About message signing(Yoroi Mobile)

Message signing allows you to cryptographically sign a message using your wallet address and later verify that signature. This is commonly used to prove address ownership without sending a transaction.

Which message formats are supported?

Yoroi supports signing and verifying the following message types:

• Plain text
• JSON
• Hexadecimal (hex)

Where can I find the Message Signing feature?

You can access it from the **Menu > Message signing **in the bottom navigation bar.

Note: Message Signing is currently not available on the Yoroi Browser Extension.

How do I sign a message?

1. Open the Sign tab.
2. Your wallet address is automatically displayed.
3. Enter any arbitrary message in the input field.
4. Tap Sign to generate a signature.

Once signed, you can copy:

• The signature

• The public key (pubkey)

How do I verify a message signature?

1. Open the Verify tab.
2. Paste the required elements (such as the message, signature, key, or pubkey).
3. Tap Verify to check if the signature is valid.

Yoroi will confirm whether the signature matches the provided message and address.
