Overview
Varmeta is a software development company that builds blockchain, AI and AR/VR (augmented and virtual reality) products for other businesses1. Clients can hire it to run a whole project from planning to delivery, or bring in a dedicated team of engineers that works as an extension of their own staff2.
Varmeta was founded in May 2022 by three high-school friends and is led by founder and CEO Nha Tran3. Its head office is in Hanoi, Vietnam, with a second office in Da Nang4. On Cardano, Varmeta built a buy-and-sell feature for the Yoroi wallet, which is developed by EMURGO, one of Cardano's founding organizations5. In 2023 Varmeta developed a toolkit (an SDK) that connects the Unreal game engine to the Aptos network, followed by projects on Sui and Nibiru3. Its case studies also include a DAO toolkit on Hedera6 and a meme coin prediction app on Solana7.
Key Features
- Buying and selling crypto inside a wallet. For Yoroi, Varmeta connected Banxa, a service that converts regular money into crypto and back, so Yoroi users could buy and sell without leaving the wallet5.
- Sending Cardano tokens from a chat app. Varmeta's own research team built Adabot to let people send Cardano tokens inside Telegram, with multi-signature approval (more than one key must sign a transfer) and support for several wallets8.
- A Cardano toolkit for apps and AI assistants. The open-source Cardano Agent Kit is a TypeScript code library that handles wallet creation, sending ADA, staking to a pool and minting tokens, and it plugs into AI frameworks such as Vercel AI and LangChain so a chatbot can carry out wallet and token actions on request9.
- Starter code for tokens with editable details. A public Varmeta repository holds Aiken smart contracts (programs that run on the blockchain) for minting tokens under CIP-68, a Cardano standard that keeps a token's details in a record that can be updated10.
What to Expect
Businesses visiting the Varmeta site find service pages for blockchain, AI and AR/VR work, plus a portfolio of case studies. Case studies such as the Yoroi and Adabot pages name the client, country, build time and scope of work5,8. The Yoroi project, for example, lists two months of front-end development, the Banxa integration and unit testing (automated checks on each piece of code)5. A contact form books a call with the team, and the site lists separate phone lines for sales and careers4.
Developers can browse Varmeta's public code on GitHub. The Cardano Agent Kit installs as an npm package, a standard way to add code libraries to JavaScript projects, and works with Cardano data providers such as Blockfrost, Koios and Maestro9.
Cardano is one part of a wider portfolio, and the blockchain service list covers mobile wallets, DAOs (groups run by shared voting rules), exchanges, games and NFT marketplaces2. Varmeta's blog also has a guide to layer 2 options on Cardano, extra networks that run on top of Cardano to handle more activity.
