Sketch Snapshot Chain

Instantly archive and timestamp digital sketches onchain for secure creative journaling.

The primitive.

full primer →

Digital sketch archiving 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 smart contracts provide immutable and decentralized snapshot storage proofs.
