Over a year ago, I scanned a few nice numbers through an online web tool. Although I scanned them in offline mode, I was still afraid to use them, so I basically didn't use them much over this past year. Exporting and importing without mnemonic phrases is not convenient. Recently, I set up a multi-signature feature for my wallet, so now I can use it with peace of mind for receiving payments.
Tutorial:#
First, install a TronLink wallet, which can be found in the Google Chrome Web Store: Click here to install
Prepare 100 TRX in the wallet with the nice number that needs to be signed for as the fee for updating permissions.
Open the Tron browser: https://tronscan.org/#/wallet and connect it with the wallet.
Click on Permission Management
In the two input boxes I marked in the above image, enter the custom address of your other wallet. It must be an address using the TRC20 protocol!
The owner has ownership permissions, which are the highest permissions of the account. They can adjust the account's permission structure, perform all operations on the account, and act as the super administrator.
The active permission allows you to customize the account's permissions and add up to 8 active permissions, with each active permission able to add up to 5 addresses, acting as users.
The owner and active permissions can have different addresses. If you don't want the nice number wallet to have the ability to transfer funds, be sure to modify both. I forgot to modify the active permission, which cost me an extra 100 TRX (100 RMB) to make the changes.
