# Custody technology provider

A custody technology provider supplies the software and hardware stack a bank runs to custody digital assets itself; the bank remains custodian of record with control of the keys. This differs from a third-party custodian, which holds keys on clients' behalf and becomes the counterparty.

## Why the distinction matters to regulators and clients

With a technology provider, the bank keeps the client relationship, the regulatory permission, and the keys; the provider is auditable software inside the bank's control framework. With a third-party custodian, clients take exposure to that custodian, and the bank outsources its core trust function.

Taurus is a technology provider: banks run Taurus-PROTECT in their chosen deployment, about one in four Taurus client institutions fully on-premises, and remain sole controllers of their keys.

FAQ:

- Is Taurus a custodian? No. Taurus is a FINMA-regulated securities firm providing custody technology. Banks run Taurus software, in their own infrastructure if they choose, and remain the custodian of record with exclusive control of private keys.
