Nonfungible token (NFT) marketplace OpenSea is once again listing the Polygon-based copy of CryptoPunks after a successful Digital Millennium Copyright Act counter-notice.  In a Tuesday announcement on Twitter, the PolygonPunks project said its NFT collectibles were back on OpenSea after responding to a DMCA takedown notice from Larva Labs, the creator of CryptoPunks. The punks were booted from OpenSea in August after becoming one of the most popular collections on the marketplace. PolygonPunks ARE BACK ON @Opensea!!! The DMCA counter notice to Larva Labs was successful We have resumed trading on the largest NFT marketplace in the world We look forward to building a relationship with @0xPolygon and it's ecosystem as we grow on the Polygon network. pic.twitter.com/3qk6rK8BX8
