According to CoinDesk, Depository Trust & Clearing Corporation (DTCC), which provides clearing, settlement, and custody infrastructure, made the service available on October 28. Twenty institutions have signed agreements to access the system, which will initially operate on Canton Network and DTCC’s private Besu blockchain.

Participants include JPMorgan, Bank of America, Citi, Barclays, Morgan Stanley, UBS, Fidelity Investments, Citadel Securities, and State Street. These agreements cover access to the service; no figures were disclosed on how much of their assets the institutions have tokenized.

What Does the $30 Trillion Figure Represent?

At launch, 34 securities are eligible for tokenization, including shares of selected large companies in the Russell 1000 Index, ETFs, and U.S. Treasury securities with various maturities.

According to a DTCC spokesperson, the total market value of these securities is approximately $30 trillion. The figure represents the value of the assets that could be included in the service, not money moved onto a blockchain or trading volume.

With more than $114 trillion in securities held at DTCC’s depository, the new service is more than a standalone crypto product—it is a step connected to traditional market infrastructure.

Real Securities, Transfers Around the Clock

The tokens are backed one-for-one by securities held at DTCC subsidiary Depository Trust Company (DTC) and preserve the existing rights attached to those assets. Official ownership records will continue to be maintained at DTC.

Eligible institutions can tokenize their securities during business hours. DTCC is targeting a processing time of 15 minutes or less for these transactions. Once tokenization is complete, the assets can be transferred around the clock between registered blockchain wallets subject to compliance rules.

This structure differs from synthetic tokens that only track a stock’s price: These tokens represent actual securities held in custody. The service’s 24/7 transfer feature does not mean that round-the-clock stock trading open to all investors has begun.

Two New Networks in the 2027 Plan

DTCC plans to add Stellar and Circle’s Arc blockchain to the service in 2027. The roadmap also includes tools for settling transactions with digital money and using tokenized securities as collateral.

The service follows the SEC’s no-action letter issued last December for the tokenization of certain securities. The infrastructure, which was previously demonstrated and announced as a plan in May, has now moved into live use.

According to third-quarter results reported by The Block, Robinhood Chain, whose mainnet went live on July 1, generated $26 million for the company in its first three months. Excluding the network’s contribution, crypto trading revenue fell 6% from the previous quarter to $94 million.

The two items combined for $120 million in crypto revenue, 20% higher than in the second quarter. But the year-over-year comparison remains weak: total crypto revenue was still 55% lower than in the same period last year.

The new network generated about one-fifth of crypto revenue

Robinhood Chain’s $26 million contribution accounted for about 22% of total crypto revenue. Alongside the year-over-year decline shown in the third-quarter earnings report previously covered, this breakdown highlights the new network’s role in the quarterly recovery.

The layer-2 network built on Arbitrum generated more than $80 billion in decentralized exchange volume and over $50 million in network fees during the same period. The total fees generated on the network and the $26 million in revenue recorded by Robinhood are reported as different metrics.

Trading volume recovered from the previous quarter

Robinhood’s total crypto trading volume rose 23% from the second quarter to $49.8 billion. Of that, $20.6 billion came from the Robinhood app and $29.2 billion from Bitstamp.

The year-over-year volume decline noted in the earlier report and this quarterly increase compare different periods: crypto trading remained below last year’s level but recovered from the second quarter. Revenue from the new blockchain played a decisive role in offsetting the decline in trading revenue.

The latest investigation findings reported by Wu Blockchain revealed that the security breach at the hardware wallet manufacturer extended beyond customer records. The company said attackers obtained the WebAuth device verification key through the website breach.

According to Keystone, this key could allow counterfeit hardware wallets to pass the company’s official authenticity check. This puts the reliability of the check users rely on to determine whether the device they purchased is a genuine Keystone product at risk.

18,835 devices to be destroyed; shipments to be halted

The company announced that it will destroy 18,835 unsold devices that use the old verification key. Orders that have not yet shipped will be halted, and a different verification key will be used in new production.

