The increased interest in non-fungible tokens are driving the flow of cryptos to two types of ethereum (ETH-USD) smart contracts linked to NFT marketplaces from the onset of 2021 through mid-December, according a report from Chainalysis. Users sent $40.9B worth of crypto to ERC-721 and ERC-1155 contracts - revised from just $26.9B in a December report that was based on data through mid-October. Recall NFT marketplace OpenSea recently raised $300M in a Series C funding round, valuing the company at $13.3B - making it a big player in the space. NFT-related stocks are mixed so far on Thursday, including: Vinco Ventures (BBIG +1.1%), Liquid Media Group (YVR), WISeKey International (WKEY -0.2%), Dolphin Entertainment (DLPN +0.6%), Color Star Technology (CSCW +0.8%) and Humbl (OTCPK:HMBL -1.5%).
