Crypto for beginners, part 3: buying, swapping and using cryptocurrency with IronWallet

In the first two parts of Crypto for Beginners, we explained how blockchain and cryptocurrency work and introduced crypto wallets, private keys, recovery phrases, and transactions.

Now let's move from theory to practice.

How do you buy cryptocurrency? How do you swap one token for another? What are network fees? And how can you use a non-custodial wallet such as IronWallet to manage your crypto?

How to buy cryptocurrency

One of the easiest ways for beginners to enter the crypto world is to buy cryptocurrency with traditional money, such as USD or EUR.

Depending on your location and the available payment providers, you may be able to purchase crypto using a bank card, bank transfer, or another supported payment method.

IronWallet integrates third-party crypto payment providers that allow users to purchase cryptocurrency. The exact payment methods, fees, limits, and supported assets depend on the provider and the user's location.

When buying crypto, always check:

• which cryptocurrency you are purchasing;

• which blockchain network it uses;

• the exchange rate;

• applicable fees;

• where the purchased cryptocurrency will be delivered.

Buying cryptocurrency and storing it are two different processes. A payment provider processes the purchase, while your wallet gives you access to and control over your crypto assets.

How to receive cryptocurrency in IronWallet

Receiving cryptocurrency is straightforward.

Your wallet has a public blockchain address that you can share with another person or service.

In IronWallet, you can select the cryptocurrency you want to receive and view the corresponding wallet address.

The sender then uses this address to make the transaction.

Before accepting a transfer, always check the network. The sender must use a network supported by the receiving address and asset.

For example, USDT can exist on several blockchain networks. Sending USDT over the wrong network can cause problems accessing the funds.

A simple rule for beginners:

Check the asset. Check the network. Check the address. Then send.

How to send cryptocurrency

Sending crypto works in the opposite direction.

In IronWallet, you select the asset, enter the recipient's address, specify the amount, review the transaction details, and confirm the transaction.

The wallet signs the transaction, which is then broadcast to the blockchain network.

The network verifies the transaction and includes it in the blockchain.

Remember that a confirmed blockchain transaction cannot be canceled or reversed. If you send cryptocurrency to the wrong address, the blockchain cannot return it. The only way to recover the funds is if you know the recipient and they send the cryptocurrency back to you.

For this reason, always check the recipient address before confirming a transaction.

What is a crypto swap?

A crypto swap is the exchange of one cryptocurrency or token for another.

For example:

ETH → USDT

or

BTC → another supported asset

Instead of selling one cryptocurrency for fiat currency and then buying another asset, a swap allows you to exchange supported crypto assets directly.

IronWallet supports crypto swaps for supported assets and networks, allowing users to exchange cryptocurrencies from their wallet.

Before confirming a swap, check:

• the asset you are selling;

• the asset you will receive;

• the exchange rate;

• the network fee;

• the amount you will receive.

The available assets, rates, and fees can change depending on market conditions and the liquidity providers used for the swap.

What are crypto network fees?

Blockchain transactions usually require a network fee.

These fees are paid to the blockchain network for processing transactions. They are not simply a fee charged by the wallet.

The amount depends on the blockchain and its current network conditions.

For example, Ethereum transactions use ETH for gas fees. Other networks use their own native assets.

Some networks and transactions can also support gasless or sponsored transactions, where the user does not have to provide the native network token for the gas fee.

IronWallet supports gasless sending for selected assets and networks, including Ethereum, BNB Smart Chain, Polygon, Solana, Base, Arbitrum, and Optimism, where available.

This can make sending certain cryptocurrencies easier for beginners who do not hold the network's native token.

What are stablecoins?

A stablecoin is a cryptocurrency designed to maintain a relatively stable value, usually by being linked to a fiat currency such as the US dollar.

Two well-known examples are USDT and USDC.

Stablecoins are widely used for transferring value, trading, and moving funds between different crypto services.

However, there is an important detail beginners should understand:

The same stablecoin can exist on different blockchain networks.

For example, USDT can be available on Ethereum, Tron, Solana, and other networks.

USDT is not simply one universal blockchain asset. The network is part of the transaction.

When sending or receiving stablecoins in IronWallet, always make sure that the selected network matches the network used by the recipient or service.

What else can you do with cryptocurrency?

Once you understand the basics of buying, receiving, sending, and swapping crypto, you can explore other parts of the blockchain ecosystem.

Depending on the network and supported services, cryptocurrency can be used for:

• payments;

• transferring money;

• swapping tokens;

• interacting with decentralized applications (dApps);

• participating in DeFi;

• staking;

• purchasing NFTs and other digital assets.

You don't need to use all of these features at once.

For a beginner, it is better to first understand basic transactions and wallet security before exploring more advanced blockchain applications.

Why use a non-custodial wallet?

IronWallet is a non-custodial crypto wallet, which means users maintain control of their wallet and private keys.

This gives you more control over your assets, but it also means that you are responsible for protecting your recovery phrase and private keys.

IronWallet does not need to hold your funds on your behalf.

Your cryptocurrency remains recorded on the relevant blockchain, while the wallet provides the tools needed to manage your assets and interact with the network.

Basic rules for using crypto safely

Before confirming any transaction in IronWallet or another crypto wallet, follow a few simple rules:

Check the address.
Make sure the recipient's address is correct.

Check the network.
Make sure you are using the correct blockchain for the asset.

Check the amount.
Review the amount before signing the transaction.

Check the fee.
Make sure you understand the applicable network or service fee.

Protect your recovery phrase.
Never share your recovery phrase or private keys with anyone.

Be careful with unfamiliar services.
Do not connect your wallet to websites or dApps you do not understand.

What have we learned?

Using cryptocurrency does not have to be complicated.

The basic process is:

Buy → store → receive → send → swap → explore

A non-custodial wallet such as IronWallet gives you one place to manage supported cryptocurrencies and interact with different blockchain networks.

The most important thing for a beginner is not learning every crypto feature at once. Start with the basics, understand how transactions work, always check the network and address, and protect your recovery phrase.

In Part 4, we will take a closer look at how to use IronWallet safely, including creating or importing a wallet, receiving and sending cryptocurrency, checking networks, and protecting your wallet from common mistakes.
