EIP-2535

EIP-2535, commonly referred to as the Diamond Standard, is the official Ethereum Improvement Proposal that defines the multi-facet proxy contract architecture. It provides a standardized way to create upgradeable, modular smart contracts that can exceed the 24KB bytecode size limit imposed by the EVM.

The proposal details the interface for managing facets, including adding, replacing, and removing functions. By following this standard, developers ensure compatibility with tools and explorers that recognize the Diamond structure.

It has become a critical standard for building robust and scalable decentralized applications in the financial sector.
