Unlink a Linked Permission

Overview

This guide explains how to remove a custom permission link from a smart contract action using the clio set action permission command with NULL.

Prerequisites

• Install the currently supported version of clio

info

| The clio tool is bundled with the Wire software. Installing Wire Core will also install the clio tool.

REMINDER

The install process has already set up the wallet for the root user. To interact with clio, ensure you are on the root user. Run sudo su - to switch to the root user.

• Understand the following:
  • What is an account
  • What is a permission level
  • What is an action
• You have previously linked a custom permission to an action (see Setting Custom Action Permissions)

Steps

To remove a linked permission level from an action, set the permission to NULL:

clio set action permission <account> <contract> <action> NULL -p <account>@active

Example

Remove the custom permission link from the hi action of the scontract1 contract for account bob:

clio set action permission bob scontract1 hi NULL -p bob@active

Example Output:

executed transaction: 7773ea2bcd5f335e842f4289094302faa06a8d4ff293bc1afaa9cdba0cdecb9a  120 bytes  234 us
#         sysio <= sysio::unlinkauth            {"account":"bob","code":"scontract1","type":"hi"}
warning: transaction executed locally, but may not be confirmed by the network yet         ]

Verify the change

clio get account bob

The permission links section should no longer show the scontract1::hi action:

permissions:
     owner     1:    1 SYS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
        active     1:    1 SYS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
           customp1     1:    1 SYS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
           customp2     1:    1 SYS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

permission links:
     customp2:
          scontract1::bye
     sysio.any:
