How it works under the hood

A simplified view of the smart contract interactions orchestrated by OFFER HUB APIs.

Developer Hub

Integrate in minutes,
not weeks.

The @offerhub/sdk mirrors your orchestrator state with a small set of explicit method calls — escrow creation, vault funding, and milestone release in three lines.

DocsSee Full API Reference

Order creation and escrow funding on the server side.

import { OfferHub } from "@offerhub/sdk";

// Initialize SDK — The Orchestrator mirrors your backend state
const oh = new OfferHub({ apiKey: process.env.OFFERHUB_API_KEY! });

// Order Creation: single call creates an escrow-safe payment intent
const order = await oh.orders.create({
  buyer:  "did:stellar:GCLIENT...",
  seller: "did:stellar:GFREELANCER...",
  amount: 1500,
  asset: "USDC",
  milestones: [
    { title: "Initial Delivery", percentage: 50 },
    { title: "Final Review",     percentage: 50 },
  ],
});

// Escrow Funding: lock funds on-chain — buyer wallet is debited
await oh.escrows.fund(order.id, {
  walletId: "wallet_01HKXYZ...",
});

import { OfferHub } from "@offerhub/sdk";

// Client-side SDK use a public/restricted key.
const oh = new OfferHub({
  apiKey: "oh_demo_xxxxxxxxxxxx",
});

// Milestone Approval: release partial funds to the freelancer.
// The Orchestrator validates completion and triggers on-chain
// settlement — mirroring the state machine from the server side.
await oh.orders.approveMilestone(
  order.id,      // orderId    — references the escrow envelope
  milestoneId,   // milestoneId — specific deliverable checkpoint
);
