ONE Arena review
What can you open on ONE Arena?
ONE Arena sells Pokémon, One Piece, sports cards and Riftbound packs, priced $25+. You buy a pack, reveal a card instantly, then choose what to do with it: keep it in the vault, have it shipped. Packs are paid with a crypto wallet and each card is recorded on the blockchain. ONE Arena is a crypto front-end built on another site’s card inventory.
Is ONE Arena legit?
ONE Arena sells real Pokémon, One Piece, sports cards and Riftbound cards that are held in a vault until you ship, trade or sell them. The odds and the card pool are shown before you pay.
It has no Trustpilot reviews yet, so there is little independent feedback. Tier odds and EV are shown per pack and the company is named, but the randomness method isn't disclosed and there are no reviews. Our fairness grade: B (good).
Points to read in the terms before you deposit:
- Published odds and prices may change between purchases.
- May withhold, correct or reverse off-chain rewards.
- No fixed sellback rate.
ONE Arena odds and payout
ONE Arena shows the odds of each value band before you open a pack, so you can see how often a pack pays more than its price. On average, packs return about 102.4% of their price in card market value (published by the site). Selling pulls back costs the buyback fee on top.
ONE Arena buyback, vault and shipping
ONE Arena does not publish a buyback rate. Ask support before you rip if you plan to sell your pulls. Cards you keep stay in the vault, insured, until you ask for them to be shipped, which usually costs a fee.
