Omnichain versions of the Tether stablecoins USDt (USDT) and Tether Gold (XAUT) are now available on Solana via Legacy Mesh, an interoperability network built on LayerZero that connects the native liquidity of stablecoins across multiple blockchains; this could position Solana as a competitive settlement layer for onchain finance and real-world assets (RWA).
The implementation of USDT0 and XAUT0 effectively brings Tether’s digital dollar and tokenized Tether gold to Solana, potentially connecting stablecoin liquidity with real-world asset apply cases.
Unlike Tether’s USDT stablecoin, USDT0 is not issued by Tether. Instead, it is part of an external omnichain liquidity network designed to unify existing native USDT liquidity across multiple blockchains. As such, the integration with Solana potentially strengthens Tether’s reach on omnichain, following previous USDT0 implementations on Ethereum, OP Superchain, Polygon, TON, and Arbitrum.
Legacy Mesh enables interoperability by connecting native USDT liquidity pools, allowing stablecoins to move between networks without relying on wrapped tokens or third-party bridges. However, risk mitigation and liquidity fragmentation remain ongoing challenges in multi-chain systems, making it hard to forecast how much USDT liquidity will actually migrate to Solana.
The expansion increases access to USDt Tether, the largest stablecoin by market capitalization, with a total circulating supply of about $180 billion, according to the companies.
Since launch, USDT0 products have processed more than $25 billion in bridging volume across more than 32,000 transfers, the companies said.
Tamar Menteshashvili, director of stablecoins at the Solana Foundation, said the integration will support the development of institutional-grade decentralized finance, payments and financial products on the Solana platform. In practice, this may include financial management, remittances and secured loans.
Although less well-known, XAUT0 represents the omnichain version of Tether Gold, which has gained attention amid the year-long rally in gold prices. XAUT introduces the yellow metal to the blockchain, giving it programmable functions similar to digital assets such as Bitcoin (BTC).

Stablecoins and RWA are gaining popularity on Solana
Solana, long known in cryptocurrency circles as one of the fastest-growing blockchain networks, is increasingly attracting the attention of time-honored finance. With a market capitalization of approximately $112.6 billion, Solana is the second largest sharp contract platform after Ethereum.
According to Matt Hougan, chief investment officer at Bitwise Asset Management, Solana is poised to win over Wall Street, potentially becoming banks’ preferred stablecoin transaction network.
At the same time, RWA tokenization on Solana is accelerating. Protocols such as Splyce and Chintai have recently introduced products that allow retail investors to access tokenized securities directly on the network.
Despite this energetic, Solana still represents only a diminutive portion of the overall RWA market, with approximately $694 million in tokenized assets currently on-chain, according to industry data. Ethereum remains the largest network for RWA, supporting nearly $12 billion in value.
This gap highlights competition among blockchains seeking to attract institutional financing and real-world asset flows, especially amid pro-industry regulatory change in the United States.
