@oskarszoon
Shouldn't theif tx.Version >= 2 be done just before the if !parsedUnlockingScript.IsPushOnly() {
once we make sure that there are not errors in the parsing of the unlocking script? So like this instead:

		parser := interpreter.DefaultOpcodeParser{}
		parsedUnlockingScript, err := parser.Parse(input.UnlockingScript)
		if err != nil {
			return err
		}

		// Chronicle release: version 2+ transactions allow non-push-only unlocking scripts
		if tx.Version >= 2 {
			continue
		}

		if !parsedUnlockingScript.IsPushOnly() {
			return errors.Join(ErrUnlockingScriptNotPushOnly, fmt.Errorf("input: %d", index))
		}
