USDC payment rails for AI-native products on Arc.

A self-hosted proof-of-work demo showing how AIIV plans to use Arc and Circle App Kit for stablecoin payments, bridge routes, swaps, and unified balances.

Deployment target

arc.aiiv.me

Isolated VPS service on 127.0.0.1:3100, proxied by Caddy with automatic HTTPS.

MVP flow

Payment request first, execution after review.

The first version intentionally separates the public web UI from the transaction executor. App Kit examples use blockchain adapters that can be backed by private keys; this demo keeps that signing boundary server-side instead of placing secrets in the browser.

01Connect intent

Collect recipient, token, amount, and preferred Arc route.

02Estimate

Use App Kit quote/estimate APIs before any transaction is sent.

03Execute safely

Run signing through a controlled server-side executor.

04Track status

Surface transaction hash, route status, and completion state.

MVP focus

USDC Send

A safe payment request flow that prepares same-chain USDC sends without exposing private keys in the browser.

Next

Bridge

Arc Testnet routing for cross-chain USDC movement through Circle App Kit bridge primitives.

Next

Swap

Stablecoin swap quote and execution flow powered by Circle's App Kit swap interface.

Planned

Unified Balance

A single USDC balance experience across supported chains, with Arc as the payment destination.

Proof package

What this demo proves for Build on Arc.

Roadmap

From demo to production workflow

Phase 1

Ship the public site, README, and Build on Arc application proof.

Phase 2

Add a server-side App Kit executor for testnet USDC send estimates.

Phase 3

Expand to bridge, swap, unified balance, and AI agent payment flows.
