Run a Node

Run a local node and start the REST and JSON-RPC clients {synopsis}

Clone and build Ethermint:

git clone <https://github.com/ChainSafe/ethermint>
cd ethermint
make install

Run the local testnet node with faucet enabled:

::: warning The script below will remove any pre-existing binaries installed :::

./init.sh

In another terminal window or tab, run the Ethereum JSON-RPC server as well as the SDK REST server:

emintcli rest-server --laddr "tcp://localhost:8545" --unlock-key mykey --chain-id 8

Key Management

To run a node with the same key every time: replace emintcli keys add $KEY in ./init.sh with:

echo "your mnemonic here" | emintcli keys add ethermintkey --recover

::: tip Ethermint currently only supports 24 word mnemonics. :::

You can generate a new key/mnemonic with

emintcli keys add <mykey>

To export your ethermint key as an ethereum private key (for use with Metamask for example):

emintcli keys unsafe-export-eth-key <mykey>

Requesting tokens though the testnet faucet

Once the ethermint daemon is up and running, you can request tokens to your address using the faucet module:

# query your initial balance
emintcli q bank balances $(emintcli keys show <mykey> -a)  

# send a tx to request tokens to your account address
emintcli tx faucet request 100photon --from <mykey>

# query your balance after the request
emintcli q bank balances $(emintcli keys show <mykey> -a)

You can also check to total amount funded by the faucet and the total supply of the chain via:

# total amount funded by the faucet
emintcli q faucet funded

# total supply
emintcli q supply total
