According to the official announcement, Binance has announced that due to its partner brokerage's system upgrade, stock trading on the Binance platform will be temporarily suspended.During this period, users will not be able to place stock trades. The system upgrade window is from October 3, 2026, 19:00 to 20:00.

The Core Lightning team, which develops the open-source Bitcoin Lightning Network node software, has issued an urgent alert stating that reports indicate attackers are targeting nodes that have not installed patches, urging operators still running old versions to upgrade immediately. The team stated: "Emergency security update: If you are using version 26.06.7 or earlier, please upgrade to the latest release as soon as possible."Prior to this, Core Lightning began investigating a potential issue that could affect its experimental features and, in turn, impact user funds on September 16, and approximately six days later, version 26.06.8 was released. This update not only fixed several defects but also provided patches for security vulnerabilities reported responsibly by multiple parties, thanking the Bitcoin Red Team and 12 other individuals and organizations in the release notes, while also acknowledging anonymous reporters.According to the changelog, this round of fixes covers a bug that could cause sender nodes to crash, requests that could exhaust REST interface memory, and a vulnerability that could result in user funds facing confiscation losses when closing payment channels. To provide operators with ample upgrade windows and prevent attackers from taking advantage of reverse engineering and exploitation, this version intentionally obscured some testing content. Additionally, in August of this year, the project initiated a collaborative fixing process after reviewing a large number of AI-generated general vulnerability disclosure reports, and two days later released version 26.06.7 to close confirmed vulnerabilities.

EIP-8363 co-sponsor Jérôme de Tychey announced the withdrawal of the application to include the proposal in the Hegotá hard fork, and the discussion on the related issuance policy will shift to an independent topic.

According to The Block, Base has completed its third mainnet upgrade, Cobalt. The core of this upgrade is the Validity Transactions conditional transaction feature, allowing users to submit transactions with conditions that must be met before they are packaged on-chain; if the conditions are not met, the transaction will never be included.Base stated that this API is part of a neutral infrastructure, allowing advanced traders to keep their submissions confidential before they are finalized.Cobalt also enhances the B20 token standard launched with the Beryl upgrade in June, adding three new features. Composite Policies allow asset issuers to combine existing whitelists and blacklists using "or" and "and" logic, without the need to duplicate lists or maintain off-chain synchronization.The Schedule Multiplier upgrade aligns with the ERC-8056 standard, supporting issuers in changing the display method of asset balances, which can be used in scenarios such as stock splits.Base also revealed plans to shorten block time from 2 seconds to 200 milliseconds in the coming months, implement native smart accounts at the protocol layer, support Gas payment and transaction batching, and introduce some EVM improvements from the Ethereum Glamsterdam upgrade.

Base has completed the Cobalt upgrade, adding conditional trading and issuer control tools for tokenized assets. This upgrade expands the B20 token standard, allowing issuers to set multiple compliance checks for the same asset, including identity verification, accredited investor status, and sanctions list screening.Issuers can pre-set adjustments for corporate actions such as stock splits, updating the number of shares displayed in wallets and applications without issuing new tokens, burning tokens, or changing the underlying balance. Issuers can also authorize administrators to transfer tokens without the approval of holders and attach public explanations; Base cannot initiate such transfers.Cobalt introduces Validity Transactions, allowing users to set on-chain conditions before submitting transactions, for example, allowing exchanges only if the asset reaches a target price before a specified block deadline. Such transactions can remain private before being included in a block. Base enabled B20 as the native standard for stablecoins and homogenized tokens representing tokenized real-world assets on July 8; Coinbase issued B20 tokens representing stocks of Apple, Nvidia, Meta, and Alphabet on Base on August 25.

Aave posted on platform X stating: Multiple user experience optimizations have been made for Aave App, Aave Pro, and Aave V3, and they thank the community for their feedback.Aave also launched the Ghost Pass benefit, allowing users to publish their high scores and receive a Ghost Pass.

