We’re excited to announce that MultiPad will be integrating Chainlink Verifiable Random Function (VRF) on the Binance Smart Chain, Polygon and Avalanche mainnets.

By integrating Chainlink’s industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable source of randomness needed to select lottery winners for our partner IDOs.

Ultimately this creates a more exciting, transparent, and fraud-proof user experience, as users can be confident in the fair process that Chainlink propagates, allowing random selection of participants for our IDOs..

Simply put, MultiPad is ‘Committed to Community’ by creating a fair launchpad that allows holders of its native token to enter lotteries to win guaranteed allocations in partner IDOs. Hold more tokens to have a bigger chance of winning as investors get one lottery ticket for every 10,000 tokens staked. It’s as simple as that.

In order to ensure that there is absolute fairness in the draw and giving each lottery ticket equal weighting, we need access to a secure random number generator (RNG) that any user could independently audit. However, RNG solutions for smart contracts require several security considerations to prevent manipulation and ensure system integrity. For instance, RNG solutions using on-chain data like block hashes can be exploited by blockchain miners, while off-chain RNG solutions like traditional data providers are opaque and don’t provide users with definitive proof about the integrity of the process.

After reviewing various solutions, we selected Chainlink VRF because it is 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.

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 MultiPad 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 provides our users with automated and verifiable assurances directly on-chain that the launchpad lottery is provably fair and cannot be tampered with by the oracle, outside entities, or the MultiPad team.

As we are dedicated to the promises we have made to our community, MultiPad will continue to develop and that includes leveraging as much of Chainlink’s technology as possible, to further develop more innovative and immutable ways to maintain fairness and value on our platform.

“MultiPad is all about being fair to the community and Chainlink’s VRF gives absolute transparency to the community regarding the whitelist selections,” says Mr Green, co-founder at MultiPad.
