Why Chainlink for DeFi?

Most decentralized and secure

Chainlink oracle networks are secured by node operators running security-audited software that has been rigorously validated to operate at scale without downtime or corruption.

Highest quality data, resistant to manipulation

Data is sourced from multiple premium, authenticated APIs that are aggregated into a final validated answer, removing any single point of failure.

Most widely adopted oracle network in DeFi

The Chainlink Network helps secure tens of billions of dollars within the DeFi ecosystem by connecting hybrid smart contracts with high-quality data and offchain computation. 

Rapid integration and deployment

Developers can rapidly build, test, and deploy advanced DeFi applications that leverage multiple external resources using pre-built and reliable decentralized services.

A diverse range of decentralized services

Chainlink powers numerous decentralized services, including Data Feeds, Proof of Reserve, Automation, Verifiable Randomness Function, and Cross-Chain Interoperability.

Blockchain-agnostic oracle networks

Developers building DeFi applications have access to external data and computation across all leading smart contract-enabled blockchain networks to support multi-chain development.

Build DeFi applications across a multitude of use cases

Use Price Data Feeds to concentrate liquidity to the market price and help solve the issue of capital efficiency, Automation to execute limit orders and create a more powerful trading experience, and CCIP to move tokens across chains in a frictionless and secure manner.
Use Price Data Feeds to help secure the minting of decentralized and algorithmic stablecoins by liquidating positions, adjusting bonding curves, and recalibrating incentive mechanisms to help ensure peg stability, increasing confidence in the usability of stablecoins in the process.
Represent real-world assets as on-chain tokens using Price Data Feeds to help secure the minting and redemption processes, enabling redemptions to occur as expected. Fetch data from any API to mirror exposure to any arbitrary data value and significantly increase the class of assets tokenized on-chain. 
Grant users rewards for participating in a DeFi application’s ecosystem using Price Data Feeds to tie reward amounts to the value of deposits, creating predictability for users. Use Verifiable Randomness Function to introduce additional gamification, keeping users engaged in using the protocol. 
Generate on-chain insurance agreements that help users such as farmers to hedge against adverse conditions using Weather Data Feeds, or leverage real-world datasets fetched from any API to unlock the ability for anyone in the world to acquire insurance and hedge risk around any event. 

Leading projects across DeFi choose Chainlink

Synthetic Assets

"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."

Money Markets

“The security provided by the Chainlink Network's oracle infrastructure has served the Aave protocol well, and now users of the Aave protocol can leverage Chainlink's offchain service to participate in the Aave ecosystem as liquidators to secure the Aave protocol and its liquidity pools."

Decentralized Exchange

“Many people overlook the importance of oracles in their smart contract application. The reality that we see time and time again is that a smart contract application’s security is only as strong as its oracle. That’s why it was so important for our team to find an oracle that matched Trader Joe’s strong commitment to security.”

Staking

“Chainlink effectively serves as a great enabler for DeFi protocols looking to quickly and securely add support for a wide range of assets, removing manual processes and mitigating security risks around using unproven oracle solutions.”

Decentralized Exchange

“At DODO, we believe in leveraging industry expertise and forging strong, meaningful relationships. Chainlink is the undisputed leader in the oracle space — it has a proven track record of solving the oracle problem and providing high-quality data to live DeFi applications.”

stablecoins

“Using Chainlink oracles to secure collateral, redemptions, and liquidations was a clear step in further securing the Liquity protocol and improving its capital efficiency. This allows us to focus on building production systems at a much faster pace.”
