@samconnerone This energy is everything @samconnerone! Feels exactly like early days of something massive. Arc House is the place to be right now - so many builders shipping, so much momentum

[Torin @Torin_559]

@samconnerone Prompts all the way - especially when powered by Arc stablecoins. Seeing more builders move to real agentic loops every day.

[Torin @Torin_559]

@bobbilee Absolutely love this thread @bobbilee! The shift from old-school devrel to agentic infrastructure is spot on. Arc is perfectly positioned to lead this new era.

[Torin @Torin_559]

🧠 I Found a Missing Piece of the Arc Economy

For months, I kept asking myself a simple question:

If AI Agents are going to become the largest economic actors on-chain, where will they actually work, collaborate, and pay each other?

After building, testing, and pushing Arc's infrastructure to its limits, I believe I have found one missing piece of that future.

TRANSCENDING THE AGENTIC ECONOMY:

Why We Built the AI Agent Co-Working Space on Arc Network

The Agentic Economy is no longer a prediction for 2026.

It is already happening.

Autonomous AI agents are researching markets, generating content, analyzing data, negotiating services, and increasingly making economic decisions without direct human intervention.

Yet there is an uncomfortable truth that much of Web3 still ignores:

Traditional L1 and L2 blockchains were never designed for AI-native commerce.

When AI agents execute millions of tasks, perform high-frequency deep searches, and continuously consume APIs, volatile gas fees and signature-heavy wallet experiences become a scalability nightmare.

AI does not need manual approvals.

AI needs frictionless capital.

AI needs predictable costs.

AI needs money that moves in real time.

That realization led me to build AI Agent Co-Working Space - an autonomous workspace designed specifically for the next generation of AI-powered economic activity, fully powered by Arc Network's infrastructure.

👉 Live Demo: https://t.co/iSZ5gK6L6N

👉 Open-Source Repository: https://t.co/WXG7U4r6ix

🛡️ Architecture Highlights & Technology "Wow Moments"

This is not a static dashboard.

It is a functional demonstration of how Arc's core protocols can empower multiple specialized AI agents (Alex — Research, Luna — Writer, Kai — Designer) to operate as a coordinated autonomous workforce.

1. Real-Time Pay-Per-Second Economics

Powered by Arc Nanopayments

Instead of outdated subscription models, AI Agent Co-Working Space uses Arc Nanopayments to stream value continuously between participants.

A session budget is consumed in real time and routed directly to the active agent's wallet at sub-cent precision (~$0.0008 USDC/sec).

When Alex finishes collecting RWA intelligence and hands the task to Luna for content creation, payment streams automatically stop, reroute, and continue flowing to the next worker without any manual intervention.

The economic layer becomes as autonomous as the agents themselves.

2. Automated Circuit Breaker Protection

What happens when an AI agent enters an infinite loop?

What if malicious prompts trigger excessive API consumption?

On most networks, your treasury could be drained within minutes.

To solve this, the Nanopayments Coordinator acts as a financial guardian.

The moment spending reaches predefined safety thresholds, the system automatically triggers a Circuit Breaker, immediately freezing all active payment streams and switching agents into a visible:

⚠️ BUDGET EXCEEDED

state.

This creates a self-protecting financial layer capable of defending autonomous operations without human intervention.

3. Frictionless Onboarding with Arc AppKit SDK

User experience remains one of Web3's greatest challenges.

Arc AppKit SDK removes much of the underlying blockchain complexity.

Users connect wallets, manage on-chain identity, allocate resources, and replenish budgets through a seamless One-Click Refill workflow.

Funds are added instantly.

Agents resume operation automatically.

The AI production pipeline continues uninterrupted.

No endless MetaMask popups.

No approval fatigue.

No unnecessary friction.

🔮 RWA 2026 Vision:

When Infrastructure Meets Autonomy

The future of Real World Assets is not simply tokenizing static assets.

The real opportunity emerges when autonomous agents can:

• Hire other agents on demand

• Audit tokenized real estate agreements

• Produce and distribute marketing campaigns

• Purchase data and intelligence services

• Negotiate digital work

• Settle payments instantly through stablecoin-native infrastructure

All without requiring human coordination.

Arc Network's AI-first infrastructure combined with stablecoin-native financial rails could become the foundation for billions of dollars of autonomous economic activity operating continuously, 24/7.

This project is fully open source and represents my contribution toward building the future Agentic Economy.

Feedback, ideas, and contributions from fellow builders are always welcome.

Successfully integrated Circle Agent Stack into my workflow 🔥
After a smooth setup process, I now have a fully functional custom PowerShell Dashboard that seamlessly controls the entire Circle Agent Stack.
Key achievements so far:

✅ Created and managed Agent Wallets via CLI
✅ Deposited into Gateway and monitored real-time balances
✅ Successfully tested Nanopayments on Arc Testnet
✅ Discovered & paid for services through the Agent Marketplace using x402 protocol
✅ Built a clean, interactive dashboard for wallet ops, history, transfers, and micropayments

The developer experience is impressive — from zero to having a programmable agent wallet capable of autonomous micropayments in under 40 minutes. The combination of Circle CLI + Gateway + Nanopayments feels like a real step forward for the agentic economy.
Extremely bullish on this infrastructure. Now preparing to move to mainnet and explore more advanced agent use cases.
Huge thanks to the Circle team! 👏

First Steps with Arc Testnet: Building a Real On-Chain Payment Demo with Circle Agent Stack

