[REQUIRED] Environment

• Browser version: Chrome - 114.0.5735.198
• AA SDK version: 0.1.0-alpha.14
• Package: alchemy/aa-core

[REQUIRED] Describe the problem

When someone tries to query for the CounterFactual address of the SimpleSmartContractAccount then the error Cannot read properties of undefined: getAddress is thrown

How to reproduce:

let provider = new SmartAccountProvider(
      "[rpc_url]",
      ENTRYPOINT_ADDRESS,
      sepolia
).connect((rpcClient) => {
    return new SimpleSmartContractAccount({
        entryPointAddress: ENTRYPOINT_ADDRESS,
        chain: sepolia,
        factoryAddress: SIMPLE_ACCOUNT_FACTORY_ADDRESS,
        rpcClient,
        owner: customClient,
    });
});

// Trying to query for the CounterFactual address of Smart Account
let address = await provider.account.getAddress();

Solution

This problem is caused because aa-sdk uses viem behind the scenes and when I am using rainbowkit connected wallet as my owner to the SimpleSmartContractAccount, it passes down the Wallet Client

Wallet Client has no getAddress method which is the root cause of the above error.

However, Wallet Client can be extended using the following code:

const { data: walletClient } = useWalletClient();
let newClient = walletClient.extend((client) => {
      return {
          getAddress: async function () {
              let addresses = await client.getAddresses();
              return addresses[0];
          },
      };
  })

The newClient in the above code will have the getAddress method which can then be used as the owner for SimpleSmartContractAccount like so

let provider = new SmartAccountProvider(
      "[rpc_url]",
      ENTRYPOINT_ADDRESS,
      sepolia
  ).connect((rpcClient) => {
      return new SimpleSmartContractAccount({
          entryPointAddress: ENTRYPOINT_ADDRESS,
          chain: sepolia,
          factoryAddress: SIMPLE_ACCOUNT_FACTORY_ADDRESS,
          rpcClient,
          owner: newClient,
      });
  });

@therealharpaljadeja Thanks for this summary! I'm actually going to re-open the issue so that we can add a utility to handle this in the future for others
