cc-vrf

What problem does it solve?

cc-vrf replaces opaque or centralized randomness with verifiable on-chain random draws for Solana applications, so users can audit every outcome after the fact.

Core Features & Use Cases

• Permissionless VRF workflow: Register and freeze an operator authority, then commit ECVRF proof hashes on chain for later verification.
• Multiple commitment modes: Use compressed PDA registry commits, registry commits with beta for on-chain consumers, or event-only commits for lower cost.
• Developer tooling: Integrate the TypeScript SDK to build commits, verify authority lifecycle, scan events, and reproduce deterministic random streams.
• Use cases: Ideal for dice games, NFT trait assignment, raffle selection, loot drops, lottery draws, and validator or committee selection.

Quick Start

Add cc-vrf to your Solana project when you need low-cost, publicly verifiable randomness that can be committed on chain and independently checked later.
