Tether-linked USDT0 and XAUT0 launch on Solana via LayerZero tech

USDT0 and XAUT0 — cross-chain bridged versions of Tether's USDT stablecoin and Tether Gold (XAUT) managed and operated by Everdawn Labs — have launched on Solana via LayerZero's interoperability technology.

While Tether's USDT has been available on Solana for years, USDT0 aims to expand its liquidity reach.

"Existing USDT on Solana can only circulate within the Solana ecosystem," Lorenzo R., co-founder of USDT0, told The Block. "With USDT0, Solana is directly linked to more than $175 billion in native USDT liquidity across Ethereum, Tron, TON, and other major chains — with no wrapped assets, no external bridges, faster settlement, and lower fees."

Meanwhile, Tether Gold is expanding to Solana for the first time through XAUT0.

"The combination of omnichain dollars and gold-backed value gives developers and institutions a foundation to build the next generation of applications, ranging from global remittances and corporate treasuries to programmable lending and asset-backed innovation," Lorenzo said.

Everdawn Labs brings Tether’s USDT and XAUT tokens to more blockchains via its "Legacy Mesh" platform — a cross-chain liquidity infrastructure powered by LayerZero’s interoperability protocol. Legacy Mesh is a stablecoin-specific interoperability layer, not a general multi-asset bridge, Lorenzo noted. Every transaction on Legacy Mesh is "fully backed by real assets," with auditable liquidity pools and no wrapped or synthetic tokens, he added, noting that transfers carry a 0.03% fee paid in USDT.

The current circulating supply of USDT0 is about 7.5 billion tokens and XAUT0 is about 7,355 tokens, according to CoinGecko. For comparison, USDT’s circulating supply exceeds 180 billion and XAUT’s totals 375,572.

USDT0 and XAUT0’s Solana expansion adds to their growing network footprint. USDT0 is live on Plasma, Polygon, Arbitrum, Berachain, Ethereum, Ink, Flare, Optimism , Hyperliquid’s HyperEVM, SEI, and Rootstock , while XAUT0 is currently available on TON, HyperEVM, Arbitrum, Ink, CELO, Avalanche, and Polygon.

Lorenzo said additional network launches are planned.

"Although we can't say which ones exactly, USDT0 evaluates new chain deployments through three core pillars including: user engagement and ecosystem demand, chains that offer something distinct and unique to the ecosystem, and the potential for growth and long-term value for the Tether ecosystem," he said.
