What is Permit2? - Contract Guide + How to Revoke
A smart contract originally conceived by Uniswap, Permit2 manages the approval of token transfers via gasless signatures.
Investors and crypto enthusiasts are always searching for the most secure solutions to manage their digital assets. In the wake of the FTX debacle of 2022, more than ever users are turning towards self-custody solutions that minimize reliance on trusted third parties.
On that front, DeFi wallets are in high demand and Rabby Wallet is an option that’s quickly gaining mindshare. But the fact of the matter is, Rabby is only one in a sea of wallet providers. Users must carefully weigh their options to know whether or not it’s the right choice. And the most important question they ask boils down to “Is Rabby Wallet Safe?”.
Today, we’ll answer this question and also cover the features that make Rabby such a popular wallet for DeFi power users.
The answer? Yes. Rabby Wallet was developed by DeBank, a known and trusted entity in the DeFi space. It is also an open-source project, which is a significant marker of transparency and security. You can view the Rabby GitHub here.
The Rabby Wallet homepage touts a commitment to security
Open-source software allows the community and security experts to review the code continuously, ensuring there are no hidden malicious functions or vulnerabilities. The fact that Rabby Wallet’s code and history of audits are available online is a clear indication of its legitimacy and security. These audits are performed by reputable firms and are available for public review, providing reassurance about the wallet’s security measures.
But what about the underlying product itself? How secure is Rabby Wallet?
Because it is a non-custodial wallet, the Rabby team (or DeBank) does not have any access to user funds. This means that you have full ownership over your digital assets.
This is a double-edged sword, however, because it also means the responsibility for security largely falls on the user. Keeping your seed phrase secure and your devices with Rabby Wallet installed free from malware is crucial.
Rabby Wallet’s security features are more or less on par with industry standards, with a set of functions aimed at protecting users as they make transactions on the blockchain. The wallet offers pre-transaction risk scanning and transaction previews, which show potential balance changes before you confirm a transaction. This can alert users to unexpected changes or fees, enhancing safety against hidden risks in smart contracts.
Rabby transaction simulations are clear and concise
The ‘How safe is Rabby Wallet’ question often concerns users unfamiliar with the differences between wallets and exchanges. Unlike centralized exchanges, Rabby does not hold your assets, thus eliminating a central point of failure. Security features such as transaction simulations and security alerts further protect users by providing real-time feedback on transaction safety and potential phishing attacks.
In addition, Rabby’s focus on safety extends to its integration with hardware wallets, offering an added layer of security for users who want to ensure their private keys are never exposed online.
It’s clear that Rabby is a safe DeFi wallet option. But even though this is the case, we also need to consider: Is Rabby a Good Wallet? Let’s review the features offered by Rabby to better understand how it stands among the plethora of wallet choices available out there.
Rabby Wallet truly shines when considering the amount of chains and assets that are supported. Just like similar competitors like MetaMask or Trust Wallet, Rabby is compatible with all Ethereum Virtual Machine (EVM) chains.
Just a portion of Rabby’s available networks
This includes popular networks like Ethereum, Polygon, Arbitrum, and Optimism. Because of this, the wallet’s token support extends to over 10,000 cryptocurrencies, making Rabby Wallet an ideal choice for users looking to manage a diverse portfolio of digital assets.
Rabby Wallet has a fantastic in-built token-swapping capability. Users can easily trade tokens directly within the wallet, connecting to multiple decentralized and even some centralized exchanges to ensure the best possible rates.
The Rabby swap interface
This feature is not only convenient but also enhances the user’s control over their trading activities, bypassing the need to interact with potentially unsafe external platforms.
Hardware wallet support is a must for anyone who is serious about DeFi security. For those who want to use their hardware wallets, Rabby Wallet offers integration with popular hardware wallet options like Ledger and Trezor.
The reason for this is to allow users to store private keys offline while still enjoying the wallet’s comprehensive features. Hardware wallets are well-known for providing an extra layer of security, making Rabby Wallet a robust choice for serious investors.
One of the most user-friendly aspects of Rabby Wallet is its approach to fees – there are no additional fees charged by the wallet for transactions. Users only need to cover the network fees as they would expect and these are dictated by the on-chain conditions. However, it is important to note that Rabby DOES charge a .25% fee on swaps completed within the wallet.
Multiple accounts are a necessity for anyone serious about DeFi. Rabby Wallet does not leave this out – it supports the creation and management of multiple accounts within the same wallet.
Managing wallet addresses in Rabby
This feature is particularly useful for users who wish to separate their personal, trading, and investment crypto holdings, or for those managing crypto assets on behalf of others.
The above is all good for people who like to hold and trade tokens in DeFi. But as NFTs continue to grow in popularity as an asset class, having a secure place to store them has been another thing that users look for and one more item that Rabby Wallet does well.

