Google crypto custody plans will bring a new service for financial institutions from Alphabet, whose shares trade under the GOOGL and GOOG tickers, according to Yahoo Finance. AOL reported that Google announced the platform, called Google Multi-Party Compute (MPC), on Oct. 28 and scheduled its commercial launch for early 2027.
The stock question turns in part on Alphabet's existing size. Yahoo Finance argued that the custody launch alone was not a reason to buy the company's shares and said the scale of its current revenue would make a substantial contribution from the new business difficult.
The service also has implications for cryptocurrency networks, though AOL described any potential benefit to Ethereum and Solana as mild. The outlet reported that Alphabet already uses MPC to secure some of its own digital assets on both chains.
How Google crypto custody works
According to Yahoo Finance, MPC divides a wallet's private key, the code that controls access to it, into several pieces. Those pieces are kept on separate, isolated computer systems, which can include servers operated by competing cloud providers, the outlet reported.
AOL reported that the design is intended to make it harder for an attacker to assemble a complete key and steal funds. Before spending is approved, Google's system checks it against the asset owner's rules, Yahoo Finance reported. AOL said those rules could include spending and transfer limits.
Cybersecurity is one concern for the institutions Google is targeting. AOL reported that 47% of financial institutions surveyed by American Banker in 2026 named cybersecurity as a leading barrier to adopting blockchain technology. Google argues that its relationships with traditional financial institutions will help it compete in custody, according to AOL.
Ethereum and Solana support
At launch, the Google crypto custody platform will support transaction-signing methods used by Ethereum and Solana, as well as other cryptoassets, Yahoo Finance reported. AOL identified those methods as ECDSA, used by Ethereum and other networks, and Ed25519, used by Solana and other networks.
Alphabet's own use of MPC covers assets on both Ethereum and Solana, according to Yahoo Finance and AOL. The signing support is not exclusive to those networks: AOL reported that ECDSA also secures Bitcoin and the ledger behind XRP.
AOL said Alphabet's use of the system was a positive factor for Ethereum and Solana, but argued that safer storage alone would not create demand among investors who did not already want the coins. The outlet also noted that large investors can already get custodied exposure through cryptocurrency exchange-traded funds.
Alphabet's revenue and the stock case
Google Cloud generated $30.7 billion in revenue in the third quarter of 2026, or 24.1% of Alphabet's $127.6 billion total, Yahoo Finance reported. In a hypothetical comparison, the outlet said $1 billion in MPC revenue in 2027 would amount to 0.8% of Google Cloud's annualized revenue.
That $1 billion figure was an assumption used in the comparison, not a stated MPC revenue target. Yahoo Finance argued that Alphabet's large revenue base limits how much the Google crypto custody business could add to overall sales, and questioned whether the Google brand would be especially valuable in crypto products.
The market is not empty: Yahoo Finance reported that numerous custody businesses already operate, including some with comparable security arrangements. Separately, AOL reported that the Motley Fool Stock Advisor analyst team did not include Alphabet among its selection of 10 stocks to buy. AOL said the Motley Fool holds and recommends Alphabet and several cryptocurrencies.
Other projects and the 2027 launch
MPC is not Google's only blockchain project. AOL reported that the company unveiled Google Cloud Universal Ledger, or GCUL, in 2025 as a network for financial institutions and other approved participants. According to AOL, Google is pitching it for uses including payments and the tokenization of assets such as stocks and bonds.
AOL argued that GCUL could compete with Ethereum and Solana for activity and capital, even as Google crypto custody supports assets on those chains. The outlet also argued that coins held in long-term storage contribute little transaction activity, distinguishing custody from actual use of a network.
Demand for existing investment products provides another piece of context. AOL reported that Ethereum ETFs had $635 million in net outflows over the first seven trading days of October 2026, while Solana ETFs recorded $24.8 million in net outflows. The outlet suggested watching ETF flows and bank announcements naming Google's service in the first half of 2027.
Conclusion
Alphabet is preparing an institutional custody service that divides private keys and checks transactions against owner rules, according to Yahoo Finance. The outlet reported that the system already protects some of Alphabet's own assets on Ethereum and Solana. Yahoo Finance argued that the launch alone does not justify buying the stock, citing the scale of Alphabet's existing revenue. The next concrete step is MPC's commercial launch, which AOL reported is scheduled for early 2027. AOL also suggested watching for bank announcements naming the service in the first half of that year.
