trait FutureLift[F[_], Future[_]] extends ~>[[A]F[Future[A]], F]

A type class for conversions from scala.concurrent.Future or other Future-like data type (e.g. Java's CompletableFuture).

N.B. to use its syntax, you can import monix.catnap.syntax:

import monix.catnap.syntax._
import scala.concurrent.Future
// Used here only for Future.apply as the ExecutionContext
import monix.execution.Scheduler.Implicits.global
// Can use any data type implementing Async or Concurrent
import cats.effect.IO

val io = IO(Future(1 + 1)).futureLift

IO provides its own IO.fromFuture of course, however FutureLift is generic and works with CancelableFuture as well.

import monix.execution.{CancelableFuture, Scheduler, FutureUtils}
import scala.concurrent.Promise
import scala.concurrent.duration._
import scala.util.Try

def delayed[A](event: => A)(implicit s: Scheduler): CancelableFuture[A] = {
  val p = Promise[A]()
  val c = s.scheduleOnce(1.second) { p.complete(Try(event)) }
  CancelableFuture(p.future, c)
}

// The result will be cancelable:
val sum: IO[Int] = IO(delayed(1 + 1)).futureLift
