Google Debuting a Bank-Grade Crypto Custody Tool Built on Split Keys: Report

Google is reportedly unveiling Google Multi-Party Compute, a crypto custody system that splits signing keys across separate systems, at its first digital assets symposium in New York today. The product is in private preview with several financial institutions. Alphabet has started using it to secure its own assets, according to CoinDesk reporting.

Google plans commercial availability in early 2027 and has not disclosed pricing.

The system applies multi-party computation to a signing key. The key is divided into fragments held by separate parties or machines, and a transaction requires a set number of fragments to sign. 

The full key is never assembled in one place. A bank could hold one share on its own hardware, another in Google Cloud, and a third with a rival cloud provider. Institutions can set thresholds such as two-of-three or five-of-seven. Before any signature, a policy engine running inside Google’s Confidential Space checks the transfer against limits, destination restrictions, and approval rules. 

Google says it has no access to key shares in unencrypted form, per CoinDesk.

Crypto’s security issues

The pitch rests on a persistent problem. Chainalysis attributed 43.8% of cryptocurrency stolen in 2024 to compromised private keys. DeFiLlama data shows roughly 40% of the $16.69 billion lost to hacks through June came from key compromises. In June, an attacker took seven keys from one developer’s computer during the Humanity Protocol breach and drained wallets across two networks. 

Such incidents show how concentrated signing authority creates a single point of failure. The industry has responded by recommending multi-vendor multisignature setups that spread control across hardware and software providers.

Google also frames the product against AI-enabled fraud. Chainalysis found that scams linked to AI tool vendors averaged $3.2 million per operation in 2025, compared with $719,000 for other scams. The report links the two figures but does not prove that AI caused the difference. 

Ethereum researcher Justin Drake has warned that AI could eventually find mathematical shortcuts that weaken wallet signatures. No AI system has shown that capability. Google’s MPC design targets stolen credentials and unauthorized transfers, not a break in the underlying cryptography.

Quantum computing presents a separate, longer-term risk. Google researchers estimated that a sufficiently powerful future machine could derive a bitcoin private key from an exposed public key in about nine minutes. Roughly 6.9 million bitcoin have exposed public keys. Google says its architecture can adopt post-quantum signatures later without forcing institutions to rebuild their systems, but it has set no timetable. Background on how quantum machines threaten bitcoin explains which addresses are most exposed.

Google enters a market led by Fireblocks, Fordefi, and BitGo. Google argued to CoinDesk that its banking relationships and security expertise give it an advantage. It also positions itself as a neutral supplier for banks that do not want to rely on competitors. 

Banks already use specialized platforms, such as BNP Paribas’s custody work with Metaco, and multi-institution vaults built with BitGo.

Google is testing a crypto custody security system for banks, using multi-party computation to protect private keys and authorize institutional transfers.

A new Ipsos survey has found that only 19% of Americans strongly endorse the security of the US financial system, while just 5% express high trust in decentralized platforms. DeFi Education Foundation’s national study, conducted through Ipsos KnowledgePanel, surveyed 1,545…

Payward, the company behind crypto exchange Kraken, has agreed to acquire Lithuania-based Saldo Bank, taking a route into European banking that goes beyond obtaining another exchange registration.

TL;DR: The proposed acquisition would give Payward an existing licensed banking operation in Europe. The deal remains subject to regulatory approval and is expected to close in 2027.

Saldo provides banking products including loans and deposits. Bringing it into Payward would potentially put cash accounts, crypto assets and lending under a more connected product offering, rather than forcing customers to move between a separate crypto venue and their bank every time they need to borrow, spend or settle funds.

This is an important difference from a cryptocurrency firm simply partnering with an external payments provider. Ownership of a bank brings a regulated operating business, supervisory obligations and a different level of responsibility for customer money. Payward will not acquire unrestricted banking powers across Europe merely by signing the purchase agreement; the necessary approval and post-acquisition controls are still ahead.

