Joining Chainsafe's Public Testnet

This document outlines the steps to join the public testnet hosted by Chainsafe.

Steps:

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

git clone https://github.com/cosmos/ethermint
cd ethermint
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;

"7678d52de4a724e468e503a7743664d12a78b5b0@18.204.206.179:26656,c62fadc76b7fa1ab25669b64fdc00c8d8d422bd0@3.86.104.251:26656,5fa7d4550b57298b059d1dd8af01829482e7d097@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

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

Public Testnet Node RPC Endpoints

Node0: 54.210.246.165:8545 Node1: 3.86.104.251:8545 Node2: 18.204.206.179:8545

example:

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