ShardSpace has partnered with AlphaDex to provide Limit Order functionality directly from your ShardSpace workspace.

What is AlphaDEX?

AlphaDEX is a scalable and efficient decentralized order book exchange platform on the Radix network. It provides a central order book and matching engine that can be seamlessly integrated into a wide variety of applications, whether it is a simple swap widget or a sophisticated trading platform.

Why use an order book exchange?

  • There are already many AMM exchanges available on Radix

  • Can specify (and guarantee) the exact price you want to trade at

  • No front-running possible

  • No impermanent loss (liquidity provision still has some risks)

  • More efficient liquidity provision than AMM (less liquidity required for same slippage)

  • Better supply and demand discovery by seeing full order book at different price levels

  • Users are already familiar with centralized order book exchanges (e.g. Binance, Coinbase etc.)

  • More suited for advanced trading strategies and risk management


There are three main fee types on AlphaDex The maximum fee of 0.5% paid by the person submitting a matched order (sometimes called the market taker) is distributed as follows:

  • Liquidity fee of up to 0.35%: This fee is paid to the liquidity provider (sometimes called the market maker). The liquidity provider is the person whose order was already on the exchange and which matched the order of the market taker. The liquidity fee for each pair will depend on the volume of trade in that pair. The higher the volume of trade, the lower the liquidity fee. The liquidity fee limits are from 0.35% to 0%.

  • Platform fee of up to 0.1%: This fee is paid to the platform/app through which the order was placed (e.g. the swap or exchange app through which the user placed the order). The platform owner can specify this fee for every order. ShardSpace charges a 0.1% platform fee.

  • Exchange fee of 0.05%: This is the fee for using the AlphaDEX exchange and will go towards the running and continued development of the exchange.

  • Any discounts in liquidity fees or platform fees are passed on to the user, resulting in a lower overall fee for the trade.
