We’re excited to announce that Equalizer, the first dedicated flash loans marketplace in the decentralized finance market, will integrate Chainlink Price Feeds on Ethereum and Binance Smart Chains protocols. By integrating Chainlink’s industry-leading decentralized oracle network, Equalizer will have access to high-quality, tamper-proof price feeds needed to display accurate data on the platform’s UI and to properly calculate the rewards from the yield farming program This will provide our users with strong assurances that all the values of the listed assets are consistent and accurate.

We chose Chainlink as our go-to oracle solution because its infrastructure is seamless to integrate and time-tested in production. Chainlink already secures leading DeFi protocols responsible for billions of dollars in smart contract value, maintaining robust security and high availability even amidst unexpected events, such as exchange downtime, flash crashes, and data manipulation attacks via flash loans.

We are building the Equalizer platform with the mission to prove that flash loans are not a trick, but a very useful tool in an open decentralized finance market. Having an exponential increase in volume, flash loans have become the must-have instrument for borrowers that engage in profitable transactions, like arbitrage, liquidations, collateral swapping, and portfolio rebalancing. At Equalizer we make flash loans easy to use, accessible and secure. We enable liquidity providers and borrowers to meet on the same decentralized marketplace and to benefit from the top advantages of the platform: the lowest fees in the market, a wide range of token selection, minimum available liquidity for all assets, easy to integrate with, and multi-chain compatibility.

In order to secure our price feed source, we need access to fresh asset prices that are supplied directly on-chain in a highly reliable manner. Fair market asset prices should reflect a volume-weighted average from all trading environments, so we need to make use of an oracle to fetch aggregated price data off-chain and deliver it on-chain to be consumed by our application.

After reviewing various oracle solutions, we selected Chainlink Price Feeds because they provide a multitude of critical features such as:

  • High-Quality Data — Chainlink Price Feeds source data from numerous premium data aggregators, ensuring broad market coverage through price data that’s aggregated from hundreds of exchanges, weighted by volume, and cleaned of outliers and wash trading. Chainlink’s data aggregation model generates accurate global market prices that are inherently resistant to inaccuracies or manipulation of any single or small set of exchanges.
  • Secure Node Operators — Chainlink Price Feeds are secured by independent, security-reviewed, and Sybil-resistant oracle nodes run by leading blockchain DevOps teams, data providers, and traditional enterprises. Chainlink nodes have a strong track record of reliability, even during high gas prices and infrastructure outages.
  • Decentralized Network — Chainlink Price Feeds are decentralized at the data source, oracle node, and oracle network levels, generating strong protections against downtime and tampering by either the data provider or oracle network.
  • Reputation System — 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 node operators and oracle networks.

“Flash Lending is already an important component of the decentralized finance market that is expanding on multiple chains. We are very excited to start our collaboration with Chainlink as we share the same vision of building scalable and multi-chain solutions for a reliable DeFi market with the highest level of security” — Iulian Nita, Equalizer’s Project Lead
