Fact-check findings
What an automated fact-checker found when it re-read Vesper Finance against the sources the page cites. Only the most recent review is shown.
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.

“As of early 2026, Vesper Finance continues to operate with approximately $48 million in TVL, its highest level since 2022, supported by expansion to Base and Optimism.”
reviewerTVL of approximately $48 million, highest since 2022DefiLlama blocked. Also, the summary says $48-55M and the timeline says ~$55M in Nov 2025, so the figures are internally inconsistent.

- #4[partially supported][awaiting moderator]in the timeline
“Vesper governance approves $156,833 treasury allocation to remediate Sonne-related pool debt; all Optimism pools restored to operation.”
reviewerGovernance approved the $156,833 treasury allocation on 2024-05-21Amount and date confirmed, but the cited thread is a discussion and shows no approval or restoration. The section's 'approved via a community governance proposal' and OP/USDC/wstETH pool names were not verified.

- #5[confirmed][no action needed]in section: November 2021 Oracle Manipulation Exploit ($3.37 Million)
“The attacker funded the attack with 100 ETH sourced from Tornado Cash.”

Fairyproof says about 56.82 ETH swapped (page says 58 ETH) and does not mention TWAP or the 0.05% pool; the Vesper Medium post (403) could not be read. The $3.37M net figure was not independently verified.
