Eth1 Shard Demo

Prerequisites

• Install Docker Compose

Run Eth1 Shard Demo

git clone git@github.com:txrx-research/eth1-shard-demo.git
cd eth1-shard-demo

docker-compose up

Setup your local wallet

You may connect your wallet (e.g. Metamask) to the Demo Network.

When docker compose is up there is a gateway node mapped on the local host with JSON-RPC endpoint accessible at http://localhost:8545 as usual. To send transactions successfully you will have to set chainId = 20202 for the network configuration.

Once the network is set up, use the following private key to redeem an enormous amout of premined ETH dedicated for your needs:

0x0000000000000000000000000000000000000000000000000000000000000001
