How to sign a message with a Ledger device
How to sign a verification message with a Ledger device — approved physically on the device — to prove wallet ownership without moving any funds.
A Ledger can sign a verification message using keys that stay on the device — you approve the signature physically, on the Ledger's buttons. This proves ownership without moving funds.
How it works
- Begin the signing request in the connected app or flow (often via Ledger Live or a connected interface).
- Connect and unlock your Ledger and open the relevant asset app.
- The message to sign appears. Review it on the device screen and confirm it matches what you expect.
- Approve on the device to produce the signature, or reject if anything looks wrong.
Notes and limitations
- Message-signing support depends on the asset and app. Some Ledger apps support message signing; others don't. If signing isn't available for your asset, use a test transfer instead.
- The physical confirmation step is the security feature — nothing is signed without your button press on the device.
- Signing produces a signature only; it never moves funds.
