Sign & verify a message
Prove you own a wallet by signing plain text, or check whether a signature is genuine.
Wallet required
Sign a message with your connected wallet. Anyone can then confirm the signature came from your address — without you ever sharing your private key. This is the personal-message standard.
Any text — a login challenge, a proof phrase, whatever the app asked you to sign.
No signature yet
Sign a message on the left and it appears here, ready to share.
