                        Sol-profiler gathers line-by-line gas usage for any transaction submitted through your provider.
                        This will help you find unexpected inefficiencies in parts of your smart contract, and take a
                        data-driven approach to optimizing it.

                        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.
