Google Cloud is previewing custody tech for banks, with launch planned for early 2027. Alphabet already secures its own ETH and SOL with it.

Since January 2025, 14 banks, brokers and exchanges have gone live with crypto custody, from Emirates NBD in March 2025 to Deka this month. Half of them are in Europe.

European banks like BBVA, BPCE, KBC and Deka hold the keys themselves. Most US retail offers rent them instead: PNC runs on Coinbase, E*Trade on zerohash and Schwab on Paxos.
