ABOUT Arium1.0

・Arium 1.0 is a service that allows you to create a free e-commerce website for selling Japanese products to other countries.Anyone can easily create their own customized e-commerce website without any previous web-design experience, using our intuitive and user-friendly interface.
・Anyone with something to sell simply enters their product information in their native language, and Arium performs all the translation necessary to effectively sell the product to any country in the world.
・When a purchase is made, sellers simply send their product to the Arium warehouse located domestically in Japan, and Arium will handle the entire international shipping process.
・When a purchase is made, Arium charges just 10% commission on the sales price. This is much less than rival platforms like, allowing sellers to list the products for a lower price, which in turn makes the Arium platform more attractive to buyers as well.
・We are running a crowdfunding campaign to evolve Arium 1.0 to Arium 2.0 - a decentralized, autonoumous, and free e-commerce app for the Ethereum network.



We started this project to solve four main problems.

  • Website Translation Cost and Accuracy

    International e-commerce requires translating your product descriptions, etc. into foreign languages. It usually requires huge startup costs. Automatic machine translation lowers costs, but the accuracy drops markedly. arium provides a new style which combines the low cost of machine translation with the accuracy of human translation.

  • Lack of Transparency in the Delivery Process

    Currently there is no comprehensive worldwide distribution system. Many distribution services have their own proprietary management systems, and the delivery status is not necessarily kept up-to-date. Packages can even get lost completely. arium solves this by managing delivery status on a blockchain.

  • Delivery Quality Assurance

    Currently there are many different supply chains intersecting across the world. Package-handling standards vary wildly, and when there is package damage it is difficult to determine who is responsible. The arium network introduces a system for users to evaluate the supply chain, which acts as a deterrent to careless package handling.

  • High Advertising Costs

    Traditional advertising involves the payment of a listing fee as an up-front investment, and the risk of poor cost-performance. The arium network takes advantage of an affiliate system to provide a new advertising system which charges only when you make a successful sale.

Benefits of the arium network

  • Cuts out the middle man by paying commisions automatically using smart contracts

arium Smart Contracts

arium2.0 utilizes 14 different smart contracts across 4 major categories:

Smart contracts which issue tokens

We are developing a smart contract for arium 2.0 which issues tokens called 'XRM' under the ERC-223 standard. ERC-223 is an interoperability standard for tokens on the Ethereum network which allows different tokens to be exchanged. It is an upgrade of the ERC-20 standard which addresses a critical bug in that standard.

Smart contracts which run the online marketplace

When a seller lists a product and uploads photos, price information, etc to the arium2.0 website, buyers can then buy the products with XRM tokens. We are developing smart contracts which enable these product listings and purchases. In addition, we are also developing a smart contract to manage and track payment information.

Smart contracts which manage and track delivery

Unlike traditional e-commerce, purchases on the arium network are paid for only upon delivery. When a product is bought on the arium network, a delivery company is contacted, who scans the product's proprietary QR code. A smart contract manages and tracks this delivery status information. Even when several delivery companies are involoved, each company will use a smartphone app to scan the QR code and create a chain of custody which is recorded on the Ethereum blockchain. When the final QR code is scanned, the completion contract notifies the payment contract, and payment is automatically performed.

The translation contract manages each product's translation information

The translators translate the product listing information on arium 2.0. The translation contract manages each product's translation information. Users rate the quality of each translation and this rating is also recorded.

ID Contract Category Contract Name Contract Function
1 Token Standard Token Contract Manages ERC223 Token and BasicToken distribution.
2 Token ERC223 Token Contract Manages ERC223 Token distribution.
3 Token Basic Token Contract Manages ERC223 Token distribution and fundamental token information.
4 Token ERC223 Basic Contract A contract that is made in accordance with Ethereum standard specification ERC20 and ERC223.
5 Token Exhibition Contract Manages product listing information such as price, size, weight, photos, etc.
6 Market Purchase Contract Manages product purchases. Notifies the seller when a purchase is made.
7 Market Settlement Contract Receives payments from buyers. Notifies the Payment Settlement contract.
8 Market Payment Contract Manages payment settlement. Checks whether the payment has been received and whether shipment has been successfully completed.
9 Delivery Shipment Contract Manages shipment. Notifies a seller when a purchase order is received.
10 Flow Contract Shipment Contract Manages the shipment tracking information which was uploaded by scanning the QR codes.
11 Delivery Complete Contract Records delivery completion. The payment settlement contract will not be activated until delivery is completed.
12 Interpreter Language Contract Identifies languages and manages translation data in order to spread products on the arium platform to many countries around the world.
13 Interpreter Rating Contract Manages translator evaluation data. Rates translators according to translation quality.
