Onchain NAV for Fidelity’s Institutional Liquidity Fund
Chainlink, Fidelity International, and Sygnum partnered to bring Net Asset Value (NAV) data onchain to enable the tokenization of Fidelity International’s $6.9 billion Institutional Liquidity Fund on the zkSync public blockchain. With Chainlink, NAV data is accurately reported and synchronized onchain in an automated and secure manner, providing real-time transparency and built-in access to historical data for Sygnum, its clients, and broader market participants.
Crypto Finance brings Chainlink Proof of Reserve to ETPs
Crypto Finance, a leading provider of digital asset solutions for institutional clients and part of Deutsche Börse Group, has adopted the Chainlink data standard. Chainlink Proof of Reserve enables direct verification of assets custodied by Crypto Finance for nxtAssets’ physically backed Ethereum and Bitcoin Direct exchange-traded products (ETPs), with reserve data orchestrated by the Chainlink Runtime Environment (CRE) and published on Arbitrum.
MT103-initiated minting with custody verification
A depositor funds USD with a custodian, then the issuer submits a Swift-style MT103 to a CRE HTTP endpoint to trigger issuance, where a workflow performs a custody-powered mint check by calling Chainlink Proof of Reserve, and only mints onchain tokens if verified reserves are sufficient offchain.
Secure cross-chain transfers with Taurus-PROTECT
Chainlink CCIP extends the capabilities of Taurus-PROTECT by enabling secure, standardized cross-chain asset movement while preserving institutional custody controls. Assets such as USDC remain governed within Taurus-PROTECT’s custody and approval framework, while CCIP manages the cross-chain communication and transfer logic.
“Proof of Reserve marks a major step in institutionalizing trust and transparency for digital assets. With Chainlink’s technology, we can provide investors with verifiable information on reserves while maintaining the highest standards of security and operational integrity.”
“With the integration of proof of reserves and custom price feeds powered by the Chainlink Runtime Environment, investors can now independently verify not only price movements but also the authenticity and backing of the assets they hold. We are working to realize this potential together with an experience that extends from the moment of transaction to custody, in line with global standards and regulations in our country.”
“Stablecoins are driving innovation in financial markets, and issuers need a comprehensive solution—from reserves to issuance, distribution, custody, and compliance—that offers full visibility, including across multiple chains. By working with Chainlink, we are uniquely positioned to meet these critical market needs for large-scale stablecoin adoption.”
