Importing Source Files in Solidity

This tutorial will show you how to import local and external files.

The compilation result will also contain contracts implemented in the imported files.

For a detailed explanation of the import keyword see the Solidity documentation

Importing a local file

Other files in Remix can be imported just by specifying their path. Please use ./ for relative paths to increase portability.


Importing from GitHub

It is possible to import files directly from GitHub with URLs like<owner>/<repo>/<path to the file>.


Importing from Swarm

Files can be imported using all URLs supported by swarm. If you do not have a swarm node, will be used instead.
