Chainlink Enables Tether Gold to Launch on World Chain

oXAUt, the open version of Tether’s gold-backed token XAUt, is now available on World Chain, enabled by Chainlink CCIP and Hyperlane. This move allows users to access tokenized gold across multiple blockchains, solving long-standing issues around liquidity fragmentation, interoperability, and DeFi integration.

Tether Gold (XAUt) represents tokenized physical gold, with each token backed by a specific gold bar stored in Swiss vaults. While XAUt was originally issued as an ERC-20 token on Ethereum, its use in other ecosystems faced technical hurdles due to isolated bridges and non-composable wrappers.

oXAUt solves these limitations by introducing a multichain-compatible version of XAUt that can move freely across different chains with zero slippage, consistent pricing, and seamless integration into DeFi apps.

What Is oXAUt?

oXAUt is a multichain-compatible version of Tether’s XAUt, developed by Chainlink and Hyperlane. It mirrors the design of OpenUSDT, the open and composable version of Tether’s stablecoin USDT, and is backed 1:1 by the same physical gold as XAUt.

Key characteristics of oXAUt:

• Backed 1:1 by gold stored in Tether's Swiss vaults
• Fractional and portable, enabling smaller units of gold to be used in DeFi
• Built on Chainlink CCIP and Hyperlane, enabling secure, cross-chain transactions
• Open architecture, allowing integration into DeFi protocols across supported chains

Why Is oXAUt Important?

Liquidity Fragmentation Solved

Traditionally, bridging assets like gold tokens between chains introduced fragmentation. Different wrappers and single-purpose bridges led to multiple disconnected versions of the same asset. That meant lower liquidity, price differences, and difficulty integrating into DeFi.

oXAUt solves this by offering:

• A single interoperable token across all supported chains
• Consistent pricing and liquidity
• Composable integration into DeFi dApps without needing special versions for each chain

This approach ensures that whether users are on World Chain, Ethereum, or any other Superchain network, they’re interacting with the same oXAUt token standard.

The Role of Chainlink CCIP and Hyperlane

Chainlink CCIP: Security for Large Transfers

Chainlink’s Cross-Chain Interoperability Protocol (CCIP) plays a crucial role in enabling secure token transfers across networks.

CCIP secures:

• Message delivery between chains
• Value transfer accuracy
• Resistance to exploits common in older bridges

Hyperlane: Permissionless Interoperability

Hyperlane allows oXAUt to expand across multiple Superchain networks using a permissionless deployment model. Developers can bring oXAUt to new chains without waiting for a centralized approval process.

Hyperlane brings:

• Modular security that can adapt to future interoperability standards
• Compatibility with ERC-7802, Ethereum’s cross-chain token standard
• Future-proofing for when Tether natively mints USDT or XAUt on more chains

World Chain Users Can Now Access Tokenized Gold

With this launch, millions of users on World Chain can now hold, trade, and interact with tokenized gold directly in their wallets. They can:

• Use oXAUt as collateral in lending platforms
• Swap oXAUt in DEXs
• Hedge crypto volatility with gold, without leaving the onchain ecosystem

For DeFi builders, the integration of oXAUt means gold-backed assets are now composable across protocols with no special wrappers or bridges required.

Related Developments Strengthen Chainlink’s Role

oXAUt’s release comes alongside other notable moves powered by Chainlink infrastructure:

• Misyon Bank (Türkiye) integrated Chainlink’s Proof of Reserve, Data Feeds, and CRE to tokenize traditional assets with transparency
• EDinheiro (Brazil) began using Chainlink in its social currency system for underbanked communities, bringing local aid onto secure blockchain rails

These developments show a consistent push toward secure, verifiable, and interoperable tokenized assets across the globe.

Frequently Asked Questions (FAQs)

1. What is oXAUt and how is it different from Tether’s XAUt?

   oXAUt is an open, multichain version of Tether’s XAUt gold token. Unlike XAUt, which was limited to Ethereum, oXAUt can move freely across multiple blockchains using Chainlink CCIP and Hyperlane.

2. Is oXAUt backed by real gold?

   Yes, oXAUt is backed 1:1 by physical gold bars stored in Tether’s Swiss vaults, just like XAUt. The difference is that oXAUt uses a composable, multichain architecture.

3. Which chains support oXAUt?

   oXAUt is currently live on World Chain, with plans to expand to more Superchain networks over time. Any chain compatible with Chainlink CCIP or Hyperlane can support oXAUt.

Conclusion: What oXAUt Brings to the Crypto Ecosystem

oXAUt makes it possible to interact with gold across chains starting with Worldchain without fragmentation or wrappers. By building on Chainlink CCIP and Hyperlane, it supports seamless composability, secure bridging, and integration into DeFi applications—regardless of chain.

It brings:

• Stable store of value onchain
• Composable liquidity across chains
• Secure, interoperable architecture
• Tools for both individual and institutional users to access tokenized gold
