🎲Chainlink VRF v2

Verifiable, tamper-proof random number generator for blockchain gaming and NFT projects

Verifiable source of randomness

Chainlink VRF provides cryptographically secure randomness for your blockchain-based applications.

Provably random

Provably random, tamper-proof, and low cost randomness for smart contracts

Easily integration

Easily integrate verifiable randomness in your smart contract:

unit256 public randomResult;
function fulfillRandomness(uint256 requestId, unit256[] randomness) internal override {
      randomResult = (randomness[0] % 50) + 1;
}

Provably secure applications

Build provably secure blockchain-based applications with Chainlink VRF across multiple use cases:

Grow your reach

Grow your application’s reach with Chainlink VRF, a purpose-built RNG for smart contracts

Random number generation (RNG) for smart contracts

• 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

Provide your users with a more trustworthy experience

• 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

Provably-fair and verifiable randomness

• 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

Randomness on a massive scale

• 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
