<p>Bitcoin-s also supports building native executables for various platforms supported by the <a href="https://www.graalvm.org/reference-manual/native-image/">graalvm native image</a> tool.</p>
<p>You can build by using the <a href="https://github.com/scalameta/sbt-native-image">native image plugin for sbt</a>. This will download the appropriate graalvm
version and the native image tool, and then build the cli</p>
<pre><code class="hljs css language-bashrc">sbt <span class="hljs-keyword">cli</span>/nativeImage

<p>After the build is done, you can find the artifact here locally</p>

</code></pre>
<p>We also publish native image binaries every time we merge a commit to master on github.
As an example, you can <a href="https://github.com/bitcoin-s/bitcoin-s/actions?query=workflow%3A%22Native+Image+bitcoin-s-cli%22">see the artifacts</a>
in the upper right hand corner.</p>
<p>If you don't want to build the <code>bitcoin-s-cli</code> yourself, you can download it for your platform there.</p>
