BrushBot · Paid Certificate

BrushBot meters every AI-assisted refinement, texture layer, and brush stroke as a discrete EIP-3009 micro-settlement. Stop paying for monthly SaaS subscriptions you don't use; pay only for the exact latency and compute consumed by your digital canvas. High-fidelity diffusion calls are gated by instant Privy-signed auth, turning the act of painting into a real-time stream of provenance-backed micro-transactions. 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 AI-assisted painting 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

BrushBot
Integrate AI painting tools powered by gasless onchain user verification and transactions. 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.
