Very Randomifier Function.
Give your Solana app a number that changes with the market.
Randomifier combines seven cryptocurrency prices into one number. Your app can use it to vary an artwork’s colors, a digital world’s weather, or another feature you build. When the prices change, the result can change too.
Live on Solana mainnet. Free to call. More chains coming.
Saved example · October 14, 2026
Change a price. See the result.
Move the slider to adjust one of the seven saved prices. The other six stay the same. This shows the calculation your app can call.
The same prices always give the same result.

For developers
Use it in your app.
Make a call, receive the number, and decide how it affects your app. You also receive a fingerprint of the prices used, so you can check the inputs.
JavaScript / Node.js
Download the ready-to-run reader. It checks the mainnet program and simulates a call without connecting a wallet.
Run the JavaScript example →Your Solana program
Use the Rust helper to call Randomifier from your own program and read the result in the same transaction.

Free from Uncle Matt.
Randomifier charges $0 in service fees. A standalone, one-signature Solana transaction has a base fee of 0.000005 SOL, plus any priority fee. The supplied JavaScript reader simulates a call and pays no on-chain transaction fee.
