Underdog Rips: the disclosure lives at the supplier, not the storefront
Underdog’s help centre gives you a three-day window and no buyback rate. Phygitals, the third party that sources, vaults and ships every card, documents 85% of FMV in USDC, third-party valuations, provable fairness — and a buyback window that can be 30 minutes.
- Odds published
- Expected value published
- Short clock
Underdog states no buyback percentage and no payout form anywhere we could read. Phygitals documents “the standard buyback rate is 85% of FMV,” paid in USDC, with windows of 30 minutes for standard cards, 3 days for sealed product and 7 days for inventory cards — and once a window closes “the offer is permanently removed.”

Two documents, one product
Most platforms on this site are one company making one set of claims. Underdog Rips is a storefront on somebody else’s rails, and the two parties document the product very differently.
| Underdog’s help centre | Phygitals’ documentation | |
|---|---|---|
| Buyback rate | “The price offered” — no figure | “The standard buyback rate is 85% of FMV”; enhanced rates badged before purchase |
| Payout form | Not stated | “All buyback payouts are denominated and paid in USDC”, direct to a wallet |
| Window | 3 days, then auto bought back | 30 minutes standard, 3 days sealed product, 7 days inventory |
| Valuation | Not stated | “Industry-standard pricing providers for graded collectibles”, fixed at the pull |
| Odds | “Odds up front” in the announcement | “The odds of winning specific value groups” plus “the average expected value (EV) of your play” |
| Fairness | Not addressed | Distributions form part of a provably fair record, with verification documentation |
Underdog’s three days matches Phygitals’ sealed-product tier exactly, which suggests Rips runs on that configuration rather than the 30-minute standard one. That is an inference from two documents, not something either party states, and we flag it as such.
The practical problem is the same either way: a buyer reading Underdog’s own help pages cannot find out what a sell-back pays or in what form. They have to know Phygitals exists, find its documentation, and then assume it applies.
What the supplier does unusually well
Set aside where it is published and the Phygitals disclosure is among the better architecture in this category.
- Valuation is outsourced. FMV comes from “industry-standard pricing providers for graded collectibles” rather than an in-house estimate. Only Fanatics otherwise does this, and it is the single most important structural fix available in this category — it removes the conflict where the party paying the buyback also decides what the card is worth. Phygitals does not name the providers, where Fanatics names Card Ladder, so it is a step short.
- An expected value is shown per pack. If the figure is really there at the point of sale, that is the Courtyard standard, and only four platforms here meet it.
- A provable fairness claim with documentation. Rarity distributions are part of each opening’s verifiable record. Rip Station explicitly disclaims this; Phygitals leans into it.
- The buyback rate can be better than standard. Enhanced rates above 85% exist and are badged before purchase rather than discovered after.
The 30-minute window is the thing to watch
“The buyback window begins the moment your pack opening is complete”
Phygitals documents a 30-minute buyback window on standard cards. Once it closes, “the offer is permanently removed.” For comparison, we have called Pickem’s three hours the tightest decision window in the category across nineteen pages. Thirty minutes would be six times tighter.
Underdog’s own help centre says three days for Rips, and three days is a perfectly reasonable window. But if you use Phygitals directly, or if Underdog ever runs a standard-card pack, the clock is half an hour from the reveal — and the countdown starts while you are still looking at the card.
What we could not establish
This page is thinner on numbers than it should be, and it is worth being explicit about why.
| Pack prices | Not published. The terms say “various price points as displayed on the platform” |
|---|---|
| Actual odds | Claimed by both parties; we could not reach a page showing figures, so nothing is verified |
| Which buyback applies | Underdog states none; Phygitals’ 85% may or may not be what Underdog pays |
| Payout form on Underdog | Phygitals pays USDC to a wallet; whether an Underdog user receives USDC or an Underdog account balance is unclear |
| States | “Not available in all states” with no list we could find |
| Age | Not established for Rips specifically |
Underdog is a large, well-known operator, and that cuts both ways here. It brings a mainstream audience to randomised card packs, and it is the kind of company that could set a disclosure norm for the category simply by publishing the rate on its own help pages. Right now it publishes less about this product than several platforms a hundredth its size.

Why this page has no rating
We have verified no figure on this page from the platform a buyer actually transacts with. No pack prices, no odds tables, no stated buyback rate from Underdog itself. Everything numeric here comes from the supplier’s documentation and may or may not describe what an Underdog customer gets. That is not enough to score, and we would rather say so than extend Underdog’s reputation to a product we could not read. Our methodology explains why.
If you have opened an Underdog Rips pack and can screenshot the odds display, the EV figure, or a buyback offer with its percentage, that is what this page needs.
Frequently asked
How long do you have to decide on an Underdog Rips pull?
Three days, per Underdog's own help centre: you have three days from opening to redeem, hold or sell, and after that the card “will automatically be bought back.” You can choose only one path per card, and once chosen it “cannot be reversed.” Holding costs nothing during the window. Note that Phygitals, the third party powering the product, documents three different windows depending on card type — 30 minutes, 3 days or 7 days — and Underdog's three days matches its sealed-product tier.
What does Underdog Rips pay for a card?
Underdog does not say. Its help centre describes selling back “at the price offered” and states no percentage and no payout form anywhere we could read. Phygitals' own documentation says “the standard buyback rate is 85% of FMV,” that some packs carry enhanced rates shown as a badge before purchase, and that “all buyback payouts are denominated and paid in USDC” to a wallet. Whether that is what reaches an Underdog account, or whether Underdog credits its own balance instead, we could not confirm.
Who decides what an Underdog Rips card is worth?
Not Underdog, and this is the most interesting thing about the product. Phygitals says fair market value is “sourced from industry-standard pricing providers for graded collectibles” and fixed at the time of the pull. That makes this one of only two platforms we track that outsources valuation to a third party — Fanatics, which uses Card Ladder, is the other. The providers are not named here, which is a step short of Fanatics.
Does Underdog Rips publish odds?
It says so. Underdog's own announcement describes packs with “odds up front,” and Phygitals says it displays “the odds of winning specific value groups in each pack” along with “the average expected value (EV) of your play.” We could not reach a page showing actual figures, so everything on this page about odds is a claim we have not verified. An EV shown per pack would put it alongside Courtyard and SwishX if confirmed.
Is Underdog Rips provably fair?
Phygitals says its rarity distributions form part of each opening's provably fair record and publishes separate verification documentation. If that holds up, it is the second platform we track making a cryptographic fairness claim, after Clutch Packs. It is also a direct contrast with Rip Station, which states plainly that its published odds are “not a cryptographic proof of fairness.” We have not run a verification ourselves.
Where is Underdog Rips available?
Not everywhere. The terms say Rips are “not available in all states” and cards ship only to US addresses, but we could not find a published list of which states are included or excluded. Underdog's main fantasy product has its own state-by-state availability that differs by contest type, so do not assume the Rips footprint matches it. Our by-state page records only restrictions we can source.
