What Is Rabby Wallet?
Rabby Wallet is a self-custodial crypto wallet designed primarily for Ethereum and other EVM-compatible blockchains. It’s developed by the same team behind DeBank, a well-known DeFi analytics and portfolio tracking platform. Rabby Tokens+2Rabby+2
As a self-custodial wallet, Rabby gives users full control of their private keys. In other words, Rabby does not store your keys or custody your funds – you do. Rabby Wallet+1
Rabby is available as a browser extension, which supports a wide range of EVM chains. Rabby+2Rabby+2
Core Features of Rabby Wallet
Rabby’s design and feature set are closely aligned with the needs of DeFi users, especially those who frequently interact with decentralized applications (dApps), smart contracts, and perform cross-chain operations. Here are its major features:
Automatic Chain Switching
Rabby detects which blockchain a dApp is running on and automatically switches your wallet’s network accordingly. Rabby+1
This removes the friction and risk associated with manually switching networks (for example, switching from Ethereum Mainnet to Polygon or Arbitrum). Rabby Teachable+1
Transaction Simulation / Preview
Before you sign a transaction, Rabby simulates it and shows a detailed preview. This includes how token balances will change, gas costs, and other effects. Rabby FAQ+2Rabby+2
This is very useful to avoid mistakes, malicious contracts, or unintended approvals. Metana
Built-in Risk Analysis / Security Engine
Rabby has a risk-scanning mechanism that checks for potentially malicious contracts or risky token approvals. Rabby+2Rabby FAQ+2
For instance, if a contract asks for unlimited token allowance (approval), Rabby can warn the user. secure-rabby-en-faq.teachable.com+1
It also shows “balance change preview” so you can see what tokens will leave or come into your wallet. Rabby Wallet
Risky Approval Alerts + Batch Revoke
Rabby alerts you when you've approved potentially dangerous or malicious contracts. Rabby Wallet+1
It provides a batch-revoke feature, letting you revoke multiple approvals at once — saving time and reducing risk. Rabby Wallet
Whitelist Feature
You can mark certain addresses as “trusted” (whitelisted). For non-whitelisted addresses, Rabby asks for extra confirmation (e.g., password) before sending — offering an extra layer of security. Rabby Wallet
However, this doesn’t stop someone else from sending transactions if they somehow get access to your private key — it’s not a block, just a confirmation guard. Rabby Wallet
Privacy & Non-Custodial Design
Rabby doesn’t collect or store personal data. All sensitive information (like private keys or seed phrase) stays on your device. Rabby Wallet
Because of this, your privacy is stronger — no central server holds your wallet data. Rabby Wallet
Open-Source & Audited
The wallet is open-source, so anyone can inspect its code, which helps transparency and trust. Rabby Wallet
Rabby also undergoes regular security audits by third-party firms to identify vulnerabilities. Rabby Wallet
Hardware Wallet Integration
Rabby supports hardware wallets like Ledger and Trezor. This means you can keep your private keys offline (on hardware) while using Rabby’s UI to interact with dApps. Rabby Teachable+1
This is especially valuable for users holding significant assets who want the security of cold storage plus the flexibility of a Web3 wallet. Rabby
Multi-Chain Asset Management
You can manage tokens across multiple EVM chains (Ethereum, Polygon, Arbitrum, Optimism, BSC, etc.) from a single interface. Rabby Teachable
Rabby provides a unified dashboard showing your token balances, DeFi positions, and potentially NFT holdings. rabbywallet.m-pages.com+1
Phishing / Scam Detection
Rabby flags suspicious or phishing transactions. It helps users by warning when a transaction seems risky. Rabby FAQ+1
It also marks “scam transactions” in the history to alert users. Rabby Wallet
No Data Collection
According to Rabby’s own privacy guide, they do not store your private key or seed phrase on their servers. Rabby Wallet
All transaction simulations, previews, and risk analyses happen locally on your device, ensuring maximum privacy. Rabby Wallet
How Rabby Wallet Works: A User’s Flow
To understand the practical user experience, here is how a typical user might interact with Rabby Wallet:
Install & Setup
The user installs Rabby as a browser extension (available on Chrome Web Store). Chrome Web Store
On first launch, the user can create a new seed phrase (wallet) or import an existing wallet (e.g., from MetaMask). Reddit+1
It’s strongly recommended to securely back up the seed phrase (offline) — because as a self-custodial wallet, losing this means losing access to funds.
