Fact-check findings

What an automated fact-checker found when it re-read ZRX (0x Protocol) against the sources the page cites. Only the most recent review is shown.

Read this first

These findings are produced by an automated reviewer, and its results vary between runs: the same page, checked three times on the same day, came back with 15%, 20% and 34% of its claims disputed, mostly because each run extracted a different number of claims. Treat what follows as leads, not rulings.

“Disputed” means the reviewer could not reconcile the claim with the evidence it cited. It does not mean the claim is false. “Unverifiable” means no reachable source settled it either way.

Nothing here changes the page on its own. A proposed correction is applied only after a human moderator approves it; until then the page reads as it did when reviewed.

The reviewer could not reconcile the claim with the evidence it cited. This is a lead, not a ruling that the claim is false.

    “The ICO distributed tokens across more than 13,000 distinct Ethereum addresses.”
    reviewerThe ICO distributed tokens across more than 13,000 distinct Ethereum addresses.Multiple independent contemporaneous sources (CoinDesk, CryptoSlate, Forklog quoting 0x's own 'thank you, 12,000 hodlers' tweet) consistently cite ~12,000 participants/backers, not 'more than 13,000'. No source for the higher figure was found.

    “with v4 approved by community governance in January 2023”
    reviewer0x Protocol v4 was approved by community governance in January 2023.None of the cited sources actually supports a 2023 date. Multiple independent sources, including 0x's own blog, place the v4 governance vote in January 2021, two years earlier than stated. This appears to be the same underlying error as the matching timeline entry.

    “2023”
    reviewer0x Protocol v4 is approved via community governance vote by over 2,300 ZRX holders, dated 2023.The holder count (over 2,300, actual 2,362) is accurate, but the date field is off by two years; the vote took place in January 2021, not 2023. Same underlying defect as the Protocol Architecture section's claim.

    “ZRX traded in the $0.21–$0.25 range”
    reviewerAs of mid-2025, ZRX traded in the $0.21-$0.25 range.The page narrows and shifts the range reported by its own cited source. This is a mischaracterization of the cited source rather than a wholly fabricated figure.

    “as of 2026 Matcha aggregates over 130 on-chain and off-chain liquidity sources across 16 chains and is reported to be among the top three DEX aggregators by volume”
    reviewerAs of 2026, Matcha aggregates over 130 on-chain and off-chain liquidity sources across 16 chains and is reported to be among the top three DEX aggregators by volume.The sole cited source for these figures is dead (see linked link_rot finding). Secondary sources give materially different source/chain counts, so the specific '130 sources / 16 chains / top three' figures could not be independently confirmed.

    “Cumulative trading volume across all 0x integrations is reported to exceed $200 billion since inception.”
    reviewerCumulative trading volume across all 0x integrations is reported to exceed $200 billion since inception.Reported cumulative-volume figures for 0x vary widely across secondary sources ($130B-$370B depending on date/source), so the page's $200 billion figure is plausible but could not be pinned down against an authoritative, dated, official figure. The same figure appears in the page summary.

  4. #17[unverifiable][awaiting moderator]in section: Token Utility and Governance
    “$2.40 (April 2021)”
    reviewerZRX reached approximately $2.40 in April 2021, nearly matching its 2018 all-time high.The cited source (Gate Wiki) does state this figure, but a dated contemporaneous snapshot and every ATH aggregator checked are inconsistent with ZRX reaching $2.40 in April 2021. Could not obtain month-level CoinGecko/CoinMarketCap historical data to settle this conclusively, so it is marked unverifiable rather than disputed. The identical figure also appears in timeline[6].

    reviewerA fake ZRX ICO scam was flagged by the official 0x team in April 2020, warning users not to send funds to the impersonation campaign.Plausible and low-stakes claim, but could not be independently confirmed because the cited tweet is behind X's access paywall for this review's tooling.

    reviewerA thread titled 'ZRX Ended Up Being a Scam' on the official 0x governance forum represents a community grievance; the post is no longer accessible.The page already appropriately hedges this claim as unverifiable; flagged here for completeness rather than as a defect.

2 claims

The cited evidence supports part of the claim but not all of it.

  1. #11[partially supported][awaiting moderator]in section: Protocol Architecture and Ecosystem
    “The team launched Matcha, a DEX aggregator front-end, in June 2020”
    reviewer0x launched Matcha, a DEX aggregator front-end, in June 2020.Sources diverge on the exact month: 0x's own April 2020 materials versus The Block's June 30, 2020 launch article. The page's June 2020 date is defensible (matches The Block) but conflicts with other 0x-sourced materials describing an earlier soft launch; not confidently correctable without the exact original 0x announcement.

    “Warren holds a background in applied physics, mechanical engineering, and robotics, and previously contributed to projects including Basic Attention Token and Brave.”
    reviewerWarren has a background in applied physics, mechanical engineering, and robotics and previously contributed to Basic Attention Token and Brave.The BAT connection is real but was a brief technical-advisor role, not an employee/contributor role at Brave itself; the page's phrasing slightly overstates the depth of involvement with 'Brave' as a separate project.

How this fits together. The reviewer reads the published page and its cited sources and records one finding per claim. A human moderator decides whether each proposed correction is applied; those decisions, and the score changes they cause, appear in the audit log. Earlier review runs are not shown here; only the latest reflects the page as it stands.
