The function config was not found. Maybe you did not declare it correctly or list all dependencies?

        if ('livenet' != $config['network'] && 'testnet' != $config['network']) {
            throw InvalidConfigurationException::invalidNetworkName();
        }

        if (!class_exists($config['key_storage'])) {
            throw InvalidConfigurationException::invalidStorageClass();
        }

        if ('' === trim($config['key_storage_password'])) {
            throw InvalidConfigurationException::invalidOrEmptyPassword();
        }

        $this->config = $config;

The property config does not exist. Although not strictly required by PHP, it is generally a best practice to declare properties explicitly.
