Ethereum NFT Security: Everything You Need to Know

By Sophia Young

There are around 30 billion transactions made in crypto every day. That number is growing exponentially, and that's the problem. Few protocols are available to complete a transaction quickly while maintaining privacy and security by using the blockchain, which can slow down transactions and increase costs.

One solution to this issue is Ethereum NFTs (non-fungible tokens), which can be used for making fast, secure decentralized exchanges between digital assets on the Ethereum blockchain.

What Are NFTs?

NFTs are a type of non-fungible assets that can represent various assets, such as shares in a company, virtual goods, and more. NFTs are kept on the Ethereum blockchain and may be generated and updated via a smart contract.

These tokens can be customized to meet the needs of each company's game or application. Once the token is uploaded to the blockchain, it cannot be changed without modifying the underlying code. NFTs are non-fungible because they can have different features and metadata. The uniqueness of NFTs makes them very special in that they can be used to represent anything that requires a digital identity.

How Are NFTs Used?

When NFTs are used in games, players can acquire virtual assets like a sword or treasure chest using tokens instead of purchasing them using fiat. These asset-backed tokens can then be sold to other players on the Ethereum blockchain later. In the case of assets with real-world value, NFTs can be used to represent assets.

For example, suppose you want to buy an item on Amazon. In that case, you will have to purchase that item using fiat currency. However, suppose you start an auction on eBay. In that case, potential sellers can send an NFT-based token to the buyer, which can then be exchanged for USD later.

Conversely, NFTs can also be used to represent real-world assets. In this case, a car owner could buy a token representing his vehicle and then use it as a platform to sell or trade the car without having to deal with the transaction fees and paperwork of selling the vehicle through a dealership.

How Secure Are NFTs?

Since each NFT token represents a specific asset type, the owner cannot use multiple tokens to represent a single unit of ownership. This can help to minimize fraud by discouraging the use of numerous identical tokens for the same asset.

The NFTs are, in effect, a software-generated tool for digitally recording and tracking assets. However, tampering with the NFTs would also mean that we can detect any changes made to the asset/token. Each token will have a unique identifier called an "address" that is stored on the Ethereum blockchain to address this. An NFT address can be used to track ownership of the token or alter it somehow.

To avoid tampering, the NFTs have a double token feature that prevents users from using the original NFT and another token for the same asset. The first token acts as an ownership record and is stored on the Ethereum blockchain. In contrast, the second token represents a tokenized version of that asset. Each time an asset is transferred, its actual ownership is recorded in the blockchain by a unique transaction hash along with its associated address.

How Are NFTs Transferred?

NFTs can be transferred through various means, including manual transactions or automatic smart contracts. Multiple transactions can be transferred in a single transaction, which minimizes transaction fees.

When using automated transactions, any token owner can create a smart contract that will digitally transfer ownership of the asset to another token owner.

What Are the Security Risks in NFTs?

There are various types of security risks associated with NFTs that have been discovered:

1. Monetary Incentives

Many of these tokenized assets can be used to issue a currency, which could create monetary incentives for hackers. Due to the lack of regulations, these currencies could be used by terrorists and other bad actors to circumvent financial regulations and launder money through their token networks.

2. Monetary Value

The monetary value in a token can also motivate crime. The black market for NFTs is the best example of this. The more expensive the NFT, the higher the interest in stealing it from its rightful owner.

3. Unauthorized Access

To protect against unauthorized access to these tokens, many companies put these on private networks with no real access to an outside network.

These security risks may impact these new digital assets in the future. Some projects have decided to remove NFTs from their platforms as they contend with security risks in these new initiatives.


NFTs are just beginning to be developed today, and they could become a crucial part of the future of digital gaming in the future. They have the potential to revolutionize digital gaming with more functionality and interactivity, which could lead to greater engagement between developers and players.

These new tokenized assets are also likely to attract more interest from investors and financial institutions. Thank you for reading this blog; if you're interested in more content like this, check out our blog now.
