Overview
Vtechcom is a software company in Vietnam that builds websites, mobile apps, and business management software for its clients1. Its blockchain team, Vtechcom Labs, makes developer tools for Hydra, an add-on to Cardano that processes transactions among a small group of participants, off the main chain2. The tools are aimed at teams building apps that need fast responses, such as games, payment services, and wallets3.
Vtechcom was founded in 2015 and started out making ERP software, the systems a company uses to run its operations in one place, along with websites and branding work4. In 2021 it began researching blockchain, the metaverse, and AI, with the aim of building decentralized finance products4. Its Cardano work is funded through Project Catalyst, Cardano's community-voted grant program, which lists the team's Hydra SDK developer toolkit, Hydra Hub, and Hydra Hexcore proposals as complete5.
Key Features
- A toolkit for building Cardano wallets and apps. The Hydra SDK, a set of ready-made code building blocks, lets developers create and restore wallets, build transactions, and connect apps to Hydra6. Vtechcom publishes the code under the open-source Apache-2.0 license7.
- Ready-to-use Hydra servers for testing. Hydra Hub is designed as a shared, low-cost service that hands developers working Hydra nodes, the servers that run the add-on, so they can test and launch apps without building their own setup8.
- Automated setup for multi-party Hydra groups. Hydra Hexcore is a backend service that creates and manages Hydra nodes, adds the parties who take part in a Hydra group, and processes transactions on the add-on9.
- Documentation that AI coding assistants can read. The Hydra SDK docs connect to AI coding tools through the Model Context Protocol, a standard way for assistants to fetch reference material, and come in English, Vietnamese, and Japanese3.
- Custom software for businesses. Outside blockchain, Vtechcom offers web and mobile development, interface design, software testing, and IT consulting, with past work including an ERP system for SEICO Group and a truck booking system10.
What to Expect
Developers get the most from the Hydra SDK site, which has an installation guide, code examples, and step-by-step tutorials for building wallets6. An online playground lets visitors try the SDK's features in the browser before installing anything6. The site also lists sample apps built with the toolkit, including a tournament game and a lottery game that uses NFTs as tickets6.
The source code lives on the company's GitHub organization, which also holds Hydra Hexcore and smaller experiments11. One of those, documented in Vietnamese, is a Hash Time Locked Contract written in Aiken, a language for writing programs that run on Cardano. The contract releases funds to whoever presents the right secret before a deadline, and refunds the sender after it12.
Businesses looking for an outsourcing partner will find a conventional IT services site at vtechcom.org, in English and Vietnamese1. It lists services, a portfolio made up mostly of website projects for Vietnamese companies, and a contact form for requesting a consultation1. Vtechcom describes a seven-step process that runs from gathering requirements through delivery, training, and ongoing maintenance10.
The Cardano work is easier to follow on the Hydra SDK site and GitHub than on the company homepage, which focuses on general IT services1.
