According to Cointelegraph, blockchain security company CertiK stated that although Google, Apple, and Microsoft have blocked 8 affected certificates issued by the Indian digital certificate authority eMudhra, cryptocurrency trading bots and exchange applications may still be exposed to related vulnerability risks, and browser fixes may not cover software that uses independent security systems.Peiyu Wang, Senior Director of Digital Asset Security at CertiK, pointed out that attackers could exploit the compromised certificates to impersonate exchanges, wallet interfaces, and APIs, replace deposit addresses, or induce users to approve malicious transactions. However, such attacks also require intercepting or redirecting network traffic, and the compromised certificate authority keys alone cannot expose wallet private keys. Cryptocurrency service operators should update software and certificate trust stores and ensure that applications reject affected certificates.

ARK Invest's Q3 2026 DeFi report shows that stock tokenization has become the main driving force behind the rebound in on-chain trading activity for the quarter. The trading volume of tokenized stock spot DEX reached approximately $50 billion, about 9 times that of the previous quarter, with its share of total spot DEX trading volume rising from about 1% to around 9%. Overall, DEX spot trading volume increased by approximately 13% quarter-over-quarter to $571 billion, marking the first growth in nearly four quarters.Robinhood Chain achieved approximately $65 billion in DEX trading volume and $51 million in network revenue in its first quarter, with network revenue nearing the level of BNB Chain during the same period. However, ARK expects that recent adjustments to the Gas mechanism will cause the chain's revenue to decline from current levels. The total supply of stablecoins decreased by about 3% quarter-over-quarter to $309 billion, but adjusted trading volume increased by approximately 16% quarter-over-quarter to $781 billion, with the number of monthly active addresses growing by about 39% to 73 million.In the perpetual contract DEX, there is a divergence between open positions and trading volume: the value of open contracts increased by about 76% quarter-over-quarter to $24 billion, while quarterly trading volume decreased by about 16% to $1.4 trillion. Among them, Hyperliquid's open contract value is about $13 billion, accounting for approximately 53%. ARK believes this indicates fewer but larger positions held for longer durations.

According to Coinglass data, in the past 24 hours, the total liquidation across the network was 327 million dollars, with long positions liquidated at 77.7935 million dollars and short positions liquidated at 250 million dollars.

Ledger Wallet officially launches the Crypto Loan feature, allowing users to directly use the Morpho open credit network for lending operations within the Ledger Wallet. The core of this feature is that users can use Wrapped Bitcoin (wBTC) or cbBTC as collateral to borrow stablecoins such as USDC or USDT without selling their assets.This integration brings hardware-level security standards into the DeFi lending space. All lending activities are physically confirmed through Ledger Signer, ensuring that every on-chain interaction from deposit to loan has clear signatures and hardware-level security guarantees. During the lending process, users' collateral remains in Morpho's smart contracts, with Ledger acting solely as a technology provider.Morpho is an open credit network running on Ethereum and major Layer 2s, providing flexible lending markets through infrastructures like Morpho Blue and Morpho Midnight. This feature supports operations such as adding collateral, repaying, increasing loan limits, and withdrawals. It is important to note that this service uses floating interest rates and carries liquidation risks, and users should pay attention to the specific supported countries and lending terms.

The lending protocol Lido Lend proposed by contributors will launch a withdrawal mechanism called Fallback Exits. When the market lacks sufficient liquidity of loan assets, lenders can utilize the collateral of borrowers to supplement withdrawal requests, and the corresponding debt of the relevant borrowers will be reduced. The protocol was launched on October 7 as a modified fork of Morpho Blue, built around isolated markets.According to the proposal, the collateral of borrowers will be passively utilized in order of the highest position risk, meaning positions closest to the liquidation loan-to-value ratio (LLTV) will be prioritized, while borrowers with very healthy positions are less likely to be affected. Taking the ETH/wstETH market as an example, lenders provide ETH, and borrowers stake wstETH to borrow ETH; if exiting through collateral, lenders will first be exposed to the staked tokens before receiving ETH. The proposal does not specify the qualification thresholds for healthy loans or the path for lenders to obtain ETH.Contributor Izzy stated in a post on October 16 that technical specifications and market parameters will be announced in the next two weeks, and the governance process and public audit must be completed before the mainnet launch. Details such as settlement valuation, debt offset formulas, fees, and limits have yet to be determined.

According to CoinDesk, Shinhan Card, a subsidiary of South Korea's Shinhan Financial Group, is collaborating with a subsidiary of Japan's SBI Holdings to explore the payment applications of a yen stablecoin between the two countries. Participants include the cryptocurrency exchange SBI VC Trade and the trade finance blockchain company SBI XDC Network APAC.The collaboration will study scenarios such as card-linked merchant payments for Japanese tourists visiting South Korea, wallet-to-wallet transfers, and cross-border trade settlements, and will include suspicious transaction monitoring and anti-money laundering compliance systems. Shinhan Card serves approximately 20 million cardholders and stated that it will connect this project with Shinhan Financial's broader digital asset strategy, which includes an agreement reached in August with Visa to explore stablecoin issuance, transfers, and card settlements.Currently, the project is still in its early stages, and the parties have not disclosed the types of stablecoins to be tested, nor have they set a timeline for testing or commercial rollout. SBI has previously issued the yen stablecoin JPYSC, launched by SBI Shinsei Trust Bank and introduced in collaboration with Startale Group, which had a circulation of approximately 20.1 billion yen (about 127 million USD) as of September 7. JPYSC is currently only available for use in SBI VC Trade accounts and cannot be transferred to external wallets. Its circulation on the public chain depends on legal and tax clarity and regulatory approval, and the parties have not indicated whether JPYSC will be included in this test.

The cryptocurrency wallet backup company Vault12 submitted a letter to the U.S. Securities and Exchange Commission (SEC), pointing out that the proposed token safe harbor framework fails to adequately alleviate concerns about the listing of tokens on centralized exchanges. Trading platforms remain worried about the potential for the SEC to retroactively challenge the legal status of tokens in the future.Vault12 raised $17.45 million from 38 investors in 2018 through a future token agreement, and its issued Vault Guardian Token (VGT) has yet to be listed on any centralized exchange. The project has fulfilled or formally abandoned all commitments in its white paper, but the exchanges previously contacted still require confirmation that the SEC will not determine in the future that VGT continues to be bound by the original investment contract. The SEC's proposed "Regulation Crypto Assets" plan introduced in August of this year aims to provide exemptions for token financing and allows eligible projects to terminate the association between tokens and the original investment contracts through a safe harbor mechanism. Vault12 suggests adding a 60-day objection period, during which if the SEC does not raise any objections, eligible filings should have final effect on the agency, except in cases of fraud or significant misrepresentation.
