Tether has officially launched its omnichain tokens USDT0 and XAUT0 on Solana, connecting the blockchain to over $175 billion in cross-chain liquidity.
Quick Summary – TLDR:
- Tether’s USDT0 and XAUT0 tokens are now live on Solana through LayerZero’s interoperability tech.
- These tokens connect Solana to native liquidity on Ethereum, Tron, TON, and more.
- USDT0 already processed over $25 billion in volume across nine networks.
- XAUT0 marks the debut of Tether Gold on Solana, enabling programmable gold-backed assets.
What Happened?
Tether has expanded its digital asset ecosystem by launching USDT0, a bridged version of its USDT stablecoin, and XAUT0, the omnichain edition of its gold-backed token, XAUT, on Solana. This move is powered by LayerZero, a cross-chain communication protocol, and managed by Everdawn Labs.

Tether Expands Cross-Chain Liquidity to Solana
With the new launch, Solana users now gain access to Tether’s massive cross-chain liquidity without relying on wrapped assets or third-party bridges. This expansion allows direct transfers between Solana and major chains like Ethereum, Tron, TON, and others.
USDT0 and XAUT0 are not replacements for their native counterparts. Instead, they are designed to extend the reach of USDT and XAUT to blockchains where Tether is not natively available. According to Lorenzo R., co-founder of USDT0, this integration allows Solana to tap into a liquidity pool exceeding $175 billion across multiple networks, offering lower fees, faster settlements, and reduced risk by avoiding synthetic or wrapped tokens.
Powered by Legacy Mesh and LayerZero
At the core of this rollout is Legacy Mesh, a stablecoin-native liquidity infrastructure built by Everdawn Labs using LayerZero. Unlike generic asset bridges, Legacy Mesh focuses exclusively on stablecoins and tokenized assets like gold, ensuring every transaction is fully backed by real assets.
- Transaction fee: 0.03 percent, paid in USDT
- No wrapped or synthetic tokens
- Auditable liquidity pools
This approach boosts security and transparency, both critical factors for institutional finance and DeFi users.
Tether Gold Debuts on Solana
The launch of XAUT0 brings Tether Gold to Solana for the first time, introducing a gold-backed asset into the chain’s DeFi ecosystem. This opens up new use cases such as:
- Programmable lending tools
- Collateralized debt positions
- Gold-based hedging strategies
With gold prices approaching record highs, XAUT0 adds real-world asset stability to Solana’s fast and low-cost network.
Adoption Metrics and Network Reach
According to public data:
- USDT0 circulating supply: Approximately 7.5 billion tokens.
- XAUT0 circulating supply: Around 7,355 tokens.
- USDT total supply: Over 180 billion tokens.
- XAUT total supply: Approximately 375,572 tokens.
Since its inception, USDT0 has processed over 320,000 transactions and $25 billion in bridge volume across nine networks. The Solana integration marks yet another milestone in expanding omnichain functionality.
Industry Support and Future Expansion
Tamar Menteshashvili, Head of Stablecoins at the Solana Foundation, said the integration strengthens both ecosystems by giving users access to the fastest and most cost-efficient stablecoin experience in DeFi, institutional finance, and payments.
Everdawn Labs plans to continue expanding USDT0 and XAUT0 to additional blockchains. According to Lorenzo, new chain deployments are assessed based on:
- User engagement and demand
- Unique technical features
- Long-term growth potential
SQ Magazine’s Takeaway
This move by Tether is huge. I love how it strips away the old hassles of wrapped assets and slow bridges. With LayerZero and Legacy Mesh, Tether is making stablecoins and gold-backed tokens easier to use across blockchains, and Solana just got a major upgrade. USDT0 and XAUT0 are setting the tone for what cross-chain assets should look like: fast, backed by real value, and cheap to use. It is a strong sign that DeFi is growing up and getting serious about interoperability.
