Machine to Machine and Machine to Business Payments Platform
Challenge
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.
Solution
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.

The Notary Platform: Engage in contract on the go.
Goal
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.
Solution
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
Features
- Support 20+ crypto wallets via wallet connect
- Internationalisation
- Transaction history
- Transaction tracking
- Admin portal
- Monitoring & Alerts
Technologies
Solidity, Ethereum, Golang, Ngnix, React Native, Uport, PostgreSQL
About Client
The Notary Platform is a blockchain startup based in Slovenia, revolutionising the way we engage in contracts.

Swap.Global: Algorithmic ERC20 Token Swap Platform
Challenge
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.
Solution
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.
Features
- Support 20+ crypto wallets via wallet connect
- Internationalisation
- Transaction history
- Transaction tracking
- Admin portal
- Monitoring & Alerts
Technologies

Meritt: Lending Platform
Challenge
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.
Solution
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.
Technologies
Solidity, Ethereum, Truffle, Vue JS
About Client
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.
