Bitmine said this week it holds $11.8 billion in total crypto assets, including 5,929,198 ETH and 211 Bitcoin, along with a $180 million equity stake in Beast Industries. Chairman Tom Lee said the company has staked more ETH than any other entity globally.

XPR Network, a layer-1 blockchain, suffered a major exploit tied to proton.swaps after an attacker abused a bug in the platform's withdrawal logic. The function reportedly accepted negative amounts, allowing the attacker to distort internal accounting before pulling out legitimate tokens. The attacker initially drained about 1.56 billion XPR, valued at roughly $4.03 million, then repeated the method across several pools including XUSDC, XMD, METAL, LOAN and various bridged assets. In about 11 minutes from the start of the attack, more than $9 million in liquidity was taken. Onchain data also showed 563 million XPR (about $1.46 million) moving through the LOAN protocol after the attacker borrowed against stolen stablecoins. That brought the total amount of XPR involved to about 2.12 billion, equivalent to roughly 6.5% of circulating supply. The attacker later transferred 764 million XPR (around $1.98 million) and 150,000 METAL (about $195,000) to another account. Network producers subsequently identified the exploit and patched the contract, highlighting how weak input validation can rapidly magnify losses across interconnected liquidity pools. Market impact: XPR selloff pressures sentiment The drain quickly fed into price action. On Sept. 11, XPR traded near $0.00276 before sliding the next day. The selloff drove an intraday low around $0.00242, a drop of about 6.5%. Buyers later lifted the token toward $0.00259, though the rebound remained constrained as XPR stayed below the $0.00271 support level. Momentum indicators reflected the stress: RSI fell to 27.47, indicating oversold conditions and intense selling pressure. Turnover climbed toward $4 million. A more durable recovery would likely require XPR to reclaim $0.00271 and stabilize sentiment. Most affected funds secured Post-exploit flows suggested losses were largely containable. Of the 2.12 billion XPR touched, about 1.80 billion remained in attacker-controlled accounts, while 319.5 million XPR reached external venues. Producers applied a contract patch at 21:32 UTC. At 23:26 UTC, they seized the 1.80 billion XPR and placed it under community control, leaving most of the affected funds potentially recoverable. By Sept. 13, XPR was trading around $0.00261–$0.00262, signaling that selling pressure had eased. With most funds now secured, attention turns to whether XPR Network can rebuild liquidity and restore user confidence. Final take: XPR Network lost about $9 million in the proton.swaps exploit. XPR fell 6.5% before stabilizing, and the majority of impacted XPR was secured, shifting the focus to liquidity recovery and trust.

Chainflip, a cross-chain swap protocol, said on Sept. 13 that an attacker siphoned 736,442.17 USDT from its Tron integration in the early hours of Sept. 12. The incident is the first major security event to cause a direct loss from Chainflip vaults. The protocol has halted operations and expects to remain offline until at least Monday as it finalizes a technical restart plan. Chainflip explained that, on Tron, it parses swap instructions from a memo field attached to transactions, rather than relying on dedicated smart-contract functions used across most other supported chains. The attacker reportedly discovered a method to append their own memo to transactions that had already been signed by Chainflip validators. The system interpreted the added memo as a separate swap, marked it as failed, and triggered a refund, effectively allowing the same deposit to be paid out twice. The issue surfaced after later USDT payouts began failing, prompting an internal investigation. Chainflip said the attacker first executed small test runs, then roughly doubled the size of each subsequent round, repeating the process eight times over about 90 minutes. Based on current findings, 736,442.17 USDT was removed through six unauthorized payouts. A separate user swap of 115,654.41 USDT could not be paid and remains in the vault; Chainflip said it can be processed once the protocol restarts. The firm added that all other funds are unaffected and secure. Chainflip said it believes it can fully compensate impacted users, though it is still evaluating the exact mechanism for making users whole. The team said a fix has been designed, but restarting cleanly with minimal disruption requires additional work. Chainflip also said it has flagged the exploited funds with relevant parties in an effort to support recovery as the proceeds move through crypto markets. A full post-mortem will be published after the restart plan is finalized and operations resume securely. Chainflip added that increasingly sophisticated AI models are reshaping the security landscape and said it plans to step up internal efforts to use such tools to identify vulnerabilities before attackers. The incident comes amid a recent wave of exploits targeting Tron-based protocols.

