Command Line Interface
The command line interface (CLI) is made of three commands.

generate-group

The generate-group command is used to store a specific group of users in a JSON format in an off-chain database. You have to choose a valid Group Generator to run this command.
# generate a group with the 'ens-voters' Group Generator
yarn generate-group ens-voters
The mandatory argument is a valid generator-name, i.e a valid Group Generator.
You then have the following options:
--timestamp : Pass a custom timestamp for your group generation
--block-number : Use a custom block number for your group generation
--additional-data: Add additional addresses and data in the generated group. Multiple addresses must be separated by a coma while addresses and data are separated by an equality sign.
yarn generate-group ens-voters --additional-data 0x2a3..ab4=2,0x1e5..th0=4

send-to-attester

The send-to-attester command aims at sending generated groups on-chain. This command updates the on-chain registry tree by sending a new root.
# send groups on-chain for the 'hydra-s1-local' attester deployed on the 'local' chain
yarn send-to-attester hydra-s1-local local --send-on-chain
# send groups on-chain for the 'hydra-s1' attester deployed on the 'polygon' chain
yarn send-to-attester hydra-s1 polygon --send-on-chain
The two mandatory arguments for this command are:
attester-name: the name of your attester
network: the network where you attester is deployed
The following option is necessary to send the new registry root on-chain:
--send-on-chain: send available groups on-chain

api

yarn api:watch
This command allows you to launch a local api at this url: http://127.0.0.1:8000/static/rapidoc/index.html This swagger api can give information about:
  • all the available data on the different chains, sorted by attesters (polygon, polygon-playground, rinkeby, local)
  • all the created badges on the different chains
  • the metadata of a specific badge
  • a list of all the flows
