mainnet

Harmony has released two proposals to comprehensively shut down the mainnet launched in 2019, migrate the native token ONE to Ethereum, and shift towards an AI video "mashup economy" business. The team stated that the threats posed by national-level attackers and AI entities are the reasons for proposing the network shutdown plan.The migration plan proposes to take a snapshot of user wallets, staking delegations, validator rewards, smart contracts, and tokens within centralized exchanges at the last block of the network, airdropping new ONE to the same wallet addresses on Ethereum, with holders not needing to actively claim; delegated stakes and unclaimed rewards will be airdropped to their respective governance vaults. The total supply of ONE and the issuance rate will remain unchanged, with newly issued tokens intended for the new business and feedback from governors being considered.Multi-signature wallets, liquidity pools, and on-chain applications cannot be migrated. The team urges users to exit all smart contracts by September 10, 2026, and plans to publicly disclose token contracts, snapshot calculations, and airdrop scripts for auditing. Validators can stop running nodes starting from September 10 at 22:00 Beijing time. The team plans to compensate for the difference in issuance rewards between node shutdown and the final block of the network, establishing a one-time compensation pool of $1.372 million, to be paid in four quarters to validators and their delegators who timely shut down, sign agreements, retain stakes, and serve as governors of the new project.The new business will open up prompts and materials for users to create secondary content, with AI entities expanding video stories, and will recruit operators responsible for video generation, distribution, and content review. Harmony plans to subsidize GPU hardware in the first year and promote demand for video generation, with operators required to stake tokens to earn rewards based on service online time. The team plans to help operators generate up to $1 million in total revenue in the first year, provided they meet staking and online rate requirements; promoters can initially earn a 30% ongoing commission from each $10 monthly subscription they recommend. Both proposals are non-binding and the plans may still be adjusted.

HyperliquidNews posted on the X platform that the HyperCore manual lending feature has been launched on the mainnet.

Anza stated that the reduction in Solana token rent has gone live on the mainnet Beta, and proposal SIMD-0437 Step 1 has been activated at epoch 1028.This step reduces the required lamports per byte from 6960 to 6333; subsequent functionality gates will be activated after checking the growth status at the current rent level, ultimately reducing to 696 gradually.

OpenSea will add support on the first day of the Arc mainnet launch (September 16).

AEGIS X (XDAO) announced that it will officially launch its mainnet tomorrow (September 3), and the project will fully enter the ecological operation and global market expansion phase.Previously, the AEGIS X Genesis Reserve Council's global co-construction phase has been completed, with a cumulative co-construction scale reaching 31,656,800 USD.AEGIS X uses USD1 as the core value settlement asset, building an ecosystem around USD1 × AI × DeFi, covering application scenarios such as stablecoin liquidity, on-chain payments, DAO collaborative governance, and AI Agent, promoting more on-chain applications and users to enter the USD1 ecosystem.

Fogo's official announcement states that the Fogo mainnet has been restarted and is operating normally. A total of 400 million FOGO tokens were stolen in this incident, of which 237 million have been recovered and permanently removed from the total supply.The official statement indicates that they are working with centralized exchanges and law enforcement to continue recovering the remaining affected assets. The investigation is still ongoing, and further information will be released through this official channel; please rely solely on updates from this channel.

The first on-chain game launched by FUNVERSE, FUN LONGINUS, will officially go live on the Anubis Chain mainnet on September 1, 2026, at 10:00 UTC (UTC+8 18:00). FUN LONGINUS originates from a hackathon and is an Eastern martial arts chain game designed for the Anubis GameFi ecosystem. It constructs on-chain gameplay around martial arts elements such as the Jianghu, arena, mentorship, Jiazi salary, leader's order, and Huaze artifacts, and is structured competitively based on the twenty-four solar terms.Each match features 24 different addresses participating together, with each player entering the arena using fLGNS. The execution of the match, determination of results, and final settlement are all completed by smart contracts, ultimately producing one leader. Match records, reward distribution, mentorship relationships, and players' Jianghu resumes are all stored on-chain. FUN LONGINUS completed the collective forging of heroes on August 18, 2026, and based on the market price at the time of publication, this collective forging is valued at over 1.4 million USD. The launch of the mainnet marks the game's transition from the hackathon prototype, public testing, and collective forging phase to the official on-chain game operation phase.

