Score breakdown — 5 of 9 criteria rated (preliminary)

5 of 9 criteria are assessed, covering 54% of the declared weight. The remaining weight is redistributed proportionally rather than counted as zero.

Fees & costs8.5/1027.78% (declared 15%)
The "How ParamX works" page (paramx.xyz/docs, read 30 Sep 2026) says the fee is "0.30% of a fill's value, paid only by the taker". A resting maker order "pays nothing". There are "no deposit, withdrawal or gas fees from ParamX", although card and cross-chain providers may charge their own fees, shown before confirmation. A flat 0.3% of value is below Novig's and Predict.fun's typical taker cost (both 8.0). One caveat: ParamX runs its own market maker from an ordinary account to quote every tile, and the spread it quotes is not documented.
Regulation & trust2.0/1027.78% (declared 15%)
The Terms of Service (effective August 11, 2026, in the app at paramx.xyz, read 30 Sep 2026) name no entity. The Privacy Policy in the same app says the interface "is made available by FIN AI LLC, a company organized under the laws of Panama", and that the services are provided from Panama. The app shows "we can't offer this to US/UK persons". No licence is claimed. The docs' "Trust model" section is unusually candid. It says the operator is needed for deposits, withdrawals and fills. A 2-of-3 admin multisig can upgrade the contract and "emergency-liquidate" a contract to a fixed address. The oracle is ParamX's own. A named operator with terms but no licence falls at the low end of the 2–3.5 band.
Market variety3.0/1022.22% (declared 12%)
The docs (read 30 Sep 2026) describe only price-touch tiles: a contract pays $1 if an instrument trades inside a price range during a time window. The instruments are crypto (priced from Coinbase: BTC, ETH, SOL, XRP, ZEC, HYPE appear in the app), US stocks and ETFs, and CME futures (priced from Massive market data). That is several asset classes but a single contract type tied to price feeds, with no event questions. So it rates at the top of the 1.5–3 band.
Resolution4.0/1014.81% (declared 8%)
The "Prices and settlement" and "Trust model" sections (read 30 Sep 2026) document the process. About five minutes after a window ends, ParamX's oracle signs a proof: either a specific trade inside the tile ("which you can check against the source market's own history") or a signed "not touched" statement. The contract then checks the signature, range, window and instrument. The docs admit "a dishonest oracle could sign a false trade or a false 'not touched'", and that on market holidays tiles "will settle as not touched". No dispute or appeal route exists. The admin can rotate the oracle after a one-day delay. That is better disclosed than FanDuel (3.5), but it is still operator-resolved with no appeal.
Bonuses & promos3.0/107.41% (declared 4%)
The app (read 30 Sep 2026) has an "Invite & earn" page: "Earn {pct} of the trading fees paid by everyone who signs up with your link", with a minimum claim and rewards claimed manually via Discord. The percentage is filled in dynamically and was not visible in the static page text. There is no welcome offer for traders. A referral-only programme with an undisclosed rate and manual claims rates below Polymarket intl's 3.5.
