Distribute rare non-fungible tokens (NFTs) and assign randomized attributes to NFTs, providing players access to auditable evidence that their NFT assets are created and awarded using tamper-proof randomness.
Build better games by leveraging random outcomes in your blockchain gaming application. Map generation, critical hits (battling games), matchmaking (multiplayer games), card draw order, and random encounters/events are now possible with VRF.
Distribute highly-coveted items like tickets events, select participants in a popular public sale, and choose presale winners for luxury items like rare shoes.
Generate rich experiences with challenging and unpredictable scenarios and environments, and find the perfect mix between strategy and fun by using randomness to determine outcomes in PvP battles and other scenarios.
Industry leaders use Chainlink VRF for its unmatched low-cost, reliability, and ease-of-use across blockchains. Integrate Chainlink VRF today to provide trustworthiness for your users.
“Verifiable randomness solutions like Chainlink VRF v2 are essential for developers introducing entropy into on-chain gaming and NFT experiences, empowering them to create fair and fraud-proof play-to-earn games.”
“Chainlink VRF’s tamper-proof and verifiable random number generator gives us a transparent source of on-chain entropy to demonstrably show that our team cannot influence the distribution of NFTs, giving each user a fair chance to mint the most collectible monsters.”
“Since launching PancakeSwap Lottery V2 with Chainlink VRF, each of our drawings has been publicly auditable, creating unprecedented fairness and transparency that’s likely to become an industry standard in blockchain gaming.”
“Chainlink VRF v2 provides us with full autonomy for setting our own block confirmation times, resulting in more flexibility when developing chance-based games and features for the growing Aavegotchi NFT metaverse.”
Produce fair and unbiasable randomness for your blockchain-based application’s outcome
All random number results are verifiable before becoming available to consuming smart contracts
Oracles are unable to manipulate the generated result, the only thing they can do is not respond
Build better experiences by leveraging random outcomes in your blockchain-based application
Provide users with cryptographic proof of your application’s integrity to facilitate a high level of trust
Broaden your user base by leveraging fair and unbiasable randomness for your application’s outcomes
On-chain block data is used as inputs to the RNG, which is combined with the oracle’s private key to generate a random value and proof
Each random result is verified on-chain with cryptographic proofs
Malicious users, node operators, and smart contract admins cannot tamper with the resulting randomness
Lower gas fees with Subscription Management App while delegating access to the Subscription’s balance to multiple consumer addresses
Take advantage of the most configurable VRF experience by setting custom callback gas limits, block confirmation time
Get even more randomness per request in an intuitive way
Traditional RNG solutions have no guarantee of tamper resistance and require complete trust in how randomness is generated.
Without on-chain cryptographic verification, malicious or compromised oracles could deliver false data to your contract.
You and your users take severe risks of being financially impacted by insecure and biasable RNG techniques.
