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.

According to the official announcement, Gate has officially launched a new Proof of Security (PoSEC), becoming the first digital asset trading platform in the industry to propose a PoSEC security certification system, extending security verification from reserve adequacy to asset storage structure and risk protection.According to Gate's official page, as of the snapshot on November 4 at 08:00 (UTC+8), the platform's cold storage coverage rate reached 104.58%, with cold storage and hot wallet asset ratios being 88.26% and 11.74%, respectively. This means that according to the corresponding statistical criteria, even if all hot wallet assets are lost, cold storage can still cover all user assets. Currently, this data is being verified by an independent third-party auditing agency, and the report will be published on the official website once completed.In 2020, Gate was the first to launch an open-source Proof of Reserves (PoR) related program, and has since continued to strengthen a multi-layered security system that includes mechanisms such as the separation of cold and hot wallets, multi-signature, multi-party secure computation (MPC), and dynamic risk monitoring. The introduction of PoSEC further extends the verification of fund security from reserve adequacy to storage safety and extreme risk coverage capability, providing a new practical path for establishing a more comprehensive and transparent fund security standard for the industry.

On-chain lottery protocol Megapot announced that it will close the official application megapot.io and the Telegram application on December 1, shifting its focus to the enterprise-level lottery platform Prizerail, which operates independently of the protocol. Public information shows that the project has received support from Dragonfly and Coinbase Ventures. Megapot stated that the protocol itself will not change, remaining fully on-chain and permissionless, and applications or tokens built on this protocol can continue to operate. As of October 29, the official website and Telegram mini-program have stopped ticket sales; the liquidity supporter program, registration rewards, referral rewards, and guaranteed bonuses have all ended, and the points program is suspended. Bonuses that have been earned can still be claimed, and users can currently withdraw their balances without identity verification.Megapot explained that after December 1, on-chain lottery bonuses and referral fees can still be claimed through Basescan or third-party applications; guaranteed bonuses belong to off-chain projects and must be claimed before that date, with bonuses in the form of free lottery tickets available for claim in USDC. Accounts logged in with email, X, or Telegram must withdraw funds before December 1, after which the accounts will be unavailable; users who connect their wallets independently will still own their lottery tickets and bonuses. Liquidity providers can continue to provide liquidity or withdraw at any time, and the team stated that no new supporter programs will be launched. The data interface is currently considered deprecated, and the team will no longer maintain it, with services set to stop later.Regarding the reasons for the adjustment, Megapot stated that most applications use lotteries as rewards for deposits, transactions, and referrals, with the majority of the protocol's transaction volume coming from this usage. To serve larger-scale applications, the team launched the enterprise brand Prizerail, which generally requires compliance with U.S. regulations, provides legal memorandums to payment service providers, and does not wish to be associated with betting. The team stated that they have communicated with legal advisors and will provide the above capabilities independently of Megapot. Among the 20 potential clients generated after the introduction in Singapore, 19 chose Prizerail, and only 1 chose Megapot. There are already dozens of independent applications on the protocol, which have paid out over $1 million in bonuses, with ticket sales increasing threefold in the past three months, and the liquidity pool in the past month not relying on incentives for the first time.

According to CryptoBriefing, Ethereum Foundation researcher Justin Drake announced on November 3 that leanVM has achieved end-to-end formal verification. leanVM is a minimalist zkVM designed for efficiently aggregating hash-based post-quantum signatures, packaging multi-signatures into compact proofs. In terms of performance, leanVM can handle over 1000 leanXMSS aggregations per second; leanXMSS is a hash-based signature scheme planned to replace BLS at the consensus layer.At Devcon 8, Drake adjusted the target date for Ethereum's full transition to post-quantum security to December 2028, in order to allow space for the network forks needed for the transition. This plan relies on three open-source projects: leanVM, leanXMSS, and leanSpec. The Ethereum Foundation is developing open-source implementations and advancing formal verification, while also encouraging innovation through incentives like the Poseidon Prize. The report noted that the formal verification of leanVM proves that the code meets specifications, but December 2028 remains a target rather than a commitment.