Connecting to dApps / Using DeFi
When the user visits a dApp, Rabby auto-detects the network required (e.g., Polygon, Arbitrum) and switches accordingly. Rabby
When the user initiates a transaction, Rabby simulates the transaction to show the expected outcome (how balances change, gas costs, whether any tokens are approved, etc.). Rabby FAQ
If the transaction involves a contract or address with risk, Rabby warns the user via its risk scanner. secure-rabby-en-faq.teachable.com+1
Managing Token Approvals
The user may approve tokens for use by smart contracts. Rabby warns about “risky approvals” and unlimited allowances. secure-rabby-en-faq.teachable.com+1
Periodically, the user can go to the batch-revoke tool to revoke token permissions that are no longer needed. Rabby Wallet
Gas / Transaction Fees
Rabby reportedly allows users to “top-up” gas in some way (using stablecoins or other options) so they don’t get stuck for lack of native gas. Metana
This is especially helpful on side chains or when users don’t want to keep a large amount of the chain’s native token for gas.
Hardware Wallet Use
For more security, the user can connect Rabby to their hardware wallet (Ledger / Trezor). Rabby FAQ
Signing transactions still happens via Rabby’s UI, but the private key never leaves the hardware device.
Portfolio Overview
Within Rabby, users can see their balances across chains: token holdings, DeFi positions, and possibly NFTs. rabbywallet.m-pages.com
Integration with DeBank (its parent analytics platform) allows detailed portfolio insights. Rabby Tokens

Limited to EVM: Rabby only supports EVM-compatible chains; it does not support non-EVM chains like Solana or Bitcoin natively. Rabby FAQ
Reported Incidents:
User Interface / UX Critiques:
According to some Reddit users, the UI can be inconsistent (especially between extension and webview), and some screens may feel clunky or unclear. Reddit
The mobile app (in past user feedback) was less mature; in one case, the mobile version could not sign transactions independently, relying on another wallet. Reddit
Trust Issues:
There’s a significant number of negative reviews on Trustpilot. Users complain about abrupt removal of features (e.g., removing support for certain chains) and poor support. Trustpilot
According to reviews, Rabby once “stopped supporting PulseChain” without a clear explanation, which frustrated many users. Trustpilot
User Feedback & Reputation
User sentiment about Rabby Wallet is mixed, with many praising its security features and usability, but also some strong criticisms — especially around safety and trust.
Positive Feedback
On Reddit, several users say:
“Rabby is a total gamechanger. The security when signing transactions … is ten times that of MetaMask.” Reddit
Others highlight its anti-phishing and scam-warning features:
“The anti phishing and anti scam measures … makes me not want to try any other wallet.” Reddit
Many appreciate the integration with DeBank, giving them a unified, data-rich view of their DeFi positions. Reddit
Concerns / Criticisms
The Trustpilot rating is very low (1.1 / 5), with criticisms about support, abrupt changes (“wallet will stop support … your balance will show zero”), and perceived poor handling of user concerns. Trustpilot
As mentioned, there were fake versions of Rabby on iOS, leading to reports of users losing funds. Reddit+1
Some users allege that parts of the code are not truly open source, or that there might be hidden risks. Reddit
There are also reports of past security incidents. For example:
“I have recently added three different wallets … And all of them were hacked … downloaded client from official site.” Reddit
A more technical / UX criticism: certain parts of the interface (like send screens) were inconsistent, and some buttons are disabled without clear explanation. Reddit
Comparison with Other Wallets
To understand Rabby better, it helps to compare it with other popular wallets:
MetaMask
Manual network switching vs Rabby’s automatic switching. Rabby’s automation is a strong UX win. rabbywallet.m-pages.com
MetaMask lacks built-in transaction simulation; Rabby’s simulation offers a major safety advantage.
MetaMask is more established, but Rabby is more DeFi-optimized.
Hardware wallets (Ledger, Trezor)
Rabby supports hardware wallets, so it doesn’t compete directly — rather, it complements. You can use Rabby’s UI + a hardware wallet’s security.