The Ethereum Foundation announced that the Ethereum network upgrade Glamsterdam will be activated on the Sepolia testnet on October 6 at 21:53:36 Beijing time, corresponding to epoch 353024 and slot 11296768. The activation date for Hoodi and the mainnet has not yet been determined.Glamsterdam combines the execution layer Amsterdam upgrade and the consensus layer Gloas upgrade. Key changes include the embedded proposer-builder separation and block-level access lists to enhance L1 throughput, as well as adjustments to gas billing to better reflect the costs of execution and state growth. Node operators must update their execution layer and consensus layer clients before activation. Contracts relying on fixed gas assumptions may need to be modified.

According to the official announcement from Binance, Binance will suspend deposits and withdrawals of tokens on the Base network starting from September 30, 2026, at 17:00 (UTC) to support the network upgrade and hard fork. The hard fork is expected to take place on the same day at 18:00 (UTC).During this period, trading functions will not be affected, and Binance will handle all technical matters. Deposits and withdrawals will automatically resume once the network stabilizes, without the need for further announcements.

The co-founder of the on-chain perpetual contract platform Hyperliquid, Jeff, stated that after the next network upgrade, HIP-4 will increase the deployment limits. The maximum number of active HIP-4 results that a single deployer can run simultaneously will increase from 100 to 200, and the maximum number of results that a single deployer can deploy daily will also increase from 500 to 1000.Jeff added that this adjustment was made based on feedback from the community Builders. In addition, the funding rate cap will also be adjusted from 4% per hour to 0.5% per hour in the next upgrade.

According to CoinDesk, the Solana consensus upgrade Alpenglow has completed the switch to Testnet and Devnet on September 24 and 25, respectively, and is currently running on the two major public test networks, allowing application teams to test compatibility before launching on the mainnet. Alpenglow aims to reduce the final confirmation time from about 12.8 seconds to approximately 150 milliseconds by allowing validators to exchange votes directly instead of writing votes as transactions into blocks, enabling consensus to be reached within one to two rounds of voting.The Solana Foundation reminds that the transaction statistics containing validator votes may decrease after the upgrade, but user payments and transaction volume may not necessarily decline; applications that simply send transactions and read account balances do not need to migrate. The 150 milliseconds is a simulated target and has not yet been validated in a real mainnet environment, and wallet processing and exchange deposit confirmations may still increase waiting times. The exact date for the mainnet launch has not yet been announced.

The Solana core consensus upgrade Alpenglow has officially entered the second public test network, and the transaction settlement delay is expected to be reduced from approximately 13 seconds to 150 milliseconds.

The U.S. Securities and Exchange Commission's Division of Corporation Finance updated its frequently asked questions document on cryptocurrency assets on Friday, clarifying that token buybacks, network upgrades, and marketing promotions do not automatically make cryptocurrency assets securities. The division stated that announcing a buyback plan for an already functioning cryptocurrency network does not, by itself, make the associated tokens constitute an investment contract; however, for networks that are not yet operational, if the issuer promotes the buyback as a source of returns for holders, this conclusion may not necessarily apply.Regarding the ongoing development issues of cryptocurrency projects after their launch, the document pointed out that once a cryptocurrency system is operational, services used to protect, maintain, improve, or enhance that system and its functions, or to promote network effects, do not fall under the managerial efforts referred to in the Howey test. The existing uses of marketing networks generally do not create profit expectations, and statements regarding future functionalities are similarly true, provided that profit potential is not promoted. The document reiterated that specific judgments still heavily depend on the actual circumstances of each case.This document is based on the interpretive guidance issued by the SEC in March of this year regarding the application of securities laws to cryptocurrency assets, released just weeks after the Clarity Act failed to advance in the Senate, with regulators continuing to operate under existing laws. Additionally, the U.S. Commodity Futures Trading Commission updated its cryptocurrency FAQs on Thursday, stating that futures companies and clearinghouses may invest customer funds in tokenized versions of previously permitted assets, provided that investment and custody requirements are met; regulated companies may use blockchain for record-keeping but must be able to provide relevant records when the blockchain or its block explorer is not operational.

