Mapping the technical evolution of the OFFER-HUB ecosystem, from core engine to global marketplace templates.
Ecosystem structure
This showcase turns escrow automation, vault custody, and payout sequencing into a flow you can read at a glance. OFFER-HUB ingests fiat or crypto, passes value through programmable escrow logic, and releases seller settlement only after the SDK state machine advances through its guarded checkpoints.
Input rails
Fiat / Crypto
Custody core
Escrow + Vault
Settlement
Seller release
Normalize buyer input, verify custody accounts, and initialize the escrow envelope.
Confirm bridge liquidity, approve trustline movement, and lock release rules.
Settle to the seller, persist final state, and expose the payout event downstream.
Trust boundary
Every transfer is wrapped in encrypted instructions and isolated account contexts before funds ever reach the settlement path.
Bridge + settlement rail
Trustlines and vault balances let OFFER-HUB route value from fiat on-ramp or crypto deposit into a stable USDC settlement layer.
State machine control
A granular SDK state machine coordinates escrow creation, approval, dispute handling, and release with explicit transitions.
The SDK turns complex backend choreography into a small set of explicit method calls and irreversible checkpoints.
The Marketplace Template is the official frontend boilerplate that connects directly to the Orchestrator—giving you split Buyer and Seller experiences out of the box.

↳ Scaffolds a full marketplace with Buyer & Seller routes, escrow hooks, and the @offerhub/sdk pre-configured.
@offerhub/sdk
The official JavaScript/TypeScript SDK
The @offerhub/sdk bridges the Marketplace Template and the Orchestrator. It exposes typed hooks for escrow lifecycle management, real-time payout tracking, and asset resolution — so your frontend stays synced with the payment engine without writing a single REST call by hand.
