MetaGunner Integrates Chainlink Price Feeds to Help Secure Its NFT Marketplace

We’re excited to announce that MetaGunner — a Shooter NFT Game — has integrated Chainlink Price Feeds on Binance Smart Chain mainnet. By integrating the industry-leading decentralized oracle network, MetaGunner has access to high-quality, tamper-proof price feeds needed to help secure price conversions on the MetaGunner NFT marketplace. This will provide our users with stronger assurances that NFT prices on the MetaGunner marketplace are supported by high-quality market data that is hyper-resistant to single points of failure.

Our initial integration uses the BNB/USD Chainlink Price Feed, with additional feeds to be added as the use cases require. 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.

MetaGunner is a Run-and-Gun game built on Binance Smart Chain, where you can immerse yourself in battles located in a barren wilderness inhabited by monsters. Developed with the play-to-earn model, MetaGunner allows users to own unique NFTs represented as soldiers or weapons and obtain values with those NFTs. NFTs in MetaGunner actually work in a relatively simple way — the assets used within MetaGunner are programmed as NFTs, which have value among players and collectors and can also be sold.

Gaming has traditionally been pay-to-win, where users buy items and upgrades that help them advance in the game, but with no real economic return in the real world. The Play-to-Earn model in MetaGunner can instead act as a source of income for players who can gain valuable rewards for their activities in a game.

In order to help secure our NFT Marketplace price conversions, 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.

“With Chainlink Price Feeds, MetaGunner’s NFT Marketplace now has the high-quality price reference data it needed to help ensure users can seamlessly and securely convert assets and purchase items,” stated Andy Ly, founder and CEO of MetaGunner. “Chainlink Price Feeds stand out from other oracle solutions as they offer unrivaled reliability and security guarantees.”
