A library to query Semaphore contracts.
This library allows you to query the Semaphore.sol contract data (i.e. groups) using the Semaphore subgraph or Ethers. It can be used on Node.js and browsers. |

Install the @semaphore-protocol/data package with npm:
npm i @semaphore-protocol/dataor yarn:
yarn add @semaphore-protocol/dataFor more information on the functions provided by @semaphore-protocol/data, please refer to the TypeDoc documentation.
