How to Store and Use USDT and USDC in a Crypto Wallet
USDT and USDC are widely used for holding funds and making crypto transfers. But before sending them for the first time, there are a few things worth understanding: why the same token exists on different networks, how to choose the correct address, and why you might need another cryptocurrency to cover transaction fees.
In this guide, we'll explain how it all works and how to receive, store, and send USDT and USDC with IronWallet.
Where Are USDT and USDC Stored?
USDT and USDC are stablecoins designed to maintain a value close to one US dollar. USDT is issued by Tether, while USDC is issued by Circle. Both allow users to hold and transfer crypto without the sharp price swings often seen in Bitcoin and many other cryptocurrencies, although their value can still move above or below $1.
The tokens themselves aren't stored inside the wallet app. Balance and transaction data are recorded on the blockchain, while your wallet lets you manage your assets using private keys.
IronWallet is a non-custodial wallet. When you create a new wallet, your private keys are generated and stored locally on your device. We don't have access to them, and they are never stored on IronWallet servers. Standard transactions are signed directly on your device.
To keep access to your wallet, store your recovery phrase securely and never share it with anyone.
Why Do You Need to Choose a Network for USDT and USDC?
USDT and USDC are available on multiple blockchain networks. For example:
USDT is available on Ethereum (ERC-20), TRON (TRC-20), BNB Smart Chain (BEP-20), and other networks.
USDC is available on Ethereum, Solana, Base, and several other blockchains.
This means choosing USDT or USDC alone isn't enough. You also need to make sure the sender and recipient are using compatible networks and the correct token.
Let's say you want to receive USDT on TRON. The sender needs to select the TRON network, and your wallet must support USDT on that network.
If the sender chooses Ethereum instead, the tokens will be sent on Ethereum, not TRON. A regular transaction doesn't automatically move assets between blockchains.
There's another detail that's easy to miss: Ethereum and BNB Smart Chain addresses can look identical, often starting with 0x. But matching address formats don't mean you can use either network.
Some networks also have different versions of the same stablecoin, such as USDC and USDC.e. These shouldn't be treated as automatically interchangeable.
Before sending crypto, always check the exact token, network, and recipient address. A mistake in any of these details could make your funds inaccessible.
How to Receive USDT or USDC in IronWallet
If you've already created your wallet, receiving stablecoins takes just a few steps.
Open IronWallet and select USDT or USDC on your preferred supported network.
Tap Receive to display your receiving address and QR code.
Copy the address and share it with the sender, or enter it when withdrawing funds from another platform.
Make sure the sender uses the same network and selects the correct token.
Once the transaction is confirmed on the blockchain, the funds will appear under the corresponding asset balance in IronWallet.
If you're sending a large amount to a new address for the first time, consider making a small test transfer, taking any fees and minimum transfer amounts into account.
How to Send USDT or USDC
To send funds, open the token you want to transfer in IronWallet and tap Send.
Enter the recipient's address and the amount. Before confirming, check the selected network, destination address, and transaction fee.
But there's one important detail.
Let's say you have 500 USDT in your wallet and want to send 100 USDT. On some blockchains, a standard transfer may require another cryptocurrency to complete the transaction.
That's because of network fees.
On Ethereum, fees are typically paid in ETH. On BNB Smart Chain, they're paid in BNB, while Solana uses SOL. TRON uses network resources called Energy and Bandwidth, and TRX may be consumed if those resources are insufficient.
In other words, USDT or USDC is the asset you're sending, but the blockchain requires resources to process the transaction.
How IronWallet Lets You Send USDT and USDC Without a Separate Gas Token
IronWallet supports gasless transfers for eligible tokens and networks.
This feature lets you send supported assets without first buying ETH, TRX, BNB, or another native cryptocurrency just to cover network fees.
For example, eligible USDT transfers on Ethereum or TRON can be completed without maintaining a separate ETH or TRX balance. Similar functionality is available on other supported networks.
However, gasless doesn't mean there are no fees. For supported transactions, fees can be paid using the token you're sending. Availability and final costs depend on the asset, network, and specific transaction.
This removes the extra step of buying another cryptocurrency solely to pay for gas. IronWallet displays the transaction details before confirmation, so you can review the cost.
Can You Swap USDT or USDC Directly in IronWallet?
Yes. Besides storing and sending stablecoins, IronWallet lets you exchange supported assets through its built-in Swap feature.
For example, you can select USDT as the asset you want to swap and BTC or ETH as the asset you want to receive.
Simply enter the amount, select an available trading pair, and review the quoted rate, estimated amount you'll receive, and applicable fees.
IronWallet uses integrated swap infrastructure with access to multiple liquidity sources. It also supports cross-chain swaps when a suitable route is available for the selected assets.
Everything is handled through the IronWallet interface, so you don't need to find separate services to complete a supported swap.
This means you can receive, store, send, and swap USDT and USDC in one wallet while keeping control of your private keys.
