Blockfrost.evaluateTransaction() method

This method evaluates how much execution units a transaction requires.

Signature:

evaluateTransaction(tx: Transaction, additionalUtxos?: TransactionUnspentOutput[]): Promise<Redeemers>;

Parameters

Parameter	Type	Description
tx	Transaction	The Transaction
additionalUtxos	TransactionUnspentOutput[]	(Optional) Optional utxos to be added to the evaluation.

Returns:

Promise<Redeemers>

A Promise that resolves to a Redeemers type
