SentinelTX’s analysis records 726,307.1011248019 BSC-USD paid to the exploit-signing address, followed by a bridge route and Ethereum settlement activity. The reported loss, mechanism, and final ETH balance require different levels of qualification.
This ChainBounty review draws on SentinelTX’s analysis of case CASE-20261024-NEM1. Recorded transfers, reported figures, and analytical assessments are distinguished throughout.
The investigation concerns a BNB Smart Chain token called NEM, identified in the analysis as token contract 0x9cf0e3ad4efa7ab602d7b5a38c55795cfa777777. The name NemTokenV2 comes from press reporting cited by SentinelTX. The analysis establishes no connection to the separate NEM/Symbol blockchain project.
Its central finding is a transaction dated October 21, 2026, at 03:28:50 UTC, in BSC block 128,866,147. The signing address, 0xfd929b0f270dfea6c4827262b4e2bf6ea50fe9b6, called an attack contract, 0x5e6d1f40be466dd2facc94a26818948ecd3b1ca2. SentinelTX classifies the resulting payment of 726,307.1011248019 BSC-USD to the signing address as confirmed. The full transaction hash and address register appear in the appendix.
The widely reported loss of approximately US$821,920 is a separate source claim. It is not interchangeable with the recorded payment of 726,307.1011248019 BSC-USD. SentinelTX does not establish a complete reconciliation between the reported loss and the recorded proceeds, so neither figure should be substituted for the other.
The analysis distinguishes the October 21 execution date from the October 22 alert and publication date. Its October 24 ETH balance observation is later still. These dates describe different events, not competing dates for one transaction.
All transaction times below are UTC on October 21, 2026, as stated in the source analysis.
The analysis’s later balance read is dated October 24. It records approximately 296.19 ETH remaining at the signing address on Ethereum, with no outbound ETH in the retrieved ledger. This is an unverified historical balance observation, not a claim about the address's live balance when this article is read.
SentinelTX assesses the incident as a token-accounting and liquidity-pool reserve manipulation exploit. Its proposed sequence depends on reporting that transfers into the pair count as sell volume, while a function named flushLpSellRecycle() burns NEM held by the pair. Repeated skim() calls are reported to return the operator's tokens as the pool's NEM holdings shrink, before the retained inventory is sold against the altered pool state.
That sequence is an assessment in the analysis. The token's source code and the individual burn, reserve, and skim-related events were not decoded there. The proposed sequence is therefore not an event-by-event proof of the vulnerability.
The reported count of 42 cycles has a limited technical anchor: the transaction's calldata ends with 0x2a, or decimal 42. Without ABI decoding, that word does not by itself prove what the parameter controls or how many cycles executed. Likewise, 1,608 logs show extensive transaction activity in the analysis, but an unclassified log count cannot independently establish 42 repetitions of a particular mechanism.
Flash-borrowed liquidity is another inference. SentinelTX describes large, same-transaction BSC-USD round trips involving Venus vUSDT, PancakeSwap, and two unlabeled contracts. It did not decode loan origination and repayment events. The analysis assigns the direct loss to the affected pair's liquidity providers, but does not provide a reconciled reserve-loss calculation matching the reported US$821,920.

Diagram 1. Read the numbered rows from top to bottom, and each row from left to right. The analysis assesses a skim-and-burn reserve-desynchronization loop: transfers into the LP register pending sell volume, flushLpSellRecycle() burns NEM held by the pair, skim() returns the operator’s tokens, and repeated rounds precede a final inventory sale. This is a reported mechanism, not an event-by-event decoded proof. The reported 42-cycle count is only partially corroborated by the raw calldata word 0x2a, not ABI-decoded; no exact loop count is encoded in this schematic. Equal-width dashed arrows summarize the reported sequence, not token quantities.
Slate labels identify the stated actions; arrows indicate the relationships written in each row, not quantities.
NEM token: 0x9cf0e3ad4efa7ab602d7b5a38c55795cfa777777. LP/pair: 0x840e19dcca541ee0b55a3c67e900a39d523b12b8; its victim-pool role is a source claim consistent with the analysis’s records. Attack contract: 0x5e6d1f40be466dd2facc94a26818948ecd3b1ca2. Signer/proceeds recipient: 0xfd929b0f270dfea6c4827262b4e2bf6ea50fe9b6; operator identity is not established.

