mainnet

DyorSwap officially announced that the so-called "GIWA Mainnet" identified by the team earlier is actually a fake chain set up by scammers. This fake network used the correct GIWA chain ID (9134), making it appear legitimate during the initial verification phase. The team also identified several suspicious messages and individuals within the related community that may be connected to this incident. The announcement stated that significant losses have occurred due to this fraudulent cross-chain bridge.DyorSwap stated that it is taking three immediate actions: first, contacting a professional security team to conduct further on-chain tracking and investigate the involved addresses, transactions, and fund flows; second, preserving all relevant evidence, including chat records, RPC information, cross-chain bridge addresses, and on-chain transactions; third, preparing to use treasury funds to compensate affected users, with eligibility criteria, loss verification processes, compensation scope, and detailed plans to be announced after the investigation and verification processes are completed.DyorSwap emphasized that until further notice, users should not use any unofficial GIWA mainnet RPCs, cross-chain bridges, or contracts, and should not send funds to any related addresses. The official team deeply apologizes to every affected user in this incident and states that subsequent updates will be released as soon as possible.

GIWA official account (@GIWA_by_Upbit) issued a statement clarifying that the project's mainnet has not yet been launched and that RPC has never been online, so there is no risk of any RPC leakage. Users are reminded to do their own research (DYOR) and to be wary of FUD and scam information. It is reported that GIWA is an Ethereum L2 project developed by Dunamu, the parent company of Upbit, based on the OP Stack, aiming to achieve a 1-second block time and be compatible with EVM. It is currently still in the testnet phase.

According to DefiLlama data, the DeFi TVL of Arc, the public chain under Circle, reached 494 million USD on the 10th day after its mainnet launch, with a growth of 44.52% in the past week, ranking first among leading blockchains in growth rate.In terms of DEX trading volume, the network achieved 55 million USD in transactions in the past 24 hours.

The public chain Arc officially announced that Circle's on-chain foreign exchange engine StableFX has now launched on the Arc mainnet. Arc is the public chain launched by Circle, aimed at stablecoins and payment scenarios.The global foreign exchange market has a daily trading volume of nearly 10 trillion USD, most of which still relies on traditional trading hours. StableFX supports round-the-clock settlement, allowing for near-instant or delayed settlement, where both parties can either receive funds simultaneously or not at all to reduce settlement risk. A single contract can trade with multiple vetted counterparties and obtain pricing through a unified RFQ model.

According to data from Dune, the network transaction fees on the sixth day since the launch of Circle's Arc mainnet dropped to approximately $9,218, a decrease of 96.7% compared to the first day of launch.During the same period, the daily transaction fees for Robinhood Chain, Base, Arbitrum, and Sui were approximately $312,000, $139,000, $22,300, and $11,500, respectively.

MultiversX announced that it has confirmed an attacker attempted to exploit atomicity issues at the virtual machine (VM) level of the mainnet, resulting in invalid state changes on the chain. To prevent further impact, the network has currently suspended operations. The engineering team has prepared a fix and is validating it in a shadow fork environment. If the tests are successful, they will coordinate with validation nodes, exchanges, and infrastructure partners to deploy the fix to the mainnet.Meanwhile, the team is evaluating a targeted recovery plan aimed at preserving the finalized transaction history and legitimate user states while only addressing the invalid changes related to this incident. Users do not need to take any action; they just need to wait for notifications regarding the restoration of normal operations. The official reminder advises users not to submit or rebroadcast transactions, and not to recharge or withdraw EGLD and ESDT through exchanges or cross-chain bridges.

The privacy-oriented public chain Midnight is preparing to open smart contract deployment on the mainnet.

MultiversX posted on the X platform that the team is investigating a potential issue detected on the MultiversX mainnet. Their top priority remains to protect users and ensure the network operates securely and reliably.MultiversX stated that further updates will be released within the next 12 hours or as soon as a clear conclusion is reached.

Aptos Labs announced that Confidential APT has been launched on the Aptos mainnet. Balances and transfer amounts are encrypted on-chain, and validators check zero-knowledge proofs to confirm the validity of transfers without viewing the specific amounts.Addresses remain public, and this feature is completely optional, allowing for public verification without public disclosure.

The Zcash development team plans to activate the NU7 mainnet upgrade on November 5, after various organizations and engineering teams have reached a consensus on the upgrade content and expected timeline. Zcash developer Sean Bowe stated that the upgrade will be activated on the testnet on October 6. The team plans to finalize the mainnet upgrade and activation block height after evaluating the performance of the NU7 testnet on October 20.The upgrade will shorten the target block interval from 75 seconds to 25 seconds, disable version 4 transactions, and integrate a network sustainability mechanism. The selected network sustainability mechanism will retain the Zcash halving cycle, with the previously removed supply being reintroduced starting February 2031. NU7 does not introduce a new transaction format, resulting in limited impact on wallets, but full nodes, indexers, and block explorers may need adjustments.

