Here’s how the MetaMask App Works!

Step 1: Install the App

This is the first step, where the users install the mobile app via their official app store, such as the Apple Store and the Google Play Store.

Step 2: Create or Import a Wallet

In this step, the users can create their own wallet or can effectively import the complete wallet. This is a straightforward process, whether you are using a desktop browser or the mobile app; it is a simple process.

Step 3: Generate the Secret Recovery Phrase

It is a human-readable master key that mathematically drives where the user’s generated key is backed up. Under this step, your app will generate a 12- to 24-word sequence from a standardized dictionary.

Step 4: Connect to the Blockchain Network

Under this step, you can connect your app to a blockchain network such as MetaMask. You need to use a Remote Procedure Call (RPC) node.

Step 5: Generate Wallet Address

In this step, MetaMask generates a wallet address with the help of cryptographic derivation. This app generates a deterministic process rather than randomly assigning one.

Step 6: Broadcast the Transaction

This app broadcasts the transactions locally by securely signing the transaction payload with a simple private key.

This is how the complete MetaMask app works. Now, if you are not clear about what type of app to build, whether a custodial or non-custodial wallet, the following section will state it all.

Custodial vs Non-Custodial Wallets: The First Decision You Make
