HEARTHASH · x402

A pay-per-attestation protocol for touring musicians. Every track played or gear-interaction triggered during a live set is cryptographically signed and anchored to Base via a 0.01 USDC micro-fee. Fans pay a cent to verify the 'Live-ness' in real-time, and venues pay to verify setlist compliance. Payment acts as the signal that the audio wasn't just a pre-recorded playback.

The primitive.

full primer →

Access to the performance verification engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so musicians — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveTraditional performance verification is hindered by manual reporting and high friction. By turning every 'proof-of-play' into an x402 transaction, we create a continuous stream of low-latency, paid metadata. This transforms performance data into a liquid asset for royalty distribution and 'Verified Live' status for digital collectibles.
