v1

On November 13, the 100% stablecoin-based exchange UXUY, incubated by Binance Labs and invested by YZi Labs, announced that its App's latest version v2.0.7 has officially launched the Social Trading v1 section, further connecting AI hotspot discovery, opinion exchange, and trading operations.In the UXUY App, the earnings leaderboard covers 7 days, 30 days, and all periods, allowing users to view traders' profit performance and review their opinions and judgment basis at the time of buying and selling, summarizing experiences based on trading results to optimize their own trading strategies. AI insights automatically filter popular tokens and push relevant social hotspot information in real-time, enabling users to publish text or voice opinions around related tokens, exchange market judgments, and complete transactions with one click. The personal homepage supports a centralized display of positions, profit and loss performance, and holding opinions, making it convenient for users to share asset allocation and holding logic.UXUY founder Kevin stated, "We are helping more users understand on-chain trading, understanding the decision-making logic of top traders through real holdings and opinions, lowering the understanding and participation threshold for on-chain trading. At the same time, we are also leveraging AI to filter truly useful market information for users, discover potential profit opportunities, and provide assistance for asset research and trading judgments."

Keystone hardware wallet announced that the Nexus App recently experienced a network attack, causing some users to be unable to use the app normally for a period of time. The team has responded quickly and strengthened server security. According to the current investigation results, no evidence has been found that user assets or personal information have been affected.Nexus App version 1.3.7 has further strengthened security measures and is now available on Google Play, while the iOS version is still awaiting App Store review. The official recommendation is for users to update as soon as possible and to confirm that the app developer is "Yanssie HK Limited" before installation to guard against counterfeit applications. Before the iOS version goes live, users can use third-party wallets supported by Keystone for signing.

DeFi risk management organization Gauntlet has closed the supply queue of its V1 vault, suspended asset allocation, and reduced exposure to LayerZero cross-chain bridge assets following the report of an op-reth vulnerability on certain OP Stack chains. Gauntlet stated that, to its knowledge, there have been no reports of the vulnerability being exploited.The report indicated that clearing the supply queue will prevent new deposits into the vault, but this measure will not close the withdrawal function or the underlying lending market; withdrawals will still depend on the liquidity available in the underlying market. Gauntlet stated that the relevant measures will remain in place until the issue is resolved, but did not provide a specific recovery timeline.Gauntlet is a risk curator for DeFi lending protocols, providing risk management services for vaults on protocols like Morpho, responsible for setting collateral parameters, supply caps, and asset allocation strategies. This adjustment involves its V1 vault operating on the relevant chains.

The prediction market revenue protocol Robin Markets announced the shutdown of V1. The team stated that the initial version of the revenue product did not achieve the expected adoption and will be gradually phased out to allow for the re-launch of an improved version. The points program, revenue guarantees, and matching rewards will cease along with V1; these mechanisms were originally intended to incentivize liquidity but did not perform as expected. Existing products will continue to operate until the new version is launched by the end of this year.The team outlined two main issues. The first is position matching: V1 needs to match opposing YES and NO positions within each market's liquidity pool to combine funds into USDC for use, and the efficiency of funds depends on whether the distribution on both sides is relatively balanced. This creates a first-mover disadvantage, as tokens deposited early often remain idle before a counterparty appears, resulting in thin liquidity pools, and early users frequently cannot earn returns. The second issue is changes in the revenue environment: at the project's launch, the yield on USDC.e on Polygon was still considerable, and there was a partnership with Yearn; after October 10, more yield channels on Polygon shrank or lost competitiveness, weakening the original sources of revenue and placing greater pressure on subsidy guarantees. The team stated that insufficient matching and weakening revenue mutually influence each other, hindering the product's actual operation.Robin Markets positions itself as the capital efficiency layer of the prediction market, allowing users to stake Polymarket outcome tokens on Polygon while earning returns without losing their original market exposure. Public information shows that the project previously completed a $475,000 angel round of financing, with investors including Fabric VC, Animoca Brands, ATKA Incubator, John Lilic, Stefan D. George, and angel investors from Hilbert Capital, LayerZero, and others. The team stated that the next version will directly address the issues of matching mechanisms and revenue sources.

Circle will reduce the limit of the old version of the USDC cross-chain protocol CCTP V1 starting from October 31 and plans to suspend the contract on December 1. In addition, the Noble chain will not connect to the new version of CCTP.Circle plans to suspend its USDC contract and remaining cross-chain routes on January 12, 2027. Holders on Noble need to withdraw USDC before this date. Circle will take a snapshot of the remaining balance on the day of suspension and will start manual redemptions from January 13. Applicants must meet compliance and security requirements, and the assets must be in a self-custody wallet.

