Understanding USDT.e and Its Role on Avalanche
The Avalanche Bridge (AB) has replaced the older Avalanche-Ethereum Bridge (AEB), marking a significant upgrade in cross-chain interoperability. The AEB is now fully deactivated, meaning any assets still sitting on it are no longer transferable. To maintain functionality within the Avalanche ecosystem — including platforms like Cryptorefills — users must migrate their assets to the new AB.
One key change introduced by the AB is the naming convention: bridged tokens now carry a “.e” suffix, indicating they originate from the new bridge. For example:
- Legacy USDT (from AEB) → Now deprecated
- New USDT.e (from AB) → Current standard
This applies not just to USDT but to all ERC20 tokens moved via the AB. So if you previously held USDT on Avalanche through AEB, those tokens are no longer usable unless upgraded.
Why USDT.e Offers a Better Experience
Migrating to USDT.e isn’t just about staying current — it brings tangible benefits:
- Faster transaction confirmations
- Lower gas fees
- Improved security and reliability
- Full compatibility with dApps and payment platforms like Cryptorefills
By aligning with the new bridge, users gain access to a more efficient and scalable network designed for everyday transactions.
How to Convert Deprecated USDT to USDT.e
If you still hold legacy USDT on the deprecated AEB, follow these steps to upgrade to USDT.e using the official Avalanche Bridge interface.
Step 1: Access the Avalanche Bridge
Visit the official bridge portal: https://bridge.avax.network/convert/
Connect your wallet — MetaMask is fully supported and recommended.
Make sure your wallet is set to the Avalanche network (C-chain) before proceeding.

Step 2: Select USDT for Upgrade
Once connected:
- Click the “Upgrade tokens” button at the top.
- Choose USDT from the list.
- You’ll be redirected to the USDT-specific conversion page:
https://bridge.avax.network/convert/USDT - The system will auto-detect your available balance. Verify that the amount displayed matches your wallet holdings.
You can choose to convert the full amount or specify a partial value.
Step 3: Initiate the Upgrade Process
Click the “Upgrade” button at the bottom of the page. This triggers the first step in a two-part transaction process.
You'll be redirected to a status screen while the system prepares your upgrade.
Step 4: Approve Asset Upgrade in MetaMask
A MetaMask pop-up will appear asking for permission to allow Avalanche to upgrade your USDT tokens.
- Review the transaction details.
- Confirm gas fees.
- Click “Confirm” to proceed.
After confirmation, you’ll return to the bridge status page, which will show “Waiting for confirmation.”
Step 5: Approve Token Conversion
While the status remains “Waiting,” a second MetaMask prompt will appear — this time requesting approval to convert your USDT into USDT.e.
- Carefully review the gas fee and total amount.
- Click “Confirm” again.
This second transaction finalizes the migration from legacy USDT to USDT.e.
Step 6: Add USDT.e to Your Wallet
Finally, a third MetaMask notification will ask if you want to add USDT.e to your wallet.
Click “Add Token” so that your wallet recognizes the new token balance automatically.
✅ You’ve successfully migrated your deprecated USDT to USDT.e!
Your funds are now compatible with all Avalanche-based applications, including Cryptorefills.

Frequently Asked Questions (FAQ)
Q: Is USDT.e the same as regular USDT?
A: While both represent a 1:1 USD-pegged stablecoin, USDT.e is specifically bridged via the new Avalanche Bridge and only usable on Avalanche’s C-Chain. Regular USDT on Ethereum or legacy AEB cannot be used interchangeably.
Q: Can I send USDT.e back to Ethereum?
A: Yes, but you must use the Avalanche Bridge to “debridge” it back to Ethereum’s ERC20-USDT. Direct transfers may result in permanent fund loss.
Q: What happens if I don’t upgrade my old USDT?
A: Deprecated AEB tokens cannot be transferred or used in current dApps. They remain stuck until migrated via the upgrade process.
Q: Are there high fees when converting to USDT.e?
A: Gas fees on Avalanche are typically under $1, making the conversion cost-effective compared to Ethereum’s network costs.
Q: Does Cryptorefills support other .e tokens?
A: Yes — other AB-migrated tokens like DAI.e and ETH.e are also accepted when paying via Avalanche.
Q: Can I use MetaMask Mobile for this process?
A: Absolutely. The entire conversion flow works seamlessly on both desktop and mobile versions of MetaMask.