Cardano (ADA) traded around $0.208 on Sept. 13 after its latest rebound attempt stalled, leaving price pinned near the $0.205 support zone. A bearish flag formation remains the dominant setup, with a decisive break below $0.205 potentially opening the way toward the pattern's downside target near $0.192. ADA has slid from above $0.22 over the past week, though selling pressure is starting to cool. Momentum gauges suggest the bearish impulse is fading, but the chart still needs a reclaim of $0.210 to improve the near-term outlook and set up a run toward resistance around $0.229. Technical setup: $0.205–$0.206 is the line to watch Recent sessions have seen ADA drift within a rising channel following a sharp drop—a structure widely labeled a bearish flag, keeping sellers in control of the broader short-term trend. The $0.205–$0.206 band has been tested repeatedly inside the pattern. A clean move below it would strengthen the breakdown case, with $0.192 as the next notable downside level. On the daily chart, additional support sits near $0.201, where price previously bounced and may be forming a potential double bottom. That pattern still lacks confirmation, and bulls would need a move above $0.229 to gain clearer control of the daily structure. Broader market conditions were moderately supportive during the session, with Bitcoin near $77,300 and Ethereum around $2,530. ADA also posted intraday gains, but remained capped beneath key resistance. Hydra 2.4.1 addresses transaction validation vulnerability Cardano developers released Hydra 2.4.1 after identifying a security weakness in earlier versions of the scaling protocol. The issue could allow a malicious participant within a Hydra Head to submit an invalid transaction that might be included in a confirmed snapshot, creating a risk of stolen funds. Version 2.4.1 updates the validation flow so transactions receive full checks before confirmation. Input Output Global advised users on Hydra 2.3.0 and 2.4.0 to upgrade. Development progress also continued with node version 11.1.1, part of preparations for the Dijkstra hard fork aimed at further performance improvements. The security update has not materially altered ADA's near-term chart picture, which continues to track within the bearish flag as traders watch the lower support band. On-chain activity stays soft despite updates Network activity has weakened across several indicators. Total value locked fell below 300 million ADA, while active addresses dropped to 12,204—the lowest level since Aug. 17. Decentralized exchange activity improved modestly, with daily DEX volume rising from about $1.13 million to $1.65 million, still far below the September high of $7.28 million. Momentum indicators: bearish pressure eases, but key levels remain On the four-hour chart, ADA has held above the recent low near $0.203 after sliding from the $0.229 area. Smaller candles point to slowing sell-side intensity. RSI rebounded to 44.50 and is above its signal line at 43.24. While still below the neutral 50 level, the flattening profile suggests downside momentum is weakening. A move back above $0.210 would be needed to extend the recovery toward the prior range. MACD also indicates the down move is losing steam. The MACD line is near 0.00195 versus the signal line around 0.00216, while the histogram has turned slightly positive at 0.00022. Both lines remain below zero, leaving nearby support around $0.200 in focus if selling pressure returns.

According to ME News, the Zcash community's advisory vote on the NU7 network upgrade is set to end on September 14, as of September 13 (UTC+8). The main proposal would replace periodic halving events with a smooth emission curve. A separate proposal would cut the block interval to 25 seconds from 75 seconds. The changes would not affect ZEC's total supply cap, but would alter the timing of new coin issuance. Even if the proposals gain support, further development and deployment would still be required before any upgrade goes live. ZEC recently climbed to its highest level since 2018, last trading at $1,093.21 and ranking 10th by market capitalization. (Source: ChainCatcher)

ChainThink cited GMGN data dated Sept. 13 showing a broad pullback in meme coins tied to AI-themed equities, after comments from Anthropic CEO Dario Amodei and OpenAI founder Sam Altman pressured sentiment. Amodei said the industry should slow the pace of advancing AI model capabilities, and Altman said he agreed. Among the largest movers, ANTHROPIG fell 44% over the past 24 hours to a $5.4 million market cap and trades against ANTHROPICx1L (Anthropic 1x Long tokenized position). Artificial Inu (AI) slid 27% to $247 million and is paired with NVIDIA stock. MOO dropped 37% to $18 million and is paired with Micron stock. Microduck declined 26% to $7.3 million and is paired with NVIDIA stock. FLYBRAIN shed 23% to $9.6 million and is paired with Google stock. Elsewhere, the suspected AI project UBIK fell 25% to a $28 million market cap. CATGPT sank 22% to $6.7 million and trades against OPENAIx1L (OPENAI 1x Long tokenized position). Amodei said slowing down does not mean stopping model training or technological progress, but allowing enough time to align and safeguard the models.

Voting on Zcash's proposed NU7 network upgrade will run until September 14, according to CryptoSlate. The lead proposal would swap the current halving schedule for a smoother issuance curve. A separate proposal weighs cutting the block interval to 25 seconds from 75 seconds. The changes would not affect ZEC's total supply cap, but would reshape the timing of new coin issuance. The ballot is advisory and the upgrade would still need formal approval before development and rollout can move ahead. ZEC recently hit its highest level since 2018, trading at $1,093.21 and ranking 10th by market capitalization.