The European push also fits a wider industry pattern. Crypto companies are pursuing banking relationships and charters as tokenized securities, stablecoins and conventional financial accounts become more closely linked. Existing lenders, meanwhile, are building crypto products of their own.

For Kraken users, the immediate message is about direction rather than a product they can use today. A completed acquisition could eventually make financing and fiat services feel less fragmented. Until regulators approve the transaction and the integration is completed, the promised benefits remain plans rather than available services.

Germany’s Sparkassen savings-bank group is beginning a phased cryptocurrency-trading rollout inside its existing banking app, taking an asset class it once treated cautiously into a familiar retail-finance setting.

TL;DR: The first participating Sparkassen banks are offering crypto trading from October 19. The rollout is gradual, with 30 to 40 institutions expected to join each month, and is handled through DekaBank.

There is no national switch that turns the service on for every customer at once. Each regional savings bank decides when to participate. The group’s association told German news agency dpa that the opening selection includes Bitcoin, Ethereum, XRP, Solana and Polygon, with a substantial number of interested institutions expected to be connected during the first half of 2027.

DekaBank is providing the service with Börse Stuttgart involved in custody arrangements. Customers can access the product through the Sparkassen app instead of creating a separate account at a crypto exchange. That convenience is central to the strategy, but the banks say the product is intended for customers making their own trading decisions rather than for a mass marketing drive.

The cautious messaging is deliberate. Sparkassen continues to describe cryptocurrencies as highly speculative and warns of steep volatility and total loss. Traditional savings products remain its preferred route for broad long-term wealth building.

This is a meaningful change for the German retail market nonetheless. Banks built on deposits and household relationships are responding to demand that previously went to specialist exchanges and mobile-first financial apps. How quickly individual branches opt in will matter more than the headline customer reach of the entire network.

TL;DR: Cross River Bank announced an integration of Ripple’s RLUSD stablecoin into its Core Operating System on October 15. The bank aims to give fintech customers access to blockchain settlement alongside conventional payment rails.

A US bank is adding a stablecoin to the machinery it uses to move money for fintech customers. Cross River Bank said on October 15 that it is integrating Ripple USD, or RLUSD, into its proprietary Core Operating System, with support for the XRP Ledger.

The idea is to make on-chain settlement another available route rather than an entirely separate payment product. Businesses connecting through Cross River’s platform could use stablecoin rails alongside familiar systems such as ACH, wire transfers and other bank payment services.

On the XRP Ledger, transactions are designed to settle in roughly three to five seconds at costs that can be a fraction of a cent. Those network characteristics help explain why Ripple is pitching RLUSD for cross-border payments, merchant settlement and treasury transfers that do not fit neatly into traditional banking hours.

There is an important gap between blockchain transaction speed and the full time required to deliver money to an end recipient. Compliance reviews, currency conversion and the off-ramp back into a bank account can all introduce additional steps.

For Cross River, which supplies financial infrastructure to other businesses, stablecoin support is part of a broader attempt to make different payment methods accessible through one integration. For Ripple, it gives RLUSD another path into regulated banking workflows.

Neither company described the deal as an overnight replacement for existing payment networks. The more realistic near-term picture is a bank adding another settlement tool, with actual adoption depending on which fintechs find it useful enough to integrate into their operations.

Deutsche Bank To Debut Bitcoin Custody Within Weeks: Report

German multinational Deutsche Bank is just weeks away from its crypto custody service, according to reports. 

The lender — which is Germany’s biggest — also plans to ​expand the custody platform into Asia next year​, according to a Friday Reuters report, which quoted its corporate banking chief. 

Top banks worldwide are debuting or planning to debut crypto custody services, with BNY Mellon, State Street, Standard Chartered, U.S. Bank, and Citigroup all committing to direct crypto custody over the past 18 months.

Deutsche Bank first officially announced plans to debut a bitcoin custody service for European corporate and institutional clients in September, with the German multinational at the time saying service was subject to the completion of the applicable regulatory timeline.

Friday’s report added that the service will support custody of ​major ⁠cryptocurrencies such as bitcoin before moving to services that help clients move money into and out of ⁠stablecoins.

