USDT0 and XAUT0 — cross-chain versions of Tether’s stablecoin (USDT) and Tether Gold token (XAUT) — have been launched on the Solana blockchain. Both assets are managed by Everdawn Labs and operate based on LayerZero technology, enabling interoperability between networks without the use of wrappers or third-party bridges.
New architecture for Tether liquidity
While the classic USDT has long circulated within the Solana ecosystem, the USDT0 version solves the key problem of liquidity isolation. Now, Solana is directly connected to over $175 billion in USDT liquidity placed across Ethereum, Tron, TON, and other blockchains.
“Previously, USDT on the Solana network was limited to internal circulation. With the launch of USDT0, Solana becomes part of a unified Tether liquidity ecosystem with fast settlements and minimal fees,” project co-founder Lorenzo R. explained in a comment to The Block.”
At the same time, Tether Gold is making its debut on Solana in the XAUT0 format. According to the developers, the combination of the “omnichain dollar” and a gold-backed token will create a foundation for new solutions in cross-border settlements, corporate treasuries, lending, and tokenized assets.
Everdawn Labs and the Legacy Mesh platform
Both tokens are integrated through the Legacy Mesh infrastructure, developed by Everdawn Labs and built on the LayerZero protocol. This system differs from classic bridges: it is focused exclusively on stable assets and operates without wrappers or synthetic tokens.
“Every transaction in Legacy Mesh is fully backed by real assets and has verifiable liquidity pools,” Lorenzo noted. “The transfer fee is only 0.03%, and it is paid in USDT.”
The platform allows institutional investors and developers to move liquidity between blockchains without losing speed or security, making it a potentially significant element in the Tether ecosystem.
Large-scale presence and expansion plans
According to CoinGecko, there are already 7.5 billion USDT0 and about 7,355 XAUT0 in circulation. For comparison, the total supply of the base USDT exceeds 180 billion tokens, and Tether Gold — 375,572 XAUT.
Solana is just one direction of expansion. USDT0 is already available on Plasma, Polygon, Arbitrum, Berachain, Ethereum, Ink, Flare, Optimism, SEI, Rootstock, and Hyperliquid’s HyperEVM. XAUT0 is present in the TON, CELO, Avalanche, Polygon, Arbitrum, Ink, and HyperEVM networks.
Everdawn Labs plans further integrations. Lorenzo noted that the choice of new networks will depend on three factors:
- user activity and ecosystem demand
- unique features of a particular network
- potential for long-term growth for the entire Tether infrastructure
Significance for Solana and the Tether ecosystem
The launch of USDT0 and XAUT0 on Solana strengthens the network’s position as a platform for high-speed settlements and institutional solutions. This event also highlights Tether’s strategy to expand its presence in the multichain space without relying on third-party bridges.
According to analysts, this model of interaction could become the standard for the future of DeFi — where liquidity and assets move freely between networks without loss of transparency and trust.
