Are you working on a blockchain related project, and looking to develop an offer on Security tokens with renowned market participants?

The CAST CHALLENGE aims at offering open-source solutions for Security Tokens markets’ stakeholders compatible with the CAST Framework. It seeks to respond to existing problems met by financial institutions, most notably investors, to find efficient ways for the use of Distributed Ledger Technology and Security Tokens at bank-grade level.

The CAST (Compliant Architecture for Security Tokens) Framework is a new market standard and open source set of computer code components designed for the issuance, custody and trades of securities on a blockchain. It has been trialed and approved in substantial issuances made for years by systemic regulated institutions (banks, supranationals, brokers, etc.). The CAST CHALLENGE is the first fully online digital event related to the CAST Framework.

Create standardized open-source computer code components compatible with the CAST Framework. Get the opportunity to participate in real transactions of Security Tokens with international institutions.
