I am trying to make working the transferFrom process. I follow the steps who are :

1. approve(address spender, uint256 amount) -> returning 1 so it is working
2. transferFrom(address sender, address recipient, uint256 amount) -> returning an error message : execution reverted: Insufficient allowance

I can confirm you that I have enough ETH in the two wallets to pay gas fees. I try to call allowance function but returning me 0...

If I call the balanceOf method of 0xbe71b68f1cbe13561ab882f590fa91c6d79dd193, I got in return : 0x0000000000000000000000000000000000000000000000056bc75e2d63100000 = 100000000000000000000

Please find the parameters for the two functions :

• The main wallet from which I would like to manage funds of my sub wallet : 0xe08b7d9464193616cb97086744caf8cae06a73c3
• The sub wallet : 0xbe71b68f1cbe13561ab882f590fa91c6d79dd193 Wallets are working on Rinkeby Test Network.

approve :

• Address : 0xe08b7d9464193616cb97086744caf8cae06a73c3
• Unit256 : 100000000000000000000000

transferFrom :

• Address : 0xbe71b68f1cbe13561ab882f590fa91c6d79dd193
• Address : 0xe08b7d9464193616cb97086744caf8cae06a73c3
• Unit256 : 100000000000000000000

So that's why I'm asking you some help on this, the approve call is working properly but not the transferFrom, and I don't know why...

Thanks
