JACK Whitepaper v1.0.2

Intent-first execution with policy-enforced settlement

JACK turns high-level intents into verifiable execution plans: solver competition off-chain, routing via infrastructure like LI.FI, and settlement-time guardrails through programmable Uniswap v4 hooks.

Actual Setup Flow

Use the same dev topology as the MVP demo: landing, dashboard, and docs running together.

  1. Install dependencies: pnpm install
  2. Start all apps: pnpm dev:all (3000/3001/3002)
  3. Run contract checks: pnpm contracts:test before demo recording

Architecture at a glance

The docs map directly to the v1 whitepaper scope: intent format, solver coordination, routing controls, and policy-enforced settlement.

Kernel Layer

Deterministic execution lifecycle

Run intents through explicit states with fail-closed outcomes: CREATED → QUOTED → EXECUTING → SETTLED/ABORTED/EXPIRED.

Routing Layer

Best-effort routing with controls

v1 uses external routing infrastructure (for example LI.FI) behind allowlists, value caps, and explicit failure handling.

Settlement Layer

Policy enforcement at settlement time

Uniswap v4 hooks act as policy agents to enforce slippage bounds, min-out guarantees, and access control directly on-chain.

SDK & Integrations

TypeScript SDK with routing integrations

Use the TypeScript SDK to create intents, manage execution, and integrate with routing providers like LI.FI and Yellow Network.
