Crypto Finance, part of Deutsche Börse Group, has gone live with Chainlink’s Proof of Reserve technology, enabling on-chain verification of assets backing digital Exchange Traded Products (ETPs) issued by nxtAssets.
The move marks a significant step in bringing greater transparency to the crypto investment space, allowing investors to independently verify the reserves behind physically backed Bitcoin and Ethereum ETPs.
Stijn Vander Straeten, CEO of Crypto Finance, said the rollout “marks a major step in institutionalising trust and transparency for digital assets,” adding: “With Chainlink’s technology, we can provide investors with verifiable information on reserves while maintaining the highest standards of security and operational integrity.”
The integration involves three key players: nxtAssets as issuer, Crypto Finance as regulated custodian, and Chainlink providing decentralised, tamper-resistant data. Reserve information is published on Arbitrum via Chainlink’s Runtime Environment and cryptographically verified without exposing sensitive wallet details.
Fernando Vazquez, president of banking and capital markets at Chainlink Labs, said: “Transparency in digital asset markets requires more than periodic reporting—it requires continuously verifiable data. This live application establishes a new benchmark for trust and accountability in the global ETP market.”
The proof of reserve mechanism complements traditional net asset value reporting and is expected to streamline compliance, bolster institutional confidence, and support regulatory alignment.
Dirk Hess, managing director at nxtAssets, said the initiative “sets nxtAssets apart from other ETP providers,” noting that it “enhances transparency for end investors and provides greater visibility to regulators, auditors, and the broader market.”
Crypto Finance secured its MiCAR licence in January 2025 and is a SIX-approved custodian for ETP issuers. The firm’s latest move with Chainlink and nxtAssets signals a growing push for real-time transparency in tokenised investment products.
