Tether (USDT) operates primarily on two major smart contract standards: USDT ERC20, based on the Ethereum blockchain, and USDT TRC20, which operates on the Tron network. Each has distinct characteristics, especially regarding transaction costs. Ethereum-based transfers typically incur higher fees, often around 10 USDT or more, while Tron transactions usually cost just 1 USDT. This makes TRC20 a popular choice for moving funds between exchanges, wallets, and decentralized applications.
However, when using Trust Wallet—a versatile decentralized wallet supporting over a thousand cryptocurrencies—you may notice that not all USDT variants are directly swappable. Understanding these differences is key to managing your assets effectively.
Understanding USDT Variants in Trust Wallet
When you search for USDT in Trust Wallet, several options appear:
- Tether ERC20 (Ethereum blockchain)
- Binance-Peg Tether USD BEP20 (Binance Smart Chain)
- (PoS) Tether USD Polygon (Polygon network)
- USDTBEP2 BEP2 (Binance Chain)
Notably, USDT TRC20 (Tron) only supports send and receive functions. It cannot be swapped directly within the wallet for other cryptocurrencies like BNB, BUSD, or Smart Chain tokens.
Why You Can’t Convert USDT TRC20 to Smart Chain
Trust Wallet does not natively support the Tron blockchain, which is why swapping USDT TRC20 to other coins isn’t possible. This limitation exists partly because TRON’s negligible transaction fees offer less incentive for exchanges and wallets to integrate swap functionalities, as their revenue models often rely on gas fees.
Step-by-Step: Converting USDT BEP20 to Smart Chain
For users holding USDT BEP20, the process to convert to Smart Chain (BNB) is straightforward using Trust Wallet’s built-in DEX (decentralized exchange).
- Open Trust Wallet and navigate to the DEX tab at the bottom.
- Ensure you select USDT BEP20 as the ‘You Pay’ asset (top section).
- Choose BNB Smart Chain as the ‘You Receive’ asset (bottom section).
- Click Approve to authorize the transaction. Wait for confirmation.
- Once approved, click Swap. You can adjust the amount using the percentage options (25%, 50%, 75%, 100%) or enter a value manually.
- Confirm the swap. Your USDT BEP20 will be converted to BNB Smart Chain.

Converting Other USDT Types to Smart Chain
USDT BEP2 to BNB Smart Chain
Since Binance Coin (BNB) and Binance Smart Chain are distinct, converting USDT BEP2 requires a two-step process:
- First, swap USDT BEP2 to BNB using the DEX.
- Then, convert the BNB to BNB Smart Chain.
The procedure is identical to the standard swap: approve the transaction, then execute the swap.
USDT Polygon (PoS) to MATIC and Then to Smart Chain
If you hold USDT on the Polygon network, you must first convert it to MATIC:
- In the DEX, select USDT Polygon as the input and MATIC as the output.
- Approve and swap.
- Once you have MATIC, you can then swap MATIC to BNB Smart Chain.
Always remember to approve each asset before swapping.
Best Practices and Tips
- Always verify you are using the correct USDT variant (BEP20 for direct swaps to Smart Chain).
- Ensure sufficient BNB balance to cover transaction gas fees on the Binance Smart Chain.
- Double-check addresses and network types before initiating any transfers or swaps.
- If you are new to cryptocurrency, consider seeking guidance or using trusted resources to avoid errors.
Frequently Asked Questions
Why can’t I see USDT TRC20 in my Trust Wallet?
Trust Wallet supports USDT TRC20 for sending and receiving but does not allow swaps because it lacks native support for the Tron blockchain. You can still store and transfer TRC20 tokens.
What is the difference between USDT BEP20 and BEP2?
USDT BEP20 exists on the Binance Smart Chain, while BEP2 is on the Binance Chain. They are different networks, and assets must be converted appropriately when moving between them.
Can I convert USDT ERC20 to Smart Chain directly in Trust Wallet?
No, you must first bridge USDT ERC20 to the Binance Smart Chain (converting it to USDT BEP20) using a cross-chain bridge or an exchange before swapping to Smart Chain within Trust Wallet.
Why do I need to approve a token before swapping?
Approval is a security step that authorizes the smart contract to access and swap a specific amount of your tokens. It only needs to be done once per token.
Are there high fees for converting USDT to Smart Chain?
Fees depend on network congestion but are generally lower on BSC compared to Ethereum. You’ll pay a gas fee in BNB for the transaction.
What should I do if my swap fails?
Ensure you have enough BNB for gas, that you’ve approved the token, and that you are using a compatible USDT version (like BEP20). Retry the transaction with a slightly higher slippage tolerance if needed.
Conclusion
Converting USDT to Smart Chain on Trust Wallet is efficient if you hold a compatible type like USDT BEP20. Use the DEX feature, select the correct assets, approve the transaction, and execute the swap. For other USDT variants like TRC20 or ERC20, first convert them to a BSC-supported asset via a bridge or exchange. Always prioritize verifying networks and having enough gas fees for successful transactions. 👉 Get advanced methods for managing multi-chain assets
