They are lower-powered "siblings" of the ownership key, which has the sole power to transfer the assigned Urbit identity. Using Bridge, you can change the Ethereum addresses used for your proxies. If you use the Urbit HD wallet, your proxies have already been set.

                                                                                              There are three types of proxy.
