Can You Sign and Send Transactions Offline?
Overview: Is it possible to sign and send transactions while offline?
Key takeaway: Yes. Signing happens offline on the device, and you can export the signed transaction for broadcast from an online machine — what matters is keeping the private key on the device.
Points / steps:
- Prepare and verify the transaction data on a trusted device or network.
- Send the unsigned data to the Ledger device and sign offline.
- Export the signed transaction (no private key leaves the device).
- Broadcast the transaction from a trusted online device.
- Never type your recovery phrase into any software or website during this process.
Safety reminder: Make sure the broadcasting device is trusted. Avoid importing signed transactions on public machines — keeping the signing step fully offline is safest.
