Our goal was to launch a primary marketplace for trading of the Global Stability Unit, GSU, to and from fiat currencies. Where the trading of other digital units such as BTC (Bitcoin) and ETH (Ethereum) would be also possible. Solutions available in the market lack the operational perspective in terms of essential administrative and security controls required to operate a high volume marketplace.

GSU Exchange is a secure, scalable and ultra low latency cryptocurrency trading platform to match with high volatility of the crypto industry. It offers easy to use flows; deposits and withdrawals of currencies and cryptos, trading and transactions – all accompanied by a full account and transaction overview. Exchange is developed by using distributed and fault tolerant technologies making it highly flexible and reliable. It’s Matching engine can work with any type of assets. Enterprise grade protocols are used for identity and access management which provides easy integration across the organisation. Provides risk management with real-time error checking and alerts. Builtin KYC portal supports integration for financial institutes which makes it compliant with digital security laws. Zendesk support system is used for higher customer satisfaction.

Integrated Blockchain Technology (IBTech.io) is the primary business that commercializes the distribution and use of the world’s most stable unit, the GSU. It is based in Denmark and focused on end-user applications based on blockchain technology.

Our goal was to develop a platform that provides secure wallets to smart devices so they can make transactions as per defined rules (Smart Contracts). So business can increase efficiency and reduce operational cost by enabling faster and automatic transactions as license agreements.

By leveraging the power of Blockchain technology we created a blockchain enabled IoT gateway that allows devices to securely communicate and transact value with each other through a shared ledger. Bi-directional distributed infrastructure allows devices to securely communicate with smart contracts and synchronise their balances. A dashboard was created for on boarding, usage monitoring, wallet recharge and device control purposes. We created an interactive interface for configuration of smart contracts with payments rules and other service conditions.

• Identity & Access control
• Automated rules based Payments
• Real-time usage Monitoring
• Security and trust through design
• Availability
• Interoperability

Our goal was to provide an easy way to swap GSU with ETH and other ERC20 tokens like USDT, without the need of login or KYC. Smart contracts based decentralised token swap is easier if it is peer to peer and doesn't require integration with any external system. But in our case, both were there, GSU is an algorithmic currency so each swap requires real time communication with the rate system and it wasn't peer to peer which introduces liquidity challenges.

We created a DApp with easy user experience that allows users to swap GSU with ETH or USDT at current rates. For rate system integration, a distributed middleware was designed to avoid single point of failure or compromise. To ensure the availability of liquidity, a smart contract monitoring system was designed to trigger alerts when liquidity is below a certain threshold.

A product of GSU (GSU.io) - The GSU (Global Stability Unit) or simply; 'the Global' is a market-based crypto token that beats currency in stability and efficiency.

Micro and small loans are underserved and usurious which results in a $2 trillion financing gap. Lenders are out of reach and expensive. They are also blind to alternative datasets resulting in missed opportunities for investors and for creditworthy individuals and businesses. So Meritt goals was to build a lending platform that tokenizes loans to diversify the risk for lenders.

We created a DApp that list lending opportunities. It issues loan tokens lenders that represents interest rate, repayment schedules and principal amount. Lenders can further trade these loan tokens. Credit worthiness of borrower starts from a very small loan and increase with repayments history.

Meritt is a fintech startup based in London building a direct lending platform that enable individuals & businesses to harness their everyday data to access instant finance.

Contracts are an integral part of business and everyday life. The current labour intensive process of creating, signing, and storing contracts is an expensive way to create agreements between different parties. So Notary aimed to tackle this using cutting edge blockchain technology to create an efficient method of creating, storing and signing contracts - anywhere and anytime.

A mobile application built on Ethereum blockchain network that offers the use of templates for standard contracts for different real-life cases in an intuitive and user-friendly interface. Blockchain technology provides the proof of the digital documents’ existence, content and identity of involved parties by allowing the creation of a timestamp and storage of digital documents in a form that prevents tampering with them. Applications also allow users to combine different digital sources into their final contract to provide for additional information. These sources can be used individually or in combination and include:

• Templates or written and then scanned forms,
• Sound files
• Image files
• Video files
• Proof of existence (e.g. facial recognition, retinal scans, etc.)
• Different digital files or just the hash of a digital file in case of confidential data

• Support 20+ crypto wallets via wallet connect
• Internationalisation
• Transaction history
• Transaction tracking
• Admin portal
• Monitoring & Alerts

The Notary Platform is a blockchain startup based in Slovenia, revolutionising the way we engage in contracts.

Performed Crowdsale Smart Contract Audit, No critical issues have been found in the code. Medium and low severity issues have been identified and respective corrections have been proposed.

Our goal was to develop a blockchain network with smart contract (programmable) based fee mechanism so each application can implement their own fee model, without compromising on security and transaction speed.

Because of it's permissioned and enterprise nature we chose Quorum blockchain as our starting point. We added a layer on top to provide a programmable fee mechanism and replaced it's iBFT with HiBFT to address trust and security issues between parties at different authority levels.

• Ethereum compatible
• Secure and fast
• Byzantine fault tolerant
• Fixed transaction fee
• Blockchain explorer
