How XAUt0 Works
XAUt0 enables omnichain movement of Tether Gold, a digital token backed by physical gold held in Swiss vaults. Built on a lock-and-mint architecture and powered by the Omnichain Fungible Token (OFT) standard, XAUt0 ensures secure, efficient, and fully backed cross-chain transfers.
Locking Assets: XAUt is locked in a smart contract on Ethereum Mainnet
Minting on Destination Chains: An equivalent amount of XAUt0 is minted on the target chain, maintaining a strict 1:1 backing with the Ethereum-based collateral.
Cross-Chain Transfers: XAUt0 uses an omnichain messaging layer to enable fast, cost-effective transfers between chains—bypassing traditional bridges and fragmented liquidity pools.
Redemption: Users can burn XAUt0 to unlock and redeem the original XAUt on Ethereum, preserving full backing and auditability.
Role of the OFT Model
XAUt0 leverages the OFT standard developed by LayerZero, creating a unified and scalable cross-chain infrastructure:
Unified Liquidity Management: Liquidity is consolidated across all supported chains, reducing fragmentation and boosting capital efficiency.
High Security: Cross-chain actions are validated by decentralized oracles and relayers, ensuring robustness and minimizing risk.
Scalability: The OFT model allows effortless onboarding to new chains as adoption grows.
Efficiency: Without wrapped tokens or intermediary bridges, the system remains simple and operationally lean.
By combining the reliability of gold-backed assets with the flexibility of omnichain technology, XAUt0 redefines how gold can be accessed and transacted across blockchain ecosystems.
