We 💙 AI Agents at Arc.  If you're building with Autonomous Agents, tell us about it here in a post.

Agentic Commerce on Arc

> What if AI intelligence was paid for per use, verifiable on-chain, and grounded in real data — not hallucinations?

Paymind is an on-chain–gated AI system (X402) where: 

• Access is enforced using the X402 pattern

• Gemini 3 only runs after on-chain payment is confirmed

To make this practical, each user creates an agent wallet.

The agent wallet holds funds and executes payments programmatically, so users do not sign a transaction for every AI request. Once funded, execution happens autonomously within limits.

No subscriptions. No blind trust. No repetitive signing.

Paymind analyzes real, structured product data sourced from an external API (DummyJSON during the prototype phase).

Although DummyJSON is used for testing, the data is: 

• Fully structured (pricing, descriptions, reviews, metadata)

Gemini 3 reasons strictly over this data to produce: 

Paymind also delivers paid crypto analysis using live and historical market data, including: 

• Market structure & multi-timeframe alignment

• Invalidation logic & confidence scoring

Users unlock structured trade context — logic, not predictions.

All AI execution is gated by on-chain payment via the agent wallet.

Low-latency execution – Enables real-time verification of pay-per-request AI without slowing the user experience

Low transaction costs – Makes frequent, small USDC payments practical for AI inference

Agent wallet support – Allows autonomous wallets to execute payments without repeated user transaction signing

Reliable RPC infrastructure – Prevents UX-breaking delays during payment verification and AI execution

Native fit for X402 – Cleanly enforces on-chain access control for AI services

Programmable settlement – Treats each AI request as a verifiable on-chain action, not an off-chain promise.

Most AI tools lock users into subscriptions or require blind trust.

Paymind tightly couples payment, access, and inference, ensuring AI only runs when value is explicitly paid for — and verifiable on-chain.
