WIth multi-signature, one account can be jointly controlled by multiple users. To execute an action initiated by one of the controlling users, the weighted sum of signatures by some or all users on the access list must reach a certain threshold.
Step 1: Open TRONSCAN, click “Sign in” on the top right. It is recommended that you login via TronLink.
Step 2: In the account page, scroll down to the module called “Multi-signature”.
There are three types of accesses available on TRONSCAN: owner access, active access and SR access. Owner access represents the supreme control over an account. Addresses with owner access can initiate any action that the account is entitled to;
Active access allows a combo of actions. For example, you may set up an active access to transfer TRX and freeze funds only. An address with active access of an account can only initiate actions allowed by its active access;
SR access is only available to SR accounts for setting up SR nodes. The following is an example of editing active access. Other accesses can be edited in the same way.
Step 3: Click “Edit Access” and name the active access in “Access Name” field.
Step 4: Click “Add” under “Operate” field. In the pop-up window, check boxes to add accesses or un-check boxes to delete them, then click “Save”.
Step 5: In “Threshold” field, set the threshold value representing the total weights required to execute an operation. It can be any integer equal to or larger than 1.
Step 6: In “Keys” field, enter the addresses you want to grant this active access to (5 addresses at most). Each address must be given a weight no larger than the threshold value, while total weights of all addresses combined must be larger than or equal to the threshold value. Transactions that require multi-signature are executed and recorded on the blockchain on the condition that addresses giving signed consent have a total weight greater than or equal to the threshold value.
Simply click “Add new accesses”, if you wish to add other new active accesses. A total of 8 active accesses are allowed.
Step 7: After editing, please click “Save” to save your changes.
