PAS 19668:2020 Security tokens structure of the information and properties

PAS 19668:2020

Publication requirements for security tokens. Specification

Status : Current   Published : December 2020


What is PAS 19668:2020 about?
Until now there’s been no cross-blockchain industry-wide standard for security tokens. PAS 19668 fills that gap by specifying how information and properties relating to security tokens should be structured and presented.

Who is PAS 19668:2020 for?

  • UK and international security token issuers including blockchain companies and digital investment companies
  • Investors in security tokens
  • Token holders
  • Financial services companies including technical, financial and legal consultancies on tokenization
  • Security token exchanges, custodians and third parties providing services to security token issuers
  • Auditors checking conformity

Why should you use PAS 19668:2020?
Security tokens allow securities to be digitized in a manner that’s expected to increase openness and the inter-operability of the financial system. That said, up to now there’s been no standard on how information and properties relating to security tokens should be structured and presented. This has resulted in information being organized and presented in different formats and locations, making access highly inefficient and increasingly complex for investors and active market participants.

PAS 19668:2020 introduces a cross-chain standard that harmonizes the publication and access of security token attributes as disclosed by the asset issuer. It provides requirements for the publication of relevant information and the technical attributes of security tokens. It covers security tokens issued on any distributed ledger system.

For use by UK and international security token issuers, this is the first and only standard on the presentation of security token information and properties.

NOTE: This PAS does not cover utility tokens or unregulated tokens.


PAS 19668:2020 contributes to UN Sustainable Development Goal 8 on promoting sustained, inclusive and sustainable economic growth.
