Today, we are excited to introduce the Legacy Mesh, the solution for connecting USDT0 and USDT deployments across all chains: from Tron, Ton, and Ethereum, to Arbitrum, Ink and Berachain.

While USDT0 solves USDT’s expansion to new chains, the Legacy Mesh brings interoperability to ecosystems where a USDT deployment is already present. With Arbitrum acting as a hub chain between USDT and USDT0 chains, USDT holders are just a single hop away from Ink, Berachain, and MegaETH, along with other upcoming USDT0 chains.

This brings us one step closer to our goal: accelerating USDT liquidity across chains.

The Legacy Mesh is designed to connect USDT between four of the largest USDT blockchains:

• Ethereum

• Ton

• Arbitrum

• Tron

For chains like Ethereum, Tron, and TON , the mesh uses liquidity pools to facilitate transfers. Powered by LayerZero messaging, the Legacy Mesh lets users move assets between these massive chains cheaply and securely.

The Legacy Mesh connects USDT deployments—Ton, Tron, and Ethereum —to the largest USDT0 deployment on Arbitrum, creating a unified network.

With these four chains now linked, 98% of all USDT exists within a single seamless system, with USDT0 serving as the cornerstone for expanding this mesh to even more networks.

Paolo Ardoino, CEO of Tether, said: “The Legacy Mesh is bringing 138B USDT together, making it a crucial advancement toward a unified onchain dollar system. It simplifies the movement of liquidity from already established chains like Tron and Ethereum into new and exciting ecosystems like TON and the USDT0 networks in a fully permissionless and self-sufficient way.”

The Legacy Mesh makes native USDT composable across the chains that have historically been the home to the majority of stablecoin usage: Tron, TON, and Ethereum. It also connects these chains to the rest of crypto through USDT0, thanks to the Arbitrum USDT0 integration.

Until now, most cross-chain solutions for USDT were based on third-party, unofficial bridges. This led to liquidity fragmentation and more complex token management across blockchains. Now, Arbitrum powers seamless interoperability for USDT0, ensuring users can easily access liquidity from both. This not only improves efficiency, but the depth of DeFi protocols on the network. Arbitrum’s efficient and cost-effective cross-chain transfers solidify its status as a premier liquidity hub for financial interconnectivity.

Steven Goldfeder, Co-Founder and CEO of Offchain Labs, commented, “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. We’re thrilled that Arbitrum has been chosen as the hub for this innovation, serving as the foundation for broader USDT adoption while delivering unmatched liquidity and scalability across blockchain networks.”

USDT transfers are simple and seamless, requiring only interaction with the Legacy Mesh through https://usdt0.to/transfer. Users can initiate a transfer on Tron and receive it directly in their TON wallet in a single transaction. While multihop transfers are more complex, they still maintain the intuitive user experience characteristic of USDT0 products. Here is an example:

Tron USDT holders can now send their assets to Ink in just two simple steps:

1. Utilize the native mesh to move USDT from Tron to Arbitrum

2. Easily enter the USDT0 network on Arbitrum and transfer funds to Ink—enjoying the capital efficiency, zero fees, and lightning-fast transactions that define USDT0.

For users interacting with non-EVM blockchains (such as Tron or Ton), it’s essential to:

• Connect the correct recipient address for the destination chain

• Use a compatible wallet that supports the selected blockchain

• Double-check network selection before confirming a transfer

By following these simple steps, USDT holders can confidently move their assets across Legacy Mesh supported chains, minimizing friction while maximizing interoperability. The Legacy Mesh makes cross-chain USDT transfers more accessible, efficient, and user-friendly than ever before.

Transfer your USDT anywhere, from a single place: https://usdt0.to/transfer

Legacy Mesh transfers are live, along with transfers to Arbitrum. Multihop transfers from Legacy Mesh chains to USDT0 chains outside of Arbitrum, like Ink and Berachain, are coming soon.

In terms of stablecoin usage, the Legacy Mesh brings the dream of “borderless programmable dollars” to life by making USDT available anywhere, in a single experience powered by Arbitrum.

The linking of the Legacy Mesh and USDT0 powered by Arbitrum cements the future of USDT expansion, bringing together USDT chains and USDT0 to provide a single system for dollars to be used onchain – on any chains.
