GetEnsResolver

The GetEnsResolver function.

The getEnsResolver function retrieves the resolver address associated with a given ENS name. It does this by calling the findResolver function on the ENS Universal Resolver Contract, which returns the resolver address for the given name.

The function takes an ENS name as input and returns the resolver address associated with that name. If the name does not have a resolver assigned, the function returns null.

The function also allows for specifying a block number or block tag to perform the read against, as well as an optional universalResolverAddress to specify the address of the ENS Universal Resolver Contract.

The getEnsResolver function is useful for retrieving the resolver address for an ENS name, which can be useful in a variety of contexts, such as when building Ethereum-based applications or when working with ENS names in general. It's important to note that ENS names can have certain forbidden characters and validation rules, so it's recommended to normalize ENS names with UTS-46 normalization before passing them to getEnsResolver. The built-in normalize function can be used for this.
