How to Set Up a MetaMask Wallet on a Mobile Phone
You will need to install MetaMask on your Android or iPhone from Google Play and App Store, respectively.

Securing Your Metamask Wallet: SRP, Private Keys and Self-Custodianship
Secret Recovery Phrases
Secret recovery phrases (SRP) are an important security layer that gives you access to your crypto wallet. Most crypto wallets use 12-word SRP and 24-word SRP.
Unlike your Facebook or Instagram account, you cannot reset your password by simple means of email or mobile authentication. MetaMask cannot help you recover your password in case you lose or forget your wallet password.
This is where SRP comes in handy. Users require their SRP to set up a new password, restore wallets, and validate ownership. As long as you have your SRP, you can always uninstall your MetaMask wallet from any device and restore it on another device.
You must secure your SRP. If someone knows the SRP in your wallet, they will have complete access to the cryptocurrencies and NFTs held in that wallet.
Private Key
Each wallet address has a private key. A private key is uniquely associated with each wallet. It is used to compute a digital signature that verifies the ownership of the wallet and funds held in it during a transaction.
Like the SRP, crypto wallet users must ensure that their private keys are secure and remain a secret.
Although you will not be interacting with private keys directly, it is essential to learn about them. You can find the private keys to your MetaMask wallet under Settings > Security & Privacy > Show Private keys.
Just like the SRP, anyone with your private keys will have full access to your wallet and its funds.
You can use private keys to import any crypto wallet account to your MetaMask wallet.
Self-Custodianship
An important point for all crypto wallet users is that you are the sole custodian of your wallet.
When you use a non-custodial wallet like MetaMask, you alone are responsible for securing your crypto assets held in your wallet. If your wallet gets hacked, recovering your funds will be incredibly difficult.
Remember, MetaMask representatives will never ask for your SRP in any scenario.
How to Use Metamask Wallet
Here are some important information on how to use a MetaMask wallet.
Connecting to Different Blockchains
Your crypto wallet is the gateway to the crypto world. You can use various EVM-compatible blockchain networks from your wallet.
MetaMask sets the Ethereum mainnet as its default blockchain. You can choose between various EVM-compatible blockchains, layer-two blockchains, and test networks, including Polygon, BNB Chain, Avalanche C-Chain, Optimism, Arbitrium, and more.
You cannot use the Bitcoin blockchain from your MetaMask wallet or access other non-EVM-compatible blockchains, such as Solana and Cardano.
Therefore, you cannot hold BTC, SOL, or ADA on a MetaMask wallet.
If you want to hold BTC on your MetaMask wallet, you must buy a wrapped Bitcoin, an EVM-compliant token representing BTC on an EVM chain.
Adding Tokens to Your MetaMask Wallet
You will need your wallet address to send crypto tokens to your MetaMask wallet.
Make sure that you send only tokens that exist natively on EVM-compatible chains to your wallet address.
Your tokens will show up on the ‘Tokens’ tab. If your tokens do not show up, you can search for the token by clicking on the ‘Import tokens’ button.
MetaMask has an ‘enhanced token detection’ feature that can be switched on and off from the settings.
Once you have cryptocurrencies in your MetaMask wallet, you can swap cryptos directly from your wallet home page. Ensure that you hold the native token (ETH, BNB, MATIC) of the blockchain to pay for gas.
MetaMask will search across decentralized exchanges (DEXs) for the most competitive rates. The app charges a service fee of 0.875% on each swap.
Sending Tokens From Your MetaMask Wallet
The most important point to remember while sending tokens from your MetaMask wallet is to ensure that the recipient’s wallet address is correct. Otherwise, your tokens will be lost and will become irretrievable.
Specify the amount you want to send while remembering that the blockchain will charge a gas fee to execute the transaction.
You can also set the amount of gas fee you want to spend depending on network congestion and transaction priority.
Using Decentralized Applications (dApps)
You can access various dApps encompassing decentralized finance (DeFi), blockchain gaming, NFTs, and more with your MetaMask account.
Your MetaMask app will serve as your login to these Web3 websites. As long as you have installed the MetaMask browser extension, you can visit these websites from your PC or laptop.
If you have not installed the MetaMask browser extension on your PC/laptop, you can use WalletConnect to log in using your MetaMask account. This is useful for browsers like Safari that do not support the MetaMask browser extension.
The experience on your smartphone is slightly different. The MetaMask mobile app comes with an inbuilt browser that allows you to log in to Web3 seamlessly.
Ensure that the blockchain that your wallet is connected to is the same one where the dApp exists.
Interesting Features of MetaMask
The Bottom Line
MetaMask is a widely used crypto wallet that lets users securely manage Ethereum and EVM-compatible assets on mobile and desktop. Setting it up requires saving a 12-word recovery phrase and keeping private keys secure, as MetaMask is self-custodial, which means only the user controls wallet security.
With features like token swaps, staking and bridges, MetaMask provides a smooth entry into the Web3 ecosystem. However, users must be careful: losing the recovery phrase or exposing private keys can result in permanent loss of funds.