Gerald Podobnik, co-head of the corporate ⁠bank, was quoted by Reuters saying that the financial system will need to “offer tokenized or blockchain solutions.” 

A number of top banks have started using the technology that powers bitcoin, the blockchain, for their own products in recent years. 

Stablecoins and tokenization in particular have become a hot topic as traditional financial firms aim to accelerate certain services. 

Crypto custody is often a starting point for banks moving into the digital asset space. BNY Mellon in 2022 became the first major U.S. bank to offer digital asset custody services.  

Banks like Citi and Standard Chartered have this year debuted or announced plans for bitcoin custody around the world.

Russia’s Central Bank Authorizes Sberbank to Exchange Cryptocurrencies

Russia’s central bank has added Sberbank to its register of organizations authorized to exchange digital currencies, according to reports. 

Sberbank was added to the list of digital depositories, which will keep a record of cryptocurrencies and digital rights, earlier this month. 

Now, it joins eight other organizations on the exchange register, including state-controlled VTB, Russia’s second-largest bank, and T-Invest Lab, part of T-Technologies, which also owns online lender T-Bank, according to a Monday report from Interfax. 

The announcement comes as Russia fast moves forward with Bitcoin-related regulation. Sberbank last month announced that it was the first in the country to have been approved to custody bitcoin. 

The Bank of Russia gave it the green light for “digital currency record-keeping” and to facilitate the transfer of such assets, covering bitcoin and other, smaller cryptocurrencies. 

“This status will allow the bank to provide services related to organizing the circulation of digital currency on interfaces which clients already use,” Sberbank was quoted saying in the news report. 

A law on digital currencies and digital rights came into effect in Russia on September 1, creating a comprehensive legal framework for cryptocurrency circulation. Transactions involving cryptocurrencies can be conducted via the existing infrastructure of exchanges, brokers and trustees, and now also via crypto exchanges and digital depositories. 

Cryptocurrency can be bought and sold via crypto exchanges, while the rights to these assets are recorded in digital depositories.

Banks and other organizations have been able to apply to the CBR for the corresponding licenses since October 5. Some existing players have simplified access to the market and can obtain licenses on a notification basis within just one day.

Under the new rules, unqualified investors will be able to buy bitcoin and other cryptocurrencies including stablecoins, within a limit of 300,000 rubles ($3,556) per year through one intermediary. 

Qualified investors will have access to all cryptocurrencies traded on the exchange and over-the-counter markets.

Sberbank will debut its crypto wallet in December — the same month the Moscow Exchange will debut crypto trading.

Russia’s Sberbank Given Green Light to Custody Bitcoin 

Russia’s largest bank has announced it is the first in the country to have been approved to custody bitcoin. 

Sberbank said in an announcement Wednesday that the Bank of Russia gave the company the green light for “digital currency record-keeping” and to facilitate the transfer of such assets. It said that bitcoin and other, smaller cryptocurrencies were given approval. 

Russia is fast moving ahead with regulating digital assets in the country. Russian President Vladimir Putin this month signed a law to set in stone the regulation of digital currencies and digital rights in the country.

“Customers will be able to conduct cryptocurrency transactions via SberBank Online, SberInvestments, and the SberBusiness online banking platform,” the bank said in a statement, adding that no new apps or platforms will be released. 

It added: “For users, this means that digital currency transactions are moving into familiar banking interfaces — complete with standard customer identification, transaction monitoring, and reporting.”

Before mass rollout, the bank will provide the service for a limited number of customers, it continued. 

Sberbank in July revealed plans to debut a Bitcoin and crypto wallet as well as digital asset custody by December. The Bank of Russia in July published draft regulations for crypto trading, and the State Duma has this year prepared the comprehensive regulation of digital assets.  

Despite the rollout, using digital assets as a means of payment or legal tender within Russia is still banned. Using crypto as a form of payment has been prohibited in Russia since 2022. 

President Putin has appeared to praise Bitcoin in the past, once saying that the leading cryptocurrency can’t be stopped.