According to The Defiant, the Fogo mainnet has stopped producing blocks for about 46 hours since Saturday afternoon due to an attack on the Fogo Foundation, resulting in 4 million FOGO tokens (approximately 10.3% of the circulating supply) being transferred to the attacker's address. The foundation initially stated that the chain itself was unaffected, but 15 hours later, the network was actively paused, and plans were made to restrict the related addresses through an upgrade. Currently, the Fogo official explorer shows the last block as 718,525,971, and the RPC endpoint returns a 502 error, while the on-chain TVL tracked by DefiLlama has been frozen at $987,000 for three consecutive days.This downtime is attributed to Fogo's validator design: the chain is managed by a council of 7 voting validators, with the foundation staking evenly among 7 operators, allowing for coordination to pause and implement a client-level address blacklist within minutes. On the exchange side, both KuCoin and Gate have disabled FOGO deposits and withdrawals but retained trading, with a 24-hour spot trading volume of approximately $2.3 million. Meanwhile, a Twitter account impersonating the Fogo Foundation, @FcgoFNDN, posted a false compensation voting link, and Fogo officials reminded users to rely only on information from official channels.Fogo is the second network to actively pause over the weekend, following Cronos, which rolled back its state due to an attack on the Tectonic lending protocol. Fogo raised approximately $7 million by selling 2% of its supply through Binance before launching its mainnet in January, with a valuation of $350 million. The foundation has not yet disclosed details of the attack, compensation plans, or a restart timeline.

According to the Ontology blog, its core development team discovered potential security vulnerabilities during routine security checks. Due to a high emphasis on the security and integrity of the mainnet, Ontology has immediately suspended block production on the Ontology mainnet to allow the technical team and validators to conduct a comprehensive security review of the network and related components. Ontology stated that no security incidents have been confirmed at this time, and there are no indications that user assets have been lost or stolen. ONT, ONG, and other on-chain assets are currently assessed to be unaffected; this suspension is a preventive security measure rather than a response to confirmed asset losses or ongoing attacks.During the review period, block production will remain suspended, and on-chain transactions cannot be processed. Users do not need to transfer or take any action regarding their ONT, ONG, and other on-chain assets, but should avoid conducting time-sensitive on-chain transactions until the network officially confirms its restoration. The duration of the suspension has not yet been determined, and the team will prioritize the comprehensiveness of the security review over speed; block production will not resume until the network has been thoroughly assessed and confirmed to be secure. The Ontology team is collaborating with validators and ecosystem partners to address this matter and will update progress through official channels, with a separate announcement to be made before and after the network restoration.

SVM public chain Fogo officially announced that the Fogo mainnet has been temporarily shut down as a precautionary measure due to the detection of unauthorized activity in the past hour.The shutdown aims to prevent further transfer of affected assets. During the downtime, the network will be upgraded to restrict addresses related to the incident. Fogo stated that further updates will be shared after confirming more information and urged users to rely solely on this official channel for updates.

Jeremy Allaire posted on the X platform that StableFX will soon launch on the Arc mainnet. Previously, StableFX had launched on the Arc public testnet.StableFX is an institutional-grade stablecoin forex engine that covers local currency stablecoins in major and emerging markets, supporting near-instant, 24/7 on-demand settlement, using a PvP mechanism, which means funds are either credited to both parties simultaneously or not at all, to reduce capital occupation, and it can connect multiple vetted counterparties through a single access point.

