LayerZero enables Cross-Chain Interoperability for Quantoz Stablecoins EURQ and USDQ

1 October 2025, UTRECHT, The Netherlands – Quantoz euro and dollar denominated stablecoins EURQ and USDQ are now integrated with LayerZero and Stargate. The first cross-chain connection is between Ethereum and Polygon, with further blockchain integrations to follow.  

By leveraging LayerZero’s messaging protocol and Stargate’s liquidity transport layer, EURQ and USDQ can now move seamlessly between supported blockchains. This interoperability significantly expands access for exchanges, liquidity providers, and application developers, while maintaining the strong regulatory oversight and safeguards that set Quantoz’ stablecoins apart. 

Arnoud Star Busmann, CEO of Quantoz Payments, commented: 

“Interoperability and cross-chain liquidity management are critical requirements for regulated stablecoins to achieve scale. Being available via LayerZero and Stargate, makes it easier for partners and exchanges to integrate EURQ and USDQ across multiple ecosystems, without compromising on the regulatory compliance, transparency, and security that institutions expect.” 

Ivar Wiersma, Business Development Lead EMEA at LayerZero, added: 

“We are pleased to welcome Quantoz’s MiCA-compliant stablecoins to the LayerZero and Stargate ecosystem. As demand grows for trusted, fiat-backed assets that can move freely across chains, this integration demonstrates how interoperability and regulation can go hand-in-hand.” 

As adoption of stablecoins accelerates globally, cross-chain capabilities will be key to ensuring seamless settlement, liquidity, and composability across DeFi, exchanges, and enterprise applications. EURQ and USDQ, fully backed and designed to be MiCA compliant, now combine regulatory trust with technical flexibility to serve these growing use cases.
