How do i make it to approve the user token instead of the one i createdā€¦ should i just change the contract address?

#16

It should be the same process, you need to change the contract address. As @cryptokid mentioned, the approved spender can call a transferFrom method to send the tokens

#17

Ok Thanks for your replyā€¦ But what contract address do i change it to that will be able to approve the spender on all erc20 tokens.

#18

You need to call approve for a specific erc20 token. You can read more about approve here

#19

What if i want up to 7k token approval, I have to copy each smart contract address and use it on my dappā€¦ Thatā€™s very tiring.

Thank you for your replies you saved me from a lot of stress.

#20

last question how do i specify a specific token in my code?

#21

You can do an approval at a time from the client, you should be able to do multiple times using private key

#22

That should be the spender passed to the approve function if I got your question right

#23

My question is how do i specify the user to approve a specific tokenā€¦

for example a user has usdc and another one has busd how do make the approve function to know and approve the token

#24

pls someone should help me

#25

where should i copy the smart contract address to use?

#26

You can find it on the explorer or on coinmarketcap

#27

Youā€™ll have to determine that from your logics

#28

Thank you very much for enlightening me you saved meā€¦ but what do you mean by logicā€™s? .

#29

I mean within your code

#30

Ok thank you very much

#31

@qudusayo @cryptokid @wael_shikh @johnversus how do i automatically call the transferfrom on my smart contract when a user approves me to do the transfer on their behalf using javascript.

#32

You should have the transferFrom in your contract, after the user approves the function, you can then call your contract function which calls the transferFrom method for the other contract.

#33

God bless you manā€¦ should i use balanceOf if else statement to transfer a certain amount?

#34

You should have a logic to determine the value to be transferred maybe
