At @AIAgentsSummit Berlin, developers built with Circle Agent Stack and explored what the agentic economy can look like in practice. We saw agents that could hold wallets, manage budgets, discover paid services, pay in USDC, and return receipts as part of the work they performed. → 25 unique submissions → Agent Wallet + x402 + Gateway payments → Real experiments in agentic commerce Here are the top projects that stood out: 🏆 Proprietor [Winning Project] An agent-run business using Circle Agent Wallet, Circle CLI, and x402 payments to earn revenue, pay supplier agents, manage margin, and return receipts. A great example of what autonomous companies could look like when agents control wallets. 🏆 BytomicProxy A pay-per-request proxy using the Circle Agent Stack starter kit, Agent Wallet, x402/Gateway payments, and spend ledgers to make APIs and infrastructure agent-payable. 🏆 402Cards An agentic commerce adapter using Circle Agent Wallet, ecosystem starter-kit components, and x402 payments to let agents buy items on mainnet through an agent-readable workflow. 🏆 giftr A local gift marketplace using Circle Agent Wallet, Circle Gateway, Arc Testnet, and x402 batching so agents can browse, choose, and pay for gifts with USDC. 🏆 SparkLead A recurring competitor-intelligence workflow using the Circle starter kit, Agent Wallet, and x402 payments so an agent can pay per insight and deliver research. The pattern was clear: The next wave of agents will not just generate answers. They will discover services, pay for what they need, coordinate with other agents, and return receipts. That is the agentic economy Circle Agent Stack is helping builders bring to life.
