VerseVault · x402

A locked-box narrative engine. Recipients pay a 0.01 USDC micro-transit fee to decrypt and 'unseal' poetry gifted to them. Every reading event triggers a provenance update, turning the act of gifting into a persistent, metered interaction where the sentiment is secured by the chain and the access is governed by the x402 protocol.

The primitive.

full primer →

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

Why this primitiveBy shifting from a one-time 'purchase' to a pay-per-reveal model, we turn a static poem into a recurring ritual. The x402 layer ensures that the creator or gifter can meter the experience, ensuring only the intended signatory can ‘unlock’ the verse through a micro-transaction.
