@ricmoo
i am trying to submit erc 721 in react-native project but getting this error

when i change "transfer" to "transferFrom" there is no error but gasPrice value is null, how to fix. Or you can give me an example of send erc-721. Thank!

It could be a number of things, but my first guess is that the transfer method is either not in your ABI, or is not unique in your ABI. Can you include the ABI signatures for transfer from the ABI?
