"However, despite our efforts ... we have regretfully determined that we need to shut down BITFRONT in order to continue growing the LINE blockchain ecosystem and LINK token economy," the California-based company said in a statement on its website on Sunday.
Bitfront said the move is unrelated to recent issues among certain crypto exchanges that have been accused of "misconduct".
FTX, which was among the world's largest cryptocurrency exchanges, is now the subject of investigations by authorities for "criminal misconduct".
The company had filed for bankruptcy earlier this month, while cryptocurrency lender BlockFi filed for Chapter 11 bankruptcy protection on Monday, hurt by exposure to the collapse of FTX.
Bitfront said it has suspended new sign-ups and credit card payments as of November 28, and will suspend withdrawals on March 31, 2023. The company clarified that interest for deposits made between December 5 and December 11 will be paid out on December 13, 2022.
