Mastercard Inc. said it’s working to weave Fiserv Inc.’s FIUSD stablecoin into a range of its payment products. It’s another traditional financial firm jockeying for a seat at the table as cryptocurrencies become more mainstream.

Mastercard said it was expanding its relationship with Fiserv to promote the financial tech company's planned stablecoin, FIUSD.

The publicly traded company also said it would let members of its cross-border payments network use stablecoins.
