The walletconnect monorepo can be found here:

The utils package can be found here:

We should migrate to using URLSearchParams instead of the query-string package.

There is no node constraint as far as i can tell, so we should note we will be introducing one with this change.

if nesting is required, we should use fast-querystring or nested-querystring
