Crypto Custody for banks

Cryptocurrencies are becoming mainstream, and there is an increasing demand from retail and institutional clients to enable permissionless, 24/7/365, near real-time, low-cost crypto transactions. With the rise in demand, clients are looking to their banks to include these digital assets in their product offerings.

Crypto custody banks

Banks are the trusted financial institute for clients and are therefore in a unique position to onboard new and less tech-savvy users by developing tools that seemingly integrate cryptocurrencies with traditional banking services.

Rather than storing cryptocurrency with an unregulated startup company, clients may find it more convenient, accessible, and secure to hold crypto assets with a trusted financial institution. Banks, as trusted financial institutions, can fulfill the role of a trusted third party to keep cryptocurrencies safe.

For clients, it is convenient to have a single overview of all assets, including cryptocurrencies. While crypto-related financial services can generate new revenue models for banks.


“The digital asset ecosystem offers significant economic potential. It can facilitate more efficient transactions and unlock untapped economic value. The most promising use cases of digital assets in financial services are in cross-border trade and settlement, trade finance, and pre- and post-trade capital market activities..”

Crypto Custody

Safeguarding clients’ assets, be it cash, gold, securities, or virtual assets, is a paramount service for a bank. As with any other asset, this is also true for cryptocurrencies.

Cryptocurrencies are a new class of assets that fundamentally differs from traditional financial transactions because, technically, the asset exists on a public blockchain ledger such as Bitcoin or stablecoin such as Tether.

Banks can fulfill the role of the trusted third party to manage access to the private keys and ensure that only authorized transactions are signed and submitted to the correct network without exposing sensitive data.

Crypto Revenue Models

Banks add additional value for their clients by offering crypto custodial services, especially if crypto services are integrated into the financial bank infrastructure. Therefore, banks that provide crypto custody services into their existing platform will have a competitive edge over their competitors.

New revenue models include custodial services, brokerage, cold storage, trading, crypto loans, payments, and settlements.

Blockchain enables many more opportunities including Central Bank Digital Currencies (CBDC), stablecoins, asset tokenization, and Decentralized Finance (DeFi) services.
