OpenSea raises $2 million during their seed round (first real cash injection a startup receives)to make true digital ownership more accessible[4]. This was from the help of Y Combinator (YC), a technology startup accelerator company. Notable investors include: Coinbase Ventures, Founders Fund, and Chernin Group. Now with OpenSea, there is an option of exchanging digital collectibles between a third party that was originally done between two "untrusted" parties. Over the first few months, OpenSea had over half a million dollars in Ethereum a Cryptocurrency transferred through their smart contract.[5]
In June, OpenSea announces the ability to bid on NFTs. This allowed buyers and sellers a new option to obtain NFTs on OpenSea. OpenSea worked with a team at Wyvern protocol to create this new marketplace option.[6]
In July, they continued working with Wyvern protocol to build another feature, the allowed sellers to list their NFT's without paying gas. [7]

Ethical concerns
Insider Trading
Nathaniel Chastain, a former employee of OpenSea, was responsible for choosing which NFTs would be featured on OpenSea's homepage. Chastain used confidential information of NFT's that was soon to be featured on OpenSea homepage to purchase dozens of the NFTs before they were featured. This occurred for several months before the employee was caught and legally punished. According to the Department of Justice "CHASTAIN, 31, of New York, New York is charged with one count of wire fraud and one count of money laundering, each of which carries a maximum sentence of 20 years in prison."[21] "From at least in or about June 2021 to at least in or about September 2021, CHASTAIN used OpenSea’s confidential business information about what NFTs were going to be featured on its homepage to secretly purchase dozens of NFTs shortly before they were featured." [22]. Chastain was also forced to return any money that was made from these actions.[23] This leads to harmful actions against OpenSea users. [24]
Wash Trading
NFT Marketplace Competitors have little to no trading fees. Causing traders to buy and sell the same NFT repeatedly. This caused manipulation in the trading volume and analytics on OpenSea. [25]
Phishing Attack
Contract Vulnerability
OpenSea was subject to an exploit with the use of Wyvern Protocol, used for most NFT smart contracts. "One explanation (linked by CEO Devin Finzer on Twitter) described the attack in two parts: first, targets signed a partial contract, with a general authorization and large portions left blank. With the signature in place, attackers completed the contract with a call to their own contract, which transferred ownership of the NFTs without payment. In essence, targets of the attack had signed a blank check — and once it was signed, attackers filled in the rest of the check to take their holdings." [26]
OpenSea users move there nfts from one wallet to another for many reasons. The discovery of not desired feature linked to it. If users had an NFT listed on a wallet which they transfered, the new wallet would now have this NFT and with no listing shown to the NFT. If a user was to send the NFT back to the wallet it was listed on, the listing would show back up and allow buyers to purchase. This caused many users to be harmfully affected by this unknown fact. Many collectors of the Bored Ape Yacht Club NFT lost large amounts of money due to this. As the price of an NFT collection raises, users who transferred their NFT to an old wallet where it was listed would soon realize there NFT was purchased under the current value within seconds by bots for such events. [27]
Email Scam
Some OpenSea users reported Wednesday receiving emails from “team@opensea.io”. According to @0xQuit on Twitter, the phishing link redirects users to a scam site that attempts to steal their seed phrase. [28] " A seed phrase is a master key that unlocks access to all your crypto assets. It’s like giving someone your bank account username and password." [29]
