Cairo: How can i approve erc20 and transfer in the same transaction?

You can make multicalls and batch many transactions that execute one after the other

See the following code from @bowlsofchili in Telegram:

export const constructTransaction = (contract, method, args = {}) => {



const calldata = stark.compileCalldata(args);



const transaction = {



contractAddress: contract.address,



entrypoint: method,



calldata



};



return transaction



};









export const sendTransactions = async (transactions) => {



try {



return await getStarknet().account.execute(transactions);



} catch (ex) {



return Promise.reject(ex);



}



};

see above, first method will help contruct individual txs and the second execute all of them at once
