The Trade System allows players to trade Prime Blueprints, Prime Parts, Mods, 
Platinum, Void Keys, alternate Arcane Helmets, Kubrow Imprints, and Special Weapons at the Clan Dojo's Trading Post, or at a specified trading relay (Maroo's Bazaar). There is a minimum Mastery requirement of Rank 2 in order to trade, and the number of available trade transactions increases by one each Mastery Rank. Up to five items can be traded per transaction and a trade tax is commissioned to complete the trade. The Trading Post can be found in the Place Decoration tab if you are an Architect in your Clan.
Players can also trade on Earth at Maroo's Bazaar.
- Note* When trading weapons, weapon parts and Warframe parts, a player can only trade that weapon or frame if it is Prime, or has special status, like Prisma or Syndicate. The only current exception to the Prime Warframe rule is Nezha.
- Another Note* Only prime parts that drop as parts can be traded, prime parts that are crafted from blueprints cannot.
Trades Per Day
The Trading Post as it appears in-game.
The number of trades that can be made per day is the same as the player's Mastery Rank, with exception to Founders, who get an additional two trades per day. The trade limit is refreshed daily at GMT 00:00 and is not affected by the amount of items exchanged in each transaction. Furthermore, ranking up will provide an additional trade until the next refresh.
Tax
Trades are charged for a trade tax which amount in
Credits based on the rarity of the commodity. Players will need to pay the respective tax for the item they receive in the trade. Additionally, a Clan tax can be set by the Clan that the Clan Dojo is associated with.
Primed Mods such as Primed Flow are considered "Legendary Items", therefore costing a trade tax of 
1,000,000. However, Primed Mods obtained from Daily Tribute cannot be traded.

1) Special Weapons must be unused, without any Affinity, Forma or Orokin Catalysts to be tradeable. 2) Players cannot trade the initial amount of platinum that all accounts start off with. This is to prevent players from creating new accounts to farm platinum. Players cannot trade platinum that has been gifted to them as well. 3) Nezha is currently the only non-prime Warframe whose parts can be traded, and uses the same tax per part.
