Stream Payments Nicknamer is a free Chrome add-on developed by dukewild. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. The add-on allows users to change their display name in Stream Payments.

The add-on is easy to use. Once installed, users can navigate to the Stream Payments "send" page for the desired recipient. On this page, a username will be listed next to the page title, along with an Edit button. Clicking the Edit button allows users to enter a new nickname. If an empty value is entered, the nickname will be reset to the default.

It's important to note that if major changes are made to the Stream Payments site, the add-on may break and revert to the default username. However, the likelihood of this happening is low.

Stream Payments Nicknamer is a convenient tool for users who want to personalize their display name when sending payments through Stream Payments.
