Mobilum Platform is a scalable ecosystem of building blocks — microservices, utilizing common open-source API and underlying protocol — a blockchain solution — to provide instant any to any conversion with best execution rates, fueled by the mobilum token (MBM).

Nowadays user experience is the main pillar of all customer-oriented applications. In order to provide the best experience and best practices to utilize the Mobilum Platform, XCARD project was created. XCARD utilizes Mobilum Platform API in order to provide state-of-the-art multicurrency wallet implementation and the first crypto credit card available.

Mobilum Platform consists of three main domains as of today:

Mobilum Platform ecosystem explained

XCARD — XCARD is an all-in-one digital wallet & the most convenient crypto credit card. You can perform any financial and cryptocurrency transactions in real-time, with no limits. Mobilum internalizer — A high frequency, low latency, multi-market, and multi-asset matching engine, which internalizes all customer's orders in real-time. It consists of Virtual Order Book and Pricing Engine, which provides Best Execution mechanism for traded assets, leverages Mobilum Liquidity Pools, and calculates Volatility Indexes of traded cryptocurrencies. Mobilum Foundation — Building blocks of Mobilum Platform done in microservices paradigm, utilizing open-source API, providing all services and interactions for the platform, including blockchains connectivity, banking system connectivity, payment processing, order management, security and many more.

There is one main rule in all domains of Mobilum Platform — an MBM Token is required as a membership token by invoking users to interact with and between the building blocks of the platform.

The amount of MBM Tokens is calculated as 0,5% of the transaction value by the Pricing Engine and exposed to all other building blocks through the API.

If the invoking user lacks the required amount and has an XCARD multi-sig wallet created inside the XCARD application, XCARD buys a missing amount of MBM Tokens on the user's behalf through the Internalizer using best execution rate. When the particular operation is invoked, a preliminary check by the smart contract is performed, to confirm that membership requirement is met. Otherwise, XCARD rejects the query.

Mobilum Foundation interacts with other systems through the APIs. One of the building blocks of the Mobilum Foundation is its blockchain solution, which stores all information about transactions performed on Mobilum Platform through the XCARD wallet application or open-source API. Access to the blockchain of the Mobilum Platform is possible through the open-source API or Mobilum Explorer — a web3 application. XCARD wallet utilizes the open-source API to show the full list of transactions of the given user in his wallet.
