Tips​

The tronWeb is a dynamic instance that will be reinitialized when necessary, so the recommend way to access it from FoxWallet:

  const provider = getProvider();
  const balance = await provider.tronWeb.getBalance(address);
  const signedMsg = await provider.tronWeb.signMessage(message, privateKey);
  ...

not recommend:

  const tronWeb = getProvider().tronWeb;
  const balance = await tronWeb.getBalance(address);
  const signedMsg = await tronWeb.signMessage(message, privateKey);
