Convert Wrap Token to Base Token

post

https://svc.blockdaemon.com/defi/v1/fungibletoken/convertwraptokentobasetoken

Enables users to convert wrapped ERC-20 tokens back to their underlying base tokens. For example, it allows for the conversion of wrapped staked Ethereum (wstETH) back to its base version (stETH). This unwrapping process is essential for users who need to access the native properties of a token for activities that require the base token format.
