License Information

Protocol Smart Contracts

The Textile Protocol v2.1 smart contracts are licensed under multiple licenses to balance open-source principles with business requirements.

Business Source License 1.1 (BUSL-1.1)

Applies to: Core protocol contracts

The main protocol contracts are licensed under the Business Source License 1.1:

• Commercial Use Restriction: The licensed work may not be used for production purposes by any party other than Textile or its authorized licensees during the restriction period
• Change Date: 4 years from the date of release
• Change License: After the Change Date, the license automatically converts to GPL-3.0-or-later
• Development & Testing: Unrestricted use for development, testing, and non-production purposes

Rationale: This approach allows the protocol to mature and establish itself while ensuring it becomes fully open-source over time.

MIT License

Applies to: Utility libraries and interfaces

Supporting libraries, interfaces, and utility contracts are licensed under the permissive MIT License, allowing unrestricted use, modification, and distribution.

GPL-3.0-or-later

Applies to: Contracts after Change Date

After the BUSL-1.1 Change Date expires, all protocol contracts automatically become available under GPL-3.0-or-later, ensuring long-term open-source availability.
