<aname="contributing-and-hacking"></a><h1class="show-anchors"><div>Contributing and Hacking<divclass="anchors"><aclass="self"href="/v5/contributing/#contributing-and-hacking"></a></div></div></h1><p>The ethers.js library is something that I've written out of necessity, and has grown somewhat organically over time.</p>
<p>Many things are the way they are for good (at the time, at least) reasons, but I always welcome criticism, and am completely willing to have my mind changed on things.</p>
<p>So, pull requests are always welcome, but please keep a few points in mind:</p>
<p><ul><li>Backwards-compatibility-breaking changes will not be accepted; they may be considered for the next major version </li><li>Security is important; adding dependencies require fairly convincing arguments as to why </li><li>The library aims to be lean, so keep an eye on the dist/ethers.min.js file size before and after your changes </li><li>Add test cases for both expected and unexpected input </li><li>Any new features need to be supported by me (future issues, documentation, testing, migration), so anything that is overly complicated or specific may not be accepted </li></ul></p>
<p>In general, <b>please start an issue <i>before</i> beginning a pull request</b>, so we can have a public discussion and figure out the best way to address to problem/feature. <b>:)</b></p>
