LNbits tells operators to shut down servers after wave of attacks

📋 Summary
LNbits has asked operators to shut down their servers immediately after detecting a wave of attacks. The team is preparing security patches, while the extent of the incident and the exploited vector have yet to be detailed.

On Sunday (8), LNbits recommended that all operators immediately shut down their servers following a wave of attacks against platform instances. The alert is aimed primarily at those hosting the software to create wallets and accounts on the Bitcoin Lightning Network.

The team said it needs to release several security patches and advised keeping services offline until the fixes are available. So far, the project has not published a technical report identifying the exploited vector, affected versions, or total funds compromised.

Alert affects operators hosting Lightning wallets

LNbits is an open-source system installed on top of a Lightning node. It allows a single infrastructure to provide multiple accounts, wallets, payment terminals, and integrations without requiring a separate channel for each user. As a result, a vulnerability in an instance can affect not only the administrator but also people and services holding balances in it.

The emergency notice was posted by the project's official account on X and reported by specialized news outlets. An operator identified as KevinR4 reported losing 2,285,545 satoshis in about five hours after attackers allegedly created accounts and made withdrawals. This figure refers to one instance's report and is not a consolidated estimate of the incident.

It is still unclear whether the attacks depend on a specific configuration, an extension, or a flaw in the software's core.

Square brings Bitcoin to more than 4 million merchants

Square is expected to complete the expansion of Bitcoin payments to eligible merchants in its U.S. network by November 10. Purchases use the Lightning Network, can be settled in BTC or dollars, and will have zero fees through the end of 2026.

BNB Chain strengthens warning against risky dApps and contracts

📋 Summary
BNB Chain has once again promoted Red Alarm, a tool that flags potentially risky dApps and contracts before users connect a wallet. The feature helps with screening, but it does not replace users’ own analysis or guarantee that projects not on the list are safe.

This weekend, BNB Chain reiterated its recommendation to use Red Alarm, a DappBay security service that brings together decentralized applications and contracts classified as potentially risky. The tool lets users consult a list of alerts and check addresses before signing transactions or granting permissions through a wallet.

The move comes at a time of heightened attention to security across the ecosystem. In recent days, the network itself had to advise operators to fix a vulnerability in the Reth client that affected EVM-compatible networks. Red Alarm, however, serves a different audience: everyday users who need to evaluate an application before moving their assets.

Keeping users safe takes ongoing work across crypto. BNB Chain’s Red Alarm flags potentially high-risk dApps and contracts.— BNB Chain (@BNBCHAIN) November 7, 2026

Red Alarm is not a new launch

Although some posts have presented the announcement as a launch, Red Alarm has existed since 2022. BNB Chain’s recent message is a renewed promotion of the service, not the debut of a product. This distinction matters because the tool has already built up a usage history and maintains regularly updated lists of projects and contracts assessed by the system.

In the DappBay interface, users can filter alerts by network, category, reason for the risk, and date added. The signals shown include suspected scams, excessive concentration of control, and websites that have stopped working. Users can also enter an address into the scanner to get an indicative assessment before interacting with it.

Aave buys Avon to advance fixed-rate lending

📋 Summary
Aave Labs has acquired Avon’s team and technology to develop on-chain lending with fixed and variable rates. The deal includes protocols, an on-chain order book, and three professionals, but no price, timeline, or launch market has been announced yet.

Aave Labs has acquired the team and technology behind Avon, a project specializing in on-chain lending with fixed and variable rates. The deal brings an order book built specifically for decentralized credit into the Aave ecosystem and bolsters the protocol’s effort to offer more predictable borrowing costs.
The announcement was made by Aave Labs on its official blog on Friday (6). The financial terms were not disclosed. For now, there is also no launch date, chosen blockchain, or governance proposal detailing how the technology will be incorporated into Aave markets.
What Aave bought from Avon
The package includes Avon’s fixed- and floating-rate lending protocols, its on-chain order book, domains, and related assets. Prince Sinha, Avon’s founder, and Ayush Kaul are joining the Aave Labs engineering team. Omar el-Ashaal is joining the business development team.
According to Aave, the team will work on network and product layers, focusing on new forms of credit. The company says its network has more than US$ 33 billion in deposits and more than US$ 13 billion in active loans.
The acquisition appears to focus on technology and expertise, rather than liquidity alone. Avon developed isolated-risk structures and a mechanism that matches credit offers and requests under set terms. This approach differs from the more common model in DeFi protocols, where rates change based on pool utilization.

Crypto ETFs lose US$ 537 million in one day

📋 Summary
Spot Bitcoin, Ethereum, Solana, and Hyperliquid ETFs recorded combined net outflows of US$ 537.4 million on Friday. The move was driven by BlackRock’s IBIT, while Bitcoin remained near US$ 76 thousand.

Spot cryptocurrency exchange-traded funds (ETFs) ended Friday, November 6, with net outflows of US$ 537.4 million. The result was driven by Bitcoin products, which lost US$ 411.9 million, and Ethereum funds, which saw outflows of US$ 93.3 million.

Data from DefiLlama’s ETF dashboard, compiled from information provided by Farside Investors, also show redemptions of US$ 24.2 million from Solana ETFs and US$ 8 million from Hyperliquid funds. The outflows follow a week of strong risk aversion, marked by a correction in cryptocurrencies and volatility in U.S. technology stocks.

