# CMTA DACS

The CMTA Digital Assets Custody Standard (DACS) is the Capital Markets and Technology Association's published standard for digital asset custody controls, covering key generation, storage, backup, and operational governance. It gives banks and auditors a common benchmark for custody security beyond generic IT frameworks.

## Using DACS in custody due diligence

DACS translates custody-specific risks, key ceremonies, air-gapping, quorum controls, backup distribution, into auditable requirements, letting institutions compare providers against one published bar instead of bespoke questionnaires.

Taurus aligns Taurus-PROTECT with CMTA DACS, including audited key ceremonies, and contributes to the CMTA standards ecosystem alongside CMTAT for tokenized securities.

FAQ:

- Why reference DACS in an RFP? It compresses months of security questionnaires into one requirement with defined evidence, and providers unable to show DACS-aligned controls reveal that early, before procurement invests further.
