The integration of Tether (USDT) on Polkadot’s ecosystem marks a significant milestone for decentralized finance (DeFi) within the network. With USDT now available as a native asset on Polkadot Asset Hub—formerly known as Statemint—users can seamlessly transfer stablecoins across one of the most secure and scalable multi-chain platforms. This guide walks you through the step-by-step process of transferring USDT using the Polkadot-JS UI, while highlighting key considerations, security practices, and network-specific nuances.
Whether you're a developer, power user, or DeFi enthusiast, understanding how to interact directly with the Polkadot blockchain via Polkadot-JS is essential for full control over your digital assets.
Understanding USDT on Polkadot Asset Hub
Tether (USDT) has been officially deployed on both Polkadot Asset Hub and Kusama Asset Hub (formerly Statemine), enabling trustless and efficient transfers of this widely adopted stablecoin. The deployment was approved through democratic governance via Referendum 80 on Polkadot, ensuring community consensus and transparency.

A key innovation introduced with this rollout is that USDT is classified as a sufficient asset. This means recipients do not need to hold DOT (the native token) to receive USDT, eliminating a major friction point in cross-wallet transactions. However, there are still minimal balance requirements:
- Polkadot Asset Hub: Minimum USDT balance of 0.01 USDT
- Kusama Asset Hub: Minimum USDT balance of 0.0001 USDT
While transaction fees are still paid in the native relay chain token (DOT or KSM), the sender only needs enough DOT to cover gas—making it easier than ever to onboard new users.
Important Security Note: Verify the Correct Asset ID
One critical aspect often overlooked is asset authenticity. Anyone can create a token named "USDT" on Asset Hub with any symbol. To ensure you're interacting with the official Tether issuance, always verify the asset ID:
- ✅ Official USDT Asset ID:
1984(on both Polkadot and Kusama)
This unique identifier guarantees you’re sending and receiving legitimate USDT backed by Tether Limited. Always double-check this value before initiating any transfer.
⚠️ Tether has announced the discontinuation of USDT on Kusama. Users are strongly advised to redeem their USDT from Kusama Asset Hub (Statemine) by transferring to a supported exchange like Bitfinex before the official sunset date.
Step-by-Step Guide: Transferring USDT via Polkadot-JS UI
Although user-friendly wallets such as Talisman and Nova are recommended for everyday use, Polkadot-JS UI remains the go-to interface for developers and advanced users who require granular control over chain interactions.
Follow these steps to transfer USDT on Polkadot Asset Hub:
Step 1: Connect to the Correct Network
- Open Polkadot.js Apps
- In the top-left corner, click the network selector
- Choose “AssetHub” under the Polkadot section (not the Relay Chain)
This ensures you’re interacting with the correct parachain where USDT resides.
Step 2: Navigate to Assets Balances
- Go to Network > Assets > Balances
- Click on the "Balances" tab
- From the dropdown menu, select asset ID 1984 (official USDT)
Your current USDT balance will now be displayed.

Step 3: Initiate the Transfer
- Click the “Send” button next to your USDT balance
Enter the recipient's address carefully
- Ensure it supports Asset Hub deposits
- Addresses starting with
1are typically valid for Polkadot
- Input the amount of USDT to send
- Confirm the transaction fee will be deducted in DOT
Step 4: Sign and Submit
- Select your connected wallet (e.g., Polkadot.js Extension)
- Review all details
- Click Sign and Submit
Once confirmed, the transaction will be processed on-chain. The recipient will see the USDT appear in their Asset Hub account, not on the main Polkadot Relay Chain.
ℹ️ Note: Transferred assets remain within the Asset Hub environment. They won’t show up in wallets that only track native DOT balances unless those wallets explicitly support parachain assets.
Key Considerations When Using Polkadot-JS UI
While powerful, Polkadot-JS UI requires technical awareness. Here are some best practices:
- Always verify asset IDs before sending
- Keep a small amount of DOT for transaction fees
- Use trusted devices and avoid public networks
- Regularly back up your seed phrase offline
For non-technical users, consider switching to Treasury-funded wallets like Nova or Talisman, which offer intuitive interfaces and built-in asset verification.
Frequently Asked Questions (FAQ)
Q: Do I need DOT in my wallet to receive USDT?
A: No. Since USDT is a sufficient asset on Asset Hub, recipients don’t need any DOT to receive it—only a compatible wallet that supports parachain assets.
Q: What happens if I send USDT to a regular DOT address?
A: If the address belongs to a wallet that supports Asset Hub (like most modern Polkadot wallets), the transfer should succeed. However, sending to an incompatible or outdated wallet may result in lost funds. Always test with a small amount first.
Q: Why is the asset ID important?
A: Because anyone can mint a fake "USDT" token, checking asset ID 1984 ensures you're dealing with the real Tether-issued stablecoin.
Q: Can I transfer USDT between Polkadot and Kusama?
A: Not directly. These are separate chains. You would need to bridge assets using protocols like xTransfer or XCMP-compatible dApps.
Q: Are there withdrawal fees when moving USDT to an exchange?
A: Fees depend on the exchange and network congestion. Always check minimum withdrawal thresholds and gas costs before initiating large transfers.
Q: Is Polkadot-JS safe for beginners?
A: It’s designed for advanced users. Beginners should use more intuitive wallets funded by the Polkadot Treasury for better UX and safety features.
