+Here is how to sign a transaction with an offline Electrum wallet.
+
+1. With your online (seedless) wallet, create the transaction using mktx:

+
+Electrum returns an unsigned transaction. Note that the serialization
+format contains the master public key needed and key derivation, used
+by the offline wallet to sign the transaction.
+
+
+2. Sign the transaction with your offline wallet: pass "hex" and "input_info" to 'signrawtransaction':
