Chainlink's data infrastructure is now live on the Stellar network. The October 14, 2026 launch brings Chainlink's Data Feeds and Data Streams to Stellar, giving developers the market data needed to build lending markets, prediction markets, perpetual futures and other decentralized finance (DeFi) applications, and connecting the network's tokenized assets to a broader set of onchain financial use cases.

The Stellar Development Foundation (SDF) said in a blog post that the integration removes a critical barrier to launching DeFi applications: access to reliable market data. The foundation framed the launch as a step beyond issuing assets onchain, toward pricing, trading and borrowing against them.

Chainlink brings new DeFi capabilities to Stellar

Data Feeds and Data Streams give Stellar developers the market information needed to build secure lending markets, prediction markets, perpetual futures and other onchain financial applications. Both services are now available natively on the network.

Oracles carry offchain market data, such as asset prices, onto blockchains so smart contracts can act on it. Within that category, Data Feeds provide decentralized price data onchain, while Data Streams deliver low-latency market data for time-sensitive applications.

Applications across the ecosystem are adopting the infrastructure at launch for collateral processing, loan-to-value calculations, automated liquidations and stablecoin reference rates — functions that the oracle data directly into the operation of financial markets on Stellar. That pricing layer is what lets lending protocols value collateral accurately and execute liquidations when markets move, the mechanics behind the foundation's framing of data access as the barrier to DeFi on Stellar.

Johann Eid, Chief Business Officer at Chainlink Labs, described the integration as support for a wider range of financial products. "The Stellar network's adoption of Chainlink as its data infrastructure unlocks new generation of DeFi and tokenized asset applications across its ecosystem," he said.

Eid added that the services provide the reliable data developers need to build and scale lending markets, stablecoins and tokenized assets. The SDF blog post describes Chainlink's oracle infrastructure as the same infrastructure used to secure the vast majority of DeFi, with tens of trillions of dollars in onchain transaction value enabled.

Putting Stellar's real-world assets to work

Stellar already supports more than $4 billion in real-world assets. The integration supplies data infrastructure intended to help those assets function as tradable instruments and collateral. According to the blog post, stablecoins and tokenized equities are among the assets that gain additional utility through DeFi applications.

The distinction, as the foundation presents it, is between creating an onchain asset and making it usable in financial markets: these assets need pricing, trading and borrowing functions, alongside the ability to serve as collateral.

Raja Chakravorti, the foundation's Chief Business Officer, said institutional-scale onchain markets require dependable infrastructure for pricing, execution and movement. He described Chainlink's data and connectivity as a foundation for financial applications that put issued assets to work.

Stellar provides smart-contract functionality through a payments-optimized protocol. Its design aims to keep transaction fees low and allow transaction speeds to scale with increased adoption.

Scale commitment supports cost-efficient oracle access

The launch follows Stellar's decision to join the Chainlink Scale program with a substantial capital commitment. The commitment is intended to give developers cost-efficient access to enterprise-grade oracle infrastructure.

Leading applications are adopting Chainlink on the Stellar network to support lending and collateral operations at launch, including loan-to-value calculations, collateral processing, automated liquidations and reference rates for stablecoins.

With both services live natively on the network, the integration links Stellar's base of tokenized assets to the oracle infrastructure widely used across decentralized finance. Near term, the observable markers are which ecosystem applications ship lending and trading products on the new data layer and how the Scale program's cost support lands for developers building on Stellar.
