Who Holds the Keys? How Crypto Custody Works for Businesses

A company owns 500 BTC. The balance appears in its accounting records, but where are the coins actually held? More importantly, who can authorize a transfer?

These questions sit at the center of crypto custody. Unlike money in a conventional bank account, cryptocurrency is controlled through cryptographic keys. Whoever can use the relevant private keys can generally authorize transactions involving the assets.

For businesses managing substantial holdings, that creates an operational challenge. Access to funds has to be organized across employees, systems, and approval procedures.

The Difference Between Holding Crypto and Controlling It

A blockchain doesn’t record a company’s legal ownership in the same way as a corporate register. It records transactions between addresses.

Control over an address depends on the cryptographic credentials required to authorize transfers.

In a self-custody arrangement, an organization manages those credentials internally. With cryptocurrency custody, a specialist provider handles some or all of the key-management responsibilities under an agreed framework.

That distinction affects everyday operations.

If a finance employee leaves the company, for example, access permissions may need to change without disrupting the organization’s ability to manage its assets.

A professional crypto custodian may support defined approval processes, restricted access, and transaction controls. The exact arrangements differ between providers.

What Happens When a Transfer Needs Approval?

Consider a business preparing to transfer digital assets from its treasury wallet.

An employee creates a transaction request. Depending on the custody setup, the transfer might require approval from another authorized person before it can be executed.

Some systems use multisignature arrangements, where multiple cryptographic signatures are required. Others rely on multiparty computation, which distributes cryptographic operations without assembling a complete private key in one location.

These technologies serve related purposes but work differently.

In digital asset custody, technical controls are often combined with internal policies governing who can initiate, approve, and review transactions.

A secure technical setup doesn’t eliminate the possibility of human error, compromised credentials, or operational failures.

Why Storage and Trading Are Separate Questions

A company holding cryptocurrency may also use trading platforms. That doesn’t necessarily mean its entire treasury must remain in an exchange account.

Custody arrangements can separate asset storage from certain trading activities, although the available settlement models depend on the providers involved.

This distinction matters because an exchange balance and assets held under a custody agreement may involve different contractual relationships and counterparty risks.

The term crypto custody services covers several arrangements, from wallet management to institutional systems with access controls and reporting capabilities.

What Custody Doesn’t Solve

Even sophisticated key-management technology cannot prevent a cryptocurrency’s market price from falling.

Custody also doesn’t automatically guarantee insurance coverage, recovery of lost assets, or protection against every form of cyberattack. Such protections depend on the provider’s actual arrangements and contractual terms.

There are legal questions, too. Asset segregation, ownership rights, and treatment in insolvency can vary across jurisdictions and custody structures.

For businesses, custody is therefore about more than keeping private keys offline. It defines how digital assets are accessed, transferred, recorded, and controlled within an organization.
