How to Set Up and Use a Mobile Crypto Wallet

· 5 min read

If, for some reason, it’s inconvenient for you to use a browser extension wallet like MetaMask, you can always download a mobile wallet, which has nearly the same functionality.
With it, you’ll still be able to interact with different networks, swap tokens, and work with the entire crypto ecosystem and its tools.

All wallets that I’ve personally tested and consider reliable are listed in Tools → Wallets on our platform.
There, you’ll find links to multi-currency, single-currency, and specialized wallets with unique features — all explained in detail as the training progresses.

Setting Up a Mobile Wallet​

This is one of the best options for interacting with DeFi and the Web3 ecosystem.
The wallet is available for both Android and iPhone.

All you need to do is:

  1. Find it in the App Store or Google Play.
  2. Download and install it.
  3. Always use verified links from the course description — there are many scam apps pretending to be real wallets.

I already have the wallet installed. The setup process is simple — you have two options:

  • Create a new wallet
  • Import an existing one

In my case, I choose Create, accept the terms, pick an interface color (any will do), and give my wallet a name — e.g., Main. Then I press Create.

✅ That’s it — the wallet is created.

Securing Your Seed Phrase​

Next, the wallet shows your seed phrase (also called a mnemonic phrase).

You must:

  • Write it down on paper and keep it in a safe place.
  • Never take screenshots or store it online.
  • Without it, you won’t be able to recover your funds if your phone is lost or the app is deleted.

Press Continue, set a password, confirm it, and enable Face ID (optional).
Now your wallet is ready to use.

Supported Networks​

The mobile wallet includes major networks by default:

  • Ethereum Mainnet
  • Polygon
  • Optimism
  • Arbitrum
  • Gnosis
  • Fantom

You can switch between them instantly.
In my case, I’m interested in the Avalanche network, so I select it.

💡 Your wallet address remains the same across all EVM-compatible networks — Ethereum, Avalanche, Polygon, and others.

Why I Chose 1inch Wallet​

I use the 1inch Wallet because it supports most major blockchains for Web3 and DeFi.
Its key advantage is the integrated 1inch aggregator, which allows:

  • Instant swaps between tokens
  • Minimal fees
  • Best exchange rates automatically selected across DeFi protocols

For example, if you want to exchange AVAX to USDT, the wallet will automatically find the most profitable route across DEXs.

The app has two main tabs:

  1. Home — for balance, Receive, and Send buttons.
  2. Swap — for token exchanges.

Other features are explained in later modules.

Example: Sending AVAX to Your Mobile Wallet​

Now I’ll transfer some Avalanche (AVAX) tokens from my Core Wallet to the 1inch mobile wallet.

  1. Press Send in Core Wallet.
  2. Paste the 1inch wallet address.
  3. Double-check the last 3 characters of the address (e.g., …566).
  4. Enter 0.2 AVAX and confirm the transaction.

After a few minutes, the AVAX balance appears in the 1inch wallet, showing both the token amount and its USD equivalent.

Working with Multiple Wallets​

With 1inch Wallet, you can do everything you would with MetaMask or Core Wallet:
buy crypto, withdraw it, and interact with DeFi tools — all from your phone.

The only limitation: it doesn’t support the native Bitcoin network.
(Core Wallet and MetaMask can, but 1inch Wallet cannot.)

You can also create additional wallets inside the app:

  • Tap the “➕” button to add a new wallet.
  • Give it a name and manage it in settings.

This helps you separate wallets by purpose — for example:

  • One for portfolio investing
  • Another for DeFi activities

To switch between wallets, simply swipe left or right.

Example: Managing and Transferring Between Wallets​

Let’s say I mistakenly sent 10 USDT to my second wallet instead of the first.
To fix this, I’ll:

  1. Transfer a small amount of AVAX to the second wallet to cover gas fees.
  2. Send the USDT back to my main wallet.

In the app, I can easily switch wallets.
Once the AVAX arrives, I:

  • Copy my main wallet address.
  • Open the second wallet → press Send → paste the address.
  • Select USDT and confirm.

In 1inch Wallet, USDT appears automatically — no need to manually import token contracts.
The transaction confirms, and the funds return to my main wallet.

Swapping Tokens Inside the App​

Now I’ll open the built-in Swap tab and exchange USDT for Avalanche.

Steps:

  1. The first transaction is a Permit — it authorizes the smart contract to use your tokens.
  2. Then, confirm the Swap.

✅ Done — the exchange is complete.
Now my balance shows Avalanche (AVAX) instead of USDT.

Summary​

With the 1inch Wallet, you get:

  • Built-in swap aggregator (best rates, lowest fees)
  • Multi-chain support for all major EVM networks
  • Full control of your assets on mobile
  • Ability to manage multiple wallets in one app

It’s one of the most convenient and powerful wallets for working with the Web3 ecosystem and DeFi tools — directly from your smartphone.
