Trade Structure & Functionality

An overview of the structure and functionality of a brokered trade.

Brokering a Trade

Brokering a trade is a tiered process that involves specifying the assets to be involved and the parameters of the trade.

Profile

On your Profile page you can view your assets, trades you have brokered, trades you have joined, and trades you are eligible to join.

Joining a Trade

You are eligible to join a trade if you possess the assets specified on one side of a trade that someone else has brokered. A brokered trade is executed once both parties have joined.

Canceling/Unjoining a Trade

If you have previously brokered or joined a trade, you may elect to cancel/unjoin the trade at any time before the second wallet joins.
