Sign and secure your digital will using Web3 wallets. EIP-712 signature, no server storage, 100% client-side privacy.
Heavenkey is the first WordPress plugin that allows users to write and off-chain sign a digital will — directly from your website, no coding required.
How it works
- Add the
[heavenkey_form]shortcode to any page or post. - Visitors connect their Web3 wallet (MetaMask, Ledger, WalletConnect, etc.).
- They enter their name, a beneficiary wallet address, and a personal message.
- Clicking Sign with Wallet signs the data using EIP-712 (gas-less) directly in the browser.
- The result is a tamper-proof signed JSON including wallet address, timestamp, message, and signature.
Key features:
* 100% client-side – no server storage.
* Privacy by design – all data stays in the browser.
* Secure by default – EIP-712 signature for proof of authorship.
* Translation-ready – .pot template included.
* Theme-compatible – works with any theme or builder.
* Blockchain-neutral – supports Ethereum, Polygon, Arbitrum, BNB, Base, and other EVM chains.
Disclaimer: Heavenkey is not a legal replacement for an official notarial will. It provides cryptographic proof of intent. Consult local regulations for legal validity.
Who Can Use Heavenkey?
- 👨👩👧👦 Private individuals & families – create a personal digital will or message for loved ones.
- 🧑⚖️ Lawyers & legal-tech consultants – offer a digital pre-declaration tool to clients.
- 🎨 Artists & creators – sign a statement regarding future use of their work or profiles.
- 🏛️ DAO members & multisig signers – publish exit intents or succession signals.
- 🪙 Crypto holders & DeFi users – leave instructions about wallets or fund distribution.
- 💼 Start-ups & fintech founders – time-proof signed intents (e.g. on IPFS).
Security & Privacy
All signing occurs entirely in the user’s browser. No private key, seed phrase, or sensitive data is stored or transmitted.
Signature Verification
Signed JSON files can be verified using:
