hello, I am developing a mobile app whose mission is to send and receive assets. I am using this api to make the sending transactions, but it gives me a problem, and I always get the error “Fail with error ‘ERC20: transfer amount exceeds balance’”, I am new in this world and I do not understand very well what this error refers to, since the account that is sending the assets if it has the necessary assets. And the relay account that I have created does have to pay the gas fee, I have tried with several transactions and it does charge the fee. So, I do not understand what could be happening, I was also looking in the documentation for the address of the trusted forwarder of sepolia but I have not found it, if you have it, could you send it to me? Thank you very much
We have minimal documentation for the forwarder (see here). Can you share your transactions on sepolia?
