How every spin stays fair: Pyth Entropy
Where your spin's random number comes from, why nobody can steer it, and how to check it yourself.
A prize wheel is only as fair as its randomness. PythWheel gets the random number for every spin from Pyth Entropy, which delivers random numbers on-chain in a way nobody can predict or manipulate — including the PythWheel team.
Why randomness is hard on a blockchain
Blockchains are deterministic: every computer on the network has to reach exactly the same result, so there's no natural source of chance. Values like block hashes look random, but whoever produces a block can influence them, so a contract that relies on them can be gamed.
How Pyth Entropy solves it
Entropy combines two contributions so that no single party controls the result:
- The randomness provider commits to its secret values in advance, publicly and on-chain, so it can't change them later.
- When you spin, the PythWheel contract requests a random number from Entropy. The request adds a value the provider couldn't know when it committed.
- The provider then reveals the matching secret. The Entropy contract checks it against the commitment, combines the two, and delivers the result to PythWheel.
- PythWheel uses that number to pick your prize from the published drop rates.
What that means for you
- Nobody can pick winners — the number decides.
- A spin can't be re-rolled: once its number is delivered, the prize is fixed.
- Anyone can verify the number after the fact.
Check it yourself
Look up your spin transaction on a block explorer such as HyperEVMScan, then find the request in the Pyth Entropy Explorer to see the random number it received.
