Build a dapp on Chia

端到端教程：搭建一个 React 应用，用 dig-sdk 接入页内 Chia 钱包（window.chia + WalletConnect 回退），通过 chip35 wasm 构建并签名一笔支出，然后上链部署并添加自定义域名 —— 一条贯穿每个 DIG 基础原语的完整线索。

Building spends

Every on-chain action is built by the canonical CHIP-0035 wasm, signed by the user's wallet, and broadcast — the build → sign → broadcast split. Never hand-roll a spend bundle.

Changelog

What changed across the DIG developer surfaces — the digstore CLI, the dig RPC, and the window.chia provider — including breaking changes and the versioning rules for each.

Concepts & glossary

DIG Network 核心实体的单页索引 —— capsule、store、generation、URN、retrieval key、dig RPC、chia:// 协议以及链上锚定 —— 每个术语只定义一次，并链接到其详细文档。

Example gallery

Example DIG dapps you can clone and open in a template — a static site, a wallet-wired React app, and an NFT drop page. Start from working code instead of a blank folder.

For integration developers

一个完全机器可读的平台 —— OpenAPI/OpenRPC、一套完整分类的错误体系、实时定价、JWKS、逐页 JSON，以及一个类型化的 @dignetwork/dig-sdk —— 让你无需抓取一行人类阅读的文字说明，就能将钱包与已验证的读取能力接入你的应用。

How do I… integrate DIG into my app?

The shortest path for integrating developers: connect a wallet, read verified content, build a spend the right way, and deploy from CI — using the typed @dignetwork/dig-sdk and the dig RPC, no prose-scraping required.

Scaffold an app (create-dig-app)

npm create dig-app — scaffold a wallet-wired, deployable DIG app in one command. Five templates (static, vite-react, next-static, nft-drop, dapp-window-chia), all free to build and preview; you pay the uniform capsule price only when you publish.

Status

Where to check the health of the DIG services — the dig RPC (rpc.dig.net), DIGHUb (hub.dig.net), and the resolver (on.dig.net) — plus how RPC and provider versions are signalled.

The DIG SDK

@dignetwork/dig-sdk — ChiaProvider (injected window.chia + WalletConnect→Sage), DigClient (verified reads), Paywall (pay-to-unlock / NFT-gating), and the canonical CHIP-0035 spends at the /spend subpath.

The window.chia provider (specification)

Normative, versioned specification of the window.chia Chia wallet provider — the provider object shape, the EIP-1193-style request contract, every CHIP-0002 method with params/returns/error codes, the connect/202-pending contract, capability discovery, and EIP-6963-style multi-provider discovery.
