We are pleased to announce that we have integrated Chainlink Verifiable Random Function (VRF) into the Sphynx Network on Polygon to maximize the full potential of secure random number generation in the DeFi and GameFi space.

Chainlink VRF is supplying tamper-proof random numbers to the Sphynx Society platform to help power the creation of provably random NFTs with unique trait combinations. We will further use Chainlink VRF in gameplay for Sphynx Wars, a blockchain-based play-to-earn NFT game.

The integration of Chainlink VRF features two different phases, and Phase One is already complete.

Phase One: Sphynx Society NFT integration

Chainlink VRF provides a random number to the Sphynx Society smart contract paired with cryptographic evidence that the number was generated securely, enabling any party to audit the outcomes and ensure the randomness was tamper-proof.

Chainlink VRF works by combining block data that is still unknown when the request is made with the oracle node’s pre-committed private key to generate both a random number and a cryptographic proof. The Sphynx Society smart contract will only accept the random number input if it has a valid cryptographic proof, and the cryptographic proof can only be generated if the VRF process is tamper-proof. This helps provide users with automated and publicly verifiable proof directly on-chain that using Chainlink VRF for randomness is provably fair and cannot be tampered with or predicted by the oracle, outside entities, or the Sphynx Network team.

Phase Two: Game integration

Sphynx Wars will use Chainlink VRF to add a randomness factor to the outcome of PvP and PvE in-game interactions. Essentially, every time a player attacks another player, Sphynx Wars will use Chainlink VRF to generate random numbers determining how strong the attack was, how well the other player defended, how much loot the attacker can take away, and so on. Using Chainlink VRF will help demonstrate to our users that competitions are verifiably fair, which will help keep the game from becoming pay-to-win.

Chainlink Provides Security and Transparency

After evaluating several alternatives, we selected Chainlink VRF because it is based on rigorous academic research, it’s run by the same Chainlink node operators that already help secure tens of billions in on-chain value in DeFi, and it demonstrates the randomness of each operation is provably random through on-chain cryptographic proofs.

“We’re excited to see Sphynx Society and Sphynx Wars come to life using Chainlink — the blockchain industry’s most secure and time-tested infrastructure. Chainlink gives our users verifiable randomness in NFTs and soon in-game battle outcomes.”

— Madalin Muraretiu, CEO & founder of Sphynx Society


Chainlink is the industry standard for building, accessing, and selling oracle services needed to power hybrid smart contracts on any blockchain. Chainlink oracle networks provide smart contracts with a way to reliably connect to any external API and leverage secure off-chain computations for enabling feature-rich applications. Chainlink currently secures tens of billions of dollars across DeFi, insurance, gaming, and other major industries, and offers global enterprises and leading data providers a universal gateway to all blockchains.