According to monitoring by Ai Yi, about 2 hours after the mainnet launch of Arc, the public chain under Circle, the total amount of USDC in the network has reached 372 million, accounting for approximately 0.05% of the total USDC supply, with the current total number of on-chain addresses being about 176,000.Previously, some users entered Arc across chains at an 80%-100% premium in USDC before the mainnet launch to participate in early Meme coin trading.

The Solana client development team Anza posted on X that Transaction V1 (SIMD-0385) has been launched on the mainnet.This version increases the maximum transaction size from 1,232 bytes to 4,096 bytes, allowing ZK proofs, large multi-signatures, BLS signatures, and previously required multiple transactions for confidential transfers to be included in a single atomic operation. V1 also moves resource requests such as computation unit limits, priority fees, account data loading size, and heap size into the transaction header, rather than submitting them through computation budget instructions.

According to SolanaFloor, Jump Crypto's Firedancer team will stop supporting the Solana transitional validator client Frankendancer after Alpenglow is activated on the Solana mainnet, with the upgrade expected to go live in October with v4.3.The team stated that the decision was made due to the maintenance and security burden, and they will subsequently focus resources on the complete Firedancer client.

The blockchain project Quantus announced the launch of its PoW mainnet using post-quantum cryptography, which incorporates the ML-DSA-65 and ML-DSA-87 digital signature mechanisms. The total supply limit of the native token QTC is 21 million, and PoW mining has been open since the launch.

The core development team of Solana, Anza, posted on platform X stating that the mainnet Beta transaction V1 will begin activation at epoch 1035, expected around September 15 at 1:20 UTC.The ecosystem team indicated that more time is needed to test and integrate V1 support; V1 is currently live on the development network for integration testing. The computational budget in V1 is set through new transaction configuration settings; the computational budget instructions are still usable in traditional transactions and V0 transactions, but will not take effect in V1; application developers should check the impact of related changes on their applications even if they do not plan to send V1 transactions.

Quantus founder and CEO Yuvi Lightman posted on X that the anti-quantum blockchain Quantus mainnet will go live on September 9 (Wednesday). The only way to acquire tokens at the launch is through mining, and liquidity and tradability will be available a few weeks later.The team has merged Immunefi security work into the public code repository and completed all fixes from the audit competition. The chain supports ML-DSA-65 and ML-DSA-87, binding each signature to its context according to FIPS 204 standards, failing and closing multi-signature transactions that cannot be decoded, and strengthening the network stack to resist denial-of-service attacks. The team has completed a full-process drill on the global rehearsal mainnet covering the Americas, Asia, Europe, and Australia, producing signed binaries through an automated pipeline, deploying multi-region bootnodes and dedicated RPC nodes as infrastructure as code, and reducing indexer memory usage from over 90% to about 26%.In addition, Quantus has launched a registration page, completed a website redesign, Keystone hardware wallet supports multiple accounts, and released CLI v2.1.3 and miner v4.0.2. Quantum & Privacy Day will be co-hosted with NEAR in Singapore on October 8, coinciding with Token2049.

Scroll Governance Forum posted that the team will recently apply AI extensively in operations and product development. Previously, core chain operations required over 20 engineers, but now it is completed by fewer dedicated engineers in conjunction with AI agents, while maintaining existing usability and security standards. The team believes that blockchain can provide a trusted coordination layer to define and execute rules, and ZK can help agents interact with credentials, private data, and computations without exposing underlying information.The team is building an interconnected product stack: Compass is an iOS application that can access the large models and functions provided by the Compass API, and includes VPN and eSIM; Compass API is the AI routing infrastructure, connecting over 30 large models; CENO provides a trust layer through ZK, protecting credentials, agent context, and privacy computations; USX is used for payments and settlements; SCR continues to coordinate governance; the Scroll network serves as a trust and coordination layer. CENO has reached out to over 30 potential clients, of which 12 are participating in proof of concept testing.The team plans to gradually transform Scroll from a general public chain into a dedicated network centered around Compass and the AI product stack, with an overall transition expected to take about nine months. According to the current plan, SCR will migrate to the Ethereum mainnet to maintain accessibility and liquidity, with supply and token economics remaining unchanged, and will continue to serve as a governance token. This post is only a progress update, not an official proposal or vote, and further proposals regarding the network transformation and matters requiring DAO approval will be made separately.
