# Cash Stash Raffles

### CS Raffles Explained

Cash Stash Raffles are *monthly events where participants can win cash prizes*. To join, users need to hold or stake special NFTs called "[Coca NUTZ](/book-of-askobar/our-ecosystem/askobar-zoo/liquid-staking/staking-rewards-boosts/coca-nutz-721-nfts.md)." These NFTs not only boost staking rewards but also give entry into the raffles, offering a fun way to earn extra rewards.

### CS Raffles VRF

Cash Stash Raffles use a ***Verifiable Random Function*** (VRF) to ensure fair and transparent winner selection. Here's how it works:

1. <mark style="color:yellow;">**Participation**</mark>: Users join the raffles by holding or staking "Coca NUTZ" NFTs.
2. <mark style="color:yellow;">**Random Selection**</mark>: The VRF generates a random number to select winners, ensuring the process is unbiased and tamper-proof.
3. <mark style="color:yellow;">**Transparency**</mark>: The random number and winner selection process can be verified by anyone, ensuring complete transparency.

In simple terms, VRF makes sure the raffles are fair, and everyone has an equal chance of winning based on a truly random and verifiable process.
