EIP-2535 Diamond

The Beanstalk contract is a Diamond – a multi-facet proxy defined in EIP-2535 that can implement functionality from numerous different Facet contracts.

All the Facets share a common storage through the AppStorage pattern. Functionality is shared between Facets through internal Libraries.

Understanding EIP-2535 really helps to understand Beanstalk. This page serves as a resource hub for EIP-2535.
