Arbitrum will provide infrastructure to connect USDT0 to Ethereum, Tron and Ton

The Arbitrum One blockchain will provide the core infrastructure for USDT0, the new, interoperable Tether stablecoin. The blockchain will host the Legacy Mesh solution to connect USDT deployments on Arbitrum, Ethereum, Tron and Ton to a unified USDT0 network.  

Thanks to Legacy Mesh, users will be able to move USDT between chains for lower costs and with greater access to liquidity pools. USDT0 is intended to free up siloed liquidity by eliminating the burdensome process of bridging. USDT0 is backed 1:1 with USDT.

Legacy Mesh will leverage LayerZero’s interoperability protocol.

USDT0 will increase access to liquidity pools

Steven Goldfeder, co-founder and CEO of Arbitrum developer Offchain Labs, said, “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.”

Users will be able to interact with USDT- and USDT0-supported chains. Many emerging blockchain ecosystems, such as Ink, Berachain and MegaETH, support USDT0, according to an Arbitrum press release.

The new solution will also permit frictionless transfers of USDT to Telegram wallets, Tether CEO Paolo Ardoino said on X. By linking the four major blockchains, the introduction of USDT0 connects $138 billion of Tether into a single system. According to the USDT0 blog on Mirror, that represents 98% of all Tether.

Tether is thriving despite MiCA

Tether began its transition from bridged USDT to USDT0 in January with an automatic swap on the Arbitrum chain, which is a layer-2 Ethereum scaling solution that uses optimistic rollups for consensus. 

Tether recorded a profit of $13 billion in 2024, despite the boost its competitors received when USDT was excluded from the European Union in July by Markets in Crypto-Assets regulations. It remains by far the largest stablecoin by market cap.

Tether’s fortunes look bright in the United States, where newly reelected President Donald Trump is seen as a supporter of dollar-pegged stablecoin in general and Howard Lutnick, CEO of investment firm Cantor Fitzgerald has been nominated to be the next secretary of commerce. Cantor Fitzgerald is the portfolio manager of Tether’s U.S. Treasury securities.
