Function getUsdcToTokenRate

Example

provider.getNetwork().chainId: 1 (Mainnet)
tokenAddress: 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 (WETH)
result:
{
  tokenInAddress: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", (USDC)
  tokenOutAddress: "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2", (WETH)
  tokenInDecimals: 6,
  tokenOutDecimals: 18,
  rate: 0.000583026, (1 USDC = 0.000583026 ETH) => (1 x (10^6) USDC (in the smallest units) = 0.000583026 x (10^18) WEI)
};
