How to Mint USDT0

USDT0 is Tether’s omnichain, canonical version of USDT, designed to unify stablecoin liquidity across chains using LayerZero’s OFT protocol1 2 3 4+2.

Standard USDT Minting (Background)

To mint standard USDT, individuals or corporations must:

Register and verify an account with Tether (either as an Individual or Corporate). This involves comprehensive know-your-customer (KYC), anti-money laundering (AML), and counter-terrorism financing (CTF) compliance with a $150 fee8 9 10.
After verification, the user can deposit fiat (minimum deposit: $100,000) via wire transfer to Tether. Fiat deposits are charged a 0.10% fee.
Upon successful deposit, equivalent USDT tokens are issued to the user’s address on any natively supported blockchain11.

USDT0 Minting and Migration: What’s Different?

Automatic Upgrade: If you already hold USDT on Arbitrum, it was automatically upgraded to USDT0 during the migration process starting January 28, 2025. No user action was required for this transition1 3.
Interoperability: USDT0 is backed 1:1 by USDT on Ethereum and moves across chains by burning on one chain and minting on another, allowing for fast omnichain transfers without using bridges or wrappers2 3 4 5+1.
For New Mints on Chains with USDT0: After the migration, any new USDT minted into the Arbitrum network (as well as other future supported networks like Ink, Berachain, MegaETH) will utilize the USDT0 infrastructure, routing deposits through this new system1 2 3 5. The contract address remains unchanged and 1:1 collateralization is maintained2 13.

Instructions for Minting USDT0

Institutional Pathway: If you are an institution or corporation, you must first complete KYC/AML verification with Tether, paying the required fees8 9. Tether Registration
Fiat Deposit: After account approval, deposit fiat currency (minimum $100,000) via wire transfer to Tether’s account, specifying the desired network (e.g., Arbitrum, Ink, etc.)11.
Token Issuance: After receiving your deposit and selecting the destination network, Tether mints the equivalent amount of USDT0 to your submitted wallet address on the chosen blockchain.
Cross-chain Movement: To move USDT0 between supported networks—such as between Arbitrum, Ethereum, and Ink—you simply initiate a cross-chain transfer using the enabled omnichain protocol (LayerZero’s OFT), which burns the token on one network and mints it on another4 5.

Key Points and Reminders

No User Action Needed for Holders: The USDT0 transition for existing USDT holders on Arbitrum was seamless and required no user intervention1 3.
USDT0 Is Fully Backed: USDT0 is 1:1 collateralized by USDT on Ethereum. It is not a wrapped or synthetic asset, but uses omnichain infrastructure for native composability4 5 13.
Regulatory and Risk Audited: The upgrade was audited by multiple security providers and reviewed by independent risk auditors for solvency, liquidity, and compliance controls13.

For standard USDT mints or other networks, the process still involves Tether account verification, fiat wire deposits, and minting by Tether. For USDT0, any USDT minted into the canonical Arbitrum contract or migrated chains will now be issued as USDT0 and backed as described above.
