Polygon CDK Setup and Demo

This repo contains all the necessary steps to:

1. Transfer Funds from PreFunded Key on L1 to your wallet.
2. Deploy Contracts on L1.
3. Deposit Assets to L2.
4. Withdraw Assets from L2.

First follow the instructions here to setup a local CDK node. It will setup a local L1 (geth) and a local L2 (CDK Validium Node), alongside the DAC and the Bridge Service.

Once you ensure that the local L1 and L2 are running, you can run the following commands to ping the local L1 and L2.
