As a blockchain consulting company, the main goal of our team is to create technology that will help our clients reach new heights. Our software consultants and developers are dedicated to understand their needs and to offer personalized solutions.

Тhe team behind WeiChain has a rich history in blockchain space. We’ve worked together with the teams behind some of the most successful projects in the crypto world — Aave, Ava Labs, MakerDAO, Algorand Foundation, etc. We’ve played around with leading blockchains and have contributed to the further improvement of their own ecosystems. During the years our team has created multiple DApps and tools, that make our portfolio extremely rich.

Here is a small part of things we’ve built and chains we’ve worked on:

👉 Ethereum

Ethereum is the leading blockchain network out there enabling the development of thousands of applications with different purposes. It’s a community-built technology that is open to everyone. It gives access to powerful resources, tools and repositories and gives space for further contributions. It is the network behind the cryptocurrency Ether (ETH) and hundreds of other tokens. Last but not least, it is the basic layer of the DeFi industry.

Ethereum was our starting point back in 2017 and up until now we’ve acquired great experience with this profound technology. We’ve built all kinds of solutions — DeFi applications, NFT tokens, Uniswap forks, Private Enterprise Networks, and several L2 solutions. We’ve built a product based on HTLCs (Hash Time Locked Contracts) that became a fully functioning cross-chain bridge between Ethereum and other chains. These efforts led to the first fully decentralized value transfers of native tokens between heterogeneous networks. You can learn more at <https://jelly.market/>

WeiChain audited

The next thing that these years of experience have naturally led us to are the security audits. Producing a quality piece of code is not enough. This code should be carefully audited and validated as secure. Most of the products in the blockchain space are still focused on financial purposes and are aggregating great value of money. Thus, security should be our first priority. A careful audit may find crucial weaknesses in the source code, remove them and suggest improvements towards perfection.

👉 Bitcoin

Although its main purpose is the store of value and peer-to-peer transactions, and it does not offer the vast opportunities of Ethereum for building layers and products on top of it, Bitcoin remains one of the most important blockchains out there. Exchanging value between different networks in a trustless way is not an easy task. Up until this point, HTLCs proved to be the most secure way of solving this interoperability issue. So, we used them to create a cross-chain bridge between Bitcoin and other networks and to respectively help people exchange BTC<>ETH in a few steps while keeping the custody of their assets.

👉 Binance Smart Chain

Binance is one of the most progressive projects in the space. They successfully foresee every trend and need of the market and manage to offer the appropriate solution. We had the pleasure to work with their technology stack in order to create smart contracts with different DeFi and interoperability use cases. Once again, we contributed by building a cross-chain bridge that connects BNB to other currencies. Binance Chain is EVM-compatible which made things simple and familiar to us.

👉 Near

The whole concept of Near is focused on decentralized applications. This network provides one of the easiest ways to build your own application on top of it. It claims to be not only developer-friendly but also performant and secure enough to manage high value assets like money or identity. What we were requested to build on NEAR Protocol by one of our clients was an SDK for cross-chain bridge based on chain abstraction layer. One of the main advantages of the network is its scalability — the Near platform may scale nearly linearly up to billions of transactions in a fully decentralized way. <https://github.com/liquality/chainabstractionlayer>

👉 Avalanche, Harmony, Matic, Tron

The one thing that unites all of them is that they are all EVM-compatible. Each of these chains has its own purpose and has contributed to the evolution of the blockchain space. What we did for all of them was to create the cross-chain bridge they needed for secure and trustless value exchange between their native tokens and main cryptocurrencies such as BTC and ETH.

👉 Algorand

It is a network with great technical progress. They’ve managed to launch a mainnet with the amazing capability of handling 1,000 transactions per second with a latency of fewer than 5 seconds. What they are trying to solve is the so-called Blockchain Trilemma without sacrificing any of the three pillars — decentralization, scalability, security. Our team joined the process to build a cross-chain bridge in order to make it easier for ALGO token holders to quickly and seamlessly exchange ALGO for other tokens and coins in a fully decentralized way.

👉 Aeternity

Having corrected the fundamental scalability flaws in earlier blockchains, the Aeternity protocol is engineered to accommodate large-scale enterprise use cases. Aeternity enables the tokenization of both virtual and real-world assets such as fungible and non-fungible tokens. It is one of the first chains we’ve worked on and we’ve built a lot on it. Apart from the cross-chain bridge, we’ve also built a fully functioning DEX as long as their first stable coin (AES).

🥇 Why choosing us

This diversity of blockchains, use cases, projects and requirements have helped our developers gain the experience they need in order to recognize what is the best solution for each client. We listen carefully to what you want to achieve and go through a deep research before kicking-off the development process. We stay with you even after the delivery — for any kind of technical support and maintenance. Let us build your product and keep it safe!
