# also private keys

How can I properly use importmulti and put all my keys there?

Any answer would be appreciated.

Answer 1

Here's a basic example of how you can use importmulti:

bitcoin-cli importmulti '[{"scriptPubKey": {"address": "13LJXzFwARH5N2bR1AV38Nf9qDVw53PjiB"}, "timestamp":0}]'

In this example, we are importing a single address. You can extend this to include all your addresses. However, keep in mind that using importmulti with private keys directly in the command line is not secure, as it may expose your private keys to other users on your system.

Here is an example with multiple addresses and their corresponding private keys:

bitcoin-cli importmulti '[{"scriptPubKey": {"address": "13LJXzFwARH5N2bR1AV38Nf9qDVw53PjiB"}, "timestamp":0},{"scriptPubKey": {"address": "1BcBMuEJJzEY36PmKWTFmYRxEF3YaSEiKN"}, "timestamp":0},{"scriptPubKey": {"address": "1NeZCnuSW9NG8F147VNf8JSLKWGcVexZ32"}, "timestamp":0}]' '[{"keys": ["private_key_1", "private_key_2", "private_key_3"], "timestamp":0}]' '{"rescan": false}'

Make sure to replace "private_key_1", etc., with your actual private keys.

it's crucial to handle private keys securely. Storing them in plaintext in commands or scripts is not recommended.
