Rabby Wallet Setup Connecting to Dapps and Managing Recovery Phrases

Begin by acquiring the browser extension from the official Chrome Web Store or Firefox Add-ons portal. The setup process requires you to establish a fresh vault or integrate an existing one using a 12 to 24-word secret phrase. This phrase is the absolute key to your assets; its security is non-negotiable. Store it physically, offline, and never share it digitally.


Once operational, this tool automatically detects the correct network for each decentralized application you visit, eliminating manual chain switching errors. It supports over 140 networks, including Ethereum, Arbitrum, and Polygon, by default. You can authorize interactions with smart contracts after the interface presents a clear, simulated transaction outcome, highlighting potential balance changes before you confirm.


Should you need to migrate your access credentials to a new device, the process relies solely on your original secret phrase. Input those words in the exact order during the "Import" flow within the new extension. There are no account passwords stored on servers; sovereignty over your funds is entirely dependent on your custody of that phrase. Regularly verify you are using the authentic extension to avoid phishing copies.

Downloading and Setting Up the Rabby Browser Extension

Acquire the software exclusively from the official Chrome Web Store or Firefox Add-ons portal. Third-party sites pose significant security risks.


Click the "Add to Browser" button on the store page. Confirm the installation when your browser prompts you. The extension icon will appear in your toolbar upon completion.


Select "Create a New Vault" for a fresh setup. You will define a strong password; this encrypts local data but does not function as a seed phrase. Store this password securely.


Next, you must record your secret recovery phrase. The tool will generate 12 unique words. Write these on paper and keep them offline. Digital screenshots or text files are unacceptable.


Verify your phrase by selecting the words in the correct sequence when prompted. This step finalizes vault creation.


You can now import existing accounts using their private keys or seed phrases. Navigate to the account management section and choose the appropriate import method.


For daily access, use your defined password. The secret phrase is only required for restoring your entire vault on a new device or browser.

Creating a New Wallet or Importing an Existing Account

Select "Create a new vault" for a fresh setup. This generates a unique 12-word secret recovery phrase offline. Write these words in exact order on paper; digital storage creates risk. Confirm the phrase by selecting each word sequentially. A strong password encrypts the local vault data.


Use "Import an existing vault" to restore access. Enter your 12 or 24-word mnemonic phrase precisely. Single typos cause failure. For individual private keys, choose "Import a private key". Paste the 64-character hexadecimal string directly; avoid manual entry.


After import, immediately verify asset visibility across supported networks. Check transaction history for completeness. For new vaults, deposit a small amount first, conduct a test transaction, then move larger balances.

Connecting Rabby to a Decentralized Application

Navigate to the dApp's website and locate its "Connect OneKey Wallet to a dApp" or "Sign In" button, typically found in a page header.


Select the browser extension option from the modal window that appears; avoid mobile wallet QR codes.


Your installed browser extension will trigger a pop-up interface. Choose the specific account you intend to link from the displayed list.


Review the permission request detailing the network access the application seeks. Confirm the action only if these parameters match your expectations for the interaction.


Successful linkage is often signaled by the dApp's interface updating to show your truncated public address. The extension icon may also change state.


For subsequent visits, the application might automatically recognize your prior authorization. Manual reconnection from the site's interface is occasionally required.


To sever a link, access the extension's main menu, find the "Connected Sites" section, and revoke access for any application you no longer use.

Managing Network Approvals and Transaction Security

Audit every network addition request; reject unrecognized RPC endpoints immediately. This prevents traffic redirection to malicious servers.


Maintain a strict whitelist for automatic network switches. Disable this feature for experimental or lesser-known decentralized applications to retain full manual control over your active chain.

Scrutinize the simulation panel for every transaction. Look for unexpected token approvals, transfer directions, or new contract interactions not part of your intended action.


Set a global spending cap for each token approval instead of granting unlimited permissions. Regularly review and revoke old allowances using your interface's approval management tool to minimize exposure from dormant sessions.


Verify the full contract address and its verification status on a block explorer before confirming high-value transactions. Do not rely solely on dapp interface labels.

Recovering Your Account Using a Secret Recovery Phrase

Access the "Import" or "Add Account" function within your software's interface. Select the option to restore using a seed phrase.


Enter your 12 or 24-word mnemonic phrase with absolute precision:


Type each word in the exact sequence, from first to last.
Verify spelling; a single mistake will block access.
Use a single space between words, no commas or extra lines.


During this process, you will establish a new confidential code. This code is distinct from your recovery phrase and secures routine entry to the interface.


Create a robust code exceeding 10 characters.
Incorporate uppercase letters, numbers, and symbols.
Confirm the code by entering it a second time.


Finalize the procedure. Your portfolio, including all tokens and transaction records, will repopulate. The restoration is complete once your asset balances appear.


Post-restoration actions:


Immediately validate all authorized application connections under the settings menu. Revoke any unfamiliar permissions.
Conduct a small test transaction to confirm full functionality.
Store your recovery phrase offline. Never save it in cloud storage, email, or screenshots.

Q&A:
I downloaded Rabby from rabby.io, but my antivirus flagged the installer. Is this safe?

This is a common concern. The Rabby wallet is an open-source product developed by the reputable DeBank team. Antivirus software often flags cryptocurrency wallets because they interact with smart contracts and can sign transactions, which is a pattern similar to some malware. It's a precaution, not a definite sign of malicious software. To be safe, always ensure you download Rabby only from the official website, rabby.io, or the official browser extension stores like Chrome Web Store. Do not download installers from third-party links or forums. The warning is typically a false positive, but verifying the download source is the most critical security step.

Why does Rabby show a "Pre-transaction Simulation" and what do the red warnings mean?

Rabby's Pre-transaction Simulation is its core security feature. Before you sign any transaction, it simulates the outcome directly in the extension window. It shows you exactly which assets will move, the estimated balance changes, and any potential risks. Red warnings are critical alerts. They can mean several things: the transaction you're about to sign could give a dapp unlimited access to a specific token (infinite approval), the dapp contract has known security issues, or the transaction involves interacting with a brand new or suspicious token. You should always stop and carefully read any red warning. It's designed to prevent common exploits that other wallets might not highlight as clearly.

Can I use my existing MetaMask seed phrase to set up Rabby?

Yes, you can. During the initial setup, Rabby will give you options like "Create a New Wallet" or "Import an Existing Wallet." Choose import. You can then enter your 12 or 24-word secret recovery phrase from MetaMask (or any other compatible wallet). Rabby will restore your addresses and their associated assets. This process does not affect your MetaMask installation; both extensions can run simultaneously using the same accounts. However, be extremely cautious: only enter your seed phrase into the Rabby extension after you have verified its authenticity. Never type it into a website pop-up or any other software.

I connected to a dapp but now want to revoke its permissions. How do I do that in Rabby?

Rabby has a built-in tool for managing dapp permissions. Click the Rabby extension icon and go to the "Connected Sites" section. Here you'll see a list of all websites your wallet has interacted with. You can disconnect from any of them with one click. For more serious control over token allowances, use the "Approval" feature in Rabby's main interface. It scans your addresses and lists all the tokens where you've granted spending permissions to dapp contracts. For each entry, it shows the dapp name and the approved amount. You can then revoke the approval or adjust it to a lower, safer limit directly through this interface, often for a small network fee.