Circle announced that it will gradually phase out the old cross-chain transfer protocol CCTP V1 and will begin reducing the cross-chain destruction limit for the old USDC starting October 31. This process will last for one month, during which transfer performance will gradually decline until the V1 contract is completely suspended on December 1. At that time, any integrations still pointing to V1 will no longer be able to transfer USDC across chains.This migration aims to encourage developers to transition to CCTP V2. CCTP V2 offers standard transfer and fast transfer modes and introduces programmable hooks functionality, allowing automated actions to be triggered once USDC reaches the target chain. Currently, CCTP V2 supports 27 blockchains, and Circle states that new integrations should be built directly on V2.Regarding fund security, Circle emphasizes that pending redemption requests will still be available during the phase-out period. The company will maintain a minting limit above the total amount of pending proofs to ensure that all pending redemptions can be processed before the V1 contract is completely suspended. This transition plan aims to achieve a transparent, predictable, and minimally disruptive migration.

Stable officially announced that the Stable mainnet will be upgraded to v1.9.0 on October 31 at 17:00 (UTC+8), with a block height of 45,091,000.This upgrade mainly includes protocol security reinforcement and network resilience optimization, aiming to enhance the security, reliability, and operational stability of transaction processing and settlement, providing infrastructure support for on-chain payments, exchange settlements, and corporate financial asset management activities.

The native decentralized liquidity layer of Bitcoin On Nexus tweeted that its old trading platform DotSwap V1 was attacked. The attacker exploited a legacy server-side signing mechanism, transferring approximately 8.5 BTC, worth about $685,000, from the V1 liquidity pool and accounts within about 4 hours.

On October 26, B.AI announced the official launch of Android App version 1.3.0. The new version supports 11 language options, breaking language barriers and providing a more convenient AI experience for users worldwide; it also completes a comprehensive performance upgrade, with faster response times and smoother operation.Users can visit the B.AI official website to scan the QR code in the upper right corner, or go to Google Play to search for and download the latest version, enabling mobile AI experiences anytime, anywhere.

According to The Defiant, the decentralized lending protocol Zest Protocol deployed on Stacks announced that October 23 will be the deadline for the exit of aeUSDC in Stacks Market V1, requiring users to complete the migration of relevant positions before this date.Since Stacks Market V2 only supports the USDC-backed stablecoin USDCx issued in partnership with Circle, the migration process from V1 to V2 will not automatically transfer aeUSDC positions. Users must first withdraw aeUSDC liquidity from V1, then directly exchange aeUSDC for USDCx via Bitflow, and finally deposit USDCx back into the V2 application.Another option is to cross-chain aeUSDC from Stacks to USDC on Ethereum via Allbridge Classic, and then use Circle's cross-chain bridge to transfer USDC from Ethereum to USDCx on Stacks. The Zest application will prompt users while they still hold V1 liquidity, supporting one-click migration of positions other than aeUSDC to V2.

Neura posted on platform X that it will take down the v1 test network and Neuraverse and enter the next phase. The team has completed a full snapshot of the points balance, leaderboard, task completion status, and activity history to ensure that no data is lost.

The governance organization of Ethereum Name Service ENS DAO published a new proposal on X, suggesting the activation of ENSv2.The proposal plans to freeze new v1 .eth registrations, allowing domains that have not yet migrated to continue renewing and retaining existing domains, and subsequently transitioning the domain registration and resolution functions to v2.

The proposal for the activation of ENSv2 for Ethereum Name Service (ENS) states that after the official launch of ENSv2, new registrations for ENSv1 will cease, while existing .eth domain holders will not face a migration deadline and can continue to retain and use their registered domains.The proposal also arranges for ENS Labs to transfer its remaining management roles for ENSv2 to the ENS DAO, handing over the relevant management authority to the community.

Solana real-time application project MagicBlock announced on X that MagicBlock v1.0 has launched on Solana, after approximately a year and a half of development.MagicBlock stated that the application can run in real-time without leaving Solana, proving the fairness of each result while maintaining payment privacy. The team also released the complete documentation for Validator v1.0.

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.

The Batch V1.1 upgrade for the XRP Ledger is just one vote away from initiating the activation process. The RippleX team has fixed 11 software defects in the latest review. The Batch feature allows users to combine up to eight related transactions into a single operation, ensuring that both parties complete the transfer simultaneously when two people exchange tokens, thus avoiding the situation where one party pays while the other fails.In Tuesday's snapshot, the upgrade received support from 27 out of 35 trusted validators, accounting for approximately 77%, while changes to the XRP Ledger require an 80% support rate. Therefore, currently, one validator's vote can determine success or failure, and obtaining one more vote will initiate a two-week activation countdown. The support rate must remain above this threshold for 14 days, during which validators can change their votes.Previously, researchers discovered vulnerabilities in the original Batch proposal, allowing attackers to initiate transactions using others' accounts without authorization under specific conditions; this version was not deployed on the mainnet. The new version was released with xrpld 3.3.0 on August 6, and the latest review found 11 issues related to signatures, authorization checks, and server crashes. Among these, a serious vulnerability rated by the security company Common Prefix could allow attackers to reuse user signature permissions to execute transactions beyond expectations. RippleX stated that the review involved four senior engineers, audits from Halborn and Common Prefix, public security competitions, and automated testing, and mentioned that commercial projects using Batch have been signed or are in development.

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.

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.

According to on-chain detective Specter monitoring, Balancer is suspected to have encountered a V1 attack, with an attacker continuously transferring funds, currently profiting $250,000. The related address is 0x112...E0aE.
