Swap.gg
Instant-sell runs through Skinsback's backend, not its own - confirmed on skinsback.com's own client list.
Swap.gg does bot-driven swaps and instant-buy/instant-sell on Steam inventories, with a decent-sized, established review history.
The instant-sell margin runs wide - roughly -48%, among the widest spread in this comparison. Deposit options are broad, withdrawal is limited to basically one route.
We don't have instant-sell data for swap.gg: its instant-selling runs through Skinsback's infrastructure rather than a swap.gg API we can reach directly - swap.gg's own logo is in Skinsback's client showcase.
Confirmed on skinsback.com: swap.gg is listed among the storefronts running on Skinsback's backend, alongside lis-skins.com, Skin.land, and CS.Deals. See the Skinsback page →
