Builtin Functions

Cardano Plutus provides a set of built-in functions that can be used in the scripts. Scalus implements them in the Builtins object.

Here are some examples of using built-in functions.


import scalus.builtin.*
import scalus.builtin.ByteString.*
import scalus.prelude.{*, given}
compile {
    // See scalus.builtin.Builtins for what is available
    val data = Builtins.iData(123)
    val eqData = data == Builtins.iData(123) || data != Builtins.iData(123)
    val eq = Builtins.equalsByteString(hex"deadbeef", ByteString.empty)
    val byteStringEq = hex"deadbeef" == ByteString.empty || hex"deadbeef" != ByteString.empty
    val stringEq = "deadbeef" == "" || "deadbeef" != ""
    val a = BigInt(1)
    val sum = a + 1 - a * 3 / 4 // arithmetic operators
    val intEquality = a == sum || a != sum
    val bool = !true || (false == true) != false && true // boolean operators
    val equals = a === sum // comparison operators
}
