About Rabby Crypto Wallet
Rabby is a non-custodial wallet extension made by DeBank, and its main goal is to let you jump between blockchains without hassle.
It works on over 100 EVM chains, swaps networks automatically, lets you run a test transaction first, checks pre-signed messages for danger, and even pairs with Ledger or Trezor hardware keys .
People like the tidy layout and extra phishing guards, often saying it feels tougher than MetaMask . The catch is that not every line of code is public-some key modules cant be built from GitHub alone
The mobile app is still getting polish, and scammers have stuffed the iOS store with fake copies, leaving funds in play .
Users also grumble because support for PulseChain vanished overnight, and no solid reason was given. All in all, Rabby packs power and safety, yet you should vet every promise yourself.

What Blockchains Does Rabby Support?
Ethereum
Rabby Wallet fully supports Ethereums main network, the leading and most trusted chain for smart contracts and dApps. From your browser, you can dive into DeFi apps, trade NFTs, vote in DAOs, and use any service built on Ethereum.
Before signing a transaction, Rabby shows a clear gas estimate, simulates the outcome, and flags possible risks, so you know exactly what will happen. The wallet also swaps chains automatically, so you never have to hunt for the right network.
With fast token management and one-click dApp access, Rabby makes Ethereum trading safe, simple, and stress-free for everyday users.
Arbitrum
Rabby now works with Arbitrum, an Ethereum Layer 2 that speeds up transactions and cuts costs. Because of Rabbys auto-detection, you reach Arbitrum dApps the moment you log in-no network switch needed.
The wallet even previews each Arbitrum deal, warning you about hidden risks before the final click. Whether you farm, swap, or bridge tokens on Arbitrum, Rabby makes every step smoother and safer.
Its built-in DeFi tools, paired with Arbitrums tiny fees, suit traders who want quick, low-cost Layer 2 action. With Rabby, your Layer 2 adventures stay fast, secure, and wallet-friendly.
Optimism
Rabby Wallet also supports Optimism, another Layer 2 helper for Ethereum. Optimism cuts transaction times and fees while staying anchored to Ethereums core security. Thanks to Rabby, you enter Optimism dApps straight away, with no fiddling for RPC settings.
The wallet previews every deal and scans for red flags before you hit sign. In the busy world of DeFi, that extra glance can save money and stress. Whether you trade, lend, or bridge assets on Optimism, Rabby mixes ease of use with solid safety tools.
Polygon
Rabby now works on Polygon, the busy Layer-2 network that eases pressure on Ethereum and charges almost nothing to send tokens.
With Rabby, you can hop straight into Polygon dapps like swap shops, NFT markets, or play-to-earn games without extra setups. Its auto-chain switch and transaction preview catch silly mistakes before they cost you.
Fast, cheap blocks keep everyday users and builders glued to Polygon; Rabby pads that speed with a tidy, security-first wallet. Whether youre staking, swapping, or just moving assets around, Rabby keeps your Polygon tasks safe and easy.
Security: How Safe is Rabby Wallet?
Rabby works with a security-first mindset, and you can see it in every feature. Its Transaction Simulation tool lets you test swaps before actually sending them, so you steer clear of shady contracts.
Approval Warnings pop up when you try to give a token new access, telling you if the receiving address is unknown.
Rabbys code is partly open-source. Most front-end files and key modules are public, but the full code is not yet buildable, leaving some privacy-minded folks uneasy.
Hardware Wallet Support locks your keys offline, which slashes the odds that hackers will grab them.
Still, watch out for phony mobile apps. Rabby does not yet offer an official iOS version, and clones posing as it have snatched seed phrases and stolen funds.
Key Features of Rabby Wallet
Automatic Network Switching
One feature that really makes Rabby shine is automatic network switching. If you visit a dApp on Arbitrum while your wallet is still on Ethereum, Rabby either prompts you or swaps chains behind the scenes. That tiny magic trick keeps you from the usual network mismatch errors and makes moving money around DeFi much smoother.
Transaction Simulation
Before any swap or approve goes on-chain, Rabby runs a quick simulation. You get a snapshot showing what tokens leave, what arrives, and whether the contract looks sketchy. With this peek ahead, users dodge unintended losses and shady contracts.
Pre-Sign Risk Alerts
Whenever you click Sign, Rabby does a rapid scan for hidden danger signs, like oversized approvals or surprise balance drains. If anything seems off, you see a bright warning. That extra set of eyes helps users feel safe and cuts down phishing success.
Multi-Chain Support
Rabby works with over 100 EVM chains, from Ethereum mainnet to tiny Layer 2 playgrounds. Because the RPCs and chain IDs load automatically, you never have to copy-paste settings or hunt for obscure endpoints. No matter where the dApp lives, Rabby clears the path so you can dive straight in.
Hardware-Wallet Connection
Rabby now links with Ledger and Trezor, so you can plug in your hardware wallet whenever you want that extra safety. Signing any big trade or long-term move with your device makes it much harder for hackers to steal funds.
DeFi-Friendly Dashboard
The interface was built for DeFi users, showing token balances, approvals, and simulated outputs front and center. It feels like a dashboard, not just a plain list, so you see what matters at a glance.
Is Rabby Wallet safe to use?
Rabby Wallet earns a solid safety rating for most desktop users. It shows every pending move with clear previews, warns you before signing anything risky, and lets collectors connect Ledger or Trezor for an extra security layer.
Made by DeBank, the wallet puts transparency first for everyone exploring DeFi. Right now, though, an official Rabby app for phones does not exist. That absence leaves room for clone apps on iOS and Android, and several fake copies have shown up already.
The knock-off software can grab seed phrases and put your funds at serious risk. To stay safe, always pull Rabby from its main site or from well-reviewed browser extension stores.
