ethermint部署智能合约

安装ethermint

1. 获取ethermint源码，并安装

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

cd ethermint 

make install

• 检查是否安装成

cd $GOPATH/bin

ll ethermint*

ethermintd

ethermin俄cli

• 将GOPATH/bin加入到PATH环境变量

export PATH=$PATH:$GOPATH/bin

启动ethermintd

• 启动脚本

#!/bin/bash

KEY="mykey"
CHAINID="ethermint-1"
MONIKER="localtestnet"

# remove existing daemon and client
rm -rf ~/.ethermint*

make install

ethermintcli config keyring-backend test

# Set up config for CLI
ethermintcli config chain-id $CHAINID
ethermintcli config output json
ethermintcli config indent true
ethermintcli config trust-node true

# if $KEY exists it should be deleted
ethermintcli keys add $KEY

# Set moniker and chain-id for Ethermint (Moniker can be anything, chain-id must be an integer)
ethermintd init $MONIKER --chain-id $CHAINID

# Change parameter token denominations to aphoton
cat $HOME/.ethermintd/config/genesis.json | jq '.app_state["staking"]["params"]["bond_denom"]="aphoton"' > $HOME/.ethermintd/config/tmp_genesis.json && mv $HOME/.ethermintd/config/tmp_genesis.json $HOME/.ethermintd/config/genesis.json

# Allocate genesis accounts (cosmos formatted addresses)
ethermintd add-genesis-account $(ethermintcli keys show $KEY -a) 100000000000000000000aphoton

# Sign genesis transaction
ethermintd gentx --name $KEY --amount=1000000000000000000aphoton --keyring-backend test

# Collect genesis tx
ethermintd collect-gentxs

echo -e '\n\ntestnet faucet enabled'
echo -e 'to transfer tokens to your account address use:'
echo -e "ethermintcli tx faucet request 100aphoton --from $KEY\n"


# Run this to ensure everything worked and that the genesis file is setup correctly
ethermintd validate-genesis

# Command to run the rest server in a different terminal/window
echo -e '\nrun the following command in a different terminal/window to run the REST server and JSON-RPC:'
echo -e "ethermintcli rest-server --laddr \"tcp://localhost:8545\" --unlock-key $KEY --chain-id $CHAINID --trace\n"

# Start the node (remove the --pruning=nothing flag if historical queries are not needed)
ethermintd start --pruning=nothing --rpc.unsafe --log_level "main:info,state:info,mempool:info" --trace
