PolkaFantasy Integrates Chainlink VRF for Better Transparency

4 min readSep 13, 2021

We are delighted to announce the integration with Chainlink VRF (Verifiable Randomness Function) into our platform to ensure that the outcomes that are based on randomness are tamper-proof and unbiased. The integration of Chainlink VRF ensures that actions that include randomness will execute fairly, securely, without any manipulation from any stakeholder or user. The integration of this function on the gaming portion of the platform will also help introduce fair distribution as well as random traits to make the overall experience more exciting.

Why Chainlink VRF?

PolkaFantasy is a platform that engages creators, gamers, investors, and general anime lovers to their platform through their engaging gamified NFT experience. To make the project more community-centered, we periodically offers giveaways and airdrops to our members. Apart from this, users are challenged through missions that result in rewards. All these distributions require fairness and true randomness which is promised by the Chainlink VRF. With a team of academics and developers, Chainlink was able to develop a function that generates randomness that is verifiable on-chain. This enables a myriad of use cases to be implemented through smart contracts on any platform. We leverage this in multiple areas of our platform. Not only does this make the platform more exciting to use, but the transparently generated randomness highly increases the credibility of our products, including our blockchain game.

Use Cases

The integration with Chainlink VRF provides PolkaFantasy users with:

  • The assurance that actions on our platform that require randomness are executed without any bias or tamper from miners, developers, oracle operators, or any other users.
  • The VRF will be used as a part of PolkaFantasy’s NFT marketplace to facilitate transparent and randomized NFT distribution models as well as generate unpredictable experiences and traits.

PolkaFantasy has always believed in making integration that would benefit the platform in the long term by opening new avenues of potential uses to be explored. PolkaFantasy is set to launch our own game in 2022 in which the VRF can be integrated to bring exciting and unpredictable abilities to characters/heroes as well as bringing random rewards for completing milestones and challenges within the game.

Our CEO, Alex Hui, was very excited regarding the integration :

‘We are very excited to integrate Chainlink VRF (Verifiable Random Function) in PolkaFantasy. Chainlink technology brings our game to the next level, and offers our ecosystem a secure way to access randomness via smart contracts. We can’t wait to bring more amazement with this feature in the near future.’

About the VRF Integration

Chainlink has made it easier for developers to integrate their VRF into any project based on blockchain gaming, security, layer 2 protocols, and various other use cases with their comprehensive documentation. This can be further explored by visiting Chainlink or PolkaFantasy’s platform where the VRF has been integrated. Chainlink’s history of trust and security has been the prime reason for the integration as developers can provide proof to security-sensitive users through on-chain verification.


All in all, PolkaFantasy has always aimed to build communities through trust and transparency and we have made ChainLink integration to achieve these objectives along the way. Our team believes that Chainlink VRF will push this effort further ahead and will help the project every step of the way in achieving the objectives in its roadmap.
