Builder reference templates

Turn ecosystem signal into repeatable product templates.

Arc Blueprints converts Radar research into buildable templates for the strongest public Arc patterns: payments, agentic x402, escrow, stablecoin FX, machine payments and private invoices.

Templates

Six reference flows from the Arc builder map.

Each blueprint names the observed ecosystem pattern, the Arc Suite modules that implement it, and the shortest path from static demo to pilot-ready MVP.

Payments

USDC Checkout

Arclet / ArcPay pattern

BillingWallet OSFlowPrivate
  1. Create payment intent
  2. Screen recipient
  3. Collect USDC
  4. Issue scoped receipt

Build cadence

Every template follows the same launch path.

Day 1Static template

Product page, data model, fixture data and smoke coverage.

Day 3Live API path

Supabase tables, API route, scoped workspace key and audit rows.

Day 7Settlement path

Circle wallet or provider execution, idempotency and webhook reconciliation.

Day 14Pilot handoff

Demo workspace, analytics event, investor proof and release note.

Primitive map

Circle and Arc primitives become implementation blocks.

Circle WalletsCustody, signing, recovery and wallet lifecycle
x402 / GatewayPay-per-request API access and receipts
CCTP / StableFXCross-chain and multi-currency settlement patterns
Gas Station / PaymasterSponsored transactions and agent-level gas controls
Compliance EngineScreening signal before private or public value movement
SupabaseAudit log, sessions, leads, monitor and pilot state

Investor proof

Blueprints make Arc Suite feel expandable, not scattered.

The project now has a visible mechanism for adding new products from ecosystem demand: Radar finds the pattern, Blueprints standardizes it, then Flow, Billing, Shield, Private, Wallet OS and Ops turn it into a pilotable module.
