EMDX Integrates Chainlink Price Feeds for Secure Crypto Perpetual Swaps

We’re excited to announce that EMDX — the novel DeFi DEX — has integrated Chainlink Price Feeds on Avalanche mainnet. By integrating the industry-leading decentralized oracle network, EMDX has access to high-quality, tamper-proof price feeds needed to help ensure crypto perpetual swaps are using institutional-grade market data to determine contract outcomes.

Our initial integration involves the use of the following Chainlink Price Feeds: BTC/USDC, AVAX/USDC, and ETH/USDC. We chose Chainlink as our go-to oracle solution because its infrastructure is seamless to integrate and time-tested in production. Chainlink already helps secure leading DeFi protocols responsible for tens of 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.

EMDX’s goals consist of bringing synthetic crypto assets to the Web3 ecosystem and building the next generation of innovative DeFi products, while maintaining the core benefits that DEXs offer, including self-custody of funds, ready-to-use services, and near-instantaneous asset flows.

In order to help secure our perpetual swaps, we needed 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. Thus, we needed to make use of an oracle network to fetch aggregated price data off-chain and deliver it on-chain to be consumed by our application.

After reviewing various oracle solutions, we integrated 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, leading to 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 more precise 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.

“We’re excited to integrate the industry-leading Chainlink Price Feeds on EMDX, helping secure our perpetual swaps with high-quality, reliable, and decentralized market data.” — Bernardo Corti, founder of EMDX.
