# JoiningTestnet

This document outlines the steps to join the public testnet

## Steps

1. Install the Ethermint binaries (ethermintd & ethermint cli)

    ```bash
    git clone https://github.com/cosmos/ethermint
    cd ethermint
    git checkout v0.4.1
    make install
    ```

2. Create an Ethermint account

    ```bash
    ethermintcli keys add <keyname>
    ```

3. Copy genesis file

    Follow this [link](https://gist.github.com/araskachoi/43f86f3edff23729b817e8b0bb86295a) and copy it over to the directory ~/.ethermintd/config/genesis.json

4. Add peers

    Edit the file located in ~/.ethermintd/config/config.toml and edit line 350 (persistent_peers) to the following

    ```toml
    "05aa6587f07a0c6a9a8213f0138c4a76d476418a@18.204.206.179:26656,13d4a1c16d1f427988b7c499b6d150726aaf3aa0@3.86.104.251:26656,a00db749fa51e485c8376276d29d599258052f3e@54.210.246.165:26656"
    ```

5. Validate genesis and start the Ethermint network

    ```bash
    ethermintd validate-genesis

    ethermintd start --pruning=nothing --rpc.unsafe --log_level "main:info,state:info,mempool:info" --trace
    ```

    (we recommend running the command in the background for convenience)

6. Start the RPC server

    ```bash
    ethermintcli rest-server --laddr "tcp://localhost:8545" --unlock-key $KEY --chain-id etherminttestnet-777 --trace --rpc-api "web3,eth,net"
    ```

    where `$KEY` is the key name that was used in step 2.
    (we recommend running the command in the background for convenience)

7. Request funds from the faucet

    You will need to know the Ethereum hex address, and it can be found with the following command:

    ```bash
    curl -X POST --data '{"jsonrpc":"2.0","method":"eth_accounts","params":[],"id":1}' -H "Content-Type: application/json" http://localhost:8545
    ```

    Using the output of the above command, you will then send the command with your valid Ethereum address

    ```bash
    curl --header "Content-Type: application/json" --request POST --data '{"address":"0xYourEthereumHexAddress"}' 3.95.21.91:3000
    ```

## Public Testnet Node RPC Endpoints

- **Node0**: `54.210.246.165:8545`
- **Node1**: `3.86.104.251:8545`
- **Node2**: `18.204.206.179:8545`

example:

```bash
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}' -H "Content-Type: application/json" 54.210.246.165:8545
```
