2018
Back in 2016, our team worked side by side with the Qtum team to help the company launch its own scalable open-source Qtum blockchain platform. Distributed Hub helped the team to develop a Decentralized Governance Protocol (DGP), allowing for blockchain parameter customization, and engaged in the implementation of a block explorer, a PoS consensus on the Bitcoin fork, along with integration with Ethereum and WASM virtual machines. The results of this collaboration effort are described in detail here.
Qtum Foundation Ltd., a Singapore-based corporation specializing in mobile decentralized apps (DApps), launched its platform in September 2017. With a market cap of $4B, Qtum is one of the 40 most popular digital currencies as of January 2020.
To date, there are nearly 6,000 Qtum nodes operational around the world, most of which are located in the US and run on AWS and Google Cloud. With over 200 launched DApps, the Qtum project is backed by some of the most notable blockchain players and executives from well-known global tech companies.
Having recently introduced upgrades with EVM and launched the first x86 VM smart contract on the mainnet, Qtum Foundation turned to Distributed Hub for custom mobile crypto wallet development. They needed a convenient cryptocurrency wallet interface with additional features for offline stacking, communication with the blockchain, and diving into every perk of the Qtum platform.
Our team was responsible for:
Building iOS and Android multi-currency crypto wallet specifically for the Qtum blockchain;
Achieving a smooth and fast connection to the Qtum network;
Securing the app and user transactions from hacker attacks, malware, phishing, and unauthorized remote access.
Ensuring Exchange Liquidity & Profitability
The result we delivered was the Qtum mobile cryptocurrency wallet, an easy-to-use yet powerful tool for tamper-proof direct transactions, powered by end-to-end encryption mechanism. We introduced the support of ERC20 tokens and management of several accounts to facilitate sending, receiving, and storing of all the user’s coins in one app.
The cryptocurrency wallet encodes private keys and all transaction data right on the mobile device. We implemented a client-side encryption feature to make the user account and all transactions private before this information touches a third-party server.
In-App Smart Contract Builder
Distributed Hub team also delivered a user-friendly smart contract builder to help easily draft smart contracts with the help of ready-made templates right from your mobile device, using just the Qtum wallet. The tool enables the users to even create their own templates, which is very helpful when you need to use smart contracts for different purposes on a daily basis.
In the end, we produced two separate implementations of the Qtum cryptocurrency wallet for iOS and Android.
