# Create a Client

```llvm
bun add @cityprotocol/core viem
```

Unlike `CityClient` (which only needs a wallet client), `CityLendingClient` requires a Viem `publicClient` for on-chain reads alongside a `walletClient` for signing transactions. You also pass in the active `account` explicitly.

```
import { CityLendingClient } from "@cityprotocol/core";
import { createPublicClient, createWalletClient, custom, http } from "viem";
import { mainnet } from "viem/chains";

const publicClient = createPublicClient({
  chain: mainnet,
  transport: http(),
});

const walletClient = createWalletClient({
  chain: mainnet,
  transport: custom(window.ethereum),
});

const [account] = await walletClient.getAddresses();

const lendingClient = new CityLendingClient({
  publicClient,
  walletClient,
  account,
});
```
