Section · Onchain

The primitive.

User-generated content gets a tiny Solidity contract deployed to Hedera testnet through the JSON-RPC relay; game designers see a 'verified onchain' badge with the live address and a one-tap HashScan link.

Why this primitiveHedera testnet's verified contracts facilitate trust in player-created asset ownership.
