Moon Robots Integrates Chainlink Price Feeds to Help Secure In-game Minting

We’re excited to announce that Moon Robots — an NFT Strategy and RPG play-to-earn game — has integrated Chainlink Price Feeds on Harmony mainnet. By integrating the industry-leading decentralized oracle network, Moon Robots can leverage high-quality, tamper-proof price feeds to provide users with easily understandable prices for in-game minting.

Our initial integration involves the use of the following Chainlink Price Feeds: ONE/USD and ONE/ETH. 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.

Key components of the Moon Robots game are Robot Hero NFTs, Moon Land NFTs, Item NFTs, and the OIL token. The game aims to be fully on-chain, with no server or client used to process or store player data. As a web-based game, it’s tailored for both a smooth desktop and mobile user experience.

In order to help secure our in-game minting mechanics, 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.

Beyond the Chainlink Price Feeds integration, we plan to leverage Chainlink Keepers and Chainlink Verifiable Random Function (VRF) as the game continues to develop and Moon Robots expands across multiple chains.

“As the most widely used decentralized oracle network, Chainlink was the best solution for sourcing price data feeds that made the minting process for Moon Robot NFTs more user-friendly.” — Froggie, CEO of Moon Robots.
