According to an announcement from the Singapore Police Force's official website, the Singapore police have issued a warning stating that since September 10, they have received at least two reports related to tampered Ledger cryptocurrency hardware wallets, with total losses amounting to approximately 3.5 million Singapore dollars. Preliminary investigations indicate that some Ledger hardware wallets purchased at retail stores in Singapore contained malicious hardware components that could steal users' mnemonic phrases or private keys, and transfer assets without the users' knowledge.The police have contacted Ledger, which is reviewing the related cases, and the investigation is ongoing. The police advise users to stop using suspected tampered devices and to generate new mnemonic phrases with unaffected devices, transferring any remaining assets. Zhao Changpeng shared this news on the X platform, reminding Singapore users to be especially cautious.

On October 26, a mining machine running on the FutureBit Apollo Solo solution mined Bitcoin block 973,262, receiving a complete block reward of 3.154 BTC and collecting transaction fees from 2,477 transactions within that block. Multiple block explorers, including mempool.space, marked the discoverer of this block as "FutureBit Apollo Solo," with its coinbase transaction containing text mentioning FutureBit and Apollo.FutureBit stated on X that the Apollo device or Solo Node assembles block templates, allocates work, and submits complete blocks using its built-in solo pool. This is at least the fourth block attributed to FutureBit Apollo Solo, with the previous three being 867,760, 881,423, and 888,737. FutureBit designs Apollo hardware for users who wish to run a full Bitcoin node and mine independently at home, with the latest model, Apollo III, achieving a maximum hash rate of 18 TH/s in turbo mode and integrating a full node.Solo mining is often referred to as "lottery-style mining" due to the extremely low probability of winning relative to block rewards. Against the backdrop of the Bitcoin network's hash rate recently being around 1,070--1,087 EH/s, the expected time for home devices with 10--18 TH/s to mine a block is still measured in centuries at current difficulty levels, but verified successful cases of solo mining continue to appear on-chain. Additionally, the next day, another miner successfully mined a solo block through CKPool Solo.

According to CoinDesk, Polymarket has launched five-minute cryptocurrency price prediction contracts on its regulated U.S. platform.

According to Bloomberg, the prediction market platform Polymarket is investigating a series of timely and profitable trades that emerged during this week's Israeli elections. According to Bloomberg's analysis, shortly before the voting ended on Tuesday, hundreds of new accounts concentrated their predictions, believing that Benjamin Netanyahu and his Likud party would perform better than their competitors.After some exit polls indicated that Netanyahu's camp won more seats than earlier reports suggested, these trades quickly turned profitable, with some accounts cashing out over $100,000. This is the latest case in the prediction market that has raised concerns about insider trading, as Polymarket has previously faced extensive scrutiny from regulators and public opinion for its accurate predictions related to sports, the U.S. elections, and geopolitical events.

Polygon Labs announced that it has integrated Solana into its Open Money Stack payment platform, allowing the network's enterprise clients to connect their dollar bank accounts directly to the global payment network through a single API framework. The platform supports enterprises in depositing funds from bank accounts, transferring funds across chains, and making payments to recipients, while also providing functionalities such as customer accounts and wallets, currency exchange, and routing payments to supported bank accounts, debit cards, cash services, and cryptocurrency wallets.Kira is one of the first clients to use the Solana integration, helping clients convert between dollars and stablecoins, send payments through banking channels, and pay overseas suppliers. Kira's CEO Edrizio De La Cruz stated that the company has been using Solana to transfer stablecoins, and collaborating with Polygon allows these transfers to be converted into dollars in their bank accounts when clients need to pay suppliers. Open Money Stack simultaneously connects Polygon, Ethereum, and TRON, which was integrated earlier this month.This integration occurred after Solana activated the Alpenglow consensus upgrade a week ago, which reduced the final confirmation time for transactions from approximately 12.8 seconds to 150 milliseconds. According to data from The Block, the total supply of dollar stablecoins has approached $290 billion, with USDT exceeding $182 billion and USDC nearing $76 billion. Vibhu Norby, Chief Product Officer of the Solana Foundation, stated that the volume of stablecoin transactions processed by Solana in 2026 has exceeded $5.5 trillion. Earlier this month, Polygon also completed the acquisition of Coinme, obtaining money transmission licenses and exemptions covering 48 states in the United States.

According to Bloomberg, Sarah Court, the chair of the Australian Securities and Investments Commission (ASIC), stated at a parliamentary hearing that the agency has not received any applications submitted by prediction market operators. Prediction market platforms like Polymarket may face strict regulation in Australia, and any application for an operating license will also undergo rigorous scrutiny.Sarah Court pointed out that the trading mechanisms of prediction markets are similar to the binary options that have been banned in Australia, characterized by a win-or-lose outcome, and the trading subjects are often unrelated to investment or financial markets. Although Australian users can directly access relevant overseas platforms, they are not protected by local financial regulations, making it difficult to obtain dispute resolution and customer fund protection measures.
