Rabby Wallet review for 2026 — security model, audits, fees, chain support, and an honest comparison with MetaMask for EVM and DeFi users.
If you are a frequent signer of contracts, then Rabby is a better choice, as it slows you down before a bad transaction goes through. Even in terms of raw chain coverage and ecosystem size, MetaMask remains the clear winner. Here’s a breakdown of where each one is falling short.
What is Rabby Wallet is all about.
The creators of DeFi portfolio tracker DeBank have developed Rabby in 2021 and published it under OPCODE LABS PTE. Singapore-based LTD. It is not custodial, meaning that it does not store your keys, and Rabby never comes into contact with them. No sign-up, no KYC, install and go. It is available as a browser extension (Chrome, Brave, Edge), a desktop application for macOS and Windows, and mobile applications for iOS and Android.
The layout should be familiar to you if you’ve used MetaMask. The difference lies in what you do in the blink of an eye before you click “Sign.
What is special about the Security Model?
Two features in the list are much more important here.
It is 100% open source. The codebase is available on public GitHub repos under the MIT license on the extension, mobile and desktop platforms. The code that creates keys and signs transactions is open source. For comparison, MetaMask has been source-available on a proprietary license since 2020, though you can view the code, it’s not in the true spirit of open source.
It has undergone repeated third party audits and Rabby is not afraid to reveal the results instead of hiding them. Least Authority reviewed the mobile app in October 2024 and the extension in December 2024, and re-reviewed the extension in September 2025.
In August 2025, SlowMist performed its audit and reported 3 issues, which were all at the “Suggestion” level. Least Authority had one finding rated as medium severity that remains open with auditors rating the potential impact in the real world as low. A wallet that doesn’t hide the finding instead publishes an unresolved finding is doing something that most competitors aren’t doing.
The track record: there is one incident of note when it comes to 2022, there’s a Rabby Wallet Swap contract exploit. It didn’t expose user keys/wallets, just the swap function and it was patched by the team. So if you’re going to publish, do a check, as per source above, which is third-party coverage and not Rabby’s own incident disclosure.
The functionality which really makes a difference in your daily life: pre-sign transaction simulation. Rabby walks you through the transaction before it is approved, letting you know what the balance changes will be, what tokens you will be approving, and what permissions to the contract you will be giving in plain English, not raw hex. It also warns you about contracts that are risky, addresses you’ve already encountered in phishing attacks, and if the tokens are being approved with a wide wallet, before you click Sign.
The first is Chain Support and the second is the One Real Limitation.
Rabby supports over 100 EVM compatible chains and testnets, including: Ethereum, BNB Chain, Arbitrum, Base, Optimism, Polygon, Avalanche, zkSync, Linea etc. The number of chains continues to change as new chains are added, so any number that you read (92, 100 plus, 140 plus, etc.) is a snapshot of the chain at a particular time – not a spec.
The silent hero is the automatic network switching: connect to a dApp and Rabby Wallet will detect the appropriate network and switch for you. Despite everything, you still have to add and switch networks by hand in MetaMask, and unfortunately, that’s the type of friction that can cause you to approve a transaction on the wrong chain.
The restriction is similarly stringent: Rabby is EVM-only. No Bitcoin, no Solana, no XRP, no Tron. If you have a portfolio that is 100% on EVM chains, it doesn’t cost you anything. If you already have a wallet for BTC and SOL, then you will also be using a second wallet, no matter what else Rabby does, well done.
A booklet that explains the real cost of your car.
Rabby Wallet is free to use for standard transactions, standard transfers, connection to dApps, and holding assets — no wallet-level fees on any of these. The only built-in cost is the swap amount, which Rabby Swap will charge you (0.25% of the swap amount, plus network gas fees, which you will see in the quote before confirming a swap). You can direct swap instead of swap in wallet and you will avoid that fee.
The Mobile App, namely.
The vast majority of Rabby coverage online is focused on the browser extension, and only superficially mentions the mobile app, which isn’t the same. Rabby Wallet has an average rating of 4.7 stars on Google Play based on nearly 7,100 reviews and 500K+ installs. Fans who have been using it for a while say it’s their everyday wallet and they believe it’s quicker to load than when they first installed it, and the features are released more regularly.
It’s not spotless. The fingerprint unlock flow has been a recurring feature in the few recent reviews that have been written, with one Pixel 10 user stating that the fingerprint screen keeps freezing after the update, but that the desktop and tablet versions don’t experience the issue. It’s a true, live friction point, and one that will have to be confirmed on a device-specific test before putting complete trust in the mobile app for anything other than checking your balance on the go.
Rabby Wallet vs. MetaMask: The Actual Breakdown
| Rabby | MetaMask | |
|---|---|---|
| Code | Fully open source (MIT) | Source-available, proprietary license |
| Network switching | Automatic, per dApp | Manual |
| Chain coverage | 100+ EVM chains only | EVM plus non-EVM chains via Snaps (Bitcoin, Solana) |
| Pre-sign simulation | Built into every transaction by default | Available, generally described as less detailed in side-by-side tests |
| Ecosystem size | Smaller, growing fast among active DeFi users | Largest install base, most dApp integrations by default |
| Built-in swap fee | 0.25% | Comparable built-in fee — check current MetaMask terms before assuming a number |
Both wallets are safe in use. It’s not the software that’s the danger when using either of them, it’s the user rushing through an approval. The only thing that Rabby Wallet changes is how hard getting rushed is.
But MetaMask isn’t resting on its laurels either Agent Wallet, the self-custodial wallet for AI agents, with batch swaps and gas abstraction, was a recent addition for AI agents (as of August 2026). Rabby is not an EVM, and it lacks an agent tooling, so if those are concerns for you, then it is fine to keep Rabby Wallet installed on the same system as MetaMask, instead of replacing it. There are many active DeFi users who use both, MetaMask for breadth and Rabby Wallet for anything that could actually cause a loss if a bad signature is used.
Who Rabby Wallet Is For
You deal with contracts every day like swaps, bridges, new protocols, and you want a layer of simulation between you and a bad signature.
You’ve grown weary of manually switching networks to connect to each chain.
You would like to read the code your wallet is using, rather than take the word of a vendor.
Who Should Look Elsewhere
You have assets off blockchain other than EVM, like Bitcoin, Solana, and require a single wallet.
The primary goal is to be as compatible with dApp as possible now, rather than the wallet with the most secure wallet model.
You’re handling significant money on a phone and do not want to deal with a bug that only issues on Android.
Final Answer
Rabby’s recommendation for EVM chains is for those who are actively working with DeFi, and for the code being open-source, the audits that have been publicized, and the pre-sign simulation, it really is a higher level of security than MetaMask’s default. It’s not a replacement for a hardware wallet if you are holding significant amounts of money; it’s not suitable if your portfolio consists of anything other than EVM tokens.
If you aren’t either of those aforementioned groups, it is free to import your existing seed phrase into Rabby along with MetaMask, and provides a real level of protection at the point where it truly matters: the signature.
