Relay API

The Relay / Sponsor Service is the component that builds and submits transactions requiring server participation: account activation, reserve sponsorship, trustline enablement and sponsored fees.

Role

• Receives requests from the Control Plane (Pollar API) after validating policy and wallet state.
• Builds transactions (create account, set trustline, manage data, etc.).
• Coordinates with the Signer Boundary for sponsor key usage.
• Submits transactions to Horizon/RPC.

Usage from the app

From the developer integrating the SDK, the Relay is not called directly: the flow goes through @pollar/core and the Pollar API. The Relay is a backend service operated by the Pollar team.

Replace this content with internal endpoint docs or the API the Control Plane uses to talk to the Relay when that documentation is available.
