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.

<p>
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>
<Tabs>
<TabBlock title="Sol-compiler">
<Code language="javascript">
{`import { SolCompilerArtifactAdapter } from '@0x/sol-trace';
// Both artifactsDir and contractsDir are optional and will be fetched from compiler.json if not passed in
const artifactAdapter = new SolCompilerArtifactAdapter(artifactsDir, contractsDir);`}
</Code>
</TabBlock>
<TabBlock title="Truffle">
<Code language="javascript">
{`import { TruffleArtifactAdapter } from '@0x/sol-trace';
const projectRoot = '.';
const solcVersion = '0.4.24';
const artifactAdapter = new TruffleArtifactAdapter(projectRoot, solcVersion);`}
</Code>

<Code language="javascript">
{`import { AbstractArtifactAdapter } from '@0x/sol-trace';
class YourCustomArtifactsAdapter extends AbstractArtifactAdapter {...};
const artifactAdapter = new YourCustomArtifactsAdapter(...);`}
</Code>
</TabBlock>
</Tabs>
<p>
Now that we have an <InlineCode>artifactAdapter</InlineCode>, we can create a{' '}
<InlineCode>RevertTraceSubprovider</InlineCode> and append it to our provider engine.

<Code language="javascript">

const providerEngine = new ProviderEngine();
providerEngine.addProvider(revertTraceSubprovider);