The breach also affected 25,964 purchase records and 12,873 incomplete payment records. In the incident that previously made headlines over the leak of customer data, the latest announcement revealed a new risk related to verifying device authenticity.

What did the company say about users’ private keys?

Keystone said that recovery phrases, private keys, and the transaction signing process were not affected. The key that was reportedly compromised is used to verify a device’s authenticity; it serves a different function from the private keys that give users access to their crypto assets.

According to a statement reported by Wu Blockchain, the company detected unauthorized access to its official website on October 20. After reviewing API activity with Shopify, it confirmed on October 23 that customer data had been exposed.

The accessed information includes customers’ names, contact details, delivery addresses, the products they purchased, and the prices of those products.

Fake messages may include real order details

Keystone warned customers that the leaked information could be used in messages made to look as though they were sent by the company. These messages may cite reasons such as a refund, a replacement device, or a fix for an issue with an order.

Using genuine details such as the product purchased and the delivery address may make these fake messages seem more convincing. The company’s warning indicates that senders who know order details should not automatically be considered trustworthy.

Keystone: Private keys and recovery phrases were not affected

According to the company’s statement, payment card and bank details, recovery phrases, private keys, and wallet passwords were not among the exposed data.

Keystone reported that it had blocked the unauthorized access and fixed the security vulnerability. The process of notifying customers affected by the incident is also ongoing.

According to CoinDesk’s analysis, the issue for the companies is less about their shares being traded on a blockchain than about how those transactions are handled. Among those opposing the platform developed by OKX and Intercontinental Exchange (ICE), owner of the New York Stock Exchange, are McDonald’s, Goldman Sachs, Wells Fargo, and Cisco.

Microsoft and Alphabet’s objections had been disclosed earlier. The new assessment focuses on the decision-making behind the growing list.

What does it cost companies to stay silent?

Under the SEC framework described in the report, the platform notifies a company before making its shares available for trading. If the company does not object within 30 days, trading can begin.

According to an assessment by law firm Latham & Watkins, the rules provide no mechanism for objecting after that period has passed or for reversing an earlier decision not to object once trading has begun. As a result, questions that companies cannot resolve quickly may make objecting from the outset more attractive.

Dave Hendricks, CEO of tokenization company Vertalo, says some companies learn through a notification that third parties are tokenizing their shares. That raises questions such as who holds the shares underlying the token, how dividends will be distributed, and how voting rights will be exercised. According to Hendricks, if these issues cannot be clarified within 30 days, objecting is a reasonable choice.

Nasdaq also wants a different model for the technology it supports

Olivia Vande Woude, tokenization lead at Ava Labs, says OKX-ICE has drawn the first objections because it was the first platform to submit a notification under the SEC’s innovation exemption. In a system where objecting comes at no cost and silence means approval, she expects the list to grow.

Nasdaq’s approach also brings the debate over the model to the fore. The exchange operator, which supports tokenization, plans to object to its own shares being traded on these platforms under the current exemption. Nasdaq argues that transactions outside the existing national market system could fragment liquidity, weaken price formation, and fail to provide certain investor protections. Its own model aims to keep tokenized shares within the existing exchange system.

Will demand from new investors offset the risks?

According to Reid Noch of TD Securities, the expected benefits for companies are also not yet easy to measure. New investor demand could come from abroad, but it is unclear whether that would offset the risks of around-the-clock trading with low liquidity outside the familiar market structure.

By contrast, Securitize and BitGo said they would not object to their shares being listed on the OKX-ICE platform. Securitize CEO Carlos Domingo said the company is conducting outreach to help companies understand different trading models and shareholder rights.

According to CoinDesk’s review of on-chain records, the number of sgBENJI shares rose from about 48 million to 193 million. At the $1.039 share price recorded in transactions, the balance is worth approximately $200 million.

Behind the increase were two separate $75 million investments recorded in Franklin’s issuance account. More than 72.18 million new shares were created for each investment. The total $150 million investment thus substantially increased the fund balance on the network.

One wallet, one investor?

