Offline transaction signing

Offline transaction signing separates wallet key use from network access. The online wallet creates an unsigned transaction, the offline wallet signs it, and the online wallet broadcasts the signed result after verification.

Sign a transaction offline

  1. Prepare an offline wallet environment and a separate online wallet with verified software.
  2. Construct the unsigned transaction online and transfer only the unsigned transaction data.
  3. Sign the transaction on the offline wallet after reviewing the destination and amount.
  4. Transfer the signed transaction back using a clean, controlled method.
  5. Verify the signed data, then broadcast it from the online wallet and keep a record of the transaction ID.
