private accountsForget ({ address }: RequestAccountForget): boolean {
    keyring.forgetAccount(address);

    return true;
  }

const _onForget = (): void => {
    if (!address) {
      return;
    }

    const status: Partial = {
      account: address,
      action: 'forget'
    };

    try {
      keyring.forgetAccount(address);
      status.status = 'success';
      status.message = t('account forgotten');
    } catch (error) {
      status.status = 'error';
      status.message = error.message;
    }
  };
  const _onGenesisChange = (genesisHash: string | null): void => {

() => {
        const status = {
          account: current.address(),
          action: 'forget'
        } as ActionStatus;

        try {

          );
          status.status = 'success';

          status.status = 'error';
          status.message = error.message;
        }

        onStatusChange(status);
