Fact-check findings
What an automated fact-checker found when it re-read Polkadot 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.
disputed
1 claimThe reviewer could not reconcile the claim with the evidence it cited. This is a lead, not a ruling that the claim is false.

“Gavin Wood cycled out and back as Parity CEO twice.”
reviewerGavin Wood cycled out and back as Parity CEO twiceReporting documents exactly one full cycle (stepped down 2022, returned 2025), not two. The page also omits the August 2025 return from its Leadership Instability narrative and timeline entirely, making the section read as if Wood never returned to the CEO role.Proposed correction (not yet applied)Gavin Wood stepped down as Parity CEO in October 2022 and returned to the role in August 2025.
unverifiable
5 claimsNo source the reviewer could reach confirms or contradicts the claim.

“Polkadot (DOT) is a multi-chain protocol founded by Gavin Wood, ranked #41 by market cap (~$2.3B).”
reviewerPolkadot is ranked #41 by market cap at approximately $2.3BMarket cap rank is inherently time-sensitive and no source could be dated precisely to confirm #41 at the time of writing; checked sources cluster around #45, in the same ballpark but not an exact match. - #6[unverifiable][awaiting moderator]in the summary
“steep ecosystem decline with active parachains dropping from 200+ to ~30”
reviewerActive parachains have dropped from 200+ to approximately 30Could not corroborate either the 200+ baseline or the ~30 current figure from an accessible primary source; a promotional late-2025 community post instead claims '50+ active parachains'. The underlying metric definition (registered para IDs vs. deployed parachains vs. active/producing blocks) is unclear and sources conflict. - #19[unverifiable][awaiting moderator]in section: Ecosystem Decline
“Of 200+ registered parachains, only approximately 30 remain active.”
reviewerOf 200+ registered parachains, only approximately 30 remain activeSame unresolved figure as flagged in the summary; could not confirm either the 200+ baseline or the ~30 active figure from a source actually fetched. - #24[unverifiable][awaiting moderator]in section: Third-Party Scams
“An alleged 'Polkadot Fund' scam reportedly took over 7 million DOT from Chinese community users.”
reviewerAn alleged 'Polkadot Fund' scam reportedly took over 7 million DOT from Chinese community usersThe page's own hedged language ('alleged', 'reportedly') is appropriate given the thin sourcing; this is a fair representation of weak evidence rather than a misrepresentation. - #31[unverifiable][awaiting moderator]in the timeline
“Polkadot ICO raises $145M”
reviewerPolkadot ICO raised $145M on 2017-10-15The $145M amount and October 2017 month are well-corroborated, but no source consulted confirms the specific date of October 15; one source instead suggests October 1.
stale
1 claimThe claim was accurate when written but events since have overtaken it.
- #28[stale][awaiting moderator]in section: JAM Upgrade
“Next-generation compute architecture (JAM) is in development with 43 competing implementations.”
reviewerJAM (next-generation compute architecture) is in development with 43 competing implementationsThe 43 figure was accurate at one point (October 2025) but more recent official reporting shows it has since dropped substantially, making the static '43 competing implementations' framing outdated.Proposed correction (not yet applied)Next-generation compute architecture (JAM) is in development; participation in the JAM Implementers' Prize fell from approximately 43 active teams in October 2025 to about 15 teams reaching the first milestone by January 2026.
partially supported
3 claimsThe cited evidence supports part of the claim but not all of it.

“Grants program, Decentralized Voices initiative, and community support channels were all shut down.”
reviewerGrants program, Decentralized Voices initiative, and community support channels were all shut downThe Decentralized Voices closure is confirmed; the other two items in this compound sentence (grants program, community support channels) could not be corroborated and may overstate the actual cuts. - #18[partially supported][awaiting moderator]in section: Ecosystem Decline
“Q1 2025 transactions down 36.9% QoQ; monthly active addresses fell 13.1%; daily active users approximately 5,000; TVL at ~1.8% of total DeFi (from 3.5% in 2021).”
reviewerQ1 2025 transactions were down 36.9% quarter-over-quarter and monthly active addresses fell 13.1%; daily active users were approximately 5,000; TVL was at approximately 1.8% of total DeFi, down from 3.5% in 2021The transaction and active-address decline figures are independently corroborated via secondary coverage of the Messari report (the primary report itself was inaccessible, returning HTTP 429). No independent source could be found for the ~5,000 daily active users figure or the 1.8%/3.5% DeFi TVL share figures, so those two sub-claims are unverifiable rather than confirmed. - #26[partially supported][awaiting moderator]in section: Regulatory Status
“ETF applications from Grayscale and 21Shares are under review.”
reviewerETF applications from Grayscale and 21Shares are under reviewThe underlying claim is true for both issuers, but the single cited source only documents the Grayscale proceeding; the 21Shares half of the claim is unsupported by the section's own citation even though independently verifiable elsewhere.
confirmed
28 claimsThe cited evidence supports the claim as written.

“an April 2026 Hyperbridge exploit minting $1B in fake bridged DOT (losses ~$2.5M)”
reviewerAn April 2026 Hyperbridge exploit minted $1B in fake bridged DOT with losses of approximately $2.5MNote the cited CoinDesk article's own URL slug/headline ("usd250-000") reflects the earlier, superseded figure; the $2.5M revision is confirmed by the Yahoo Finance source and other outlets, not by the CoinDesk piece itself. - #7[confirmed][no action needed]in the summary

“Losses were revised to ~$2.5M (10x the initial estimate).”
reviewerLosses from the Hyperbridge exploit were revised to approximately $2.5M, about 10x the initial estimateConfirmed; note the primary CoinDesk citation for this section still reflects the earlier $237K-$250K figure, so the $2.5M figure rests on the secondary Yahoo Finance source. - #10[confirmed][no action needed]in section: Hyperbridge Bridge Exploit (April 2026)

“The frozen ETH was never recovered, forcing a second fundraise in 2019.”

reviewer14,000+ fraudulent sites have been catalogued by Polkadot's anti-scam teamThe cited Medium post itself returned HTTP 403 and could not be directly re-fetched, but the figure is independently confirmed via the official Web3 Foundation press release it is drawn from. Note the figure dates to 2022; a 2025 governance proposal cites ~11,000 new scam sites identified in 2024 alone, suggesting the cumulative total is likely much higher today. - #25[confirmed][no action needed]in section: Regulatory Status

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.
