Coinbase published an article introducing its user asset protection mechanism and stated that it has not been affected by the previous security incident involving Binance's hot wallet. Currently, the platform's system and user funds remain unaffected.Coinbase stated that over 99% of user assets are stored in cold wallets, with hot wallets only retaining a small amount of funds to meet users' daily withdrawal and usage needs, dynamically adjusting the balance based on deposit and withdrawal demands. The assets in its institutional custody vaults are all stored in cold storage and are independently isolated on-chain.In terms of fund transfer security, Coinbase employs distributed key protection, withdrawal limits, abnormal activity monitoring, and emergency stop mechanisms. Cold wallet private keys are split and stored, and the signing process does not fully reconstruct them; the key signing service in the hot wallet production environment does not allow single-person independent access. If abnormal transactions or a surge in withdrawal amounts are detected, the system will trigger an investigation and limit, and if necessary, can pause part or all fund transfers by shutting down the signing key.Coinbase also stated that user assets are always held by the users, and the platform holds assets on a 1:1 basis, without lending or misappropriating them without user instructions. As of September 30, 2026, the asset scale on the Coinbase platform reached $377 billion, holding $8.6 billion in cash and cash equivalents, and $2.2 billion in investment cryptocurrencies. The company stated that as AI capabilities develop and change the security risk landscape, it will continue to increase investment in security technology.

On-chain researcher Zeeme posted a lengthy analysis on X, explaining why hackers can attack Binance, Bybit, and Bitget, but find it difficult to breach Coinbase. He stated that Coinbase holds approximately 959,000 BTC, worth about $10.33 billion, and has not suffered such attacks in 14 years.Zeeme indicated that most exchanges concentrate billions of dollars in a few hot wallets for quick withdrawals; Coinbase, on the other hand, employs multi-party computation (MPC) technology, where the complete private key never exists on disk or in memory. Each key is split into shards upon generation and stored on isolated hardware chips.He compared that in October, after hackers compromised a DevOps personnel's computer at Binance and hijacked hot wallet signatures, they transferred approximately $6.36 billion within 20 minutes; whereas at Coinbase, even if they breach an engineer's computer, they can only obtain a useless shard of the key.Additionally, Zeeme later corrected that the approximately 69.8 million addresses mentioned in the post are Coinbase's deposit addresses, not the wallets holding funds, as Coinbase also has both hot and cold wallets.

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.

Cross-chain aggregator Jumper announced plans to conduct its first JUMP token sale through Legion, while independently splitting from its incubator LI.FI to become a standalone company. Jumper claims its lifetime trading volume exceeds $40 billion, with over 100,000 monthly active users, ranking first in cross-chain bridging transaction volume, holding a market share of over 15%. The company is expanding its coverage to include exchanges, cross-chain, perpetual contracts, tokenized stocks, and other real-world assets, as well as yield opportunities.Jumper CEO Marko Jurina stated: Cross-chain bridging is the starting point for Jumper, and hopes Jumper will be the application users open when trading, investing, or transferring value on-chain. Jumper Perps (aggregated perpetual contract venue) is set to launch in the coming weeks. LI.FI will focus on orchestrating infrastructure, while Jumper will concentrate on consumer-facing applications.This Legion sale will be Jumper's first financing, with proceeds aimed at accelerating product development, user acquisition, and distribution. The JUMP token is planned to launch separately after the financing. The company stated it will not conduct separate equity financing rounds, with JUMP intended to be the sole ownership and exposure asset for users, contributors, and investors. Jurina remarked: The token should be the only way to own the value created by Jumper, and token priority ownership should become the industry standard.

Attackers exploited a signature verification bypass vulnerability in the Kasplex KRC-20 off-chain indexer to transfer 186 million ZEAL and 54.398 billion NACHO without holding the private keys of the bridge custody wallet. They executed five forged transactions to mint the tokens through the Igra Labs EVM layer and Kasplex L2, then sold them to the Zealous Swap liquidity pool. The KAS side of the affected liquidity pool experienced a value loss of 94% to 99.6%.Igra has suspended iKAS withdrawals to Kaspa L1 and Hyperlane transfers, and has warned users to avoid bridging KRC-20 tokens, buying ZEAL or NACHO on the L2 DEX, and adding liquidity to the related pools. The Kaspa L1 consensus and unbridged Igra assets were not affected. Zealous Swap stated that the operators need to fix the indexer and re-index the history, rejecting transactions with empty signatures, abnormal tags, and transactions containing scripts after OP_ENDIF.

Recently, the meme coin market has been booming, and on-chain trading has become increasingly active. However, with the warming market, meme coin display pages have frequently shown highly disguised phishing links, and the "novel" attack methods have caused several seasoned traders to fall victim. Crypto KOLs @insidecalls and @cladzsol recently revealed that while scanning chains, they clicked on the meme coin homepage, which resulted in a "cloudfare verification" prompt. After completing the verification as instructed, the victim's on-chain funds were stolen. Among them, @cladzsol lost approximately $600,000 in assets.According to market news, on several recently popular meme coin display pages, the homepage redirects to a "cloudfare verification" page, which is actually a phishing link. If users follow the prompts, their computer systems will download and execute malicious scripts, leading to asset loss. This phenomenon is so rampant that it may be related to the delayed review processes of mainstream trading aggregation platforms like DexScreener. Currently, the display logic of relevant platforms is to directly reference the "official website" or social media links filled in the token metadata. These fields can be updated by token creators or those who later claim "community takeover." Hackers are exploiting this review loophole to transform meme coin display pages into new "fishing grounds" for phishing attacks. Users may inevitably click on unfamiliar links during the chain scanning process; if a "cloudfare verification" or other highly suspicious page appears, they should close it immediately to avoid interaction and protect their asset security.

According to the Science and Technology Innovation Board Daily, Samsung Electronics has begun developing its first AI glasses equipped with a display. This product not only provides audio functionality but also displays colorful visual information on the lenses, similar to the Meta Ray-Ban Display smart glasses.Industry insiders revealed that Samsung Electronics is considering developing an ultra-small screen with a size of only 0.2 inches or smaller for the AI glasses, and last month assigned this R&D task to Samsung Display, outlining requirements regarding product dimensions, information display area, color, and price. Samsung Electronics is currently evaluating candidate panel solutions such as OLEDoS or LEDoS, and the industry expects this product to be released in the second half of 2027 or the first half of 2028.Currently, the specific details of the glasses have not been finalized. In terms of color display, Samsung Electronics is expected to use a limited grayscale with 4-bit color instead of a high-definition screen, and it has not yet decided whether to adopt a binocular or monocular design. Industry insiders indicate that RGB OLEDoS faces challenges in terms of price and yield, and it is likely that a white OLEDoS panel will be launched. Samsung previously released AI glasses without a display, co-developed by Samsung Electronics, Google, Gentle Monster, and Warby Parker.
