Currently, the "inspired by" label is only visible on OS1.
Just as traditional art is often inspired by the work of other artists, NFT collections may also be inspired by other popular collections.
We don’t permit copymints, but we do allow collections “inspired by” other popular collections if there are multiple, substantial changes in the work. These “inspired by” collections can help create ecosystems around popular collections, and the creators behind them aspire to build collections that take on a creative ecosystem of their own. Some of these collections have become notable in their own right and if they meet our requirements for collection badging, are now eligible to be badged.
As part of the badging review process, the OpenSea team will apply the "inspired by" label to these collections, which links to the original inspiration collection(s) to provide information for collectors who may be interested in understanding the project’s origins and inspirations.
