                    Sol-trace is a subprovider that needs to be prepended to your <a href="#">provider engine</a>.
                    Depending on your project setup, you will need to use a specific ArtifactAdapter. Sol-trace ships
                    with the <InlineCode>SolCompilerArtifactAdapter</InlineCode> for use with{' '}
                    <a href="#">Sol-compiler</a> and <InlineCode>TruffleArtifactAdapter</InlineCode> for use with the{' '}
                    <a href="#">Truffle framework</a>. You can also write your own and support any artifact format.
                </p>
