Creating a wallet

final derivationPath = "m/44'/118'/0'/0/0";
final networkInfo = NetworkInfo(id: "", bech32Hrp: "cosmos", lcdUrl: "");

final mnemonicString = "final random flame cinnamon grunt hazard easily mutual resist pond solution define knife female tongue crime atom jaguar alert library best forum lesson rigid";
final mnemonic = mnemonicString.split(" ");
final wallet = HexWallet.derive(mnemonic, derivationPath, networkInfo);

Creating a transaction

final message = StdMsg(
  type: "cosmos-sdk/MsgSend",
  value: {
    "from_address": "cosmos1huydeevpz37sd9snkgul6070mstupukw00xkw9",
    "to_address": "cosmos12lla7fg3hjd2zj6uvf4pqj7atx273klc487c5k",
    "amount": [
      {"denom": "uatom", "amount": "100"}
    ]
  },
);

final stdTx = TxBuilder.buildStdTx(stdMsgs: [message]);

Signing a transaction

final signedStdTx = TxSigner.signStdTx(wallet: wallet, stdTx: stdTx);
