🔎 Signature Verification Tool
Did you receive a signed JSON file from Heavenkey?
This tool lets you verify the authenticity of the message using the EIP-712 signature standard.
✅ The tool checks:
the cryptographic signature validity
the Ethereum wallet that signed the message
the contents of the signed data (name, beneficiary, message, timestamp)
📄 No data is stored: the verification runs entirely in your browser.
This ensures the integrity and authenticity of the digital will, without using blockchain or centralized servers.
