  • DeFi Development

    We develop secure decentralized crypto exchanges. And integrate existing solutions, e.g., create pools for Uniswap, Curve, Balancer, Aave, etc., integrate Chainlink oracles, and integrate with bridges like Wormhole.

  • Building Development Processes

    We ensure that the code quality standards and documentation details are met. We also ensure that the linter and automated tests are properly included in the CI/CD pipeline and that they run simply, smoothly, and consistently.

  • Automatic Testing

    Automatic testing is the best way to ensure the product meets all requirements. So unit testing, integration testing, and other kinds of testing accompany our development throughout any project's life and allow us to improve the product in the most efficient ways constantly.

Processes We Build and Risks We Prevent

Any blockchain technology requires to follow principles that ensure open, transparent, and secure. It is essential when blockchain technology is used as a financial instrument and carries great financial responsibility. 

That's why we pay great attention to every process, such as processes synchronization of the development and testing team, strict planning and detailed specs writing, and different testing types at every stage of development. 

We've carefully collected the best practices of all processes in our Process Ebook, which you can download here. Enjoy your reading!

Building a unique NFT marketplace from stratch

Building a Unique NFT Marketplace from Scratch

The popularity of digital marketplaces for various types of products is increasing daily. NFTs are becoming popular outside of the crypto sphere, meaning NFT marketplaces are evolving as well.Marketplaces are where the general public can interact with content creators and are the entities responsible for facilitating NFT trading. Now, every content creator can become a prominent market seller just by participating in NFT marketplaces. As a new industry, there’s plenty of space for new ideas and niches. Thinking about creating your own NFT marketplace? In this article, we’ll discuss the various steps and costs involved.Non-fungible token (NFT) marketplaces are Web3 applications that allow people to buy and sell various types of NFTs. Some marketplaces are open to the public, such as those that allow people with crypto wallets to buy and sell their own NFTs. Others are not open to the public and only allow certain companies and brands to sell their NFTs.With an NFT marketplace, people can easily create accounts and sell their digital artworks and other items. Niche marketplaces are usually more in demand than standard ones due to their specialized features and ability to sell various types of art.The users of an NFT marketplace must first install a digital wallet to operate. This app stores the data of the owner's files on the blockchain, which is different from the data stored on a disk drive. In addition, it allows users to create collections by displaying the work or digital item they want to buy. They can then choose the payment token they want to accept.After the item has been listed, the transaction will be created following the auction. The creator's wallet then launches a smart contract to spell out the terms of the deal between the buyer and the seller. The blockchain network automatically generates and validates this deal.The transaction is then irreversible, as various operational costs are involved in a digital transaction. For instance, the energy costs associated with brokering a transaction, the gas fee, are usually included in the cost of an NFT. As a result, marketplaces use NFTs to charge a fee whenever funds are transferred.
