OpenSea
OpenSea is an American non-fungible token (NFT) marketplace headquartered in New York City. The company was founded by Devin Finzer and Alex Atallah in 2017. OpenSea offers a marketplace online allowing for non-fungible tokens to be sold directly at a fixed price, or through an auction. History Devin Finzer and Alex Atallah founded OpenSea in December 2017. They were inspired by CryptoKitties, a blockchain-based game featuring non-fungible tokens that had been released earlier that year. Finzer and Atallah believed that OpenSea could be a marketplace for buying NFT tokens like those at scale. They entered Y Combinator's accelerator program in 2018, where OpenSea was described as a "peer-to-peer marketplace for cryptogoods". After a 2018 pre-seed round by Y Combinator, OpenSea raised $2.1 million in venture capital in November 2019. In March 2021, the company raised $23 million in venture capital; four months later the company announced another investment round of $100 million making it a unicorn. In March 2020, the platform had 4,000 active users completing $1.1 million in transactions a month. By July 2021, users were completing $350 million in transactions a month, and the company was valued at $1.5 billion after a $100 million Series B venture round led by Andreessen Horowitz. In August 2021, the value of monthly transactions spiked to $3.4 billion, and in November OpenSea had 1.8 million active users. In September 2021, OpenSea admitted that an employee engaged in insider trading. OpenSea's Head of Product hoarded NFTs just before they were featured on the homepage. In January 2022, the company had been valued at $13.3 billion and was described as the largest non-fungible token marketplace. The daily trading volume on the OpenSea marketplace reached $2.7 billion on May 1, 2022, but four months later had dropped by 99%. In January 2022, OpenSea acquired Ethereum wallet-maker Dharma Labs. Later that month, OpenSea reimbursed users about $1.8 million after a user interface bug allowed users to buy more than $1 million worth of NFTs at a discount. On January 27, 2022, OpenSea announced it would limit how many NFTs a user can create using the free minting tool. The following day, OpenSea reversed the decision following user backlash and later admitted that 80% of NFTs created with the tool were plagiarism or spam. On February 19, 2022, some users began to report that some of their NFTs disappeared. OpenSea later revealed a phishing attack had taken place on its platform via an exploit in the Wyvern Platform. The company denied rumors the source of the theft was its website, its listing systems, emails from the company, or an upgraded contract system. The next day, The Verge reported that hundreds of NFTs were stolen from OpenSea users causing a huge panic among the platform community. The estimated value of the stolen tokens is more than $1.7 million. According to OpenSea, only 32 users had been affected. OpenSea later revised its statement to note that 17 users were directly affected, while the other 15 users had interacted with
