How do you farm silverwastes?
Silverwastes is accessed through Fort Vandal in Brisban Wildlands.
You can buy keys with Bandit Crests. You get those by doing events in the Silverwastes, basically, though you can also get them from other sources (like Living World episodes, Piles of Silky Sand).
Chests aren’t “obtained”. They’re basically scattered around the map as static objects. You (or someone else) needs to dig them up using a Silverwastes Shovel, then everyone can use a key and unlock them for their own loot.
Silverwastes Shovels are gotten entirely through doing events in the Silverwastes, and given out at random.
Overall, the general SW farming process goes a little something like this…
Farm events to build up your Bandit Crest reserve and get some shovels > Buy lots of Bandit Skeleton Keys > Join a chest farm map (use LFG), follow the commander, loot chests that others dig up and use your own shovels as needed to help everyone else
Rinse and repeat.
Open those chests on a toon that is level 50-55ish, preferably light armor so you have a higher chance of getting cloth armor. Salvage the armor/weapons you get and sell the mats for $$$
You can salvage the cloth items but sell the rest. Salvaging on both a level 80 and level 50 ish breaks even, the ecto makes up for the loss from silk over linen on a level 80.
Whereas selling the ore wood salvage equipment will net you a bigger profit over salvaging. However selling everything on the TP will take some time if you have a large quantity of bags.
