MetaMask Mobile is a non-custodial software wallet for iOS and Android that brings account management, a built-in dApp browser, WalletConnect support, and in-app swaps to your phone. If you want to know how to use MetaMask Mobile for daily DeFi actions — from swapping tokens to connecting to lending or staking dApps — this guide covers setup, syncing with desktop, Ledger pairing, and practical safety tips based on hands-on usage.
Who this wallet is best for
Who should look elsewhere
A short walkthrough for new users (how to use MetaMask Mobile, installation guide):
Practical notes: the onboarding flow will ask you to confirm at least part of your seed phrase. If you ever need to restore, see /import-and-restore-wallet and /seed-phrase-backup-recovery.
For a longer installation and account creation walkthrough, refer to /install-create-wallet and /mobile-app-setup.
Syncing with the browser extension
MetaMask Mobile + Ledger (how to use MetaMask Mobile Ledger)
Security trade-off: hardware pairing keeps private keys offline, but pairing over Bluetooth introduces a surface you should be aware of (firmware and app updates reduce risk).
Which should you use? The in-app browser injects the provider directly so connecting is a one-tap action inside MetaMask. WalletConnect works from external browsers (Chrome on Android, Safari on iOS) by creating a secure session between the website and your app. Which to choose depends on the workflow.
How to use MetaMask on Android Chrome (step-by-step)
If you prefer not to leave the MetaMask environment, open the dApp within the MetaMask in-app browser instead. In my experience the in-app browser reduces deep-link glitches (but always double-check the URL). See /connect-to-dapps-walletconnect for more.
MetaMask primarily supports EVM-compatible blockchains. To add a network (for example adding BSC to MetaMask mobile), go to Settings > Networks > Add Network and paste the RPC details, chain ID, and currency symbol. If you need step-by-step parameters for common chains, see /add-bsc-to-metamask, /add-polygon-to-metamask, and /add-avalanche-to-metamask.
A practical tip: every network uses its own gas token. If you switch to BSC and try to send BEP-20 assets without BNB for gas, the transaction will fail. Always confirm the native token required for gas on the network you add.
MetaMask Mobile offers an in-app swap feature that aggregates multiple liquidity sources and shows route options, estimated slippage, and gas estimates before you confirm. Typical swap flow: Assets > Swap > Select tokens > Review quotes and fees > Confirm.
When interacting with DeFi dApps (Uniswap-style swaps, lending platforms, liquid staking), MetaMask acts as the signer. That means you approve token allowances to the dApp's smart contracts, then sign transactions. I believe checking allowance amounts and using moderate slippage settings (0.5–1% for common tokens, higher for low-liquidity trades) reduces risk. For step-by-step swap and router explanations see /in-wallet-swap-guide and for staking via dApps see /staking-via-dapps-from-metamask.

Q: Is it safe to keep crypto in a hot wallet?
A: Hot wallets are convenient for daily activity but carry more attack surface than cold storage. For small, frequently used balances a hot wallet is pragmatic. For long-term large holdings use a hardware wallet or split funds across storage solutions.
Q: How do I revoke token approvals?
A: Check the wallet's permissions list or use a reputable approval-revoke tool while connected with MetaMask. Review allowances before approving unlimited access. See /how-to-revoke-approvals-step-by-step and /token-allowances-and-revoke.
Q: What happens if I lose my phone?
A: If you have your seed phrase (or an encrypted cloud backup), you can restore on a new device. If not, the funds are effectively inaccessible. Immediately rotate any accounts where keys were exposed and revoke sessions where possible.
MetaMask Mobile is a practical hot wallet for daily DeFi interactions, with the convenience of an in-app browser, WalletConnect support, and the option to pair hardware wallets like Ledger. It strikes a balance between usability and control, though it requires careful backup and approval hygiene. If you want guided setup steps or deeper troubleshooting, start with /install-create-wallet, then see /sync-and-use-on-multiple-devices and /ledger-with-metamask-guide to add a hardware layer.
