Frequently Asked Questions
Get clear answers on how our verifiable randomness service works for dynamic NFT traits, from integration to security.
Our service provides on-chain verifiable randomness (VRF) as a secure off-chain data feed. When your smart contract requests a random number for a trait reveal or mutation, our decentralized network of nodes generates a random value and cryptographic proof. This proof is submitted on-chain with the result, allowing your contract to verify the randomness was generated fairly and was not manipulated, ensuring provably rare traits.
