hi, I want to send USDT with custom data, how can I do that?
I deploy en erc20 token ‘HelloWorldToken’ and I send a token to mysql with custom data ‘HelloWorld’,
the url is https://rinkeby.etherscan.io/tx/0xc1b54de98d2b8df5baf343d721ef8e245ff3ef6cfffa50bc848f28392a40347c
the data of this tx is as follow:
just as we all know,
a9059cbb is the function id of
000000000000000000000000ad61cc6653b62b7c05bd2f593bc49d22fb901a9c is the address, the
0000000000000000000000000000000000000000000000000000000000000400 is the amount,
and I add my custom data of
48656c6c6f576f726c64 (HelloWorld) to the end.
and the tx is ok, the token transfer from A to B.
Is there a EIP abount this on how to add custom data to the end of a token?
