Mocking a Wallet Connection in a Wagmi + Next.js App

[frankfka]

Hey all,

We have a usecase where we have the private keys to a wallet, and we want to "mock" the connection (i.e connect the wallet as if the user has connected via a normal connector).

We would essentially want to set wagmi to the "connected" state with all the relevant information associated with this wallet.

Is there some sort of "WalletConnector" that is available? Or is there another suggested way of doing this?

Thanks!

@tmm I would think that this would be some variation of MockConnector, do you have any suggestions on how best to approach this?

Thank you!

Where I'm at now is:

async getProvider({ chainId } = {}) {
  const chain =
    config.chains.find((x) => x.id === chainId) ?? config.chains[0];

  const walletClient = createWalletClient({
    account,
    chain,
    transport: http(),
  });
  return custom({ request: walletClient.request })({ retryCount: 0 });
},

Everything else seems to work, but using privateKeyToAccount and an http transport doesn't seem to work with EIP1193 requests. Does viem/wagmi have an adapter that provides an EIP1193 compatible layer on top of a private key account, or do we have to implement this ourselves?

You can implement it yourself. Some examples:

• Wagmi mock connector
• Porto provider
