Knoww

A prediction markets platform to Know your Odds, powered by Polymarket.

Features

• Real-time market data from Polymarket
• Multi-wallet support via Reown AppKit
• Browse by categories: Politics, Sports, Finance, Crypto
• Event and market detail views with price charts
• Internal paper-trading agent dashboard and admin APIs
• Edge deployment on Cloudflare Workers

Quick Start

Prerequisites

• Node.js 20.19+ (or 22.x)
• pnpm
• Reown Cloud Project ID

If you plan to work on apps/agent, use a current Node.js release that supports node --experimental-strip-types for that package's test script.

Setup

# Install dependencies
pnpm install

# Seed the Next.js environment file used by `pnpm dev:web`
cp apps/web/.env.local.example apps/web/.env.local

# Seed the Wrangler/Worker environment file used by `pnpm preview`
# and by local Cloudflare-style bindings such as D1/cron vars
cp apps/web/.dev.vars.example apps/web/.dev.vars

# Add required local variables
$EDITOR apps/web/.env.local
# Add Worker/runtime variables when you need preview mode, agent admin flows,
# or parity with Cloudflare bindings
$EDITOR apps/web/.dev.vars
# Required beyond the example file:
# NEXT_PUBLIC_WALLETCONNECT_PROJECT_ID
#
# The example file already includes:
# NEXT_PUBLIC_POLY_BUILDER_CODE
# NEXT_PUBLIC_POLYMARKET_HOST
# NEXT_PUBLIC_POLYMARKET_WS_HOST
# NEXT_PUBLIC_POLYMARKET_CHAIN_ID
# POLY_RELAYER_API_KEY
# POLY_RELAYER_API_KEY_ADDRESS
#
# Common optional vars for local parity:
# NEXT_PUBLIC_APP_URL, NEXT_PUBLIC_POSTHOG_PROJECT_TOKEN,
# NEXT_PUBLIC_POSTHOG_HOST, POSTHOG_PROJECT_API_KEY, POSTHOG_HOST,
# OPENROUTER_API_KEY, EXTENSION_SESSION_SECRET,
# BUILDER_SIGNING_SERVER_URL, INTERNAL_AUTH_TOKEN,
# ALCHEMY_API_KEY, POLYGON_RPC_URL, COINMARKET_API_KEY

# Run the web app
pnpm dev:web

Open http://localhost:8000

pnpm dev:web reads apps/web/.env.local. pnpm preview and the Cloudflare Worker runtime read apps/web/.dev.vars, which is also where local D1/agent cron settings belong.

Extension Development

# Configure the extension environment
cp apps/extension/.env.example apps/extension/.env

# Optional overrides:
# DEV_MODE=false        # point the built extension at production
# POLY_BUILDER_CODE=... # builder attribution code for extension orders
# WALLETCONNECT_PROJECT_ID=... # required for WalletConnect/mobile wallet QR flows

# Run the web app locally for extension API calls
pnpm dev:web

# In a second terminal, run the extension build in watch mode
pnpm dev:ext

In development, the extension targets http://localhost:8000 by default. Use DEV_MODE=false in apps/extension/.env if you want the built extension to talk to production instead.

Scripts

Root workspace scripts:

pnpm dev:web        # Run the Next.js web app on port 8000
pnpm dev:ext        # Run the extension build in watch mode
pnpm build          # Build all workspace packages
pnpm build:web      # Build the web app only
pnpm build:ext      # Build the extension only
pnpm build:ext:dev  # Build the extension once in development mode
pnpm test           # Run workspace tests where defined
pnpm preview        # Preview the Cloudflare web deployment locally
pnpm lint           # Lint the monorepo
pnpm lint:web       # Lint the web app only
pnpm lint:ext       # Lint the extension only
pnpm format         # Format the monorepo
pnpm typecheck      # Type-check all workspace packages
pnpm typecheck:web  # Type-check the web app only
pnpm typecheck:ext  # Type-check the extension only
pnpm audit:security # Run a high-severity dependency audit
pnpm brand:render   # Render the brand mark asset
pnpm deploy         # Deploy the web app to Cloudflare
pnpm prepare        # Install Husky hooks

Package-level scripts live in the workspace packages:

• apps/web/package.json: dev:turbo, start, soak, soak:assert, cf-typegen, agent:d1:list:local, agent:d1:adopt-runtime-schema:local, agent:d1:adopt-runtime-schema:remote, agent:d1:migrate:local, agent:d1:migrate:remote, test, test:node, test:watch, test:coverage, test:e2e
• apps/extension/package.json: clean, test, test:scoring, benchmark:embeddings, format, version:bump, zip, release
• apps/agent/package.json: build, typecheck, lint, format, test

Common test commands:

pnpm --filter @knoww/web test           # Web Vitest suite + node-based tests
pnpm --filter @knoww/web test:watch     # Web Vitest watch mode
pnpm --filter @knoww/web test:coverage  # Web coverage run
pnpm --filter @knoww/web test:e2e       # Web Playwright smoke test
pnpm --filter @knoww/extension test     # Extension scoring tests
pnpm --filter @knoww/agent test         # Agent node tests
