Signer non-efemeral keys using GSN

[abcoathup]

Hi @Suzana_Maranhao,

We can use MetaMask to sign calls to be sent to relayers. We are signing a message, rather than signing a transaction (as in the case of MetaMask/metamask-extension#3475)

Sign GSN relayed call with MetaMask

I was asked if you can sign a Gas Station Network relayed call with a different key e.g. MetaMask account, rather than an Ephemeral Key. (but still have the transaction relayed via the Gas Station Network). I assume it is possible, though I don’t know what the setup needs to be. In the GSN Starter Kit which uses an Ephemeral Key the code is as follows: App.js: const signKey = useEphemeralKey(); // get GSN web3 const context = useWeb3Network(`wss://rinkeby.infura.io/ws/v3/${infuraToken…

It depends what abstraction you need for your users on whether MetaMask is suitable or you want to implement a persistent key.
