SplatNet 3 is an online service for Splatoon 3, which contains features like checking battle records and ordering special in-game gear from the SplatNet Shop, as well as Wandercrust. It is a sequel to SplatNet 2 and was announced in the Splatoon 3 Nintendo Direct on 10 August 2022. Like its predecessor, it was made available through the Nintendo Switch Online app when Splatoon 3 launched. A Nintendo Switch Online membership is required to use this service.
There are four main tabs, which are always accessible on the bottom of SplatNet 3: Home, Schedule, Battles, and Salmon Run.
This is the home and start-up page after opening SplatNet 3. On the top of the page, a series of changing scrolling tabs advertises Exclusive SplatNet Gear, Freshest Fits, Battle Records, and Salmon Run as well as other tabs that are time specific like Splatfest or completion specific like Wandercrust. Directly underneath is an option labeled Online, which displays the Nintendo Switch Online User Icons of the player's currently online friends. Thirteen other labeled page icons appear underneath this, with SplatNet Shop, Freshest Fits, and History having larger icons than the other ten. 
The SplatNet Shop is an online retail service that allows players to order special in-game gear not sold in shops using their in-game cash. This version of the gear shop hosts the The Daily Drop, and appears to have a daily stock themed after a particular gear brand. At the bottom of the page, the brand's favored ability is displayed.
After ordering from SplatNet, the player may meet Murch in Splatsville or Spyke in Inkopolis Plaza to pay for the ordered gear. Unlike ordering gear from another player, gear ordered from SplatNet can be bought immediately and is kept indefinitely until purchased or removed.
This feature allows players to view their Freshest Fits. Players can edit their Freshest Fits and create new ones if they have the space. While viewing a Fit, the player can see the total number of ability points granted by the gear in that Fit.

Further down is a detailed list of battles showing if the player won or lost, the stage, how many points they had, and what weapon they used, as well as the same match information for other players in the match. The list of battles is divided by what mode was played. Unlike in Splatoon 2, this information is also viewable in-game instead of exclusively available in SplatNet. Furthermore, players can anonymize other player names if they want to share the battle stats by tapping on the top of the battle where the player has won or lost.
