Build

Practical guides for building on NorthStar — integration, custom economics, production deployment.

This section covers what you need to ship a NorthStar integration. The Concepts section explains the formal model; this is the production-side counterpart.

In this section

• Integration Guide — adopt NorthStar in an existing Solana program. Covers the program-side delegate_to_portal hook, client wiring, runtime steps, the Mach AMM worked example, common gotchas, and a testing checklist.

• Programmable Economics — the full FeeStructure surface area. Custom fee tokens, per-instruction schedules, operator revenue capture.

When to use what

• If you're standing up a new project, start with Hello World, then come here for production-grade fees + delegation patterns.

• If you have an existing Solana program, the Integration Guide is the entry point.

• If you're building an aggregator or wallet that opens grids on behalf of users, Programmable Economics covers the revenue-capture model.
