How to "Freeze" Your Zorb NFT

Learn how to transfer your Zorb without losing its color property!


In the 48 hours the Zorb NFT drop was active, over 53,000 zorbs were minted. Zorbs are colored orbs created by the Zora team - Zorbs are a long term branding and identity project. The main unique property of Zorbs is that the color of the Zorb depends on the wallet holding it. To explain more simply, a Zorb’s color is dependent on the wallet holding it - if you transfer your Zorb to someone else, the color WILL change.

Recently I had the chance to sit down with Iain, engineer at Zora, on a Twitch stream where we minted an NFT. During that stream, the topic of Zorbs came up and Iain shared a secret - you can actually ‘freeze’ Zorbs! He literally deployed the contract to enable Zorb freezing mid-stream - and we froze a Zorb. I am now in possession of the first ever Frozen Zorb!

There’s now a way to FREEZE your Zorb, so when you send it to someone else, the colors will not change. In this article, I will walk you through how exactly to freeze your Zorb!

From there, you can see all the Transfer Events that use Zorbs(ZORB) tokens, and the associated Token ID. That Token ID is what you will input into the final contact field.
