Simple Scripts

Atlas supports simple scripts, also known as native and timelock scripts. The functionality of simple scripts is explained in the ledger design document of Shelley & Mary era here (opens in a new tab) and also in cardano-node-wiki (opens in a new tab).

Simple scripts can be specified via exposed constructors of GYSimpleScript (opens in a new tab). They can also be read from their JSON representation as GYSimpleScript has a FromJSON (opens in a new tab) instance. We also provide a utility function, readSimpleScript (opens in a new tab), to read JSON representation from a file.

Simple scripts can also be attached to UTxO outputs, allowing them to be used later as reference scripts when building transactions. You can find an example here (opens in a new tab), that demonstrates how to interact with simple scripts, both when used as a reference and when given directly for transaction validation.
