The abstract should be a short description of what the NEP will achieve.

Note that the — in the title is an elongated dash, not -.

Motivation and Scope

This section describes the need for the proposed change. It should describe the existing problem, who it affects, what it is trying to solve, and why. This section should explicitly address the scope of and key requirements for the proposed change.

Detailed description

This section should provide a detailed description of the proposed change. It should include examples of how the new functionality would be used, intended use-cases and pseudo-code illustrating its use.


This section lists the major steps required to implement the NEP. Where possible, it should be noted where one step is dependent on another, and which steps may be optionally omitted. Where it makes sense, each step should include a link to related pull requests as the implementation progresses.

Any pull requests or development branches containing work on this NEP should be linked to from here. (A NEP does not need to be implemented in a single pull request if it makes sense to implement it in discrete phases).

Backward compatibility

This section describes the ways in which the NEP breaks backward compatibility.


If there were any alternative solutions to solving the same problem, they should be discussed here, along with a justification for the chosen approach.


This section may just be a bullet list including links to any discussions regarding the NEP:

  • This includes links to mailing list threads or relevant GitHub issues.
