The DeFi OS License is an open-source legal framework designed specifically for decentralized finance (DeFi) protocols and DAOs. It bridges the gap between the openness of blockchain-based code and the realities of governance, legal risk, and contributor protection.
Developed by STORM Partners’ legal team, the license enables DAO and protocol teams to align code, governance, and legal rights, without compromising innovation or permissionless principles.
Traditional open-source licenses like the MIT License, GNU GPL, or Creative Commons were built for centrally managed Web2 software. They don’t address the unique challenges of permissionless, on-chain systems, including:
When code governs capital, outdated licensing creates a structural risk for your project and its community.
The DeFi OS License (DeFOSS) is the first open-source license engineered for decentralized finance ecosystems. It preserves the freedoms of open source while introducing safeguards, governance alignment, and contributor protections for a permissionless environment.
With the DeFi OS License, DAOs and protocol teams can:
This is not about restricting innovation; it’s about licensing with intent, ensuring open code serves your community, contributors, and long-term roadmap.
Align protocol code with governance rules and protect project longevity
Reduce contributor risk and clarify enforcement mechanisms
Preserve credit, define derivative-use conditions
Build resilience against extractive or hostile forks
No license can prevent all forks. The DeFi OS License ensures forks are clearly attributed, follow governance-approved conditions, and remain distinguishable from your official protocol.
Yes. It combines recognized copyright protections with optional on-chain enforcement and DAO governance mechanisms, creating both legal and practical compliance pathways.
Add the license to your repository, update attribution notices, and (optionally) integrate governance or smart contract checks. The Implementation Guide explains each step.
It is not a drop-in amendment to other licenses, but it can work in a multi-license setup. We recommend a legal review for compatibility with AGPL, MIT, or other frameworks.
