Celsius Secures Backend Pricing of Crypto Using The Chainlink, A Major Leap in CeFi Decentralization

5 min readAug 5, 2021


In one of the most ambitious moves towards decentralization, Celsius is now leveraging the industry-leading Chainlink Price Feeds to increase reliability of price feed for our backend systems. The deeper integration with Chainlink involves the use and sponsorship of over 90 decentralized price feeds, making it one of the first times a CeFi platform is issuing loans to users based on a fully decentralized and transparent pricing mechanism.

We selected Chainlink to help facilitate our move towards decentralization because its Price Feeds are thoroughly time-tested in production, successfully securing tens of billions of dollars in value through even the most extreme market volatility. Chainlink Price Feeds supply high-quality data on all platform assets and are backed by robust infrastructure that has proven to be highly resilient during unexpected events, such as top cryptocurrency exchanges experiencing downtime, flash crashes, and data manipulation attacks. This is one of the many steps Celsius plans to take towards decentralization.

The result of the integration is a seamless union between CeFi and DeFi — Celsius continues to provide users with an impeccable customer experience for accessing low-cost loans and earning high yield, while Chainlink decentralizes a core part of the Celsius backend system to bring unprecedented guarantees around fair and transparent pricing of crypto assets.

Celsius is a crypto lending platform accessible via a mobile app that lets users earn weekly rewards on their crypto. Our aim is to bring unparalleled access to fair, rewarding financial services to a global audience and provide the best opportunity for our users to earn consistent rewards or receive dollars without having to cash out their cryptocurrency holdings.

Crypto holders can transfer their coins to their Celsius account and start earning rewards or borrow USD or stablecoins against it with low rates. Celsius supports today’s top cryptocurrencies, as well as a wide assortment of stablecoins. As of writing, Celsius has over $15.6 billion in community asset holdings and has paid out yield of over $340 million to users in the past 12 months.

As our platform scales alongside the flourishing new crypto economy, we must ensure that the underlying infrastructure powering our app scales in its security to meet the demands of our growing user base. We at Celsius are very mindful of the critical importance of having accurate, up-to-date, and manipulation-resistant price data when performing various borrowing and lending operations.

The upgrade to Chainlink Price Feeds will not only further decentralize our platform, but it will make our price data more robust during market volatility or centralized infrastructure failures. Celsius will reference Chainlink Price Feeds every time a user supplies collateral to obtain a loan, effectively determining their borrowing rate. We are also actively exploring the use of Chainlink Price Feeds within our liquidation mechanism.

Some of the most notable features of Chainlink Price Feeds that make them reliable enough to be used within a high-value CeFi platform like Celsius include:

  • Market Coverage — Chainlink Price Feeds source data from numerous premium data aggregators, leading to price data that’s aggregated from hundreds of exchanges, weighted by volume, and cleaned from outliers and wash trading. Chainlink’s data aggregation model mitigates situations where a single or small set of exchanges report inaccurate prices or experience manipulation.
  • Low Deviation Updates — By using the Chainlink Price Feeds running on Polygon, we have access to low deviation price updates at minimal costs, meaning the price data is precise, consistently up to date, and reflective of current market conditions.
  • Robust Infrastructure — Chainlink Price Feeds utilize decentralized networks of professional node operators run by leading blockchain DevOps teams and traditional enterprises with a strong track record of uptime during market volatility.
  • Transparent Monitoring — Chainlink provides a robust reputation framework and set of on-chain monitoring tools that allow users to independently verify the historical and real-time performance of price feeds.

“We’re excited to deepen our integration with Chainlink, bringing newfound decentralization and transparency to the CeFi space. Users will now rely directly on Chainlink Price Feeds to determine the size of collateral they provide when borrowing through Celsius, the first step in a deeper backend integration of Chainlink and Celsius,” stated Alex Mashinsky, CEO of Celsius. “Chainlink Price Feeds have demonstrated industry-leading data quality and infrastructure, helping Celsius evolve to meet the growing global demand for crypto loans.“
