Blockaid Traces $9.3 Million Exploit at Flow Lender More Markets
More Markets lost 15.5 million Wrapped Flow (WFLOW) to an exploit on Flow EVM on Monday. Security firm Blockaid put the initial impact at $9.3 million.
The lending protocol has not confirmed any loss. Its team said it is looking into the claim and will publish findings once the review is complete.
What Blockaid Traced Onchain
More Markets is a non-custodial lending market on Flow EVM built by More Labs. Blockaid said an attacker combined an Ankr bonded liquid staking token with the protocol’s Efficient Mode setting to drain the mFlowWFLOW reserve.
The firm published the exploit transaction, the contract deployment, and 11 follow-up transfers. It also names the attacker address, a helper wallet, and the affected pool.

The attack lands at the end of a punishing stretch for crypto protocols. Cronos halted its blockchain on August 30 after identifying an exploit at Tectonic, its largest lending market. Last week, Moonwell lost an estimated $8.7 million.
DefiLlama data records 37 hacks in August, totaling roughly $140 million. Lending protocols account for the bulk of that figure.
