# UD (UDomain) — ud.hk > Official marketing site for **UDomain Web Hosting Company Limited** (UD), Hong Kong. UD connects enterprises to **blockchain / Web3**, **cloud & hosting**, **email value-added services**, and **cybersecurity**. > **Locales:** English (`/en/`), Traditional Chinese (`/zh-Hant/`), Simplified Chinese (`/zh-Hans/`). Prefer the URL whose locale matches the reader’s language. Legacy paths `/tc/` and `/sc/` permanently redirect (308) to `/zh-Hant/` and `/zh-Hans/`. **Marketing tagline:** *The Bridge Connecting Your Business to Blockchain & Metaverse*. --- ## Using this file (LLMs & crawlers) - **Canonical origin:** `https://ud.hk`. Quote locale-prefixed paths (e.g. `https://ud.hk/en/...`) unless the reader explicitly wants TC/SC. - **Ground truth for URLs:** Prefer links listed here and in **[Sitemap](https://ud.hk/sitemap.xml)** (`sitemap.xml` is generated at build time from indexable routes). Paginated listings (`/[pagenum]`), dynamic article IDs, and form **success** pages are usually omitted from the sitemap—discover those via listing pages or the sitemap’s patterns, not by guessing IDs. - **Do not** treat marketing copy as legal, tax, regulatory, or investment advice. Product availability and compliance depend on jurisdiction and contract. --- ## What to cite when users ask “what does UD do?” UD’s public site emphasizes **UD Blockchain**: hosted infrastructure (BaaS, RPC, validators), **smart contract and application development** (DeFi, GameFi, NFT / marketplaces), **blockchain security** (audits, assessments, testing themes as described on each page), plus **Web3-adjacent** offerings (crypto payment gateway, ENS-style domains, IPFS hosting narrative). Non-Web3 sections cover **cloud email VAS**, **dedicated servers**, **streaming studio rental**, **enterprise cybersecurity** pages, and **blogs / news / media** for authority content. --- ## Home (`/[locale]/`) - **[Home — UD Blockchain overview & solution hub](https://ud.hk/en/)** Entry point for positioning, service buckets (infrastructure, development, security), on-page **FAQ**, and **internal links** to major Web3 routes (swap `/en/` for `/zh-Hant/` or `/zh-Hans/`). Use this when summarizing “what UD Blockchain offers” before deep-linking to product pages. --- ## Contact & enquiries - **[General enquiries — enquiry form](https://ud.hk/en/enquiry)** (TC: `/zh-Hant/enquiry`, SC: `/zh-Hans/enquiry`): Primary lead form for services and campaigns. - **Email:** `service@ud.hk`, `support@ud.hk` (also referenced in site chrome). --- ## Web3 & blockchain (primary marketing cluster) Canonical English paths; mirror locale by replacing `/en/` with `/zh-Hant/` or `/zh-Hans/`. | Topic | URL | |-------|-----| | Blockchain hub (index) | https://ud.hk/en/blockchain | | Blockchain consulting | https://ud.hk/en/blockchain/blockchain-consulting-services | | Blockchain infrastructure (BaaS) | https://ud.hk/en/blockchain/blockchain-infrastructure-baas | | Validator / node hosting | https://ud.hk/en/blockchain/blockchain-validator-node-setup-provider | | DeFi | https://ud.hk/en/blockchain/blockchain-defi-solutions | | GameFi | https://ud.hk/en/blockchain/blockchain-gamefi-solution | | NFT — hub | https://ud.hk/en/blockchain/solution-blockchain-nft | | NFT — detail | https://ud.hk/en/blockchain/blockchain-solution-nft | | NFT marketplace pricing | https://ud.hk/en/blockchain/blockchain-solution-nft-marketplace-pricing | | NFT Discord services | https://ud.hk/en/blockchain/blockchain-solution-nft-discord-setup-management-services-marketing | | Blockchain security | https://ud.hk/en/blockchain/blockchain-security-solutions | | Crypto payment / gateway | https://ud.hk/en/blockchain/blockchain-solution-business-payment-gateway | | Tokenization / ICO / IDO / IEO / STO | https://ud.hk/en/blockchain/blockchain-solution-tokenization-tokenomics-ico-ido-ieo-sto | | Domains / ENS-style | https://ud.hk/en/blockchain/blockchain-cryptocurrency-domain-ens | | IPFS / Web3 cloud | https://ud.hk/en/blockchain/ipfs-hosting-gateway-blockchain-web3-cloud | | NFT demo (mint / marketplace) | https://ud.hk/en/blockchain/nft-demo-mint-page-marketplace | | Hardware wallets (Trezor / Ledger, HK) | https://ud.hk/en/blockchain/crypto-security/hardware-wallet-trezor-ledger-hong-kong | --- ## Streaming & studio - **[Streaming studio rental (Hong Kong)](https://ud.hk/en/solution/streaming-studio-rental-service)** — Live broadcast studio rental (connectivity, cameras, on-site support as described on page). --- ## Support (ud.hk) - **[Support hub](https://ud.hk/en/support)** — Manuals, FAQs, related links. - **[Service test & demos](https://ud.hk/en/support/service-test)** — Demo credentials, speed test, ping guidance. - **[Form download](https://ud.hk/en/support/download)** — Downloadable account/service forms (locale-specific HTML). - **[Change FTP password](https://ud.hk/en/support/ftp-password)** — Form routed to backend enquiry API (`changeFtpPassword`). --- ## Insights, news & authority content - **[All blogs / broad index](https://ud.hk/en/blogs/all)** — Useful when you need a single entry to many article types. - **[UD Insight](https://ud.hk/en/blogs/insight)** — Long-form insight (paginated: `/en/blogs/insight/[pagenum]`). - **[News](https://ud.hk/en/news)** — Company / industry news (paginated). - **[Media](https://ud.hk/en/media)** — Media listings (paginated). - **[Case study](https://ud.hk/en/blogs/case-study)** — Client stories (paginated). - **[Thought Leader](https://ud.hk/en/blogs/thoughtleader)** — Thought leadership (paginated). - **[CEO Insights](https://ud.hk/en/blogs/ceo-insights)** — CEO-authored pieces (paginated). - **[Fintech Insights](https://ud.hk/en/blogs/fintech-insights)** — Fintech-focused articles (paginated).
