Quiero acceder al saldo del contrato (es decir 0x552F3AfaA0394632f4aEfa9E923fA3e2bbDAF5FE) y su suministro total (variable de estado). Podría acceder al saldo de este contrato, pero por qué no pude llamar a su función, es decir, getTotalSupply()tengo el siguiente código;
async function myContractAddress() {
myContAddr = '0x552F3AfaA0394632f4aEfa9E923fA3e2bbDAF5FE';
web3.eth.getBalance(myContAddr).then(console.log);
tokens = await myContAddr.methods.getTotalSupply().call();
tokens = tokens.toString(10);
console.log("Toten supply is : ",tokens);
}
myContractAddress();
aquí está mi error;

Lo que está haciendo mal está en su código myContAddr es una cadena y está intentando acceder a los parámetros de esta variable. Para acceder a .methods.getTotalSupply().call() necesita crear una instancia de contrato usando el siguiente código:
async function myContractAddress() {
var myContAddr = '0x552F3AfaA0394632f4aEfa9E923fA3e2bbDAF5FE';
var myContractAbiDefenition = 'CONTRACT_ABI';
var myContractInstance = new web3.eth.Contract(myContractAbiDefenition, myContAddr);
tokens = await myContractInstance.methods.getTotalSupply().call();
console.log("Tokens: ",tokens);
}
myContractAddress();
