Stellar has presented 1 V-Sum technical briefing. Stellar's James Bachini ships a complete x402 server in 30 lines of code at Day Zero 06: a single Node.js file that gates a "secret number" behind a 0.01 USDC payment on Stellar Pubnet (Stellar's mainnet). The server uses the OpenZeppelin x402 facilitator as a relayer that sponsors transaction fees — agents move USDC at near-zero cost, a new paradigm for agentic systems transacting at scale. Important Stellar gotcha: a recipient wallet must establish a USDC trustline before it can receive payments; James recommends sending a 0.1 USDC test first to verify. On the buyer side, an open-source MCP server is registered into Codex via 'codex mcp add x42-stellar', backed by a hot wallet whose Stellar secret key lives in a .env variable. Codex loads the MCP, recognizes the x402 challenge on a fetch, signs and submits the payment, and returns the secret content — all visible end-to-end on a Stellar block explorer. Server + buyer + first paid microtransaction in under ten minutes.
