Chainlink Proof of Reserve provides real-time updates for reserves backing digital assets with superior transparency and reliability compared to annual statutory audits, interim audits, and monthly proof of reserves, establishing a new standard of transparency for the digital asset industry.
This week, Virtune, a leading Swedish-regulated digital asset manager and crypto exchange-traded products (ETP) issuer, integrated Proof of Reserve to enhance the institutional transparency of assets underlying its ETPs.
With over $450 million in assets under management across 19 ETPs and more than 150,000 investors, Virtune’s products are listed on major European exchanges such as Nasdaq Stockholm, Nasdaq Helsinki, Deutsche Börse Xetra, Euronext Amsterdam, and Euronext Paris.
The initial integration will bring real-time onchain reserve transparency to Virtune Bitcoin ETP, Virtune Bitcoin Prime ETP, Virtune Chainlink ETP, Virtune Arbitrum ETP, Virtune Polygon ETP, and Virtune Staked Solana ETP, with plans to implement Proof of Reserve across Virtune’s entire ETP suite.
Powered by Chainlink’s SmartData framework, Proof of Reserve leverages Chainlink’s highly resilient oracle infrastructure, which has enabled over $26 trillion in transaction value, to verify that digital assets and financial products are fully collateralized. This real-time onchain verification provides institutional-grade assurance that complements traditional custodial oversight and auditing practices.
In an official announcement, Christopher Kock, CEO, co-founder, and board member at Virtune, called the integration a “significant step” in setting a higher standard for trust and accountability in the crypto ETP industry.
“Providing transparency into the assets backing our crypto ETPs is core to our mission at Virtune. Chainlink Proof of Reserve is the industry benchmark for onchain reserve verifications, and integrating it enables us to deliver real-time, tamper-proof insights into our reserves.”
“Virtune’s integration of Chainlink Proof of Reserve across their full suite of crypto ETPs marks a major leap forward in transparency and trust for digital asset markets,” added Colin Cunningham, Global Head of Tokenization and Alliances at Chainlink Labs.
“As institutional-grade products become more deeply integrated with blockchain infrastructure, real-time, verifiable data becomes essential. We’re proud to support Virtune in setting a new standard for onchain financial transparency and helping accelerate the evolution of capital markets.”
