PROOFSTACK · Paid Certificate

A peer-to-peer ledger for creative consensus. Pay $0.10 to commit a new layer, revision, or documentation log to the permanent collaborative stack. Only paid entries are pinned to the collective IPFS manifest, ensuring every addition to the group record is intentional and stake-weighted. Settlement happens instantly via Base, turning the art archive into a funded, immutable provenance engine. Paying 0.01 USDC over x402 returns a signed provenance certificate for the work.

The primitive.

full primer →

One 0.01 USDC payment turns the group project documentation record into a signed certificate painters can email, attach or archive — and the page proves who signed it without asking anyone to trust the server.

Why this primitiveLoading details…

Kernel
a 0.01 USDC payment over x402 that returns a relayer-signed provenance certificate over the WOTS+ head — a portable document anyone can verify without trusting the issuer
Drives the UI as
a certificate card with the signed fields, the issuing signer, and a 'recover signer' check that runs in the browser

Collaborative Art Archive
Pin shared artworks and process files to IPFS for permanent collaborative history storage. Ownership is sealed inside a post-quantum QUIP vault.
generative art minting
Gen-Seed · Paid Certificate
Instead of a heavy upfront minting fee, users pay per 'Evolution Sign-off.' Artists deploy logic; collectors pay per high-fidelity render, receiving a Base tx hash as proof of unique generation. The payment is the shutter click. Paying 0.01 USDC over x402 returns a signed provenance certificate for the work.
artwork license management
Atelier · Paid Certificate
A high-frequency licensing gateway where digital assets are metered by the millisecond. Each glance or API call triggers an EIP-3009 transfer, returning a Base tx hash as a cryptographically verifiable proof-of-usage. Paying 0.01 USDC over x402 returns a signed provenance certificate for the work.
programmable artwork framing
BORDERLINE · Paid Certificate
A programmable border-engine where every aesthetic shift is a transaction. Use the QUIP primitive to meter 'Gaze-Based Evolution' (auto-shifting frames based on how many wall-clocks pass) or 'Oracle-Linked Skins' (weather/price/time-of-day) where each asset state-change is a paid, verifiable event. Pay to re-frame your collection for a specific gallery mood. Paying 0.01 USDC over x402 returns a signed provenance certificate for the work.
