This client enables to perform actions on KVStore contract and obtain information from both the contracts and subgraph.

. To use this client, it is recommended to initialize it using the static build
method.
A Signer
or a Provider
should be passed depending on the use case of this module:
Signer: when the user wants to use this model in order to send transactions caling the contract functions.
Provider: when the user wants to use this model in order to get information from the contracts or subgraph.
Installation
npm
yarn
