How can I get the transaction instructions from VerisonedTransaction object

Question

I need to get all the transaction instructions from the Versioned transaction object. Any idea about this?

Answer 1

The instructions are available in the transaction's VersionedMessage, which you can access like this:

const compiledInstructions = transaction.message.compiledInstructions;

Each instruction is a record of the following type:

type MessageCompiledInstruction = {
  /**
   * Ordered indices into the transaction keys array
   * indicating which accounts to pass to the program
   */
  accountKeyIndexes: number[];
  /**
   * The program input data
   */
  data: Uint8Array;
  /**
   * Index into the transaction keys array indicating the
   * program account that executes this instruction
   */
  programIdIndex: number;
};
