Legacy Mesh
The Legacy Mesh is USDT0's cross-chain liquidity infrastructure that connects legacy USDT deployments with the USDT0 omnichain network through a shared, non-custodial hub. USDT0's docs list Ethereum, Tron, TON, Solana and Celo for native USDT, with Arbitrum as the canonical USDT0 hub, and say these chains keep their existing USDT implementations. It is designed to link them without replacing contracts, migrating users or relying on wrapped assets.
