Art Swap Protocol

Create a trustless platform for artists and collectors to swap artworks instantly onchain.

Hedera smart contract (HSCS)· onchain logic

The primitive.

full primer →

Peer-to-peer art exchange gets a tiny Solidity contract deployed to Hedera testnet through the JSON-RPC relay; painters see a 'verified onchain' badge with the live address and a one-tap HashScan link.

Why this primitiveHedera testnet contracts enable atomic swaps guaranteeing secure, simultaneous asset exchanges.
