The integration of Tether (USDT) on the Polkadot 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 blockchain platforms. This guide walks you through the complete process of transferring USDT using the Polkadot-JS UI, while ensuring safety, accuracy, and compliance with best practices.
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, the latter being its canary network. These system parachains allow for the creation and management of fungible assets with minimal friction.

While USDT is fully operational on Polkadot, note that Tether has announced the discontinuation of USDT on Kusama. Users holding USDT on Kusama Asset Hub (formerly Statemine) are strongly advised to redeem their tokens by transferring them to a compatible exchange such as Bitfinex before the official sunset date. Always refer to Tether’s official announcement for deadlines and redemption procedures.
Key Features of USDT on Asset Hub
- Sufficient Asset Status: Enabled via Referendum 80 on Polkadot, this means recipients do not need to hold DOT to receive USDT.
- Existential Deposit Waived: Unlike standard accounts requiring a minimum DOT balance, USDT transfers bypass this requirement.
- Minimum Balance Requirement: Recipients must still maintain at least 0.01 USDT in their account on Polkadot Asset Hub (0.0001 USDT on Kusama).
- Transaction Fees Paid in Native Token: Even though USDT is sufficient, transaction fees are paid in DOT when using Polkadot-JS UI.
Verify the Official USDT Asset
Since any entity can mint assets on Asset Hub, it's crucial to confirm you're interacting with the legitimate USDT token. The official USDT asset ID is 1984 on both Polkadot and Kusama chains.
Always double-check:
- The asset symbol:
USDT - The asset name:
Tether USD - The decimal precision: 6
- The correct ID:
1984
This prevents accidental transfers to fake or spoofed tokens.
Step-by-Step Guide: Transferring USDT via Polkadot-JS UI
Polkadot-JS UI is a powerful interface designed for advanced users who prefer direct interaction with the blockchain. Follow these steps carefully to send USDT from your wallet.
Step 1: Connect to the Correct Network
- Open Polkadot.js Apps
- In the top-left corner, click the network selector.
- Choose “AssetHub (Polkadot)” from the dropdown menu.
Ensure you are not connected to the Relay Chain or any other parachain.
Step 2: Navigate to Assets > Balances
- From the sidebar, go to Network > Assets > Balances.
- Click on the “Balances” tab.
- From the asset dropdown, select “USDT (1984)”.
This displays your current USDT balance linked to your connected account.
Step 3: Initiate the Transfer
- Click the “Send” button next to your USDT balance.
- Enter the recipient’s SS58-encoded address (must be compatible with Polkadot or Asset Hub).
- Input the amount of USDT to transfer (minimum: 0.01 USDT).
📌 Note: The recipient does not need DOT in their account to receive USDT, but they must already have an active account or hold at least 0.01 USDT.
Step 4: Confirm and Submit
- Review all details: recipient address, amount, and asset type.
- Sign the transaction using your wallet (e.g., Polkadot.js Extension).
- Wait for confirmation on-chain.
Once confirmed, the funds will appear under the recipient’s Assets > Balances section—not on the Relay Chain.

Frequently Asked Questions (FAQ)
Can I send USDT without holding DOT?
Yes, but only if the recipient already has an account with at least 0.01 USDT. If not, they’ll need someone to cover the existential deposit—or send enough USDT to meet the minimum threshold.
Why do I need DOT to send USDT?
Even though USDT is a sufficient asset, transaction fees are paid in DOT, the native token of Polkadot Asset Hub. Your wallet must hold a small amount of DOT to cover gas costs.
Is USDT on Kusama being phased out?
Yes. Tether has announced plans to discontinue USDT support on Kusama Asset Hub. Users should transfer their holdings to a supported exchange like Bitfinex before the shutdown date.
How do I verify I’m using the real USDT?
Check that:
- The asset ID is 1984
- The symbol is USDT
- It’s issued by a trusted source (Tether Operations Limited)
You can verify metadata through on-chain explorers like Polkascan or Subscan.
Will my USDT appear on the Relay Chain?
No. Assets sent via Asset Hub remain within that specific parachain. Recipients must use Polkadot.js Apps > Network > Assets > Balances to view their USDT.
What happens if I send USDT to an invalid address?
Blockchain transactions are irreversible. Always verify addresses carefully before sending. If sent incorrectly, recovery depends solely on the recipient’s cooperation.
Best Practices for Secure Transfers
- Always confirm the asset ID (1984) before initiating a transfer.
- Use trusted wallets like Polkadot.js Extension or Talisman.
- Keep a small reserve of DOT for transaction fees.
- Test with a small amount first when sending to new addresses.
- Bookmark official resources and avoid phishing sites.
Final Thoughts
Transferring USDT on Polkadot Asset Hub via Polkadot-JS UI offers direct, trustless access to one of the world’s most widely used stablecoins within a secure multichain environment. As Polkadot continues to expand its DeFi capabilities, mastering tools like Polkadot-JS becomes increasingly valuable.
While user-friendly wallets funded by the Polkadot Treasury offer simpler alternatives for daily use, understanding low-level interfaces empowers users with greater autonomy and transparency.
