Compose

Compose is a smart contract library built on the ERC-2535 Diamond standard. Its core idea is Smart Contract Oriented Programming (SCOP), which breaks contracts into small, independent facets that can be combined and reused. Developers can deploy a diamond once and add or replace functions by attaching different facets, avoiding the need to redeploy entire contracts.

The main problem it solves is the high cost and risk of upgrading traditional contracts. In conventional designs, upgrading usually means migrating all data or relying on proxy patterns, which are complex and error-prone. Compose simplifies this by allowing modular upgrades at the function level, while all facets share the same storage, making data management consistent and straightforward.

Its competitive edge lies in intentional simplicity and code readability. The project deliberately restricts certain Solidity features to encourage clearer, safer code. It also promotes composition over inheritance, meaning developers can build new functionality by assembling existing, audited facets rather than writing everything from scratch.

In the past six months (2026-03 to 2026-09), the project has remained in early development. It is explicitly not production-ready, and access is limited to contributors. No major feature releases or public milestones were confirmed during this period. The library is still experimental, and users should treat it as a research-level tool rather than a stable dependency.
