Fact-check findings
What an automated fact-checker found when it re-read Splash / Optim Finance (OADA) Cardano StableSwap Exploit 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.
unverifiable
3 claimsNo source the reviewer could reach confirms or contradicts the claim.
- #2[unverifiable][awaiting moderator]in section: Splash Protocol Response and Patch
“Splash's TVL dropped approximately 27 percent to around $3.3 million in the immediate aftermath, according to reporting that cited DeFiLlama data.”
reviewerSplash's TVL fell about 27% to about $3.3M, citing DeFiLlamaNot found in the CryptoSlate or Grafa articles. The CryptoTimes article returned 403 and could not be read, so the figure may be there. - #3[unverifiable][awaiting moderator]in section: Broader Cardano DeFi Ecosystem Impact
“Cardano's overall DeFi total value locked was approximately $55 million at the time of the exploit.”
reviewerCardano DeFi TVL was about $55M at the timeThe primary cited source is blocked and the alternative cited source does not carry the figure. - #8[unverifiable][awaiting moderator]in section: The Exploit
“No attacker wallet addresses or transaction hashes had been publicly disclosed by the protocols as of the latest available reporting.”
reviewerNo attacker wallet or tx hashes publicly disclosedSplash's reconstruction exists, and the exploit was dated to 00:47-00:48 UTC, which suggests on-chain data is traceable. Absence is plausible but not checkable.
partially supported
3 claimsThe cited evidence supports part of the claim but not all of it.
- #4[partially supported][awaiting moderator]in the timeline
“Splash releases a validator patch closing the documented exploit path, addressing the missing reserve non-negativity check, the unidirectional fee bound, and the absent swap-direction enforcement.”
reviewerSplash released the patch on 2026-09-15A patch exists, but no source fetched dates it to Sept 15. The Sept 15 entry date is inferred, not sourced. - #5[partially supported][awaiting moderator]in section: Optim Finance Response and OADA Holder Impact
“A secondary Minswap pool reportedly held approximately 1,763,923 OADA against only 45,751 FLDT at the time of the attack”
reviewerMinswap pool held 1,763,923 OADA vs 45,751 FLDT at the time of attackNumbers are right; the timing of 'at the time of the attack' is imprecise. The page also calls the pool 'secondary' where the source names it as the OADA/FLDT pool. - #9[partially supported][awaiting moderator]in section: Background: Splash Protocol and Optim Finance
“Optim Finance received funding through Cardano Project Catalyst Fund 11 for the OADA product line.”
reviewerOptim received Catalyst Fund 11 fundingA Fund 11 proposal for OADA exists per search results. Whether it was funded was not confirmed, and the page cites no source for this claim.
confirmed
3 claimsThe cited evidence supports the claim as written.
- #1[confirmed][no action needed]in section: The Exploit
“On September 13, 2026, a single actor executed two on-chain transactions against Splash Protocol's ADA/OADA StableSwap pool on the Cardano blockchain, draining 2,434,648 ADA and 1,988,222 OADA.”
reviewerTwo transactions drained 2,434,648 ADA and 1,988,222 OADA on Sept 13, 2026Amounts, deposit, net loss and pool remainder (10 ADA, ~1.44M OADA) all match CryptoSlate. - #6[confirmed][no action needed]in section: Optim Finance Response and OADA Holder Impact
“In a September 15 update, Optim Finance stated it was indexing the chain and compiling a full accounting of impacted addresses and assets.”
reviewerOptim paused on Sept 13 and gave a Sept 15 update with no redemption announcedThe 06:57 UTC announcement time could not be checked because the CryptoTimes page was blocked. - #7[confirmed][no action needed]in section: Technical Root Cause
“Third, the validator did not enforce the direction of a swap.”
reviewerThree missing validator checks, per SplashSplash's own disclosure is relayed by CryptoSlate. The page's wording that CryptoSlate said 'a reserve-domain check or two-sided fee limit would have prevented' is a fair paraphrase of Splash's statement, but it is presented as a direct quote.
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.
