@lucid-evolution/scalus-uplc

Scalus-backed local UPLC evaluator adapter for Lucid Evolution.

import { Lucid } from "@lucid-evolution/lucid";
import { createScalusEvaluator } from "@lucid-evolution/scalus-uplc";

const lucid = await Lucid(provider, "Mainnet", {
  evaluator: createScalusEvaluator(),
});

The configured evaluator is used for local script evaluation. Passing localUPLCEval: false to complete still bypasses every local evaluator and forces provider evaluation.

const tx = await lucid
  .newTx()
  .collectFrom(utxos, redeemer)
  .complete({ localUPLCEval: false });

Lucid validates adapter results against the transaction's expected redeemer set before applying execution units. Missing, duplicate, or unexpected redeemer results fail the build instead of partially mutating the transaction builder.
