Crypto exchange Coinbase said Tuesday it’s working with PNC Bank, the fifth-largest commercial bank in the U.S. by assets, on a crypto project.

“In recent months, we have formed partnerships with industry leaders including [Tesla CEO] Elon Musk, PNC Bank, SpaceX, Tesla, Third Point LLC and WisdomTree Investments,” a letter from Coinbase to its shareholders read. When asked about the partnership by CoinDesk, the crypto exchange declined to elaborate.

The service would give the Pittsburgh-based national bank more seamless access to cryptocurrency investments for its customers, the source said. It's just one facet of PNC’s broader digital assets and blockchain strategy.

A since-removed job description for the Philadelphia-based position was more explicit:

PNC Bank didn’t return requests for comment.