Cross-posted from my dev journal — sharing for developers exploring Arc Testnet and the Circle CLI.
TL;DRI built a complete hands-on payment demo on Arc Testnet (Chain ID: 5042002) using the Circle Agent Stack CLI in a single afternoon. From wallet setup and USDC transfers to Gateway deposits and USDC→EURC swaps — all executed with full transparency, including commands, gotchas, and on-chain transaction hashes.
Setup: Circle CLI in Under 5 Minutes
Bash
npm install -g @circle-fin/cli
circle --version # v0.0.3
Important note: The correct package is @circle-fin/cli (not @circle-fin/agent-cli).
Login uses email OTP:
Bash
circle wallet login [email protected] --testnet
Agent Wallet on Arc Testnet
Bash
circle wallet list --chain ARC-TESTNET
Agent Wallet Address: 0x9699735572d96cdb448cd95b9ed15de2cdc26dce
Funded with 100 testnet USDC via Circle faucet. This is a smart contract wallet — gas is paid natively in USDC, no ETH required.
Demo 1: USDC Transfer
Always estimate first:
Bash
circle wallet transfer 0x000000000000000000000000000000000000dEaD \
--amount 1 \
--token 0x3600000000000000000000000000000000000000 \
--address 0x9699735572d96cdb448cd95b9ed15de2cdc26dce \
--chain ARC-TESTNET --estimate
→ Estimated fee: 0.041168 USDC
Execution:
Bash
circle wallet transfer 0x000000000000000000000000000000000000dEaD \
--amount 1 \
--token 0x3600000000000000000000000000000000000000 \
--address 0x9699735572d96cdb448cd95b9ed15de2cdc26dce \
--chain ARC-TESTNET --quiet
TX: 0xfab393d6ad78f4e004bb760831ce742bd3dd6cfcc44d0ee0df1e4a0b1df9313f → View on ArcScan
Demo 2: Gateway Deposit (for x402 Micropayments)
Bash
circle gateway deposit --amount 2 \
--address 0x9699735572d96cdb448cd95b9ed15de2cdc26dce \
--chain ARC-TESTNET
TX: 0xacb81d3c4159f8c2fac424cd8a371c5fa921f4482c5eb9dcac53b83730d50281
Balance confirmed: 2.000000 USDC in Gateway.
Demo 3: USDC → EURC Swap
Quote:
Bash
circle wallet swap USDC 2 EURC --chain ARC-TESTNET --quote
Execution (with 1% slippage):
Bash
circle wallet swap USDC 2 EURC 1.99 \
--address 0x9699735572d96cdb448cd95b9ed15de2cdc26dce \
--chain ARC-TESTNET \
--slippage-bps 100
Result: 2 USDC → 1.992919 EURC (two transactions: approve + swap).
Key Contract Addresses (Arc Testnet)
USDC: 0x3600000000000000000000000000000000000000
EURC: 0x89b50855aa3be2f677cd6303cec089b5f319d72a
GatewayWallet: 0x0077777d7EBA4688BDeF3E311b846F25870A19B9
Insights on x402 Micropayments
The CLI includes a built-in service marketplace (circle services search) with 40+ paid APIs (crypto prices, stocks, SEC filings, Kalshi, Perplexity, etc.), payable in USDC micropayments.
Current limitation: Most services are not yet live on Arc Testnet (ETH, Base, Arbitrum supported). Arc support is expected soon.
Lessons Learned

Always run --estimate before transfers and --quote before swaps.
Set up the Gateway deposit early if you plan to use x402.
Paying gas in USDC is a genuine UX breakthrough for agent wallets.

Double-check package names — small details matter.
The Circle CLI is clean, well-designed, and production-ready once you get past the initial setup.
What’s next:
Test CCTP bridging from Arc Testnet

Live x402 micropayment calls once Arc support lands
Custom contract execution via circle wallet execute
Happy to answer questions if you're getting started on Arc + Circle. The combination of agent wallets + USDC-native fees feels like the future of on-chain payments.

✅ Claim confirmed on-chain

Here's the full breakdown 🧵

— Contract verified
📄 Smart contract deployed & source verified:
Contract: 0x278C722DFefAE93E6864339962D4a22ca659E522Network: Arc Testnet → https://t.co/ek0GMR7qwh

253 lines of Solidity: → openChannel (payable) → claim with ecrecover on-chain → reclaimExpired → protocol fee 0.5% → double-spend protection

— On-chain proof
⛓️ Real on-chain proof — not fake:

✅ Claim confirmed at block 41776885
✅ Claim tx: 0x4facc97141d55a4509132bcacedfabfba10675ad880bd896f0ef24846910fb67
✅ 10 seconds streamed = 0.001000 USDC paid automatically
✅ Provider received funds on-chain
✅ Client refund sent back by contract
No trust. No intermediary. Smart contract handles everything.

— Architecture.
🏗️ Full 3-tier architecture:
① StreamPayment.sol (253 lines) State channel, ecrecover verification, auto-refund
② server.js (584 lines) WebSocket state machine, tick every second, auto-claim on disconnect
③ React dashboard (live) Real-time payment meter, sparkline, OKX/MetaMask integration
All 3 running simultaneously. End-to-end verified.

— Why ARC ?
🔵 Why @arc is perfect for this:

→ USDC native gas = predictable payment amounts → Fast finality = 1-second ticks without lag → EVM compatible = Hardhat + ethers.js + MetaMask → Circle native = real USDC, not wrapped

Pay-per-second streaming isn't cleanly possible on ETH mainnet. ARC is literally designed for this.

— Use cases
💡 What this unlocks on ARC:
→ Pay for AI per token generated → Pay for API per request, not per month → Pay for bandwidth per KB → Pay for compute per second
Zero subscriptions. Zero overpaying. This is the economic primitive Web3 has been missing.

@arc Just shipped a full Pay-per-Second streaming payment system on
@arc
testnet.

Not a mockup. Not a fork.
