NFT sales and active wallets fell by more than 40% in the past month but new layer-2 infrastructure is preparing the sector for the next surge. Nonfungible tokens (NFTs) took the world by storm in March and April of this year with an onslaught of daily headlines about record-breaking sales and big-name companies dropping their own one-of-a-kind digital art pieces dominating the mainstream media.Fast forward a few months and the narrative has shifted to the 'NFT bubble' popping and doom and gloomers warning that NFT investors are on the verge of losing all of their money.NFT market 1-year history.

NFTs are down but not outAll is not lost, however, as there are many solid value propositions and use cases for NFTs that entrepreneurs and traditional businesses have noticed and embraced the sector.The blockchain ecosystem has already put forth multiple viable options to deal with problems facing the NFT sector, such as the launch of Enjin\u2019s\u00a0Efinity and JumpNet protocols which help to lower fees and allow for interoperability across different networks.Another popular solution Polygon, an Etheruem sidechain that allows projects to stay on Ethereum while also having access to a fast, low fee environment. In the past three months a large number of NFT-oriented and gaming projects have migrated to Polygon and as the crypto and NFT market improve, these low fee environments should help to boost activity on the network.Top 5 NFT marketplaces.