Belarus Approves the Country’s First Crypto Banks: Report 

The first crypto banks have opened in Belarus, according to reports, after the European country earlier this year created a legal framework for Bitcoin banks. 

While not yet named, the crypto banks will start operations after obtaining accreditation from the National Bank of Belarus, Russian news agency Interfax reported Monday. 

Back in January, Belarusian President Alexander Lukashenko signed Decree No. 19 “On Cryptobanks and Certain Issues of Control in the Field of Digital Tokens,” officially creating a legal framework for bitcoin and crypto banks in the country.

“The practical outcome of today’s discussion is the launch and registration of the first crypto banks in the country’s history,” Interfax reported the press service of High-Tech Park saying in a statement.

High-Tech Park is a tax and legal regime in Belarus. Digital asset transactions are permitted in the zone. 

The statement added that banks would be regulated by Hi-Tech Park and the National Bank. 

Dmitry Kalechits, first deputy director of the High-Tech Park supervisory board secretariat, was quoted saying that the move would “improve the flow of the financial ecosystem” and drive foreign investment to Belarus. 

President Lukashenko last September backed the National Bank’s initiative to establish crypto banks in the country. 

The country has long pushed pro-crypto regulations. A 2017 decree legalised crypto mining and trading and temporarily exempted individuals’ crypto income from tax and declaration. That exemption was extended to 2025 and has since been narrowed, with income from foreign platforms now taxed at 13%.

Lukashenko has repeatedly promoted Bitcoin mining as a use for surplus electricity, and in 2025 the Mogilev region began preparing sites for mining farms with his backing.

TL;DR

• Tether says assets held with offshore banking partner EQIBank represent less than 0.034% of its total group assets.
• U.S. authorities are seeking forfeiture of tens of millions of dollars tied to EQIBank payment processor Capstone.
• Tether says it had no knowledge of the conduct alleged by prosecutors and has not disclosed the exact amount it holds with the bank.

Tether is trying to contain concerns around one of its banking counterparties after U.S. authorities seized assets connected with EQIBank’s payment infrastructure.

The USDT issuer says its exposure to EQIBank amounts to less than 0.034% of Tether’s total group assets.

Based on Tether’s latest reported asset base of roughly $187.75 billion, that percentage would imply a ceiling below approximately $64 million.

The company has not disclosed the actual figure.

The Seizure Is About EQIBank’s Payment Processor

The legal action involves Capstone Limited, a payment processor used by EQIBank to move customer funds through U.S. banking channels.

Federal authorities have sought forfeiture of assets held in accounts associated with Capstone, with court filings identifying roughly $83 million in bank accounts alongside approximately 1.18 million USDT from cryptocurrency addresses.

EQIBank has separately described the affected amount as roughly $89 million and warned that losing access to the funds could put pressure on its ability to continue operating.

Tether has confirmed that EQIBank provided banking services connected with USDT purchases and redemptions.

It also says it had no knowledge of the conduct U.S. prosecutors have alleged against Capstone.

No finding has established that Tether participated in the alleged misconduct.

Stablecoin Reserves Still Depend On Traditional Counterparties

The episode highlights a less visible part of stablecoin infrastructure.

USDT moves across public blockchains, but the reserves and fiat flows behind the token still interact with banks, custodians, payment processors and other conventional financial institutions.

That creates counterparty risk even when the token itself operates normally.

Tether has spent years diversifying its reserve portfolio and banking relationships, with much of its asset base now concentrated in highly liquid instruments including U.S. Treasury bills.

The company’s stated EQIBank exposure is small relative to its overall balance sheet.

But the situation shows why the quality and legal position of banking partners still matter to stablecoin issuers.

A token can settle globally in seconds.

The dollars behind it still have to move through a financial system where accounts can be frozen, intermediaries can fail and courts can seize assets.

For Tether, the immediate message is that the exposure is limited.

For the wider stablecoin market, it is another reminder that blockchain settlement does not eliminate traditional financial counterparty risk.
