<p>Sign and secure your digital will using Web3 wallets. EIP-712 signature, no server storage, 100% client-side privacy.</p>
<p><strong>Heavenkey</strong> is the first WordPress plugin that allows users to write and off-chain sign a digital will — directly from your website, no coding required.</p>
<h3>How it works</h3>
<ol>
<li>Add the <code>[heavenkey_form]</code> shortcode to any page or post.  </li>
<li>Visitors connect their Web3 wallet (MetaMask, Ledger, WalletConnect, etc.).  </li>
<li>They enter their name, a beneficiary wallet address, and a personal message.  </li>
<li>Clicking <strong>Sign with Wallet</strong> signs the data using EIP-712 (gas-less) directly in the browser.  </li>
<li>The result is a tamper-proof signed JSON including wallet address, timestamp, message, and signature.</li>
</ol>
<p>Key features:<br />
* <strong>100% client-side</strong> – no server storage.<br />
* <strong>Privacy by design</strong> – all data stays in the browser.<br />
* <strong>Secure by default</strong> – EIP-712 signature for proof of authorship.<br />
* <strong>Translation-ready</strong> – <code>.pot</code> template included.<br />
* <strong>Theme-compatible</strong> – works with any theme or builder.<br />
* <strong>Blockchain-neutral</strong> – supports Ethereum, Polygon, Arbitrum, BNB, Base, and other EVM chains.</p>
