  <h1>Support via Crypto</h1>
  <p>If my open-source computer vision and edge AI work has helped you, you can support it directly with cryptocurrency. Select the token below to reveal the matching wallet address.</p>

<div class="crypto-warnings">
  <div class="warn-box warning">
    <span class="warn-icon">&#9888;&#65039;</span>
    <div><b>Warning — transfers are irreversible</b>
    Crypto transactions cannot be reversed, refunded, or recovered once confirmed. There is no chargeback and no support line that can undo a transfer. Double-check everything before you send.</div>
  </div>
  <div class="warn-box caution">
    <span class="warn-icon">&#9888;&#65039;</span>
    <div><b>Caution — send on the correct network</b>
    Ethereum, Base and BNB Smart Chain share the same address (<code>0xFcE7&hellip;53B0C</code>). Sending on the wrong network — for example Base instead of Ethereum — can permanently lose your funds. Always verify the network in your wallet before confirming.</div>
  </div>
  <div class="warn-box note">
    <span class="warn-icon">&#8505;&#65039;</span>
    <div><b>Note — voluntary, no invoice</b>
    This page is a voluntary support option, not a purchase or invoice. Crypto payments are final with no automatic receipt or confirmation. If you are unsure, send a small test amount first.</div>
  </div>
  <div class="warn-box when">
    <span class="warn-icon">&#128161;</span>
    <div><b>When to use it</b>
    Use crypto to support the work anonymously or internationally with low fees. For contracts, invoices, consulting, or anything that needs a receipt, email <code>info@pirahansiah.com</code> instead.</div>
