XDEX Markets is a post-trade market settlement automation module that integrates directly with third-party exchanges and alternative trading system platforms to help asset owners, offering sponsors, and sell-side intermediaries to capture and aggregate external trade data and to ensure governance and compliance of post-trade market settlement processes.

When a 3rd-party market-listed asset is matched for a trade by the trading venue, XDEX Markets provides an automated notification messaging framework to connect between asset issuers and third-party custodians. When order match notification is received from an external trading venue, XDEX Markets automates the process of connecting buy-side and sell-side custodian accounts, thus facilitating compliance workflow processes to settle the trade and transfer of the assets.

XDEX Markets can handle the trading volume of the NASDAQ, while settling orders within a few seconds after submitting the transaction request.

With XDEX Markets, governance and management functions are separated from trading and exchange. This allows the application to segregate users of a common asset class into different roles.

Since XDEX record-keeping is global, and can operate autonomously outside of any centralized entity to decentralize the world’s liquidity to a decentralized, global order book for market trading.

XDEX is asset agnostic. Users can trade at any pair. While some pairs may end up with low liquidity, others will see huge volume based on the global user interest in specific asset tokens.

Funds and trade ledger data at the protocol level are secured with industry-grade elliptic curve cryptography. No one can access a an Authorized User’s funds or assets unless they are granted permission, which is logged to the network. To further strengthen the security the XDEX Markets wallet system enables Authorized Users to setup escrow and complex multi-signature schemes mirroring any corporate or organization legal structure.

XDEX Trading Engine

XDEX Markets also powers a decentralized, protocol-based Trading Engine marketplace function built on top of the consensus and operations layer of the XDEX Network blockchain. It is a native, protocol-level application feature that does not rely on user defined code execution, as all functionality is built into the protocol node software itself.

The XDEX Trading Engine permits Authorized Users to create limit orders to trade different digital assets on the XDEX Network blockchain. When an Authorized User creates a trade, it is placed on a market. The market tracks all open and filled orders for a certain trading pair and tracks the last price and 24h volume. XDEX Trading Engine supports an arbitrary number of markets (as well as assets). Any order is matched within the engine logic by the criteria of best price and time of creation once a fitting order is created. The orders can be partially filled, with the remainder remaining in an open position. A user also has the option to create a fill-or-kill order that must be matched on creation. Authorized Users may also cancel open orders at any time.

The XDEX Trading Engine order book is enabled by user signed operations that create and cancel limit orders. The user must properly sign a valid create limit order operation in order to create a limit order. The operation is considered valid if the user has enough verified funds to create the order. Once the operation is executed, the XDEX Trading Engine will attempt to match the order. This is NOT tied to block creation or the consensus mechanism of confirming transactions. The XDEX Trading Engine will proceed to search all limit orders for a given market pair sorted by price ratio and time of creation. If a match is made, and the order is fully filled, the XDEX Trading Engine will exchange the assets between trading accounts, swapping the appropriate amounts of tokens to complete the trade.

If the order is partially matched, or if it is not matched, a unique order object is created on the global share state, and the authorized user is notified of its id. This unique order object contains the information about the amount and type of tokens to sell, as well as the minimal amount to receive. The values are equal to the original values input by the user in the create limit order operation if the order was not filled, or they are adjusted to match the partial filling of the order if a match has happened, but the order was not fully filled. This object persists in the state until it is either filled entirely by another created limit order or cancelled by the authorized user. The user may cancel an open limit order by properly signing a valid cancel limit order operation. The operation is valid if it contains an id of an existing limit order object and is signed by the creator of the object (and the limit order itself).

An important thing to note is that trades are executed immediately, regardless of confirmation. To achieve additional confidence, the user may wish to wait for a confirmed limit order to appear, meaning only such order that was confirmed in a block, and then trade in accordance with the confirmed order.

Depending on the jurisdiction, asset class, and token, there are potential regulatory issues that require XDEX extended business rule engine to ensure the regulatory compliance of a particular trade operation and venue between Authorized Users.

For example, securities are only legally tradable on a licensed securities exchange. In this case, the entire XDEX Trading Engine and tokens constituting securities would only be activated for active order trading through a licensed securities exchange or broker dealer operating as an ATS (Alternative Trading System) with regulatory approval.