The funder, 0x96cb6bec56e43b2f16c05e1af4776fbc7b9713b5, supplied the initial gas and the NEM inventory later committed to the attack contract. Its first-seen date is October 20 in the analysis. The repeated funding, inventory transfers, and timing support SentinelTX's assessment that the two addresses were operated by the same actor or closely coordinated actors. Common ownership is not proven, and no person or organization is identified as the operator.
Six helper contracts reportedly returned their NEM balances short by exactly 1 NEM each. SentinelTX interprets the similar interactions as rehearsal against mainnet conditions, an operational assessment rather than a separate finding of intent. Six listed WBNB recipients are classified as probable helpers; their mapping to the six creation records is not established.
The inventory has another upstream lead. An unlabeled contract, 0xaee6b842f94281653dde98da97debd93007de2a1, reportedly sent the funder 780,757.29 NEM across 45 transfers. In itemized examples, NEM arrived with BSC-USD and the same BSC-USD quantity was returned shortly afterward. SentinelTX suggests a reward, staking, or distribution mechanism as a possible explanation, but the contract's function was not decoded.
The contract’s ownership and any additional loss remain unproven. Shared first-seen dates with the token and pair do not establish ownership. The analysis also records a post-exploit sale by the funder through a TransitSwapRouterV5-labeled route, but its relationship to any additional loss remains unresolved.
The analysis traces a BSC stablecoin payment into the router, a correlated Relay delivery on Ethereum, and three transfers to CoW Protocol settlement: 250,000.0 USDT, 250,000.0 USDT, and 225,384.763364 USDT. Each Ethereum quantity carries the source's unverified-amount qualification.
SentinelTX attributes the difference between the routed and delivered quantities to bridge fees and spread. That remains an assessment: the amounts are in different token denominations, the destination quantity is unverified, and no itemized fee accounting is provided.
The Ethereum native ledger is reported as four inbound transfers totaling 296.192678708450769578 ETH, no outbound ETH, and 0.000205413793461084 ETH used for gas. Its resulting balance is 296.192473294657308494 ETH. All of these ETH figures are unverified. The counterparties and hashes of the four incoming ETH transfers are not itemized in the analysis, so the article cannot supply a complete leg-by-leg conversion reconstruction.
The recorded endpoint is an address holding native ETH. It is not evidence of fiat cash-out. The WBNB contract's Binance-related label does not make it a Binance customer deposit address, and the CoW settlement contract is described as a non-custodial venue. No custodial exchange deposit is established by the analysis.
The BSC exit also contains an EIP-7702 authorization that delegates execution to another address. SentinelTX records that field but treats its batching interpretation as an assessment. Delegation on Ethereum is not established. These technical roles do not identify a beneficial owner.

Diagram 2. Read the numbered rows as the reported route, not three independent totals. The analysis records 726,307.1011248019 BSC-USD from the attack contract to Recipient A and the same quantity forwarded through the Socket router on October 21. A correlated Relay record reports delivery of 725,384.763364 USDT to the same address on Ethereum; that destination quantity is unverified. Three CoW settlement legs follow. The October 24 balance read reports 296.192473 ETH, while the analysis’s ledger calculation gives 296.192473294657308494 ETH; both are unverified. Display values are approximate. The four inbound ETH counterparties are not itemized, so the final arrow summarizes the analysis’s conversion sequence and later balance, not a fully reconstructed transfer leg. Equal-width arrows are schematic; the BSC-USD, USDT and ETH values are not summed or treated as interchangeable loss amounts.
Slate: 1 · BSC collection and router exit; Sage: 2 · Relay delivery and CoW swaps; Amber: 3 · Later Ethereum balance read. Equal-width arrows show stated routes, not quantities.
Recipient A on both chains: 0xfd929b0f270dfea6c4827262b4e2bf6ea50fe9b6. BSC attack contract: 0x5e6d1f40be466dd2facc94a26818948ecd3b1ca2. Socket router: 0x50cfe7c1938db66a1a6d2e86d36f39fbef3d5c4a; the analysis’s literal attribution includes “Socket OpenRouter (Ethereum)” despite the BSC transaction. Relay-labeled Ethereum sender: 0xb92fe925dc43a0ecde6c8b1a2709c170ec4fff4f. CoW settlement recipient: 0x9008d19f58aabd9ed0d60971565aa8510560ab41. No operator identity or custodial exchange deposit is established.

The original source distinguishes real funding from records it classifies as suspected address poisoning. At 01:07:18, a look-alike of the funder sent 0.007 units of a token whose symbol imitated BNB using non-Latin characters. Its amount mirrored the real gas funding, but the analysis found no value-bearing onward movement and excluded it.
A mirror-image record named a look-alike of the signing address. The two full addresses are distinct, and the mirror-image record’s transaction hash is not provided. Neither poisoning record is used as evidence of common control or an economic connection.
The analysis also excludes unsolicited airdrops as spam, including two tokens recorded with a burn-address emitter and other tokens with miscellaneous names. An appearance in a transaction history is not enough, within the source's own methodology, to include a transfer in the traced proceeds.
SentinelTX's practical priority is the last recorded Ethereum holding and any later onward transfer. The analysis describes potential investigative leads in the funder's upstream financing and in request metadata that infrastructure operators might hold. The availability of that metadata and any resulting recovery action are not established.
The source rates near-term recovery prospects as moderate, but that is its expert assessment, conditional on an unverified balance observation. It is not a recovery probability, an assurance that funds remain available, or a promise that a service provider can freeze native ETH. The analysis’s legal-process and negotiated-return suggestions require case-specific decisions by the affected parties and their qualified advisers; they are not legal instructions from ChainBounty.
Important analytical limits remain: the mechanism has not been decoded cycle by cycle, flash liquidity is inferred, the funder's earlier history is not itemized, two in-transaction counterparties lack an onward trace, and the four ETH receipts lack individual detail. The reported loss remains unreconciled with the recorded proceeds. The analysis does not specify its complete query windows; its conclusions are limited to the records discussed. No personal identity, custodial deposit, or connection to NEM/Symbol is established.

Figure 3. The analysis supports a reported route from BSC proceeds through Relay to Ethereum and CoW settlement, subject to its quantity and balance qualifications. Approximately US$821,920 is a publicly reported loss claim; 726,307.1011248019 BSC-USD is the analysis’s recorded proceeds payment. These differently denominated figures are not directly interchangeable, and the source does not reconcile the loss gap. The mechanism is not decoded cycle by cycle; no personal or organizational identity, custodial exchange deposit, fiat cash-out, or connection to the unrelated NEM/Symbol project is established. The October 24 balance observation of 296.192473 ETH remains unverified and is not a statement of a live current balance. Rounded display values are approximate.
Slate identifies section headings, not certainty or risk.
The balance observation and Recipient A role refer to 0xfd929b0f270dfea6c4827262b4e2bf6ea50fe9b6 on Ethereum, not the separate poisoning look-alike identified in the analysis.
