Quantum computing introduces long-term risks for blockchains, digital assets, and financial infrastructure. Circle's Post-Quantum Security Roadmap outlines how Arc is approaching post-quantum resilience through a phased roadmap across onchain and supporting systems.

Join us for a demo day featuring recent hackathon winners building AI, agentic payment, and nanopayment-related projects on Arc and Circle infrastructure. Each team will share a short demo of what they built, how it works, and how Arc / Circle infrastructure supports the use case. The session will highlight real builder projects across agentic commerce, micropayments, onchain intelligence, and emerging AI-enabled workflows. Featured teams include: Vertex, Gyasss, Cairn, and MEV Shield. The goal is to give the Arc House community a practical look at what builders are already creating on Arc, and to surface new ideas for the next wave of AI and agentic commerce. --- Arc is offered by Circle Technology Services, LLC (“CTS”).

TLAY is building embedded wallet and trust infrastructure for machine-to-machine commerce. In this session, Leo will walk through a physical demo where an eCandle solar energy device broadcasts changing electricity prices and a Bitaxe miner decides whether to buy power every 10 seconds. When the price is profitable, the miner signs a USDC payment authorization on-device, consumes electricity, and the payment flow is later settled through Circle infrastructure on Arc Testnet. The session will help builders understand how machine wallets, nanopayments, and Arc can extend on-chain payments from cloud agents into real-world connected devices. --- Arc is offered by Circle Technology Services, LLC (“CTS”).
