Borrow Balance

A user who borrows assets from the protocol is subject to accumulated interest based on the current borrow rate. Interest is accumulated every block and integrations may use this function to obtain the current value of a user's borrow balance with interest.

  • account: The account which borrowed the assets.

uint borrows = fToken.borrowBalanceCurrent(msg.caller);
