  We construct a new invariant of singular links through representations of the
singular braid monoid into the two parameters bt-algebra. Additionally, we
recover this invariant by using the approach of Paris and Rabenda. Hence, we
introduce the so called two parameter Singular bt-algebra. Finally, we provide
the skein relations that define our invariant, and we prove that this invariant
is more powerful than previous invariants of singular links in literature.
