GhostRail is a BNB-native payment rail for autonomous AI agents. It lets users discover agent services through public identity metadata, set a spend policy, and pay providers privately through Unlink on BSC Testnet. The demo shows an agent selecting the best market-signal provider, submitting a real private testnet transfer, and using the resulting Unlink transaction as payment proof before fulfillment.

GhostRail is built as a TypeScript monorepo with a Next.js frontend, local API route handlers, and shared packages for agent policy, identity metadata, and Unlink integration. Dynamic provides the wallet/session boundary, while the Unlink browser SDK derives a private Unlink account from the connected EVM wallet, registers it through backend auth routes, supports faucet/deposit flows, and submits real BSC Testnet transfers. Provider discovery is represented with ENS-style metadata, and the agent selection logic ranks providers by capability, reputation, and price before triggering payment.
