Onii’Chain Is Using Chainlink VRF to Generate Provably Random NFTs
Following our launch, we are proud to announce that all Onii’Chain NFTs (Onii) are randomly generated using
Chainlink Verifiable Random Function (VRF).
Since an Onii NFT can wear extremely rare items — some with a 0.001% chance of dropping — we decided to integrate Chainlink VRF as a tamper-proof and auditable source of randomness in our NFT generation mechanism. The result is a high-integrity process for generating Onii NFTs based on true entropy.
Onii’Chain is a decentraliz
ed NFT platform on Ethereum, which means your avatar and its metadata is fully generated and stored on-chain with its own rarity system. Oniis can’t be stopped — once your Onii is generated, it will exist for eternity (or as long as Ethereum exists) and not “somewhere” on a centralized server.
In order to bring transparency and fairness to our NFT generation mechanism, we needed 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 derived from blockchain data like block hashes can be exploited by miners, while data derived from off-chain RNG solutions like traditional data providers are opaque and don’t provide users with definitive proof about the integrity of the process.
Now, Onii collectors can rest assured that their Oniis are generated with provably fair randomness based on cutting-edge academic research, time-tested oracle infrastructure, and the generation and on-chain verification of cryptographic proofs that prove the integrity of each random number supplied to smart contracts. To simplify the minting process from collectors, the Onii team is providing LINK tokens to the smart contract to call the VRF Coordinator.

“We’re excited to integrate Chainlink VRF into our NFT generation system because we believe in providing a fair, highly reliable, and fraud-proof gaming experience to our users” Onii’ Team.
Chainlink is the industry standard oracle network for powering hybrid smart contracts. Chainlink Decentralized Oracle Networks provide developers with the largest collection of high-quality data sources and secure off-chain computations to expand the capabilities of smart contracts on any blockchain. Managed by a global, decentralized community, Chainlink currently secures billions of dollars in value for smart contracts across decentralized finance (DeFi), insurance, gaming, and other major industries.
Chainlink is trusted by hundreds of organizations, from global enterprises to projects at the forefront of the blockchain economy, to deliver definitive truth via secure, reliable oracle networks. To learn more about Chainlink, visit
