CosmicSwap Launches The Random Drawing System With Chainlink VRF on Binance Smart Chain

Our previous announcement stated our intent to integrate Chainlink Verifiable Random Function (VRF) as part of our CosmicSwap random drawing system. We’re excited to announce that the integration is now live on Binance Smart Chain (BSC) mainnet, enabling us to use the random function, by generating four random numbers for the drawing. These four random numbers then decide the winners of the giveaway. The drawing tickets include four random numbers. If all four random numbers on the ticket match the four winning random numbers, the user has won the highest price pot in the random drawing. If only two or three numbers match, the user will win smaller pots in the drawing. Ultimately this creates a more exciting, transparent, and fraud-proof user experience, as users can rely on a fair and random drawing system on the CosmicSwap platform.

The random drawing system is now live on our BSC app and can be found here.

After reviewing various solutions, we selected Chainlink VRF because it’s based on cutting-edge academic research, supported by Chainlink’s time-tested oracle infrastructure, and secured through the generation and on-chain verification of cryptographic proofs that guarantee the integrity of each random number supplied to smart contracts.

“The CosmicSwap team has been working hard on the final steps of integration with Chainlink’s VRF technology, and we’re super excited to release it to our community.” –Azure, Project Lead
