Why choose the MetaMask app?

1) Security-first by design

The MetaMask app generates and stores your keys locally on your device. Your Secret Recovery Phrase (SRP) is the master key to your wallet—MetaMask never sees it and cannot recover it for you. With biometrics support on mobile, password protection, and optional connections to hardware wallets, you get robust layers of security from the start.

2) Control, privacy, and portability

With the MetaMask app, you are in control: move assets between accounts, connect to dApps selectively, and choose which network to use. Your data stays private unless you choose to share it with a site. Need to switch devices? Import your wallet using your Secret Recovery Phrase to regain access instantly.

3) Seamless dApp access across Web3

Discover DeFi, gaming, NFTs, DAOs, and more. On mobile, use the built-in browser to explore decentralized applications directly. On desktop, the extension connects securely to compatible websites with a single click, giving you frictionless access to Web3 experiences.

4) Built-in tools that elevate your flow

• ★ Buy crypto in-app via integrated providers (availability varies by region)
• ★ Swap tokens with optimized routes sourced from multiple liquidity sources
• ★ NFTs displayed in a clean gallery view (where supported)
• ★ Portfolio view for a clear snapshot of tokens across accounts and networks

How the MetaMask app works

Getting started is quick. After installing the MetaMask app on mobile or the browser extension on desktop, you can create a new wallet or import an existing one. From there, fund your address, connect to dApps, and start exploring. Here’s the flow in simple steps:

1. Install the MetaMask app for iOS/Android or the extension for Chrome, Firefox, Brave, or Edge.
2. Create or import your wallet. Back up your Secret Recovery Phrase offline—never share it.
3. Secure with a strong password and enable device biometrics (mobile) if available.
4. Fund your wallet by receiving tokens or buying crypto in-app via providers.
5. Connect to dApps and confirm transactions directly in the MetaMask app.
6. Manage tokens and NFTs, track activity, and adjust network and gas settings.

Supported networks and tokens

The MetaMask app supports Ethereum and many EVM-compatible networks. You can add networks manually or through trusted prompts from verified dApps. The app supports ERC-20 tokens and popular NFT standards (such as ERC-721/1155), with visibility depending on network support and your chosen settings.

Gas, fees, and transparency

Transactions on-chain require network gas fees paid to validators or miners. The MetaMask app lets you customize gas where applicable—choose faster confirmations or lower fees depending on network conditions. Built-in swaps include a transparent service fee that’s shown before you confirm, so you always understand your costs.
