Axie Infinity Integrates Chainlink Oracles!

Axie Infinity
4 min readNov 16, 2020

This is an announcement we’ve been looking forward to for many months now.

Today, we’re proud to share that we’ve completed integration of Chainlink decentralized price feeds! In addition, we’ll be using Chainlink Verifiable Randomness Function (VRF) to introduce provably fair random elements into the Axie universe, starting first with Axie Origin Coins (AOC).

What is Chainlink?

Chainlink is the market-leading decentralized oracle network providing real-world data to smart contracts on any blockchain. It allows dApps like Axie Infinity to consume data from outside the Blockchain, such as data from web APIs, premium data providers, IoT networks, enterprise backends, and more.

What is Axie Infinity?

Axies are fierce creatures that love to battle, build, and hunt for treasure!

‌Players can build up a collection of Axies and use them across an ever expanding universe of games!

Axie Infinity is currently the #1 game on Ethereum, with over 14,000 monthly on-chain users, and over 11,000 daily off-chain users.

We recently launched our native token, AXS, which uses governance and fee sharing to align incentives between all members of the Axie ecosystem.

Integration details

As the first step in our collaboration, Axie has integrated the Chainlink ETH/USD Price Reference Data feed into our marketplace. This price feed serves as a very important exchange rate to ensure that marketplace users have accurate prices when making a purchasing and listing decision. In addition, mainstream users find USD price feeds more familiar so its important for adoption that we get this right.

Currently, we’re getting our price feeds from centralized servers which can go down and be disrupted. With Chainlink price feeds, we can ensure 100% uptime for our marketplace’s all-important ETH/USD price feed. We feel confident integrating this key exchange rate via Chainlink because it’s secured by a decentralized network of high-quality oracle nodes that provide accurate price data sourced from a variety of excellent off-chain data aggregators.

In addition, we’ll be using Chainlink VRF for the generation of Origin Axies from Axie Origin Coins (AOC)! The number of Origin Axies in the game is capped at 4088. Each time 5 AOC are burned, an Origin Axie is born with a chance of possessing Mystic parts. The chance of an Axie possessing Mystic parts when they’re born from AOC will soon rely on the VRF!

This is an incredibly important task considering the scarcity of Mystic Axies is central to their value. In fact, a Mystic Axie just sold for 300 ETH and the event was covered by CoinTelegraph! Talk about famous digital pets.

We selected Chainlink VRF because it provides a highly secure source of randomness that is permissionless and auditable on-chain by all users. This provides users with cryptographic proof that all random elements are provably fair, and cannot be manipulated by our team or any external entities.

The Future of Axie Infinity and Chainlink

Once Ronin, our Ethereum sidechain, is live, we’ll explore integrating Chainlink VRF functionality into more Axie-related smart contracts.

Chainlink also makes a host of fun features possible because it provides access to any off-chain API. We believe we have only scratched the surface in how external data can be incorporated in Axie to enhance gameplay and the user experience.

Finally, we’d like to formally invite the Chainlink Marines to start playing Axie! Special thanks to @ChainlinkGod for his work educating us on the benefits of integrating Chainlink feeds into our ecosystem!
