Mastercard Joins Blockchain Security Standards Council as Charter-Level Member

Mastercard has joined the Blockchain Security Standards Council as a founding member and will help shape security frameworks for blockchain networks and tokenized assets, with Claire Le Gal representing the company on the board.

Fact Check
The claim is well supported by consistent reporting across the Odaily article, the PANews article, and the X post. Crucially, Odaily points to the official BSSC announcement URL, and the search result for the official page explicitly says Mastercard joined BSSC as a Charter-level member on April 21, 2026. The PANews article further matches the claim's specific details: Mastercard will help define security frameworks for blockchain networks and tokenized assets, and Claire Le Gal will represent the company on the BSSC board. Confidence is medium because the official BSSC page itself could not be directly fetched in this run, but the official URL and search snippet strongly corroborate the secondary reports.
