Implementing useSimulateContract without User Connection

[0xSather]

Hi everyone,

I am using the useSimulateContract hook to fetch swap quotes in Algebra using the quoteExactInputSingle function. I am looking to make it work even when the user is not connected.

This is my current code:

const quoteExactInputSingleCall = useSimulateContract({
  address: '0x94Ca5B835186A37A99776780BF976fAB81D84ED8', // algebra quoter v2
  abi: algebraQuoterV2ABI,
  functionName: 'quoteExactInputSingle',
  args: [
    {
      tokenIn: '0x4300000000000000000000000000000000000004', // WETH in Blast
      tokenOut: '0x4300000000000000000000000000000000000004', // USDB in Blast
      amountIn: 1000n,
      limitSqrtPrice: 0n,
    },
  ],
});

Currently, when a user is not connected, I face a ConnectorNotConnectedError.

How can I modify the implementation to use the Blast network as a fallback when the user is not connected? Any advice or example code on handling this situation would be greatly appreciated.

You need to explicitly pass an account.
