 To achieve this, you would:
 
 1.  **Create and Deploy a Custom `IApi3ReaderProxy` for `stETH/wstETH`**:
-
     - Since the `wstETH` contract's `stEthPerToken()` function doesn't directly implement the `IApi3ReaderProxy` interface, you'd first deploy a simple wrapper contract. This wrapper (let's call it `WstETHApi3ReaderProxyV1`) would call `stEthPerToken()` and expose the result (`stETH` amount for 1 `wstETH` with 18 decimals) and the current block timestamp via the `read()` method of `IApi3ReaderProxy`.
       _Note: An example of such a deployed custom proxy is `WstETHApi3ReaderProxyV1` at `0x3EA363B8CE16A26BFF70484883587DcF7E53C27d` on Ethereum mainnet. The development of this custom wrapper is outside the scope of the data-feed-proxy-combinators repository but illustrates how any data source can be adapted to be `IApi3ReaderProxy` compatible._
 
 2.  **Deploy `ProductApi3ReaderProxyV1` to calculate `stETH/USD`**:
-
     - This step multiplies the `stETH/wstETH` rate (from your custom proxy) by the `wstETH/USD` rate (from the Api3 dAPI).
     - Input `PROXY1`: Address of `WstETHApi3ReaderProxyV1` (e.g., `0x3EA363B8CE16A26BFF70484883587DcF7E53C27d` on Ethereum mainnet).
     - Input `PROXY2`: Address of the Api3 `wstETH/USD` dAPI proxy (e.g., `0x37422cC8e1487a0452cc0D0BF75877d86c63c88A` on Ethereum mainnet).

 To derive the desired uStETH/USD feed and make it compatible with the Api3 ecosystem, you can combine these feeds:
 
 1.  **Deploy `NormalizedApi3ReaderProxyV1`**:
-
     - This step adapts the external uStETH/ETH feed, which implements the `AggregatorV2V3Interface`, to the `IApi3ReaderProxy` interface. A key function of `NormalizedApi3ReaderProxyV1` is to read the `decimals()` from the external feed and automatically scale its value to the 18 decimal places expected by the `IApi3ReaderProxy` interface. For instance, if the uStETH/ETH feed returns its value with a different precision (e.g., 8 or 36 decimals), this proxy will normalize it.
     - Input `FEED`: Address of the external uStETH/ETH `AggregatorV2V3Interface` feed.
     - Output: An `IApi3ReaderProxy` contract. This deployed instance of `NormalizedApi3ReaderProxyV1` reads uStETH/ETH, with its value normalized to 18 decimals.
