All About Wallet Approvals: Your Path to Safer Crypto Transactions

As we venture deeper into the realm of blockchain technology and cryptocurrency, the web3 space presents both revolutionary opportunities and complex challenges. Two fundamental elements of this environment are asset approvals and wallet security. Given a recent surge in malicious attacks, understanding and managing wallet approvals has become essential for crypto enthusiasts. 

Wallet approvals are partially akin to giving a valet the responsibility to park your car; you're trusting someone else to handle your valuable assets. The launch of Webacy's Approval Management product is an important moment in wallet security, addressing the critical need for users to discern, keep track of, and manage their wallet's approvals. Let's dive into the ecosystem of approvals, sorting the safe from the suspect, and explore how Webacy provides the tools to maintain approval hygiene.

What Are Wallet Approvals?

Wallet approvals are permissions that crypto holders grant to smart contracts, enabling them to access and execute transactions with digital assets on their behalf. This delegation is a core functionality in web3, allowing users to transact on decentralized platforms, list assets on marketplaces, or participate in various DeFi protocols without constant manual authorization.

The Two Types of Approvals

There are generally two main kinds of approvals that stem into different iterations, but they follow these two forms: 

Set Approval for All (SAFA): This type of approval empowers a smart contract to interact with all assets of a particular type or collection within your wallet. It could apply to an entire NFT collection, encompassing standards like ERC-1155, ERC-721, or ERC-721a. SAFA might seem risky at a glance, mainly due to its broad authority; however, it's not inherently dangerous. When used with reputable platforms, it simplifies transactions, allowing for a seamless market experience. The crucial aspect is the trust placed in the approved entity.

Individual Approval: In contrast to SAFA, individual approvals limit permission to a single asset or action. This could be approving a single NFT for sale on a marketplace or authorizing a specific amount of ERC-20 tokens like Apecoin for use within a protocol. This narrow focus mitigates risk by limiting access to your assets, making it the more cautious option for maintaining control over your digital valuables.

Here it is critical to stress that the issue doesn't lie with the approvals themselves, but rather with their misuse by ill-intended parties. Trustworthy platforms and services utilize these approvals to ensure users can enjoy the web3 space's benefits. The challenge for users is to stay vigilant, authenticate sources, and track their approvals to prevent abuse.

Recognizing the Risks

While these approvals enable a wealth of functionalities within the cryptocurrency ecosystem, they also come with potential security concerns that must not be overlooked.

Phishing Scams: Phishing remains a significant threat in the crypto space. Users may be tricked into granting approvals to malicious smart contracts via fake websites that mimic legitimate platforms. Once permissions are in place, scammers can drain tokens or NFTs from the victim's wallet.

Unnecessary Broad Approvals: SAFA approvals, in particular, can be risky if provided unnecessarily. For instance, granting blanket approvals to a contract when you only need to authorize a single action (e.g., selling one particular NFT) gives potentially malicious contracts more access than required.

Outdated Approvals: Approvals for discontinued projects or platforms that you no longer use can still be active. These forgotten permissions might become a backdoor for attackers if the dormant smart contracts become compromised in the future.

Signature-Based Attacks: Some malicious actors create schemes that trick users into signing transactions that look harmless but, in effect, use the user's existing legitimate approvals to transfer assets without direct authorization. In this case, one's approval might not be at fault, but their signature can be misused to execute a transaction, sometimes to a spoofed destination wallet.

Fake NFT Drops: Scammers often advertise fraudulent NFT drops that bait users into interacting with a smart contract under the guise of receiving free or exclusive digital assets. These deceptive schemes are typically designed to prompt the user to grant substantial approvals. Once the user has given permission, scammers can access the user's assets without further consent.

Deceptive Trading Sites: Another common risk arises from fake trading platforms mimicking authentic marketplaces. Users may unknowingly give SAFA approvals to these platforms, believing they are setting up for a legitimate trade. Scammers behind these sites can then use the approvals to transfer out all applicable assets from the user's wallet without any additional confirmation or transaction from the user.
