Smart Contract Audio RNG

Use onchain randomness to generate unique, verifiable generative music pieces as NFTs.

Hedera smart contract (HSCS)· onchain logic
Section · Onchain

The primitive.

full primer →

Generative music gets a tiny Solidity contract deployed to Hedera testnet through the JSON-RPC relay; musicians see a 'verified onchain' badge with the live address and a one-tap HashScan link.

Why this primitiveHedera testnet’s secure RNG enables trustable generative outputs onchain.
