The ENS Chain Letter is a unique NFT that is passed around between ENS name holders. It is visualized above: Each ENS name has a spot on the white circle and the colorful arcs represent the transfers between them.

The goal is to keep the streak going for as long as possible and make the picture look like a big ball of wool. If someone gives the token to you, it's on you to send it forward. Choose the next receiver wisely, we depend on you!

As a small incentive and token of appreciation for participating in this experiment, sending the letter automatically mints a "stamp": A custom NFT for the sender to keep.
