The cryptocurrency ecosystem continues to evolve, and with it, the demand for seamless cross-chain asset transfers has never been greater. At the heart of this transformation is USDT0, a groundbreaking development in the world of stablecoins. Launched by Tether on January 16, 2025, USDT0 introduces a new paradigm for cross-chain liquidity by leveraging LayerZero’s Omnichain Fungible Token (OFT) standard on Kraken’s Ethereum Layer 2 network, Ink.
Designed to unify fragmented USDT liquidity across blockchains, USDT0 eliminates the inefficiencies, high costs, and security risks associated with traditional cross-chain bridges. This article explores the technology behind USDT0, its benefits for developers and users, and how it’s poised to redefine stablecoin interoperability in the DeFi and Web3 landscape.
The Problem with Traditional USDT
Despite being the world’s largest stablecoin—with a market cap exceeding $143.57 billion as of February 11, 2025—USDT has long struggled with liquidity fragmentation. Each blockchain hosts its own version of USDT (e.g., ERC-20 on Ethereum, TRC-20 on Tron), requiring users to rely on third-party bridges for cross-chain movement.
These bridges come with significant drawbacks:
- High transaction fees
- Security vulnerabilities
- Liquidity pool dependency
- Price slippage
- Complex user experience
As a result, transferring USDT between chains is often slow, expensive, and risky—hindering capital efficiency and user adoption across decentralized applications.

Introducing USDT0: A Unified Stablecoin Experience
USDT0 addresses these challenges head-on by creating a single, omnichain version of USDT that moves natively across supported blockchains without wrappers or intermediate liquidity pools.
Built using LayerZero’s OFT standard, USDT0 operates through a mint-and-burn mechanism:
- Lock: USDT is locked in a smart contract on Ethereum.
- Mint: An equivalent amount of USDT0 is issued on the target chain (e.g., Ink, Arbitrum).
- Transfer: Users move USDT0 across chains seamlessly.
- Redeem: USDT0 can be burned and redeemed 1:1 for USDT on Ethereum at any time.
This process ensures full backing, eliminates double-spending risks, and maintains price parity across all chains.

How USDT0 Works: The Technology Behind the Innovation
The OFT Standard and LayerZero Integration
USDT0 uses the Omnichain Fungible Token (OFT) standard developed by LayerZero, enabling secure and efficient token transfer across multiple blockchains. Unlike traditional bridging models, OFT does not require liquidity pools or wrapped tokens.
Key advantages include:
- Unified liquidity: Shared across all chains, reducing fragmentation.
- Enhanced security: Utilizes decentralized oracles and relayers to verify cross-chain messages.
- Scalability: Enables rapid deployment on new blockchains.
- Cost efficiency: Eliminates intermediary fees and reduces gas costs through lightweight messaging.
By integrating LayerZero’s ultra-light client architecture, USDT0 minimizes on-chain computation, streamlining cross-chain communication and lowering operational overhead.
Legacy Mesh: Connecting Major USDT Ecosystems
Launched on February 12, 2025, the Legacy Mesh connects key USDT ecosystems—Tron, TON, Ethereum, Arbitrum, Ink, and Berachain—enabling smooth transfers between them.
With support for both single-hop (e.g., Tron → TON) and multi-hop (e.g., Tron → Arbitrum → Ink) transfers via usdt0.to/transfer, Legacy Mesh covers nearly 98% of global USDT supply, ensuring broad interoperability from day one.
Why Was Ink Chosen for Initial Deployment?
USDT0 debuted on Kraken’s Layer 2 network, Ink, for several strategic reasons:
1. Exchange Backing and Liquidity Access
Kraken is one of the world’s leading crypto exchanges. Its integration allows users to deposit and withdraw USDT0 directly through their Kraken accounts, providing instant access to deep liquidity pools.
2. Low-Cost Layer 2 Architecture
Ink uses rollup technology to drastically reduce gas fees compared to Ethereum L1. This makes USDT0 ideal for high-frequency trading, micropayments, and DeFi applications requiring cost-effective transactions.
3. Security and Regulatory Compliance
Backed by Kraken’s compliance infrastructure, Ink offers a secure environment for issuing and managing USDT0. As the first L2 to support USDT0, it serves as a pilot network to test scalability and security under real-world conditions.
4. Advanced Interoperability
Ink is designed for seamless L2-to-L2 communication. Once USDT0 is live on Ink, it can easily expand to other Layer 2 networks, paving the way for broader omnichain adoption.
Andrew Koller, founder of Ink, described the launch as setting a “new standard for stablecoin liquidity.”

How USDT0 Reduces Cross-Chain Transfer Costs
Traditional cross-chain bridges incur multiple cost layers:
- Bridge fees
- Liquidity provider fees
- High gas costs from multi-step processes
- Slippage due to shallow pools
- Arbitrage-driven price discrepancies
USDT0 eliminates these inefficiencies through:
✅ Direct Mint-and-Burn Mechanism
No need for liquidity pools—tokens are minted directly on the destination chain after being burned on the source.
✅ Lower Gas Fees
LayerZero’s lightweight client reduces on-chain verification complexity, cutting gas consumption significantly.
✅ Elimination of Slippage
With unified liquidity sharing across chains, asset conversion remains stable at 1:1 without depth-related slippage.
✅ Price Stability Across Chains
Consistent issuance mechanics prevent price divergence, reducing arbitrage opportunities and hidden costs.
This results in faster, cheaper, and more predictable cross-chain transfers—critical for institutional traders and DeFi protocols alike.
