Proof of Stroke · x402
$0.01 — pay-per-revision. Eliminate the friction of 'half upfront' deposits. Artists publish gated progressive layers (sketches, linework, flats) that patrons unlock instantly via HTS transfer. Every feedback loop or high-res export is a micro-settled transaction on Hedera testnet. Payment becomes the heartbeat of the creative workflow, protecting the artist's time while giving the patron an 'undo' button at any milestone.
The primitive.
Access to the commission workflow management engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so painters — or the agents working for them — pay per query and get a HashScan receipt every time.
Why this primitiveTraditional commission models suffer from trust-fall dynamics. By turning the workflow into a series of x402-gated micro-deliverables, the artist is paid for every minute of labor, and the patron pays only for progress they approve.
