How to use MetaMask on your mobile device?

Setting Up MetaMask on Mobile

1. Download the MetaMask app from the Apple App Store or Google Play Store. Ensure you are installing the official application developed by ConsenSys to avoid counterfeit versions. Once installed, open the app to begin the setup process.

2. Choose the option to create a new wallet. You will be prompted to set a strong password that will be required each time you access the app. This password does not recover your account but adds a layer of local security.

3. Carefully back up your secret recovery phrase. The app will display a 12-word phrase that must be written down in the correct order. This phrase is the only way to restore your wallet if you lose access to your device. Never share it, take screenshots, or store it digitally.

4. Confirm your recovery phrase within the app by selecting the words in the correct sequence. This step ensures you have securely recorded the phrase.

5. After confirmation, your wallet is ready. You can now view your public Ethereum address, which you can use to receive tokens from others.

Managing Assets and Transactions

1. Tap on the “Assets” tab to view all your supported tokens. By default, ETH and a few major tokens like DAI or USDC may appear if they are present in your wallet.

2. To add a custom token, go to the settings menu and select “Add Token.” Choose the “Custom Token” option and enter the contract address, token symbol, and decimals. Ensure the contract address is verified from a trusted source like Etherscan to prevent scams.

3. To send cryptocurrency, tap the “Send” button, enter the recipient’s wallet address, and specify the amount. Always double-check the address, as transactions on the blockchain are irreversible.

4. Before confirming, review the network fee (gas fee) displayed. You can adjust the speed of the transaction—faster confirmations require higher fees. Choose based on network congestion.

5. After submitting, you can track the transaction status in the “Activity” tab. A green checkmark indicates successful completion on the blockchain.

Connecting to Decentralized Applications (dApps)

1. Open the “Browser” tab within the MetaMask mobile app. This built-in browser allows secure connections to Web3 sites without exposing your seed phrase.

2. Navigate to a decentralized finance (DeFi) platform such as Uniswap, Aave, or PancakeSwap. When you interact with features like swapping or staking, a connection prompt will appear.

3. Approve the connection request from MetaMask. This grants the dApp read access to your wallet address and the ability to request transaction signatures. Never connect to suspicious or unverified websites.

4. When executing actions like providing liquidity or claiming rewards, the dApp will prompt a transaction. MetaMask will display full details including contract interactions and gas cost.

5. Sign each transaction only after verifying the exact function call and amount. Malicious dApps may attempt to drain funds through fake approvals.

Security Best Practices

1. Enable biometric authentication (fingerprint or face recognition) in the app settings to add an extra layer of protection each time you open MetaMask.

2. Regularly update the app to the latest version to benefit from security patches and feature improvements released by the MetaMask team.

3. Avoid using public Wi-Fi when conducting transactions. Use a personal, secure internet connection to reduce the risk of man-in-the-middle attacks.

4. Never enter your recovery phrase into any website or application. MetaMask will never ask for it after initial setup.

5. Consider using a secondary wallet for interacting with high-risk dApps. This limits exposure of your primary funds.
