@alko89 Could this be due to the provider you are using not supporting eth_signTypedData? Usage should be as simple as calling it with TypedSigningData as per the function signature. If you can provide an example of what you're trying that would help diagnose.

[alko89]

Yes I think this was also the case. I ended up calling the providers send function directly.

However when looking at the code I noticed dataToSign type is defined as dataToSign: { type: string; name: string; value: string }[] which would make it incompatible with EIPs structure (I might be wrong since I'm new to ts).
You can have a look at the sample structure in EIP712 example: https://github.com/ethereum/EIPs/blob/master/assets/eip-712/Example.js

@alko89 To be honest I implemented this very quickly to get it working in MetaMask a few months back. I wouldn't be surprised if it's now broken.

I will leave the issue open but will probably not get round to doing a proper job on this for a few weeks. I'll gladly accept a PR if you have the time yourself.

Is there any movement on this issue? We're trying to understand how to sign data using Web3x.

[alko89]

Unfortunately I'm not working on the project I have been using web3x for and am currently not involved in Ethereum development.

We were able to get this to work:

// Here, eth is an instance of Web3x/Eth.
// data is an instance of Web3x/Eth/TypedSigningData.
eth.signTypedData(state.account, data)
