  await MintHelper.mintCccsList([mintCcc], wallet);

  // --- Burn CCC
  final etps = await MintHelper.getExchangeTradePositions(wallet);
  List<BurnCcc> burnCccs = new List();
  etps.forEach((etp) {
    final burnCcc = BurnCccHelper.fromWallet(
      wallet: wallet,
      amount: StdCoin(
        denom: etp.credits.denom,
        amount: etp.credits.amount,
