Is OpenSea Safe?

For the vast majority of people, OpenSea is an absolutely safe place to trade. Every dApp comes with the potential risk of vulnerabilities and fraudulent activity. That cannot be entirely avoided. However, as long you do proper research and trade diligently, you are unlikely to run into problems.

Is OpenSea safe? Yes, absolutely!

OpenSea is currently the largest NFT marketplace in the world.

Does that answer the question: Is OpenSea Safe? Not really.

While OpenSea mostly looks like every other website, it is actually a decentralized app (dApp) that is built on top of the Ethereum blockchain.

As with all software, dApps can also have vulnerabilities.

If scammers find a vulnerability, they can and will try to exploit it.

While this applies to every website on the internet, the difference is that the blockchain is censorship-resistant.

That means that once something has happened on the blockchain, it cannot be reversed without the agreement of both parties that were involved.

So if a scammer somehow manages to get a hold of one of your NFTs, no one will be able to retrieve it for you by force.

That is why the idea behind “self-custody” is so important.

Self-custody requires you to take the necessary measures to limit your exposure to risks because if something goes wrong, no one will be able to help you.

Despite recent reports of many people “losing” their valuable Bored Apes due to old active listings, most of these cases could have been prevented if the owners had taken better care of their NFTs.

So I’m not really sure I’d answer the question “Is OpenSea safe?” with a simple “No”.

OpenSea is certainly not without fault in this case, however, the owners must admit that they also messed up themselves.

So, is OpenSea safe to use?

Yes, for the most part, OpenSea is safe to use and the majority of users will never experience any theft.

Just make sure you’ve thought about purging all of your personal data from OpenSea.

Is OpenSea Legit?

Yes, OpenSea is a legitimate business. It is currently the dominant NFT marketplace and has the financial backing of many renowned investors, such as Adreessen Horrowitz, Mark Cuban, Tobi L├╝tke, Ashton Kutcher and many more.

Is OpenSea legit? Yes, it is.

The company was founded in 2017 by Devin Finzer and Alex Atallah and is headquartered in New York City.

After an initial pre-seed round led by Y Combinator in 2018, OpenSea has subsequently managed to get vast amounts of additional funding from various renowned investors, including a16z.

I’m pretty sure Marc Andreessen has a very strong opinion on the question “Is OpenSea safe?”.

OpenSea also recently acquired Ethereum wallet developer Dharma Labs in January 2022.

Despite all its success, OpenSea has also been at the center of a number of controversies.

In September 2021 its Head of Product was sacked for confirmed allegations of insider trading.

And in January 2022 OpenSea reimbursed multiples users a total of $1.8 million due to a software vulnerability that allowed scammers to buy extremely valuable NFTs at old and highly discounted, list prices.

Are There OpenSea Alternatives?

The most popular alternatives to OpenSea are LooksRare and Rarible. Especially LooksRare has attracted a lot of attention due to its LOOKS rewards token. More curated options for NFT art marketplaces are SuperRare and Foundation.

Despite all of the negative press that OpenSea has gotten in the past 6 months, it’s hard to refute that they must be doing something right.

The platform processes transactions in millions of dollars and for the most part, without any issues.

Is OpenSea safe? Sure, it’s no less safe than any of the other platforms.

As with every new unregulated market, scammers and fraudsters are likely going to try to exploit the lack of knowledge of users or technical vulnerabilities.

And as cynical as it may sound, this is part of the cost of doing business when you’re playing a risky game in the wild west.

That is why it is all the more crucial that you stay vigilant and always do your own research.
