Need to prove a wallet is yours? Sign a message instead of sending funds. You can also check anyone else's signature against the address they claim.

FAQs
Yes. We only ever ask you to sign a plain message, never a transaction. It proves you control the address and cannot move funds, approve spending or authorize anything.
No. Signing happens off-chain, so it never touches the blockchain. There's no gas to pay, and we don't charge for it either.
We check the address, message and signature together, character for character. A single extra space, a missing line break, or a message edited after signing is enough to break the match. The signature itself is usually fine.
No. We verify signatures entirely in your browser. There's no API call, no database and no RPC node involved. Open devtools and watch the network tab stay empty.
Never. Signing happens inside your own wallet. We only ever see the signature it produces, never your private key or recovery phrase.
