The primitive.

full primer →

Event verification 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 smart contracts provide immutable proof of player interaction and eligibility.