All of the new shares went to the wallet that already held the fund’s existing shares on the XRP Ledger. This wallet and Franklin’s issuance account authorize the same eight signing addresses; any two of those addresses can jointly approve a transaction.

It is not yet clear, however, whether the wallet represents a single investor or multiple clients. Brokers and custodians can hold shares belonging to different clients in a shared account while tracking individual ownership in separate records. Franklin’s fund documents also describe an off-chain recordkeeping system that links blockchain records to real-world identities.

Franklin had not responded to questions about the wallet’s structure or the number of investors behind the investments by the time this article was published.

What does sgBENJI invest in?

Each sgBENJI token represents a share in the Singapore-based Franklin OnChain U.S. Dollar Short-Term Money Market Fund. The fund invests in short-term U.S. dollar-denominated debt instruments, government securities, commercial paper, and bank deposits. Returns are reflected in the share price.

RWA.xyz puts Franklin’s value on the XRP Ledger at approximately $193 million. That figure is based on an assumed price of about $1 per share, while the $1.039 price in transaction records brings the total value to approximately $200 million. In the platform’s rankings, Franklin sits behind RLUSD, at approximately $930 million, and ahead of Ondo, at $185 million.

According to The Block, Netanyahu said in an interview aired Friday on Israel’s Channel 10 that the country should prepare for the possibility of economic sanctions. The prime minister said banking restrictions could also be imposed and argued that, in such a situation, the economy should be structured to overcome those obstacles.

Blockchain Cited as One Alternative

According to a translation of the Hebrew transcript of the interview, Netanyahu said he was also working on currencies that could help circumvent sanctions. When host Roy Katz asked whether he saw blockchain as an alternative to economic sanctions, he answered yes and said he had already asked for a plan to be prepared.

Netanyahu did not say which institution would conduct the work or which blockchain networks or currencies would be considered. He also did not provide a timeline for implementation.

Calls for Preparation for U.S. Aid Ending, Too

The prime minister said Israel should also prepare for the possibility that U.S. military aid could one day end. He emphasized that the tens of billions of dollars in support he said the country receives would not continue indefinitely, and argued that Israel should increase its capacity to produce its own ammunition and weapons.

Netanyahu said he had allocated an additional 400 billion shekels, about $129 billion, to the defense budget over the coming years. He also called for preparations for the possibility of a less favorable political climate for Israel in the United States after Donald Trump leaves office.

According to a statement reported by Wu Blockchain, Initia halted its L1 network and rollups at 18:41 Turkey time on October 23. The team is working with validators, exchanges, and security firms to determine the impact of the incident.

Mainnet and Rollups Halted

The decision covers both the main blockchain and connected networks known as rollups. Initia said in its statement that work to determine the scope of the security incident is ongoing.

Researcher Points to Unauthorized Token Minting

Security researcher @spreekaway said in a separate post that the attacker created tokens without authorization and cashed them out, obtaining approximately $2.6 million up to that point. According to the researcher, transfers of additional funds were also ongoing.

Initia has not yet confirmed the amount of losses or the technical cause of the incident. Therefore, the $2.6 million figure is being reported as the researcher’s assessment at that point, not as a confirmed total loss disclosed by the team.

According to a report by Wu Blockchain citing Axios, Visa is in talks with Fireblocks about an acquisition that would expand its presence in the digital asset sector. The approximately $2.5 billion figure cited in the report refers to the company’s valuation in a potential deal.

Visa is targeting crypto custody infrastructure

Fireblocks provides infrastructure for the custody of crypto assets. If the acquisition goes through, Visa is expected to expand its operations in both digital asset custody and blockchain-based payment infrastructure.

The report did not share details about the terms of the talks or how far they have progressed. The acquisition report has yet to be confirmed; as such, what is currently on the table is not a completed deal, but talks reportedly underway for a potential acquisition.

According to a report by Wu Blockchain, citing The Information, Andreessen Horowitz (a16z) is preparing to change both the fund’s name and its investment focus. The report also suggests that one of the fund’s founding members will leave.

