Blockaid: Limit Break Payment Processor V2 drains ~$1.7M in NFTs at zero price
By Node Zero
September 25, 2026
Security firm Blockaid said on September 25, 2026 that Limit Break on Ethereum is under ongoing attack through its Payment Processor V2 contract, with about $1.7 million in NFTs stolen across roughly three transactions—attackers impersonating holders and buying previously operator-approved NFTs at a zero price. ChainCatcher and PANews carried Blockaid’s monitoring note; Phemex’s English wrap repeats the same figures and the revoke-now warning. That malicious-operator path is unused Dev Pulse for Sep 25 OC: distinct from this morning’s Magic Eden–linked white-hat market reports (LN 9707), which tracked Quit’s claimed rescue of 3,832 NFTs rather than Blockaid’s active drain tally.
What the exploit claims to abuse. Blockaid says Payment Processor V2 is used to impersonate NFT holders and purchase authorized inventory at zero cost. Users who set Payment Processor V2 as an NFT operator are the exposed set; Blockaid stresses that simply canceling orders or resetting a master nonce does not lift that operator permission—you must revoke the operator approval itself. Limit Break’s open-source Payment Processor stack was built for ERC-721/1155 trading with on-chain royalty rails—creator-first exchange plumbing that many marketplaces and collections wired into listing flows. Attribute the zero-price impersonation mechanic and the ~$1.7 million / three-transaction snapshot to Blockaid’s incident note via ChainCatcher and PANews, not as a full public post-mortem or patched bytecode commit from Limit Break itself.
How this sits beside the Quit / Yuga white-hat thread without rehashing LN 9707. TokenPost and Phemex separately report Yuga Labs CEO Michael Figge confirming Quit’s white-hat rescue and Quit naming holding address 0x71cF3f5724bD2B72Ef6464992aCd26216DE7fe33 as safe pending return. Quit also told users to revoke Ethereum Payment Processor V2 and ApeChain Payment Processor V3 approvals via revoke.cash. Desk split: LN 9707 filed the ME-linked movement and unconfirmed marketplace framing; tonight’s unused angle is Blockaid’s ongoing $1.7 million malicious drain via the same processor family—plus the operator-revoke technical instruction that collectors still need if they never touched the white-hat wallet. Treat white-hat rescue inventory and malicious zero-price buys as parallel tracks on one vulnerable approval surface until Limit Break or Blockaid publishes a unified timeline.
Why Dev Pulse 57 instead of another Rug Room hit. Sep 25 already opened Rug Room 52 on Bitget’s spoofed-backend method (LN 9704) and Marketplace Watch 58 on the ME white-hat reports. Payment Processor V2 is a creator-royalty exchange contract under active exploit—protocol surface, approval model, and revoke semantics—so it lands on unused Dev Pulse with Latest News 16 and Editor’s Pick 13 (EP 3/5). Solana ETF $32.8 million and Bitcoin’s sixth-day $191 million print stay held as weaker NFT-native near-echos of prior ETF desks.
Collector hygiene right now. Open revoke.cash (or your wallet’s approval manager) on Ethereum and revoke Payment Processor V2 as an NFT operator; if you used ApeChain marketplace rails, revoke Payment Processor V3 there too per Quit’s TokenPost-carried warning. Check both operator approvals and any leftover marketplace permits before you reconnect a vault or cold-adjacent hot wallet. Do not send NFTs or ETH to any DM’d “recovery” address—even one mimicking 0x71cF. Do not assume canceling open bids cleared operator rights. Watch whether Blockaid’s $1.7 million / three-tx tally rises, whether Limit Break publishes a patch or pause, and whether Quit’s white-hat inventory actually returns onchain after risk clearance.
What not to invent: a confirmed Limit Break blog post we have not seen, a full list of drained collections, that every ME user is automatically drained, that the white-hat $1.5 million TokenPost valuation equals Blockaid’s $1.7 million malicious total, or that ApeChain V3 has the same dollar loss as Ethereum V2. Stick to Blockaid via ChainCatcher/PANews/Phemex for the ongoing zero-price operator drain, and keep Quit/Figge confirmation as adjacent revoke context—not a reprint of LN 9707.
Bottom line: Blockaid says Limit Break’s Ethereum Payment Processor V2 is under ongoing attack, with about $1.7 million in NFTs taken at zero price across roughly three txs—revoke that operator approval now; unused Dev Pulse for Sep 25 OC.
