Why ChainVRF?

🔒 Cryptographic VRF

Each oracle node generates randomness using cryptographic primitives (keccak256 + secret), combined with on-chain seed for tamper-proof results.

⚡ Fast Fulfillment

Oracle nodes poll every 15 seconds. From request to on-chain fulfillment in under 30 seconds.

💰 1000x Cheaper

Chainlink charges $4-30 per request. We charge fractions of a cent. Same security, fraction of the cost.

🔍 Fully Verifiable

All randomness generation is recorded on-chain. Anyone can verify — seed, responses, XOR combining, final result.

🛡️ Staking Security

Oracle operators stake MATIC as collateral. M-of-N threshold support for distributed trust.

🔧 Easy Integration

Implement IRandomnessConsumer, call requestRandomness, receive your callback. Three functions.
