The security problems of NFTs: solutions

23 January 2023

Non-Fungible Tokens (NFTs) have been gaining popularity in recent years, with many people buying, selling, and collecting these digital assets. However, as the market for NFTs grows, so does the concern for their security. Specifically, many people who use MetaMask, a popular digital wallet for storing and managing NFTs (and to authenticate in many platforms), have raised concerns about the security of their NFTs within the wallet.

In fact, Metamask has begun to provide very clear alerts during some operations, suggesting that if you want to sell an NFT that is inside your wallet, when this happens with an attacker, he can steal all the NFTs in your wallet. If you are interested in selling your NFTs, you run many risks, precisely due to a problem of vulnerability of the smart contract.

All of this also suggests that many investors are choosing to keep NFTs in their wallet rather than sell them

Wallet Security

One major concern is that MetaMask is a hot wallet, meaning that it is connected to the internet and can be vulnerable to hacking attempts. While MetaMask has implemented various security features such as seed phrase backups and two-factor authentication, some users have reported losing access to their wallets or having their NFTs stolen due to a lack of proper security measures. Another concern is that MetaMask does not currently offer a way to insure NFTs, which means that if a user's NFTs are stolen or lost, there is no way to recover them. This lack of insurance options can make many potential NFT buyers and holders hesitant to use MetaMask as their primary wallet. It's important to mention that, the problem is not specific to MetaMask, but to the current state of the NFT market, as many other wallets and platforms also face similar security issues.

To mitigate these concerns, users can take several steps to secure their NFTs. One important step is to ensure that their MetaMask wallet is properly secured, including using a strong password, enabling two-factor authentication, and regularly backing up their seed phrase. Additionally, users should be cautious when buying NFTs from untrusted sources and should always verify the authenticity of an NFT before purchasing it.

In conclusion, while MetaMask is a popular and convenient option for managing NFTs, the security of NFTs within the wallet remains a concern for many users. It's important for both the wallet providers and the users to be aware of these security issues and take the necessary steps to protect their NFTs.


Concrete and satisfactory solutions have not yet been found, there is reason to think that the largest banks are inserting themselves into web 3.0 among the various objectives also to become the guarantors and/or be the solution to the problem
