JoiningTestnet

This document outlines the steps to join the public testnet

Steps

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

   git clone https://github.com/tharsis/ethermint
   cd ethermint
   git checkout v0.4.1
   make install
   

2. Create an Ethermint account

   ethermintcli keys add <keyname>
   

3. Copy genesis file

   Follow this link 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

   "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

   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

   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:

   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

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