Omnichain versions of the stablecoin USDT and tokenized gold XAUT from Tether are now available on the Solana network. The integration is implemented through the Legacy Mesh protocol based on LayerZero.
The Legacy Mesh and XAUt0 are live on @solana.

Developers believe this will strengthen Solana’s position as a settlement layer for on-chain finance and RWA.
The USDT0 and XAUT0 assets are not issued directly by Tether. They are part of a third-party omnichain network that unites native USDT liquidity across different blockchains. Previously, USDT0 was deployed on the Ethereum, OP Superchain, Polygon, TON, and Arbitrum networks.
Legacy Mesh ensures interoperability by uniting native USDT liquidity pools. This allows stablecoins to move between networks directly, without using wrapped tokens or third-party bridges. This approach addresses asset fragmentation and eliminates risks that remain relevant for multichain systems when using third-party solutions.
According to the companies, since its launch, more than $25 billion has passed through USDT0 via 32,000 transactions. The total capitalization of the USDT stablecoin is approximately $181 billion.
Head of Stablecoins at the Solana Foundation, Tamar Menteshashvili, stated that the integration will support the growth of DeFi, payments, and institutional-level financial products on Solana. This particularly pertains to treasury management, remittances, and collateralized lending.
XAUT0 is the omnichain version of Tether Gold. The product brings physical gold onto the blockchain, endowing it with programmable features similar to digital assets like Bitcoin.
As reported by Bloomberg, Tether and the Bitmain-affiliated financial firm Antalpha plan to raise $200 million for a structure that will form a treasury in XAUT.
