Build DeFi products across a multitude of use cases


Blockchain-based derivatives platforms require the price of real-world assets in order to provide reliable on-chain valuations. Use Chainlink reference contracts to mint synthetic assets, settle futures contracts, or price options.

"Given our reliance on regular price feeds for our derivatives trading mechanism, finding a robust decentralized oracle solution has always been at the top of our priority list. Chainlink delivers the solution, deployed by an excellent team and supported by an invaluable community."

Lending and borrowing

Lending and borrowing platforms require a price feed to ensure the total value of the collateral. Use Chainlink to issue and settle loans, liquidate collateral, and calculate interest payments.

"Chainlink helped us reduce our time to market, while at the same time providing the highest guarantee of data integrity, decentralization, and security."

Stablecoins require a price feed to assert the value of the underlying collateral backing the asset. Use Chainlink to create stablecoins pegged to fiat currency, currency baskets, or commodities.

"The oracle system is core to the Ampleforth protocol. Integrating and working with a trusted partner like Chainlink to ensure reliable data feeds decentralizes the oracle system is key to Ampleforth’s future."

Asset management

Asset management platforms require a reliable price feed for critical rebalancing of asset ratios. Use Chainlink to enhance a DEX, adjust capital pools, or facilitate multiple forms of payment.

“Integrating Chainlink’s Price Reference Contracts as the basis for rebalancing our capital pool brings tremendous security to our members, who know that our most important assets are deeply insulated against any known or unexpected attack vectors.”

Data providers

Data aggregators are professional service providers with a history of accurately curating key data points from various exchanges and providing the most reliable prices to the ecosystem. These resilient service providers support the Chainlink Network and are leveraged by node operators to provide accurate price feeds to the ecosystem.

Node operators

Node operators are the bridge between an on-chain price feed and an API. They run secure blockchain infrastructure that allows them to plug into virtually any type of API endpoint. Node operators on the Chainlink Network are fully transparent and identifiable, with strong existing reputations in the blockchain space, verifiable by DeFi developers.
