PromptForge Marketplace Design

PromptForge is a marketplace where prompt engineers and AI creators can own, trade and monetize AI prompts and agents with automated, transparent on-chain royalties.

The core challenge was designing trust and ownership in a new market standard from discovery to creation and monetization while keeping the experience accessible to non-crypto users.

The AI prompt economy was growing fast but lacked core infrastructure:

No verifiable ownership → prompts could be copied or resold without attribution

Opaque royalties → creators had no clarity on earnings or reuse

High entry friction → Web3 onboarding required wallets and blockchain knowledge

Result: creators were under-monetizing or avoiding the space entirely.

PromptForge introduces a marketplace where:

Ownership is verifiable on-chain

Royalties are automatic and transparent

Users can explore without needing a wallet

The design had to balance:

Trust → transparent ownership history

Fairness → 90/10 creator-first revenue split

Accessibility → frictionless onboarding for non-crypto users

Existing tools (PromptBase, GPT Store, OpenSea) each solved part of the problem but not all:

PromptBase → simple marketplace, no ownership layer

GPT Store → closed ecosystem, limited monetization

OpenSea → strong ownership, weak AI-native UX

PromptForge bridges marketplace usability with blockchain ownership, without exposing complexity.

Designed around three user types:

Curious visitors

Buyers

Creators

Core flow: Land → Understand → Browse → Create → Earn

Key Design Decisions

Product-first hero using a real prompt card instead of abstract messaging

Problem/solution split for clarity and contrast

Early placement of social proof for trust

Simple donut chart to communicate 90/10 tokenomics visually

Dark UI chosen to align with AI + Web3 culture and improve contrast for CTAs

Accent colors used to highlight pricing, status, and actions

3-column grid + filter sidebar

Filters based on user behavior (category, price, rating, availability)

Inline reputation and sales data to reduce trust friction

Results count placed near content for clarity

Info – title, category, prompt type

Content – model + prompt with variables

Config – pricing + variable setup

Preview – final review before publishing

Publish – on-chain mint

Designed to reduce complexity into small, reversible steps and improve confidence at each stage.

Landing page: product-led storytelling with modular sections

Marketplace: comparison-first browsing experience

Creation flow: structured wizard for low cognitive load

App view: condensed navigation with key platform stats upfront

Reduced onboarding friction with no-wallet exploration

Made creator economics (90/10 split) visually intuitive

Simplified complex prompt creation into a guided flow

Embedded trust signals throughout the browsing experience

Balancing two audiences (new users vs. Web3 creators) through layered information

Communicating blockchain value without technical overload

Improving empty states in preview and marketplace components

Ensuring marketplace cards scale with real-world content variability
