Signed messages
Signing a message with an address proves you hold that address, without sending anything. Use Tools › Sign/verify message and pick the coin.
Signing
- Type the message. It can be several lines, or empty if you only want to prove ownership.
- Choose the address. For Monero, any of your subaddresses; for Bitcoin and Litecoin, any address of the selected wallet.
- Click Sign, then Copy to clipboard to copy the message, the address and the signature together.
Whoever checks it needs all three: the message, the address and the signature.
Verifying
Paste the message exactly as written (it is case-sensitive), the address and the signature, then click Verify.
- Monero signatures start with
SigV2.
- Bitcoin and Litecoin signatures use the format of Electrum, Sparrow and Bitcoin Core. Verifying works with any address type, legacy ones included.
