Ethereum News: BitMine Adds ETH, Nillion Plans October Mainnet Launch

Ethereum News: $4.3M Wallet Loss, BitMine Buying and Nillion Roadmap

Ethereum's ecosystem saw a cluster of notable developments in the past day, spanning corporate treasury accumulation, privacy infrastructure, a security incident, prediction market competition, and whale trading activity. 

This roundup of Ethereum news today covers five separate reports: BitMine's continued ETH accumulation, Nillion's roadmap toward an October mainnet launch, a suspected wallet compromise flagged by security firm Specter, prediction market platform Trueo's planned migration to 

Ethereum, and a swing trade from a long-dormant ICO-era wallet. Together, these stories offer a snapshot of how institutions, developers, security researchers, and early holders are engaging with the network this week.

At a Glance

• BitMine now holds 5,983,940 coins(4.9% of total supply) after adding 27,562 coins in a week

• Nillion's Encrypted Markets protocol plans an Ethereum mainnet launch in the first week of October

• Specter reports a suspected private-key compromise linked to losses exceeding $4.3 million across EVM chains, Tron, and Bitcoin

• Prediction market Trueo is migrating from Base to mainnet, prompting comments from Vitalik Buterin

• A 2015 Ethereum ICO whale repurchased 8,630.6 coins after an earlier sale, resulting in a 2,921 coins shortfall

BitMine Adds 27,562 ETH as Holdings Near 6 Million

Bitmine (BMNR), described as the largest Ethereum treasury company, increased its ETH holdings by 27,562 coins over the past week. As of September 20, the company held a total of 5,983,940 coins, equal to roughly 4.9% of Ethereum's circulating supply and about 98% of its stated goal of controlling 5% of total coins. Of that total, 5,067,309 coins is staked, valued at approximately $13.6 billion based on a $2,688 coin price. 

Including cash, securities, and other holdings, the company's overall asset value is reported at approximately $17.1 billion, with $714 million held in cash and securities. Separately, on-chain monitoring account Onchain Lens flagged an additional 12,500 tokens (about $34.6 million) accumulated from Kraken, following a prior withdrawal of 20,000 tokens roughly three weeks earlier. This appears to be independent on-chain tracking rather than part of BitMine's official weekly disclosure.

Nillion Sets October Ethereum Mainnet Launch for Encrypted Markets

Decentralized privacy computing network Nillion has published a seven-phase roadmap for its Encrypted Markets initiative. The first phase, Dusk, went live on the Ethereum Sepolia testnet in August, with the first Covenants-powered application already open for testing. Nillion plans to bring Dusk to the mainnet in the first week of October, introducing condition-gated events and permissionless nodes for developers. 

Later phases are named Darkfall, which extends Covenants to additional EVM chains; Skyglow, which adds cross-chain execution; Nightside, which introduces user-defined conditions; Neon, which brings a dedicated programming language and virtual machine; Aurora, which adds post-quantum hardening; and Moonshine, which focuses on reducing cost and improving performance at scale.

Ethereum Faces Security Alert as Over $4.3 Million in Assets Are Reportedly Stolen

Security monitoring firm Specter reported that a private key belonging to an unidentified victim is suspected to have been compromised, resulting in losses exceeding $4.3 million across EVM chains, Tron, and Bitcoin. According to Specter, the attacker has drained more than 145 Ethereum addresses, most of which held USDC. 

Stolen funds were reportedly converted to ETH, moved across chains, and consolidated with stolen Bitcoin from at least five separate addresses. Specter noted the attacker remained active in transferring wallet assets at the time of reporting, meaning the final stolen total could rise further. Anyone managing significant on-chain assets should treat this as a reminder to review key storage and wallet security practices.

Trueo Plans Ethereum L1 Migration as Prediction Market Competition Expands

Vitalik Buterin commented that a new prediction market contender is set to emerge on layer 1, one focused on decentralization, ethical design, and practical applications of prediction markets as an economic tool. 

This follows an announcement from prediction market platform Trueo that it will migrate from Base to the ETH mainnet. Trueo said its long-term goal is a broadly integrated, fully permissionless prediction market built on immutable core contracts, with near-term priorities including improved market liquidity and upgrades to its oracle and dispute-resolution systems. 

The company stated the move is driven by Ethereum network effects, integration capabilities, and decentralization properties, and is not related to any issue with Base's development. 

Existing Base-based markets will continue trading, settling, and allowing redemptions during the migration window, and TRUE token holders will have the option to migrate to Ethereum over time.

Ethereum ICO Whale Buys Back 8,630 ETH After Earlier Sale

According to blockchain analyst Ember, a wallet that participated in Ethereum's 2015 ICO and originally acquired roughly 38,800 tokens has re-entered the market. 

The address sold 11,552 ETH about six months ago at an average price near $2,027, receiving approximately 23.42 million USDT. In the early hours of September 22, the same wallet spent about 23.726 million USDT to repurchase 8,630.6 ETH at an average price of $2,749. 

Measured in ETH terms, this round-trip trade left the wallet holding roughly 2,921 fewer tokens than before the sale, a position worth approximately $8.03 million at the repurchase price.

Timeline: Major Ethereum Developments

• 2015: ICO whale acquires approximately 38,800 ETH

• 6 months ago: Whale sells 11,552 ETH at roughly $2,027

• August 2026: Nillion's Dusk launches on Ethereum Sepolia

• September 20: BitMine reports 5,983,940 ETH holdings

• September 21: Nillion publishes seven-phase Encrypted Markets roadmap

• September 22: Specter reports suspected $4.3M+ wallet compromise

• September 22: Trueo migration and whale repurchase reported

• First week of October: Nillion targets Dusk mainnet launch

What These Developments Mean for Ethereum's Ecosystem

Taken together, these five stories point to several parallel trends rather than a single narrative. Treasury companies like BitMine continue expanding their ETH exposure toward stated supply targets. 

Developers are building out privacy and prediction market infrastructure directly, reflecting continued confidence in the network's integration capabilities. At the same time, the Specter-reported compromise is a reminder that wallet and key-management risks remain a persistent challenge across chains. 

Large, long-term holders such as the 2015 ICO whale continue to make active trading decisions that can result in gains or losses depending on timing. None of these developments should be read as a signal about where ETH's price is headed next.

Ethereum price today is at $2733.12, up by 2.5% over 24 hours. It recorded about $25.74 billion in trading volume, while its market capitalization stood near $333.63 billion.

Ethereum News Today: What to Watch Next

Several threads from this roundup are worth tracking in the coming weeks. Whether Nillion's Dusk protocol successfully launches on the Ethereum mainnet during the first week of October, as planned. 

Whether BitMine closes the remaining gap toward its 5% token supply target. Whether the Specter-flagged attacker continues moving funds, which could push the reported $4.3 million loss figure higher. 

How Trueo's migration from Base to Ethereum progresses, and whether TRUE holders choose to migrate. And whether the ICO-era whale makes further trades following its recent buyback.

Conclusion

This roundup of Ethereum news today reflects a network with active participation from institutional holders, infrastructure developers, security researchers, and early adopters alike. From BitMine's continued accumulation to Nillion's approaching mainnet launch, a significant security incident under investigation, Trueo's move to Ethereum L1, and a notable whale trade, each story adds a different dimension to the ecosystem's current state. As with any fast-moving on-chain environment, details such as final loss totals, migration timelines, and launch dates may continue to evolve.