Rabby provides wide-ranging support for NFTs allowing users to view, manage, and transfer NFTs just as easily as cryptocurrencies.
Although Rabby was initially released as a browser extension, it doesn’t end there. The wallet also provides desktop applications for both Mac and Windows which offer all functionalities accessible in its browser extension within a self-contained desktop setting (some might see this setup as being safer).
Additionally, Rabby is in the middle of beta-testing a mobile application that will offer the full features of Rabby Wallet on iOS and Android devices. This development, specifically for users who like managing their crypto while traveling or away from home, is quite promising.
If you have read to this point, you are probably thinking that Rabby Wallet is quite safe indeed. However, no matter how safe an underlying wallet is, your digital assets are always at risk of being stolen in a moment of user error. Please take note of the measures below to ensure that your funds never fall into the wrong hands.
How you deal with your seed phrase is very important when using Rabby Wallet or any other blockchain wallet. No other security measure will save you if your seed phrase is leaked either by mistake or otherwise. The seed phrase usually consists of 12 to 24 words and it’s a sequence that gives access to your funds.
You need to keep this phrase in a safe place that is not connected online. Putting it on paper and keeping it in a private location or using high-tech methods like a metal seed storage device, which is both fireproof and waterproof, is a best practice.
This will help you avoid losing the phrase because of problems with your computer or physical damage to items such as floods or fires. Never keep your seed phrase in digital format (for example, taking a photo of it on your phone’s screen, saving it in a cloud storage service, or sending it via email). Doing so could leave your funds easily accessible to malicious hackers.
The security setting of the device you use for accessing Rabby Wallet is very important for protecting your money. Make sure this device doesn’t have any malware or viruses on it by using good antivirus software and keeping everything updated. Put firewall protections up and avoid installing unnecessary apps that could harm the integrity of your system.
Frequently updating your operating system and browsers is also key because this helps patch weaknesses that bad actors can use.
A quick scroll of Crypto Twitter/X will reveal an endless list of fake phishing websites, vying to steal your funds. With that in mind, make sure you check if websites are real before you even start clicking on and interacting with them.

Rabby Wallet can help in this aspect of safety somewhat, but it’s still necessary for you to make sure that you don’t visit phishing sites that copy real platforms. Take advantage of web security extensions, which help in blocking malicious websites and carefully examine URLs for any strange characters or misspellings. You may also want to bookmark frequently used pages so you avoid typos in URLs which could inadvertently lead you to a phishing site. Finally, Participate in community forums and read trusted security blogs to keep updated with the latest threats and suspicious sites.
Before you proceed to engage with smart contracts via Rabby Wallet, it is recommended that you first use the De.Fi Scanner for auditing these contracts. This tool is an all-in-one automated smart contract auditor that allows you to examine any contract or token, simply by entering its address in a search bar.

Scanner can identify common vulnerabilities as well as suspicious functions. It does so by checking what actions a contract will perform with your wallet, making sure it doesn’t have any code that might result in unauthorized transactions or losses. Such audits, especially for lesser-known or fresh tokens in the DeFi area, can be extremely important.
It’s very important that you keep an eye on the permissions given to various dapps through Rabby Wallet. You can use the De.Fi Shield to manage and review these permissions properly. With this tool, you can easily find out which dapps have the ability to access your funds and in what situations.

When a dapp stops needing access, or if you stop using the service, take away the permissions to lower the risk of unintended transactions. Checking and adjusting your permissions regularly helps in reducing possible exposure to harmful actors or faulty contracts.
Investing a good deal of money in crypto? It may be time to start seriously thinking about combining a hardware wallet with Rabby Wallet for better security. A hardware wallet keeps your private keys offline, giving extra protection by separating them from devices connected to the internet.
With Rabby Wallet, you can start transactions that are signed in the safe area of a hardware wallet. This ensures no exposure of private keys into online environments, or even in a browser file which may not be secure. This is a good practice for people who have large amounts of assets or do many transactions. It reassures them that their wealth will remain safe, even if their computer gets attacked.
Understanding the differences between Rabby Wallet and cryptocurrency exchanges is critical for users to effectively manage their digital assets. The basic difference between them comes from their operational characteristics; Rabby Wallet is an open-source web3 wallet, whereas cryptocurrency exchanges are centralized platforms.
Rabby’s main dashboard makes it easy to explore web3
Rabby Wallet is a browser add-on that enables direct interaction with blockchain networks. It allows users to store, send, and receive cryptocurrencies without an intermediary. Being non-custodial, Rabby Wallet gives users complete control over their private keys and, consequently, their funds – this aspect underscores a major security advantage as control isn’t relinquished to a third party. Moreover, Rabby Wallet supports interaction with various decentralized applications (dapps) and protocols directly, facilitating earlier access to new tokens and DeFi projects compared to most exchanges.
Crypto exchanges, on the other hand, are centralized platforms where users can buy, sell, or trade cryptocurrencies – these platforms hold all your funds, meaning your private keys are managed by the exchange. On the one hand, this setup can offer a more user-friendly experience, especially for beginners, and provides some level of recovery options if login credentials are lost. However, it also introduces risks such as potential exposure to exchange hacks, operational failures, or regulatory actions that could affect access to your funds – one needs to look no further than the cautionary tales found in our De.Fi REKT Database.
At the end of the day, the choice between Rabby Wallet and a crypto exchange depends on your priorities, whether it’s having full control over your assets or preferring the convenience, deep liquidity, and additional services that exchanges may offer.