Some users prefer to just use hardware wallet interfaces; but Rabby offers a richer UI for interacting with dApps.
Other multi-chain wallets
There are other wallets supporting EVM chains, but Rabby stands out for its user safety tools (simulation, risk alerts) and DeFi focus.
Best Practices & Tips for Using Rabby Safely
If you're planning to use Rabby Wallet (or already using it), here are some good practices to reduce risk and get the most out of it:
Always Download from Official Source
Use the official website (e.g., rabby.io) or verified sources. This helps avoid malware or fake versions.
According to Rabby’s own security guidance, always verify you're using the correct link. Rabby Wallet+1
Secure Your Seed Phrase
Write down the seed phrase on a physical paper and store it securely (safe, vault, etc.).
Do not store it in a cloud folder or screenshot it.
Use Hardware Wallet for Big Funds
If you’re storing a large amount, connect Rabby to a Ledger or Trezor for added security.
This ensures that transaction signing happens in a secure environment.
Carefully Review Transaction Simulation
Before signing anything, go through the transaction preview in Rabby.
Check the balance change, gas costs, and which tokens are being used.
Use Whitelist Feature
Add frequently used and trusted addresses to Rabby’s whitelist.
This gives an additional confirmation layer when sending funds to non-whitelisted addresses.
Revoke Approvals Regularly
Use Rabby’s batch-revoke tool to manage which smart contracts have access to your tokens.
This reduces the “attack surface” in case some contract becomes malicious or compromised.
Be Aware of Phishing / Scams
Rabby warns of potential risks, but don’t rely solely on it.
Confirm URLs, don’t click suspicious links, and beware of unsolicited messages asking for your seed phrase or private keys. Rabby itself never asks for your seed phrase. Rabby Wallet
Use official communication channels for support, not random DMs.
Stay Updated
Keep Rabby’s extension updated — newer versions often bring security patches.
Follow Rabby’s official blog / GitHub for updates, audits, or warnings.

The Future of Rabby Wallet
Given its strong feature set and the backing of DeBank, Rabby is well-positioned for continued growth. Here are some possible future trajectories and opportunities — as well as risks — to watch out for:
Mobile Wallet Maturity
If Rabby builds a strong, secure mobile app (with proper verification), it could significantly widen its user base.
Addressing the issue of fake mobile apps is critical; stronger identity verification or official app-store partnerships could help.
Expansion to More Chains
While Rabby currently supports many EVM-compatible chains, expanding support (or deepening integrations) could make it more attractive.
Users may want to see non-EVM support in the future — though that’s a big technical challenge.
Deeper DeFi Integrations
Rabby could partner with more DeFi platforms to offer in-wallet farming, staking, or governance features.
In-wallet swap / aggregator features could become more powerful.
Improved Security Tools
More advanced risk-detection capabilities (e.g., analyzing transaction history, behavioral heuristics) could make Rabby even safer.
On-chain analytics: Rabby might integrate more tightly with DeBank’s analytics to give richer portfolio risk insights.
Community Growth & Governance
Open-source contributions: As more developers audit or contribute to Rabby’s codebase, trust could grow.
Potential for community governance: If Rabby introduces a token / governance model, users could have a say in its direction.
Regulatory Challenges
As regulators increasingly look at the crypto infrastructure, self-custody wallets may face scrutiny, particularly if they offer certain financial services.
Rabby will need strong compliance practices (without compromising decentralization) to navigate legal challenges.
Conclusion
Rabby Wallet is one of the more advanced Web3 wallets targeting DeFi users who care about security, transparency, and cross-chain convenience. Its combination of transaction simulation, risk alerts, auto network switching, and batch revoke makes it a powerful tool for anyone interacting seriously with dApps.
Its self-custodial nature means that you are fully in charge of your assets — which is both a strength and a responsibility. For users who are careful, use hardware wallets, and critically review their transactions, Rabby can be an excellent choice. On the flip side, reports of phishing clones, user-reported hacks, and mixed trust reviews mean one must stay vigilant.
If you’re someone who does a lot of DeFi, trades across multiple EVM chains, or just wants a safer Web3 wallet experience, Rabby is definitely worth considering. But like all crypto tools, it’s only as safe as its user.
