Metapoly Integrates Chainlink Price Feeds To Help Secure NFT Borrowing and Lending Operations
We’re excited to announce that Metapoly — a metaverse bank that unlocks liquidity and utility for metaverse assets — has integrated Chainlink Price Feeds as a part of our beta version. By integrating the industry-leading decentralized oracle network, Metapoly has access to high-quality, tamper-proof price feeds needed to help get the floor price of NFT collections. This helps us determine the amount of USDC that users can borrow using their NFTs as collateral, and check if users’ borrowing positions fall under the pre-set liquidation threshold. This will help provide our users with stronger assurances that the protocol remains collateralized at all times.
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.
Metapoly provides a decentralized borrowing & lending service on Ethereum that enables metaverse landholders to open collateralized debt positions (CDPs) using their land NFTs as collateral. Users can deposit their NFTs as collateral to borrow other digital assets such as USDC (USDT, ETH, and other stablecoins to be integrated in the near future) — effectively enabling them to obtain leverage on their NFTs.
In order to help secure collateralization calculations on our NFT borrowing & lending platform, 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.
“It’s critical for lending and borrowing platforms to utilize high-quality market data. The integration of Chainlink Price Feeds enhances the security and reliability of the Metapoly platform by providing highly accurate and robust NFT market data directly on-chain.” — Cindy Jin, co-founder of Metapoly
