MarketGuard for Hypixel SkyBlock
by Pankraz01
MarketGuard for Hypixel SkyBlock blocks a Create BIN Auction or a Bin Auction View purchase when its price sits far from the current Lowest BIN.
What it does
Two checks run on the Auction House. When a BIN auction is being created, the listed price is compared with the Lowest BIN, and a price well below it is stopped. When a Bin Auction View opens, the purchase price is compared the other way, and a price far above the Lowest BIN is stopped as well. Lowest BIN data is loaded in the background as soon as a relevant auction screen opens, so the check does not wait on the screen.
If a price falls outside the configured tolerance, the click is blocked and a chat message names the item and the percentage difference. Typo prices and missing zeroes are the cases this is meant to catch. The mod does not scan for scams in general; it only covers these two BIN clicks, so deliberate decisions remain possible after the warning.
The mod is a Fabric client mod. It needs Fabric API and bundles MidnightLib and Tango's Dynamic Hud Lib. Files cover game versions 1.21.10 – 26.3, and the latest file is 1.5.0+26.3 for 26.3. The code is under the GNU General Public License v3.0 only, and the source is public.
