Evaluates the transaction by calculating the exunits for each redeemer, applying them, and returning the redeemers. This makes a remote call to the provider in most cases, however may use a virtual machine in some implementations.
The transaction to evaluate.
The additional unspent outputs to consider.
Retrieves the parameters for a transaction.
Get the slot config, which describes how to translate between slots and unix timestamps TODO: this is brittle; in theory this should work with the era histories; also, networkName is awkward
Retrieves the unspent outputs for a given address and asset.
The address to retrieve unspent outputs for.
The asset to retrieve unspent outputs for.
Resolves the script deployment by finding a UTxO containing the script reference.
The script or its hash to resolve.
Optionaladdress: AddressThe address to search for the script deployment. Defaults to a burn address.
This is a default implementation that works but may not be optimal. Subclasses of Provider should implement their own version for better performance.
The method searches for a UTxO at the given address (or a burn address by default) that contains a script reference matching the provided script or script hash.
const scriptUtxo = await provider.resolveScriptRef(myScript);
if (scriptUtxo) {
console.log("Script found in UTxO:", scriptUtxo.input().toCore());
} else {
console.log("Script not found");
}
The EmulatorProvider class implements the Provider interface. It provides methods to interact with the Emulator.