BlackRock accounts for the largest outflows

BlackRock’s IBIT Bitcoin ETF alone accounted for US$ 403 million in outflows during the session. This was partially offset by Fidelity’s FBTC, which received US$ 42.8 million. Among the other Bitcoin funds, Bitwise’s BITB lost US$ 20.5 million; Ark Invest and 21Shares’ ARKB saw redemptions of US$ 20.1 million; and Grayscale’s GBTC recorded outflows of US$ 11.1 million.

Farside Investors says its figures are updated as issuers report share creations and redemptions. As a result, intraday totals may change until all funds have completed their reporting.

In Ethereum, BlackRock’s ETHA led outflows with US$ 90.8 million. Pressure on the funds reflects a market that remains fragile: Bitcoin was trading near US$ 76 thousand on Saturday morning, while Ether remained around US$ 2.24 thousand.

Circle freezes US$ 1,1 billion in USDC after Binance attack

📋 Summary
Circle froze around US$ 1,1 billion in USDC associated with the attack involving more than US$ 6 billion against Binance. The issuer says it acted in coordination with authorities and advocates for faster global mechanisms to curb the laundering of stolen assets without trampling due process.

Circle froze approximately US$ 1,1 billion in USDC associated with the attack against Binance, according to a statement published by the stablecoin issuer itself this Thursday (5). The measure was taken in coordination with authorities and represents one of the largest interventions disclosed by a stablecoin company following an attack on the crypto sector.

The incident involving the world's largest exchange involved more than US$ 6 billion in digital assets. Circle said the investigation is ongoing and cited the FBI's attribution of the case to actors linked to North Korea. The company, however, avoided treating that assessment as a definitive conclusion and focused its message on the need for an international response capable of keeping pace with the speed of on-chain transactions.

Freezing prevents transfers, but does not determine what happens next

In its official statement, Circle explained that the freeze prevents USDC from entering or leaving the addresses affected by the measure. The company emphasized that it does not decide who owns the funds, whether a crime occurred, or whether the assets should be confiscated. Those decisions are up to the authorities and the courts.

The distinction is important because centralized stablecoin contracts allow balances at specific addresses to be blocked. This feature creates an opportunity to stop the circulation of stolen funds, but it also concentrates operational power in the issuer. In Circle's case, the company says it acts only in response to valid legal process and keeps the stages of freezing, investigation, and any eventual permanent forfeiture of the assets separate.

BNB Chain boosts validator throughput by 40% with BSC-Reth

📋 Summary
BNB Chain says the latest BSC-Reth configuration increased validator throughput by around 40% in internal tests. The Rust client is expected to be adopted by validators by the end of 2026, improving performance and software diversity on the network.

This Friday (6), BNB Chain shared new results for BSC-Reth, an execution client written in Rust and adapted to the high-load conditions of BNB Smart Chain. According to the team, the configuration based on Reth 2.5.1 recorded approximately 40% higher throughput than the previous version, which used TrieDB.

The improvement comes from internal tests, not independent measurements in production. Even so, the result is significant because the network plans to begin migrating validators to BSC-Reth by the end of 2026. In practice, the project aims to process blocks more efficiently without relying solely on the Geth-based client historically used by BSC.

Why BSC needs a faster client

According to the technical report published by BNB Chain, BSC combines three characteristics that put pressure on node infrastructure: a 6.6 TB snapshot, an observed average of 246.7 transactions per second over a one-hour window, and just 0.45 seconds between blocks. In the comparison presented by the team, Ethereum had a 1.6 TB snapshot, 30.81 transactions per second, and 12-second block times.

This profile reduces the time available to execute transactions, calculate the state root, and persist data before the next block. The first stage of BSC-Reth had already reduced p95 block insertion latency by 34.9% and execution latency by 35.5% compared with BSC-Geth. However, validation was still 23.8% slower, indicating a bottleneck in calculating and preparing the state.

The team then incorporated features from versions 2.2.1 and 2.5.

Bitcoin falls to US$ 75.6 thousand as US$ 1.25 billion is liquidated

📋 Summary
Bitcoin fell 6% to US$ 75.6 thousand as the correction in technology stocks spilled over into the crypto market. Liquidations exceeded US$ 1.25 billion in 24 hours, with long positions accounting for nearly 89% of the losses.

Bitcoin fell to around US$ 75.6 thousand on Friday morning (6), wiping out its recovery above US$ 80 thousand following the United States midterm elections. The move came amid strong risk aversion in US stock markets and brought liquidations in the crypto market to US$ 1.25 billion in 24 hours.

According to CoinGecko data collected at 6:00 UTC, BTC was down 6% on the day, at US$ 75.649, after fluctuating between US$ 75.229 and US$ 80.721. The decline comes just two days after the asset returned to around US$ 78 thousand following the Democrats’ victory in the US, showing that the positive reaction was short-lived.

Liquidations hit long positions hardest

Leverage intensified the correction. CoinGlass data shows that 239,119 traders had their positions forcibly closed over a 24-hour period. Of the US$ 1.25 billion liquidated, US$ 1.11 billion came from long bets, equivalent to 88.6% of the total.

Bitcoin led losses in derivatives, with US$ 329.6 million in liquidations. Ethereum followed, with US$ 210.3 million. The largest individual order closed was a US$ 10.94 million long position in Binance’s ETH/USDT pair.

Liquidation occurs when an exchange automatically closes a leveraged trade because the deposited collateral no longer covers the loss. During rapid market moves, these forced sales can put further pressure on prices and trigger additional liquidations in a chain reaction. The episode recalls other waves of deleveraging, such as when Bitcoin fell below US$ 62 thousand in a billion-dollar liquidation event.
