Build Artifact

When a compilation succeeds, Remix creates a JSON file for each compiled contract. The JSON file contains the compilation's artifact.

Library Deployment

By default Remix automatically deploys needed libraries.

linkReferences contains a map representing libraries which depend on the current contract. Values are addresses of libraries used for linking the contract.

autoDeployLib defines if the libraries should be auto deployed by Remix or if the contract should be linked with libraries described in linkReferences

Note that Remix will resolve addresses corresponding to the current network. By default, a configuration key follow the form: <network_name>:<networkd_id>, but it is also possible to define <network_name> or <network_id> as keys.
