[bug] Wallet connect signer doesn't support signTransaction

Is there an existing issue for this?

• I have searched the existing issues

Package Version

^0.5.9

Current Behavior

  const provider = await connector.getProvider();
  const signer = await connector.getSigner();

  // this way to sign doesn't work at all, just returns 'UNSUPPORTED_OPERATION' or something like this
  const s = await signer.signTransaction({
    to: addr,
    from: userAddress,
    gasLimit: gasLimit,
    data: swapDescription,
  });

  // This one sends notification to my mobile, but doesn't work too for another reason (screenshot below)
  const r = await provider.request({
    method: 'eth_signTransaction',
    params: {
      to: addr,
      from: userAddress,
      gas: gasLimit,
      data: swapDescription,
      gasPrice: '0x9999'
    },
  });

Expected Behavior

signTransaction for wallet connect should work fine (example apps: 1inch, it has WC integration and it is possible to send tx via flashbots)

Hey @cattingcat,

Sorry I only just got the time to have a look into this. For now, you may have to try hook into the WalletConnectProvider instance on the Wallet Connect connector.

Example:

const { connector } = useAccount()

// ...

const provider = await connector?.getProvider()
const test = await provider.request({
  method: 'eth_signTransaction', 
  params: [{
    to: '0xA0Cf798816D4b9b9866b5330EEa46a18382f251e',
    from: '0xa5cc3c03994DB5b0d9A5eEdD10CabaB0813678AC',
    value: '0x0'
  }]
})

I tested this, and it works for me.

Yep, it works thanks 😃 Just in case if somebody will have the same issue as here: all tx values even gas should be in HEX format (I spent some time debugging issue with it)

Also Is it possible to migrate to signTransaction function sometime?
