- Tether has partnered with Arbitrum to launch Legacy Mesh, a cross-chain initiative that enables seamless USDT transfers across multiple blockchains without token wrapping.
- This move enhances interoperability, strengthens Tether’s financial dominance, and comes amid growing regulatory scrutiny of stablecoin reserves.
Tether, the company behind the world’s largest stablecoin USDT, has chosen Ethereum Layer 2 protocol Arbitrum as the backbone of its new cross-chain initiative, Legacy Mesh. This move aims to enhance interoperability across multiple blockchain networks while eliminating the need for token wrapping or third-party bridges.
A Unified Network for USDT Transfers
The Legacy Mesh initiative introduces a new token, USDT0, which is pegged one-to-one with USDT. With a market cap of $141 billion, Tether continues to push for innovations that simplify stablecoin transfers. USDT0 operates on LayerZero’s Omnichain Fungible Token (OFT) standard, a system previously adopted by PayPal’s PYUSD stablecoin.
By utilizing Arbitrum as the “hub chain,” USDT0 will seamlessly link USDT deployments across several blockchain ecosystems, including Ethereum, Tron, Ton, Ink, and Berachain. This approach ensures that liquidity remains deep and accessible, regardless of the blockchain users operate on.
Steven Goldfeder, CEO of Offchain Labs, the team behind Arbitrum, highlighted the significance of this collaboration, stating, “The Legacy Mesh is an important milestone for Arbitrum, ensuring that users and developers have access to deep, liquid markets regardless of the blockchain they are on.”
Tether’s Expanding Interoperability and Financial Strength
Tether has been aggressively expanding its interoperability capabilities throughout 2025. In January, it announced support for Bitcoin via the Lightning Network, demonstrating its commitment to making USDT widely accessible across different blockchain environments.
Financially, Tether continues to report impressive growth, with Q4 profits exceeding $13 billion. The company has also increased its exposure to U.S. Treasuries, solidifying its position as a dominant player in the stablecoin sector.
Regulatory Scrutiny and Future Outlook
Despite its financial success, Tether remains under the watchful eye of regulators. Howard Lutnick, President Donald Trump’s pick for commerce secretary, recently voiced support for implementing government audits on stablecoin reserves. This initiative aims to ensure stablecoins like USDT maintain their dollar peg and remain a trusted asset in the crypto space.
Meanwhile, Arbitrum continues to prove itself as a powerful infrastructure provider. Beyond supporting Tether’s Legacy Mesh, the blockchain recently facilitated the launch of BitcoinOS, a rollup layer designed to connect Bitcoin users with Ethereum-based DeFi applications.
As Tether strengthens its multi-chain presence, its partnership with Arbitrum marks a pivotal step toward a more interconnected and efficient stablecoin ecosystem. With seamless USDT transfers now possible across major blockchain networks, users can expect faster and more secure transactions without the complications of wrapped assets.
