Your private keys never leave this application. It generates a 12-word recovery phrase locally. No registration or personal data submission is required.

Pin the icon next to your address bar. Access your portfolio, sign dApp approvals, and check gas prices without opening a new tab.

Mango Wallet for Chrome, Firefox, Brave, and Kiwi Browsers

Install this extension directly from the official store of your chosen navigator; verification of the developer's name ensures you avoid fraudulent copies.

Transaction fees are calculated in real-time. The tool fetches current network conditions before you sign, allowing you to choose between speed and economy for every transfer. It displays the cost in your local currency.

Your private keys never leave the local device storage. All encryption and signing operations happen within the extension's isolated environment, not on a remote server.

Configure custom RPC endpoints for full network control. This lets you interact with alternative providers or specific testnets, bypassing default infrastructure during congestion.

Pin the most-used dApps for single-click access. The interface supports drag-and-drop organization of bookmarks to DeFi platforms and NFT marketplaces, streamlining your routine interactions.

Review the granular permission settings. You can adjust token visibility, connection timeouts for visited sites, and automatic lock periods, tailoring the security profile to your activity level.

Installing and Setting Up Mango Wallet in Your Browser

Navigate directly to the extension store of your chosen application–Chromium-based, Mozilla's platform, or others supporting unpacked extensions. Locate the utility by its exact name and initiate the addition process; confirmation is typically a single click. The icon will appear beside your address bar once the operation finishes.

Initial configuration demands attention. Click the new toolbar symbol to activate the setup interface. You must generate a new seed phrase or import an existing one–this step is non-negotiable for security. Record the 12-word mnemonic on physical media, never digitally. Finalize by establishing a strong password specific to this extension.

Adjust preferences. Access settings via the extension's menu. Enable transaction previews and auto-lock after 5 minutes. For Kiwi or Brave, check “Allow in incognito” if needed. Add frequently used token addresses to your asset list to track balances without manual searches. The tool is now operational.

Managing and Swapping Cryptocurrencies Directly from the Extension

Connect your existing self-custody portfolios directly within the add-on's interface; Ledger and Trezor hardware devices are supported for immediate balance checks without moving assets.

View aggregated holdings across multiple networks in a single dashboard. Real-time price feeds from over ten decentralized and centralized sources ensure your portfolio's total value is accurate, updating every thirty seconds.

Execute token exchanges across fifteen different blockchains. The built-in aggregator scans dozens of decentralized exchanges to present the optimal rate, including potential gas fees, before you confirm. Slippage tolerance is adjustable from 0.1% to 5%.

Set automated limit orders for Ethereum and Polygon assets. Define your target buy or sell price, and the order executes trustlessly when market conditions are met, even while the application is inactive.

Review a complete, on-chain audit trail for every transaction. Each action generates a permanent record with timestamp, network status, contract address, and gas expenditure, exportable for tax reporting.

Enable transaction simulation for previews. This feature estimates final token amounts, including all fees, and warns of high-risk interactions before signing, preventing costly errors.

Connecting Mango Wallet to Decentralized Applications (dApps)

Click the extension icon in your toolbar to open the interface before visiting a dApp's website. This action pre-loads the client, ensuring it's ready to detect connection requests immediately. Most applications on networks like Ethereum, Polygon, or Solana will automatically present a pop-up modal listing detected providers; select the one matching your extension's name. If no prompt appears, locate a “Connect Wallet” button on the dApp's page, typically in the top-right corner.

Authorization requires explicit approval for each site. Review the permission details in the connection request window carefully:

The specific network or chain ID the application is requesting. The public address(es) it will be able to view. Whether it's asking for permission to send transaction requests on your behalf.

Never approve requests asking for your private keys or secret recovery phrase.

For transaction signing, a separate pop-up will appear for every operation. Scrutinize the data: token amount, recipient address, gas fees, and the smart contract function being called. Incorrect contract interactions are irreversible. Adjust gas limits for complex swaps or NFT minting to prevent failed transactions, which still incur costs. Keep the extension updated to maintain compatibility with the latest EIP-712 standards for structured data signing.

Disconnect from dApps via the extension's own “Connected Sites” management panel, not just the dApp's interface. This revokes permissions fully. Clear pending transactions from the same panel if the network is congested. Use separate browser profiles for different accounts to avoid linking your activities across protocols. Regularly audit connected app permissions and revoke any unused.

FAQ: Does this wallet work on all Chromium browsers like Brave and Kiwi?

Yes, the Mango wallet extension is designed to be compatible with any browser that supports the Chrome Web Store extensions. This includes Chrome, Brave, Kiwi, and other Chromium-based browsers. For Firefox, you can install it directly from the Mozilla Add-ons website. The core functionality is consistent across all these platforms.

I use multiple browsers. Do I need to set up my wallet separately in each one?

You will need to install the extension in each browser. Your wallet data, like seed phrases and private keys, is stored locally within that specific browser's installation. It does not sync automatically between different browsers or devices. So, if you install it on Chrome and Firefox on the same computer, you'll have to set up or import your wallet separately in each. This is a security feature that keeps your keys under your control.

How does Mango wallet handle my secret recovery phrase?

The Mango wallet operates as a non-custodial wallet. This means you alone control your secret recovery phrase. The phrase is generated and stored locally on your device when you create a wallet. The extension itself never transmits, stores, or has access to this phrase. It is your responsibility to write it down and keep it safe offline. If you lose access to the browser or your computer, this phrase is the only way to restore your wallet and funds.

Can I switch networks, like from Ethereum to Polygon, with this wallet?

Yes. The Mango wallet supports multiple blockchain networks. You can typically switch between networks like Ethereum, Polygon, Binance Smart Chain, and others directly within the extension's interface. Look for a network selection menu, often near the top of the wallet's pop-up window. You may need to manually add the network details for some less common chains, but guides for this are usually provided in the wallet's support documentation.