B.AI announced a major upgrade to its Responses API, which is now fully compatible with upstream standard protocols. Existing models on the platform can be uniformly called through the /v1/responses interface as long as they support the Responses API.At the same time, when B.AI adds new models from integrated vendors in the future, developers will not need additional configuration to automatically and seamlessly integrate them into the Codex client. In this upgrade, the official API full set group adds support for MiMo, Qwen, and Hunyuan series models, while the Mix and OL Station optional service provider group adds support for OpenAI, Gemini, and Grok series models.Developers only need to complete the minimal configuration of the API Key and Base URL to integrate the capabilities of various models into their daily workflows.

The privacy blockchain project Zcash plans to implement the NU7 upgrade, which will stop accepting the fourth version of transactions that spend funds from the Sprout pool after the upgrade. If ZEC is not transferred out before the upgrade, holders may lose the ability to spend the related funds. This proposal will not destroy the Sprout pool funds, and access may be restored in the future, but the proposal warns that funds left in the pool may also become permanently unspendable.Zcash co-founder Zooko Wilcox has forwarded the relevant reminder. The NU7 upgrade is scheduled to activate on the testnet on October 6, and Zcash expects to decide on October 20 whether to activate it on the mainnet as planned on November 5. The upgrade will also reduce the target block time from 75 seconds to 25 seconds and maintain the network halving cycle.

The PermissionDelegationV1_1 upgrade of the XRP Ledger entered a 14-day activation countdown on September 21, having received support from 29 of the 35 trusted validator nodes. If the support rate remains above 80% during this period, the upgrade could officially activate as early as October 5 at 11:18 UTC; at least 28 validator nodes must continue to support it, or the countdown will reset.This feature allows accounts to split permissions by role. For example, a stablecoin issuer can allow a connected compliance system to approve customer accounts holding its tokens while keeping the keys with full control offline; operational accounts can gain payment permissions but cannot change keys or delegate authority to others. Each trustee can have up to 10 permissions, and the main account can modify or revoke them at any time.This is the network's second attempt to introduce this feature. The original version had vulnerabilities that attackers could exploit to make others pay transaction fees with improperly signed transactions, and by repeatedly submitting high-fee transactions, they could deplete the victim's XRP balance. This vulnerability was reported by community testers on September 15, 2025, and validator nodes were advised to reject the amendment, so it was never activated. The fixed version was released with xrpld 3.3.0, changing the way unauthorized transactions are rejected, ensuring that fees are not deducted before signature verification.

The Alpenglow upgrade of the blockchain network Solana has entered the public testnet, where developers will test reducing transaction finality from about 13 seconds to 0.15 seconds, or 150 milliseconds. This upgrade will replace Solana's existing TowerBFT consensus system with Votor, allowing validators to confirm blocks through one to two rounds of direct voting, but the way users send funds will not change.The first testnet migration requires using Agave 4.3 and does not currently support Firedancer or Frankendancer. The mainnet update on September 28 is still a tentative arrangement and not a confirmed launch date for Alpenglow.

According to CoinDesk, Ripple stated that asset management companies and other commercial projects are preparing to use the Batch V1.1 feature of the XRP Ledger. This feature allows up to eight transactions to be combined into a single operation and ensures that all transactions either succeed or fail in an all-or-nothing manner, avoiding situations where one party completes settlement while the other fails.This upgrade is expected to support Delivery Versus Payment (DVP) transactions, allowing asset transfers and payments to be completed simultaneously, while also enabling exchanges, wallets, and market platforms to directly attach service fees to customer transactions for processing.RippleX Engineering Director Ayo Akinyele mentioned that some projects are already being developed around Batch, and once activated, it will bring related work closer to a production environment. Specific partners and launch times will be announced once plans are finalized. The amendment has received support from 30 of the 35 tracked validators on the XRP Ledger, exceeding the 28 votes required to enter the activation countdown. The countdown began on September 15, and if the validator support rate remains above 80% within 14 days, Batch V1.1 is expected to be activated shortly after September 29.Previously, researchers discovered serious flaws in the Batch V1 signature verification process in February, which could prematurely stop checking signatures under certain conditions, allowing attackers to unauthorizedly include transactions from other accounts. The developers subsequently withdrew the original version. Since the amendment had not yet been activated at that time, the vulnerability code did not run on the live ledger, and no funds were exposed.
