More Markets Lending Reserve Drain on Flow EVM

What happened

Security firm Blockaid flagged a suspected exploit on More Markets, a lending protocol on Flow EVM, on 31 August 2026, saying an attacker combined Ankr’s liquid staking token ankrFLOW with Aave V3 efficiency mode to overborrow against the mFlowWFLOW reserve. More Markets said the same day that it was investigating a claim it had been exploited. DefiLlama records the loss at $410,000, an unbacked mint.

Two figures are in public and they do not agree. Blockaid’s original alert cited a detected impact of about $9.3m; that post has since been deleted by its author, so the figure cannot be checked against its source and is not used here. DefiLlama’s hacks database carries the incident under Ankr on Flow at $410,000, classified as token and share accounting, unbacked mint, and that is the figure this log records. The gap between the two is unresolved in public. A reported follow-up from More Labs disputing the exploit could not be found and is not relied on.
