In the evolving cryptocurrency landscape, managing stablecoins like Tether (USDT) across different blockchain networks is essential. This guide provides a step-by-step walkthrough for swapping USDT from the TRON-based TRC20 standard to the Ethereum-based ERC20 standard using Keepbit on the Trust Wallet platform.
Understanding TRC20 vs. ERC20 USDT
TRC20 USDT operates on the TRON blockchain, offering:
- Lower transaction fees (paid in TRX)
- Faster transaction times
- Ideal for cost-sensitive transfers
ERC20 USDT operates on the Ethereum blockchain, featuring:
- Broader compatibility with Ethereum dApps and exchanges
- Higher transaction fees (paid in ETH)
- Preferred for Ethereum ecosystem interactions
👉 Compare current TRC20 vs. ERC20 transaction fees
Prerequisites for the Swap
Before beginning, ensure you have:
- Trust Wallet installed and set up
- USDT TRC20 balance in your Trust Wallet
- TRX tokens for TRC20 transaction fees
- ETH balance for ERC20 gas fees
Step-by-Step Swap Process
1. Access Keepbit via Trust Wallet
- Open Trust Wallet and navigate to the DApp browser
- Enter Keepbit's official URL (verify for authenticity)
- Connect your Trust Wallet to the platform
2. Configure Your Swap
- Select USDT TRC20 as the "Send" currency
- Enter the amount you wish to swap
- Select USDT ERC20 as the "Receive" currency
3. Execute the Transaction
- Review the exchange rate and slippage tolerance
- Confirm the transaction in Trust Wallet
- Wait for TRON network confirmation (typically 2-5 minutes)
4. Receive ERC20 USDT
- After TRC20 transaction confirmation, Keepbit initiates the ERC20 transfer
- Confirm Ethereum transaction if prompted (requires ETH for gas)
- Your ERC20 balance will update upon Ethereum confirmation
Cost Considerations
Transaction costs involve:
- TRC20 network fee (~1-5 TRX)
- Ethereum gas fee (variable, check current rates)
- Keepbit service fee (typically 0.1%-0.5%)
👉 Check current Ethereum gas prices
Security Best Practices
- Always verify Keepbit's official URL
- Start with a small test transaction
- Never share your seed phrase
- Enable biometric authentication in Trust Wallet
FAQ Section
Q: How long does the swap typically take?
A: The complete process usually takes 5-15 minutes, depending on network congestion.
Q: Can I reverse the swap (ERC20 to TRC20)?
A: Yes, the same process works in reverse - simply select ERC20 as the input and TRC20 as the output.
Q: Why do I need both TRX and ETH?
A: TRX pays for the TRC20 transaction, while ETH covers the ERC20 gas fees on Ethereum.
Q: What if my transaction gets stuck?
A: Check the transaction hash on Tronscan (TRC20) or Etherscan (ERC20). Most transactions complete automatically, but you may need to adjust gas fees if stuck.
Q: Are there minimum swap amounts?
A: Yes, minimums vary by platform - Keepbit typically requires at least $20 equivalent.
