London-based cryptocurrency custody firm Copper has given up its enterprise business, a software and infrastructure development side of the firm.

The reasoning was that Copper’s Clear Loop custody and settlement business made more economic sense going forward, a source close to the company told CoinDesk.

Copper's enterprise division was focused on securing digital asset custody and infrastructure solutions for banks and funds. There is a redundancy process but it's too early to say how many people will be affected, according to the source.

Copper was alerted to a security issue in December of last year involving the company’s GitHub repository, which contains a blueprint for how the firm secures customers’ assets. At the time, a source told CoinDesk the firm’s “entire code base was made vulnerable and downloaded.”
