Overview

web3market-kit is a monorepo with 9 packages organized into four layers:

Layer 1: Shared Configuration

PackageDescription
@web3marketlabs/tsconfigShared TypeScript configuration

Layer 2: Core Libraries

PackageDescription
@web3marketlabs/sdkChain definitions, ABI utilities, Viem client factories, type exports
@web3marketlabs/configConfiguration loader and Zod schema for kit.config.ts
@web3marketlabs/codegenTypeScript binding and React hook generation from compiled contracts
@web3marketlabs/apiHono API server — authentication, templates, deployment preflight, AI endpoints

Layer 3: Feature Packages

PackageDescription
@web3marketlabs/componentsComponent registry (token) with Handlebars templates
@web3marketlabs/reactReact components (KitProvider, ConnectButton, TransactionButton)

Layer 4: CLI

PackageDescription
@web3marketlabs/cliCLI binary (w3m) — new, auth, add, dev, test, deploy, generate, templates, audit
@web3marketlabs/create-web3-dappnpx @web3marketlabs/create-web3-dapp — runs w3m new under the hood

What Works Without Authentication

All local development features work without authentication:

  • w3m new — Create projects from templates or interactively
  • w3m dev — Start Anvil + deploy + frontend dev server
  • w3m test — Run contract and TypeScript tests
  • w3m audit — Run Slither security analysis
  • w3m — Interactive workspace menu
  • Local deployment — Deploy to Anvil from the workspace menu

Authentication is only required for deploying to testnets and mainnets (w3m deploy --chain <chain>), browsing templates (w3m templates), and marketplace publishing (w3m publish).
