🖥️Pure Proxy

Pure proxies (used to be called anonymous proxies) are an advanced feature.

Pure proxies, in particular, can be used for permissionless management. In the example below, there is a multisig with four different accounts inside. Two of the accounts, Alice and Bob, have a pure proxy attached to them. In the case that the multisig account wanted to add or remove Alice or Bob or even add a new account into the pure proxy, the pure proxy would take care of that change.

If a multisig wants to modify itself without a pure proxy, a whole new multisig would need to be created.

Hence we strongly recommend everyone to setup proxy! Read how you can do that - Creating a pure proxy.
