Our initial integration involves the use of several different Chainlink Price Feeds, including BTC/USD, ETH/USD, and more. 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.

LendeXe Finance is a holistic liquidity ecosystem that starts with one of the most widely adopted products in Web3 — stablecoins. The LendeXe Finance ecosystem primarily revolves around two decentralized stablecoins, XSD and LXD, alongside a lending and borrowing protocol. XSD is secure because it is backed by USDT, USDC and BUSD and has mechanics that can absorb a crash of one of these stablecoins. The goal of all LendeXe products is to provide users with top-notch security while unlocking liquidity through three main levers:

  • Dynamic lending — lend a range of digital assets to access interest, or borrow up to a predefined threshold for various digital assets.
  • Ultimate Loan (UL) — Add in LEXE as collateral to garner XSD as debt.
  • Interest-Free Loan (IFL) — Add in BTC, ETH, or BNB as collateral to garner LXD as debt.

In order to help accurately calculate borrowing limits, liquidation thresholds, and other mission-critical functions needed within the LendeXe Finance ecosystem such as informing the XSD Stabilizer, 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.

“Without access to robust and reliable price data feeds, it’s impossible to build secure, feature-rich DeFi functionality. That’s why we chose to use Chainlink Price Feeds — the undisputed industry standard price oracle solution in DeFi.” LendeXe Finance team.

About LendeXe Finance

LendeXe is a Web3 ecosystem with several innovative DeFi applications. The past has shown that many Stablecoins are not really stable. This was mainly due to the fact that various Stablecoins were backed by volatile tokens. At the center of LendeXe’s vision is the XSD Stablecoin. XSD is a secure Stablecoin because it is backed by three of the other largest Stablecoins: USDT, USDC, BUSD. XSD also features built-in safety mechanics to help prevent issues if USDT, USDC, or BUSD, go offpeg. XSD’s Stabilizer will have at least 10 stablecoins in total by the end of 2023 Q4 in order to be able to scale to the maximum in favor of the XSD users.

That’s why LendeXe offers users several ways to mint XSD Stablecoins. In addition, XSD can be used as collateral for the LendeXe Decentralized Lending Protocol and also in the Ultimate Loan (a loan for 1.5x the value of your collateral), and the upcoming Interest Free loan (IFL).
