In an increasingly digital world, the need to manage and bequeath digital assets securely is more important than ever. Heavenkey is an innovative WordPress plugin that allows you to create and cryptographically sign a digital will directly from your website using a Web3 wallet. It leverages the power of EIP-712 signatures to provide tamper-proof proof of your intent, all while ensuring complete client-side privacy.
This tool is designed for simplicity and security. There is no coding required, and since everything happens in your browser, no sensitive data is ever stored on a server. Whether you're an individual wanting to leave a message for loved ones or a crypto holder with instructions for wallet distribution, Heavenkey provides a modern, secure method to make your digital wishes known.
How Heavenkey Works: A Step-by-Step Guide
Getting started with Heavenkey is straightforward. The plugin integrates seamlessly into your existing WordPress site.
- Install the Plugin: Upload the Heavenkey plugin folder to your WordPress site's
/wp-content/plugins/directory and activate it. - Add the Shortcode: Insert the simple
[heavenkey_form]shortcode into any post or page where you want the digital will form to appear. - Connect a Wallet: Your visitors connect their preferred Web3 wallet, such as MetaMask, Ledger, or any WalletConnect-compatible wallet.
- Enter Details: They fill in their name, the beneficiary's wallet address, and a personal message.
- Sign Securely: With a click of Sign with Wallet, the data is signed using a gas-less EIP-712 signature directly in the browser.
The result is a signed JSON file that contains the wallet address, a timestamp, the message, and the cryptographic signature. This file serves as verifiable, tamper-proof evidence of the user's intent.

Ensuring Security and Privacy
Heavenkey's architecture is designed to prioritize user security above all else. The entire signing process is executed client-side. This means private keys, seed phrases, and any other sensitive information never leave the user's browser and are never transmitted to a server or seen by the website owner. The plugin itself does not store any data.
Verifying Your Signed Digital Will
The integrity of the signed JSON file can be easily verified to confirm its authenticity.
- You can use the official browser-based verification tool available on the developer's website.
- The entire source code for the plugin and verification logic is open-source and available on GitHub for transparency and auditability.
The EIP-712 standard ensures that each signature is uniquely tied to the specific message and wallet, making it tamper-proof and verifiable by anyone with the correct tools. All verification is also performed client-side, requiring no backend services.
Frequently Asked Questions
How does Heavenkey handle my data?
Heavenkey operates 100% client-side. This means absolutely no data—including your message, beneficiary address, or signature—is stored on the website's server. Everything is processed and remains within your web browser.
Which cryptocurrency wallets are compatible?
The plugin supports any Web3 wallet that is compatible with the Ethereum Virtual Machine (EVM). This includes popular options like MetaMask, Ledger (via MetaMask or WalletConnect), WalletConnect v3, Trezor, Rabby, and Safe (formerly Gnosis Safe).
Is an EIP-712 signature legally binding?
An EIP-712 signature provides strong, cryptographically verifiable proof that a specific wallet address signed a specific message at a specific time. While this is powerful evidence of intent, its status as a legally binding document varies greatly by country and local jurisdiction. You should always consult a qualified legal professional for advice on enforceability.
Can I create multiple digital wills?
Yes, you can. Each time you use the form and sign a message, it generates a unique, standalone JSON file. You can create multiple signed declarations for different purposes or beneficiaries.
Is the plugin compatible with my WordPress theme?
Yes. Heavenkey is designed to be responsive and work seamlessly with all modern WordPress themes and major page builders, including the native Gutenberg editor, Elementor, and WPBakery.
How can I translate the plugin into another language?
The plugin is fully translation-ready and includes a .pot file template. You can use any standard WordPress translation plugin like Loco Translate, WPML, or Polylang to manage translations, or use a desktop tool like Poedit.
