FTSE Russell Publishes Market Index Data on Blockchain Using Chainlink Oracles
FTSE Russell, the global index and data provider behind some of the world’s most influential financial benchmarks, has entered the blockchain era by publishing its market index data on-chain for the first time through Chainlink, the leading decentralized oracle network.
A Major Bridge Between TradFi and DeFi
Through Chainlink’s DataLink service, FTSE Russell’s equity, FX, and digital asset benchmarks will now be available across multiple blockchain networks. DataLink connects traditional financial data to over 2,000 decentralized applications (dApps) across more than 50 blockchains, marking a milestone in merging traditional finance (TradFi) with decentralized finance (DeFi) infrastructure.
According to Fiona Bassett, CEO of FTSE Russell, the integration will allow the company to “securely distribute underlying data” from its benchmarks and provide “trusted, high-quality data that powers traditional finance” to institutions and blockchain developers alike. With this move, FTSE Russell’s global indices will become continuously available on-chain, enabling developers to reference, verify, and integrate benchmark data securely across networks.
Turning Indices Into On-Chain Financial Primitives
Ram Kumar, a core contributor at OpenLedger, described the integration as a step that “turns traditional reference indices into programmable, verifiable financial primitives.” He added that it “bridges TradFi standards with DeFi infrastructure,” helping bring institutional legitimacy to on-chain finance.
How Blockchain Oracles Enable Trusted Data
Blockchain oracles like Chainlink act as data bridges between on-chain smart contracts and the external world. These networks collect, verify, and deliver data from trusted sources through multiple independent nodes, producing cryptographically signed, tamper-proof records. This ensures accuracy, transparency, and security without relying on a single intermediary.
By bringing FTSE Russell’s indices on-chain, institutions can now launch tokenized index products, structured notes, and real-time on-chain price feeds backed by an $18 trillion benchmark provider. Developers, meanwhile, gain access to high-integrity, verifiable data for building index-tracking vaults, options, and autonomous agents, enabling auditable risk management and next-generation financial products.
This partnership signals a new phase of convergence between the legacy financial system and decentralized networks, as trusted market data becomes natively programmable on-chain.
