle agnostic pricing. It also enables higher collateralization factors, improved interest rates, and lower gas consumption. The protocol is designed to be a simple, immutable, and governance-minimized base layer that allows for a wide variety of other layers to be built on top. Morpho Blue also offers a convenient developer experience with a singleton implementation, callbacks, free flash loans, and account management features.

The protocol is described in detail in the Morpho Blue Whitepaper.

Morpho.sol contains most of the source code of the core contract of Morpho Blue. It solely relies on internal libraries in the src/libraries subdirectory.

Libraries in the src/libraries/periphery directory are not used by Morpho Blue. They are useful helpers that integrators can reuse or adapt to their own needs.

The src/mocks directory contains contracts designed exclusively for testing.

You'll find relevant comments in IMorpho.sol, notably a list of requirements about market dependencies.
