ArcPay

SDK for agentic commerce on Arc

Live siteRepository

Stack

  • TypeScript
  • Solidity
  • Arc
  • x402

Highlights

  • ·28 modules for agentic commerce
  • ·Payments, escrow, streaming, stealth in one SDK
  • ·Arc-native, composable with x402

Problem

Every agent-commerce project rebuilds the same four primitives (pay, escrow, stream, stealth) against subtly different interfaces. There is no shared SDK for Arc.

Approach

One TypeScript SDK, 28 modules, that wraps all four primitives behind a uniform agent-facing API. Drop it in, pick the flow, and it composes cleanly with existing x402 facilitators.

Outcome

Shipped and pinned on GitHub. Acts as the reference client library for Arc-side agent flows.
