The digital asset sector is advancing its cross-chain capabilities as Tether strategically deployed omnichain versions of its stablecoin, USDT, and Tether Gold, XAUT, onto the Solana blockchain. This integration utilizes the LayerZero-powered Legacy Mesh network, a framework designed to enable seamless cross-chain liquidity without requiring users to rely on wrapped assets or complex third-party bridging solutions.
This architectural decision introduces USDT0 and XAUT0 tokens to the Solana ledger, aiming to solidify Solana’s role as a primary settlement layer for on-chain finance and tokenized real-world assets. By leveraging Legacy Mesh, Tether addresses the persistent industry challenge of liquidity fragmentation, facilitating native asset interaction across chains. The objective is to streamline operations for institutional adoption in areas such as global remittances, treasury management, and advanced collateralized lending protocols.
The deployment follows previous successful rollouts of USDT0 across major ecosystems, including Ethereum, Polygon, TON, OP Superchain, and Arbitrum. Since its inception across these chains, the USDT0 product has processed over $25 billion in bridge volume and executed more than 32,000 transfers. This development serves as a significant validation of Solana’s infrastructure for hosting high-value, institutional-grade financial activity.
Tamar Menteshashvili, the Head of Stablecoins at the Solana Foundation, stated that this partnership is set to catalyze accelerated growth for decentralized finance applications and payment rails built on the Solana network. The adoption of LayerZero technology within Legacy Mesh underscores a commitment to secure, standardized communication layers between blockchains, a crucial factor for attracting conservative institutional capital by minimizing counterparty risk inherent in traditional bridging models.
Market data from October 17, 2025, frames this integration within a dynamic environment. Solana (SOL) traded at approximately $195.92 with a market capitalization near $110.2 billion, while Tether Gold (XAUT) held a market cap around $888.13 million, trading near $4,213.11. This strategic move aligns the stability of USDT and the tangible value of XAUT with Solana’s high-throughput capabilities, creating a more unified and efficient plane for digital value transfer.
