* Made client compile again + set auto fees * Simplified client construction by allowing only a single URL * wip * Simplified signing assertion * Initial implementation of queries * Implemented all basic nymd queries * Validator API queries * Signing related queries * Using default arguments * Removed redundant else branches * `eslint` and `prettier` formatting on Typescript validator client * Removed cyclic import on Coin type * Missing direct dependencies * Ingoring cyclic imports * Removed unused argument Co-authored-by: Mark Sinclair <mmsinclair@gmail.com>
