Setup

1. Download the zk circuits into ./circuits by running dl_circuits.sh. This will download the latest files from https://iden3-circuits-bucket.s3.eu-west-1.amazonaws.com/latest.zip

   ./dl_circuits.sh

2. Copy over the .env.example into .env
   You'll need to fill in RPC_URL and WALLET_KEY with your own endpoint and key respectively. The default env vars assume you will be using the Polygon Amoy network.

   cp .env.example .env

   example.env

   # reverse hash service url
   RHS_URL="https://rhs-staging.polygonid.me" 
   # state v2 contract address in the amoy network
   CONTRACT_ADDRESS="0x1a4cC30f2aA0377b0c3bc9848766D90cb4404124"
   # path to the circuits folder
   CIRCUITS_PATH="./circuits" 
   # url to polygon amoy network rpc node
   RPC_URL="" 
   # key in hex format with matic balance
   WALLET_KEY="" 
   # MongoDB connection string, uses in memory Mongo server if not specified
   MONGO_DB_CONNECTION=""
   

3. Install dependencies

   npm i 

Run

You can run each example function independently:

npm run start -- [function]

The [function] should be replaced with one of the following options:

• identityCreation
• issueCredential
• transitState
• transitStateThirdPartyDID
• generateProofs
• handleAuthRequest
• handleAuthRequestWithProfiles
• handleAuthRequestNoIssuerStateTransition
• generateProofsMongo
• handleAuthRequestMongo

To run all examples

npm run start
