Borderlands 4 is all about looting, shooting, and sharing the chaotic world of Kairos with friends. Having a team of Vault Hunters coming together to take down hordes of enemies and acquire tons of loot is often better than running around the world by yourself. In typical Borderlands fashion, you are continuously showered with guns, shields, grenades, and class mods that often don't align with your build. However, in Borderlands 4, instead of letting them go to waste, you can easily trade them off with fellow co-op Vault Hunters.
In this guide, we will break down the workings of the trading system in the latest Borderlands title and explain how to utilize it effectively.
How to begin trading with friends

To start trading with your co-op friend, the first thing you need is to be in the same session. Then, stand near your co-op partner and aim your view directly at their Vault Hunter. A "trade" prompt will appear on screen, which means you can begin trading. You can then send them the trading request and wait for confirmation from their end.
The trading interface is simple and designed to avoid trade errors. Both trading parties can see what’s on the table before they confirm the trade, allowing for a fair experience.
For every trade, both players need to confirm their offered items before the deal can go through. This is important in order to eliminate any accidental giveaways that might lead to misunderstandings. Once the deal is confirmed, the items are immediately transferred between the two parties' inventories. This step is irreversible, so make sure you double-check what you are giving away.

What can you trade in Borderlands 4

The trading system in Borderlands 4 supports almost every kind of gear you can acquire during your adventure across Kairos. These include:
- Weapons - Everything from pistols to rocket launchers; any weapon in your backpack can be traded off.
- Shields - Having a better shield is always good for your build, and acquiring one from a fellow player is one of the easier ways to get them.
- Grenade Mods - Borderlands 4 offers a large variety of Grenade Mods, and you can trade for them with your co-op partners.
- Class Mods - These are one of the best things you can trade for with friends in the latest Borderlands title.
- Relics - Having excess relics that are of no use to you can be traded off with fellow Vault Hunters.
- Money - While Borderlands 4 offers a ton of money through main and side quests, you can still share money with your co-op partners if they are running low.
Since you can easily fill up your inventory simply by killing one boss, it's useful to trade often. If you are playing co-op, trading with friends is a great way to support them. As for solo players, it's best to just sell your items at a store to make some quick cash.

Minor tips and tricks for optimal trading:
- Have clear communication with whoever you are trading with in order to avoid trade errors.
- Items you trade with others don't downgrade to your level, so check item levels before trading, or you might have to wait before you can use them.
- Trade smartly. Remember that not every class benefits from every type of weapon in Borderlands 4.
Looted items fuel the primary economy of Vault Hunters, but since the drops are RNG-based, you might get gear that's beneficial for a different class. These items are best suited for trading with friends, to ensure they get used rather than clogging up your inventory. When you are running lengthy co-op sessions, having a solid trading setup can lead to a shared loot pool.

Rare and Legendary items drop rarely in Borderlands 4 from world events and bosses, and can be a lengthy grind. These valuable items are highly sought after by every Vault Hunter.
The overall simplified trading system is one of the best additions to Borderlands 4; whether you are just passing along a Legendary gear to your partner or acquiring one from them, the trade system ensures the proper distribution of loot in the game. So, the next time you are exploring and you come across a rare weapon that doesn't suit your class, do not sell it or throw it away. Help out a fellow Hunter in finishing their build instead, and you might just get something good in return.
