📜License

The Phase Protocol is licensed under the Business Source License 1.1, which disallows forks until the license changes to the provided open-source license. You are allowed to use, modify, and copy certain parts of Phase. You can use interfaces in your codebase to interact with and extend the protocol. There are also exceptional cases where you can fork the code, such as proxies. These are case-by-case situations and must be explicitly permitted by the Phase Foundation.

There might be cases where source code not owned by Phase is accidentally tagged under the BSL 1.1 license, and when such cases are reported to the team they will be swiftly fixed.