The change may go beyond the name

The reported plan would allow the fund to invest in areas outside crypto as well. The proposed name change is therefore being discussed alongside an expansion of its investment scope. The report does not indicate a decision to end crypto investments entirely.

The latest fund was roughly half the size of its predecessor

a16z Crypto closed its fifth crypto fund at $2.2 billion in May 2026. The company’s fourth fund, raised in 2022, totaled $4.5 billion.

The amount raised for the new fund was thus roughly half the size of the previous fund. The reported plans concerning the name and investment focus have emerged after the difference in scale between the two funds, while the reported changes are not being presented as a completed withdrawal of capital.

According to Qubic’s statement, as reported by Wu Blockchain, the attack took place between 17 Ekim 23.42–18 Ekim 01.26 UTC, or 18 Ekim 02.42–04.26 Türkiye time. The attacker exploited insufficient randomness in generating the secret starting data, known as seeds, for certain wallets.

Flaw Found in Wallet Creation Process

A seed is secret data used to generate the keys that provide access to a wallet. Generating this data without sufficient randomness left the affected wallets vulnerable to attack. Qubic said the issue was with the seed generation mechanism, not the protocol itself.

As part of its response, the team halted network transactions at transaction step number 85.371.949, at the “tick” level, as the network calls it. Exchanges also suspended QUBIC deposits and withdrawals.

87% of Funds Frozen on the Network, the Rest in an Exchange Account

According to the statement, 87,1 percent of the stolen funds were frozen on the Qubic network. The remaining 12,9 percent had been transferred to MEXC; the recipient account holding these funds was also frozen.

As a result, the intervention was not limited to tokens on the network; an account-level restriction was also imposed on the portion transferred to the exchange. The next steps regarding the return of the funds to users depend on the network’s decision-making process.

Patch Released, Next Step Awaits Network Decision

Qubic said the seed generation issue was fixed in version 4.26.4. Under network rules, subsequent decisions on resolving the incident will be made by the required majority of network participants known as Computors.

According to the report published Thursday by the blockchain security company, losses from 107 attack incidents between July and September were up 55% from the previous quarter. A total of $906.8 million was linked to compromised vendor or developer tools, security patches that had not been applied, and components excluded from the most recent review.

What’s Behind the Audit Badge?

Hacken co-founder Andrii Matiukhin said the core issue is the scope of an audit. Because having every component that interacts with funds reviewed is costly, some teams audit only the parts they consider critical.

Even when specific smart contracts in a project have been reviewed, wallets, transaction-signing systems, and third-party software may fall outside the scope of that work. This creates a significant gap between the audit badge investors see and the areas they think have been checked; attackers can then access funds through a key, vendor, or configuration that has never been tested.

Withdrawal Infrastructure Was Targeted in the Bitget Attack

The report identified the Bitget attack in September as the largest incident of the period. According to Hacken’s findings, attackers exploited a vulnerability in a third-party security product to gain access to the exchange’s withdrawal infrastructure and stole at least $352 million.

In July, three crypto bridges and cross-chain protocols lost more than $35 million in total during a six-hour attack. Of that amount, $24 million was lost at AFX Trade, where attackers compromised validator keys.

Key Management Warning for Assets Worth $700 Million

Hacken also reviewed 12 derivatives trading platforms and prediction markets. It reported that more than $700 million in assets at two major platforms depended on a setup requiring signatures from three of four keys, or on administrator keys whose owners had not been publicly disclosed.

Matiukhin did not name the platforms, but emphasized that they found no evidence of an active vulnerability in the systems they reviewed. The criticism is that the key management setups in use are inadequate given the value of the assets they protect.

Another issue highlighted by the company is the failure to patch known vulnerabilities promptly. Blockchains using the same software may apply updates at different times; some teams may delay a fix by considering a critical vulnerability low risk. Hacken says companies holding customer funds should continuously monitor security vulnerabilities and apply patches promptly, rather than relying on an audit completed months or years ago.
