Setup

After successful installation you need to go through four steps in order to place buy and sell orders with the tool. Setup requires editing config.json file which is located under ~/.pmarket-cli/config.json where ~ is your home directory.

1. You need to generate api key to access polygon network. I recommend using infura.io but you can use any other provider you like Steps to generate key. Once you generate the key set rpcProvider value in config.json file to your rpc provider url. Url should look something like this: https://polygon-mainnet.infura.io/v3/your-api-key

2. Generate your private key and set it in config.json file (privateKey entry). You can use metamask to generate private key. Steps to generate private key

3. You will need to generate an api key for polymarket. You can do this by running the following command:

pmarket-cli -k

Take values from the response and set them in config.json file (apiKey, apiSecret and passphrase entries).

4. Set allowance for CTFExchange contract. You can do this by running the following command. This will allow CTFExchange contract to spend your USDC tokens.

pmarket-cli -a 500

After all 4 steps your config.json file should have all entries filled with values.
