Frequently asked

petup.lol is an item marketplace and PvP arcade for Roblox collectors. Buy Adopt Me pets and Murder Mystery 2 knives and guns outright, or put items you already own up against other players in Case Battles, Coinflip and the Upgrader.

With your Roblox account, through Roblox's own OAuth screen. We never see your password, and we will never ask for your account login cookie — anyone who does is trying to steal your account, and handing it over gets you banned by Roblox.

Pick the items you want to deposit and we create a ticket. One of our bots sends you a trade in game; once you accept and the trade confirms, the items are valued against the live price sheet and your balance is credited. Nothing is credited before the trade completes.

Open your inventory, pick what you want back, and request a withdrawal. Those items lock immediately so they can't be wagered while a bot is sending them. Withdrawals are processed in the order they arrive and there is no minimum.

Values track community trade data and are refreshed continuously. The number on a card is the number your item is credited at, so a deposit and an immediate withdrawal return the same items.

Yes, and you don't have to take our word for it. Before any round, we publish the SHA-256 hash of a secret server seed. Your client seed is mixed in and each round consumes a nonce. When the seed is rotated we reveal it — hash it yourself and check it matches what we published. Because the commitment comes first, no account setting or staff flag can change an outcome without breaking a hash anyone can verify. There's a public verifier on the fairness page.

Eight percent. Case prices are derived from the pool's expected value rather than set independently, and every case card shows both its price and its EV so you can see exactly what the edge is. The Upgrader applies the same 8% to your odds.

Two to four players each pay the same entry and open the same case the same number of times. The highest total pull value takes every item opened in the battle. One seed covers the whole battle, and each pull uses its own cursor, so the entire thing is reproducible from three published values.

Yes. petup.lol is for users aged 18 and over. Wagering features are not available to anyone under 18, and accounts found to be underage are closed with items returned.

Every gem you wager counts toward the weekly race. The top ten by volume split the prize pool, and the board resets on Monday at 00:00 UTC.