The Supernova upgrade of MultiversX decouples consensus from execution, allowing the network to reach consensus on blocks before processing transactions. Before the upgrade, block production followed a sequential model: proposers selected transactions, executed them locally, and submitted blocks containing the results, while validators had to re-execute the same transactions before voting, making execution part of the consensus critical path. Supernova changes this order: proposers select transactions and directly propose blocks without prior execution; validators can immediately vote once they confirm the proposal complies with protocol rules, while execution occurs asynchronously in the background, with execution results typically referenced and notarized in the next block header, lagging consensus by about one block (approximately 600 milliseconds).To address the validity verification issues brought by decoupling, Supernova introduces a virtual memory pool state that tracks pending nonces, expected balance consumption, and transactions that have been proposed but whose execution results have not yet reached consensus, providing proposers with a forward-looking account view. Meanwhile, the Execution-Result Inclusion Estimator (EIE) limits the number of execution results that can be referenced in a block based on the capacity that the minimum specification node can safely handle; an automatic backpressure mechanism reduces block capacity when execution lags. Supernova has been producing 600-millisecond blocks on the testnet and devnet since August 20, with the mainnet expected to activate on September 10, 2026.

Hyperliquid co-founder Jeff Yan stated that the manual borrowing feature of HyperCore has been launched on the testnet. Currently, all borrowing functions on the mainnet are still limited to the portfolio margin model.The HyperEVM smart contracts can now access HyperCore's lending features through CoreWriter and read-only precompiled contracts.

The ECX plan will be launched in three phases. The Alpha phase is expected to go live near Bitcoin block height 963648, the Beta phase is scheduled for September 20 at block height 967680, and the permanent mainnet is planned to launch on October 31 at block height 973728. The project is driven by Paul Sztorc, founder and head of Layertwo Labs, and developer of Drivechains and BIP-300/301.ECX will replicate the transaction ledger of Bitcoin's designated snapshot and allocate ECX to the majority of Bitcoin holders on a 1:1 basis on the new network. Users who control their private keys through self-custody wallets at the time of the snapshot will directly receive the corresponding assets, while users of exchanges and other custodial institutions will need to wait for the relevant platforms to decide whether to support the fork and distribute ECX. The original BTC will not be exchanged, locked, or transferred. ECX plans to initially launch seven dedicated sidechains: Thunder, Zside, Bitnames, Bitassets, Photon, Truthcoin, and Coinshift. Of the approximately 1.1 million early Bitcoins associated with Satoshi Nakamoto, about 600,000 ECX will continue to be allocated to these addresses, and approximately 500,000 ECX will be converted through special transactions for early investors and development funds, but this will not affect the BTC on the Bitcoin network.

Stablecoin issuer Circle announced that its blockchain network Arc mainnet will officially launch on September 16. Arc is positioned as a financial infrastructure for the global financial market, aimed at supporting related applications and settlement scenarios.According to reports, the Arc testnet has processed over 500 million transactions to date, with nearly 3 million wallet addresses participating. Additionally, more than 100 partners have remained active on the private mainnet. The initial validator group is expected to participate in network operations alongside Circle.Circle stated that it will continue to promote the construction and ecological expansion of Arc as the underlying infrastructure for the financial market.

Solana developer Brennan Watt announced on the X platform that the Solana mainnet has activated the first slot time reduction, with the target decreasing from the current 400 milliseconds to 350 milliseconds, which will officially take effect in the 1020th Epoch.Watt pointed out that some SDK constants (such as DEFAULT_MS_PER_SLOT) have not yet been updated to the new values and will be pushed in subsequent versions. The transition period may affect applications that rely on SDK constants matching the mainnet reality, and developers are advised to manually determine whether the functionality is enabled based on Epoch boundaries when it takes effect. Watt explained that the long-term plan is to put these parameters on-chain for client queries, but currently, to launch the reduction feature as soon as possible, this transition period must be endured.

Uniswap announced that it will complete the deployment when the September Arc mainnet officially goes live, providing developers with deep on-chain liquidity infrastructure to support the construction of DeFi applications such as lending, structured products, LP strategies, and token issuance. Arc is a public chain under Circle, using USDC as the Gas token, and features sub-second deterministic finality.
