import algosdk from "algosdk";
import MyAlgoConnect from '@randlabs/myalgo-connect';

const algodClient = new algosdk.Algodv2("",'https://node.testnet.algoexplorerapi.io', '');
const params = await algodClient.getTransactionParams().do();

const txn = algosdk.makePaymentTxnWithSuggestedParamsFromObject({
    suggestedParams: {
        ...params,
    },
    from: sender,
    to: receiver, 
    amount: amount,

const signOptions: SignTransactionOptions = {
    overrideSigner: overrideAccount
};

const myAlgoConnect = new MyAlgoConnect();
const signedTxn = await myAlgoConnect.signTransaction(txn.toByte(), signOptions);
import algosdk from "algosdk";
import MyAlgoConnect from '@randlabs/myalgo-connect';
 
const algodClient = new algosdk.Algodv2("",'https://node.testnet.algoexplorerapi.io', '');
const params = await algodClient.getTransactionParams().do();

const txn: any = {
