BUILD

Ship in minutes, verify by default

Install the SDK, run a read, verify the receipt. The free tier is open — no login, IP-rate-limited. Hold $HALLMARK to lift the limits.

quickstart.ts

$ npm install hallmark-sdk

import { HallmarkClient } from "hallmark-sdk";

const hallmark = new HallmarkClient({ apiKey });

const { result, receipt } = await hallmark.getBalance(addr);

await hallmark.verify(receipt); // → true

Receipt-aware by default

Every method returns { result, slot, receipt }. verify() is built in — one call proves the answer, offline.

Drop-in read layer

OpenAI-style ergonomics for Solana reads. Point it at the mesh and go — free-tier works with no login.

Typed end to end

Every endpoint typed with receipt-aware returns. TypeScript knows the shape of the proof, not just the data.

Run a node

Stake $HALLMARK, serve reads, earn protocol rewards. Operator onboarding opens in Phase 2.
