USDT Explained: A Complete Guide to Tether and How It Works

·

Tether (USDT) is one of the most widely used cryptocurrencies in the digital asset ecosystem. As a stablecoin, it plays a crucial role in bridging the volatility of traditional cryptocurrencies like Bitcoin and Ethereum with the stability of fiat currencies—specifically, the U.S. dollar.

With over 9,900 cryptocurrencies listed on major platforms such as CoinMarketCap and CoinGecko—and many more unlisted—the crypto space is vast and diverse. These digital assets are categorized based on their function and underlying infrastructure. Common categories include decentralized finance (DeFi), non-fungible tokens (NFTs), utility tokens, and stablecoins, among others.

What Are Stablecoins?

Stablecoins are digital currencies designed to maintain a stable value by being pegged to reserve assets like the U.S. dollar, euro, or gold. This makes them ideal for transactions, savings, and trading without exposure to extreme price swings.

Popular examples of stablecoins include:

Among these, Tether (USDT) stands out due to its early market entry, wide adoption, and high liquidity across exchanges.

What Is Tether (USDT)?

Tether (USDT) is a blockchain-based cryptocurrency that operates as an Ethereum token but is also available on multiple other networks. It is pegged 1:1 to the U.S. dollar, meaning each USDT should theoretically be worth exactly $1.

According to Tether Limited, the company behind USDT, every issued token is backed by equivalent reserves, including cash, cash equivalents, and short-term deposits. While this claim has faced scrutiny in the past, USDT remains one of the most trusted and heavily traded stablecoins globally.

Different Types of USDT Based on Blockchain Networks

One key detail users must understand is that USDT exists on multiple blockchains, each with its own unique address format and transaction fees. Choosing the correct network during transfers is critical—using the wrong one may result in permanent loss of funds.

Here are the most common USDT variants:

💡 Pro Tip: Always verify the recipient’s supported network before sending USDT. For example, if you send ERC20 USDT to a wallet that only accepts TRC20, the funds may be lost.

How to Get a USDT Wallet

You don’t need a standalone wallet just for USDT. Most cryptocurrency exchanges and digital wallets support multiple versions of USDT across various chains.

To illustrate, let’s use a typical exchange interface:

  1. Log into your account.
  2. Navigate to Wallet > Spot.
  3. Click Deposit.
  4. Search for USDT.
  5. Select the desired network (e.g., TRC20 or ERC20).
  6. Copy the generated deposit address.

For example:

Each network has its own unique address format. Never reuse addresses across chains.

How to Fund Your USDT Wallet

There are several ways to acquire USDT. The two most common methods are:

1. Offline Merchant Purchase

You can buy USDT directly from a trusted local or online crypto dealer. After agreeing on a price, you make a bank transfer or cash payment, and the merchant sends the equivalent amount of USDT to your wallet.

While convenient, this method carries counterparty risk. Always deal with verified sellers and avoid sharing sensitive personal information.

2. Peer-to-Peer (P2P) Trading

P2P platforms connect buyers and sellers directly while using an escrow system to prevent fraud. When you initiate a purchase, the platform holds the seller’s USDT until you confirm payment.

Steps to Buy USDT via P2P:

  1. Go to P2P Trading on your exchange.
  2. Select USDT as the cryptocurrency.
  3. Filter offers by amount or payment method.
  4. Review seller metrics: trade volume, completion rate, and preferred payment options.
  5. Click Buy USDT.
  6. Enter the fiat amount (e.g., ₦10,000).
  7. Make the payment to the seller’s provided bank details.
  8. Confirm payment in the app.
  9. Once confirmed, the platform releases USDT to your P2P wallet.
⚠️ Never send money to a different account than the one displayed. Scammers often try to redirect payments.

How to Transfer USDT from P2P to Spot Wallet

After purchasing USDT via P2P, it resides in your Funding/P2P wallet. To use it for trading or withdrawals, transfer it to your Spot wallet:

  1. Go to Wallet > Funding.
  2. Click Transfer.
  3. Set “From” as P2P Wallet and “To” as Spot Wallet.
  4. Select USDT and confirm the transfer.

The balance will appear in your Spot wallet within seconds.

How to Withdraw USDT to Another Wallet

Withdrawing USDT requires careful attention to three key details:

Step-by-Step Withdrawal:

  1. Click Withdraw.
  2. Search for USDT.
  3. Paste the recipient address (e.g., TFMXMmevDiAvZyEsy4jvQgKi5UsgntmX8e).
  4. Select the correct network (TRC20 in this case).
  5. Enter the amount (e.g., $1).
  6. Confirm and authenticate using your 2FA method (SMS, email, or Google Authenticator).

Once confirmed, the transaction is processed on-chain.
