Join the highly active and supportive community on the Susbstrate Stack Exchange to ask questions about use and problems you run into using this software. Please do report bugs and issues here for anything you suspect requires action in the source.
Contributions & Code of Conduct
The security policy and procedures can be found in
- Substrate Primitives (
sp-*), Frame (
frame-*) and the pallets (
pallets-*), binaries (
/bin) and all other utilities are licensed under Apache 2.0.
- Substrate Client (
sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
