Am I legally responsible for being a developer of a code, if my customer uses it illegally?
<p>I am from an Europe country, I work online and get orders on freelancer websites.</p>

<p>Few months ago, I had a customer hiring me to do some Bitcoin-related coding, I'm one of their developers for 6-7 months now.</p>

<p>I have already created 2 of their main projects (they have like 7-8). The code I wrote had nothing illegal in itself as far as I understand (basically I wrote a system in which users sign up for my customer's services, and get notifications, deposit addresses etc, and I delivered the source)</p>

<p>Today, I saw some very bad claims about them online, which I'm not sure if true or fake.</p>

<p>But I'm still really worried...</p>

<p>I have only received money for my programming, even lower than usual fee (because I needed the money).</p>

<p>My question is, am I responsible for what they do with my code?</p>

<p>I don't know anymore if their business is legit, should I stop working for them immediately? or I can continue if I'm not sure?</p>

<p>Am I already in trouble?</p>

<p><strong>P.S. I have generalized anxiety issue, and this constant stress doesn't let me sleep, so any help is really appreciated.</strong></p>

<p>As a baseline, you may assume that your code will be used legally. It sounds like this still applies in your case: there is an entirely reasonable and legal use for login code, so you had no reason to assume that there might be a problem. This puts you legally in the clear.</p>

<p>To be liable, you'd need to know or at least reasonably suspect that your code would be used to violate the law. </p>

<p>If you write code, and your employer uses it for illegal purposes, that in itself doesn't make you liable. </p>

<p>If you write software, and due to the nature of the software you knew or you should have known that it will be used for illegal purposes, that would likely make you liable. </p>
