Initialize the firmachain

Initialize nodes and designate the moniker name.

firmachaind init <moniker-name> --chain-id <chain-id>

Rename the moniker

Before activating the chain, you can modify the moniker field in the ~/.firmachain/config/config.toml to change the name of the node.

vim .firmachain/config/config.toml

# A custom human readable name for this node
moniker = "<moniker-name>"

Setup minimum gas prices

Modify the minimum gas fee.

sed -i 's/minimum-gas-prices = "0stake"/minimum-gas-prices = "0.01ufct"/g' ~/.firmachain/config/app.toml

Set seeds

FirmaChain discloses information on seed nodes for the purpose of P2P connection.

# Mainnet
sed -i.bak -e "s/^seeds *=.*/seeds = \"[e-mail]:26656,[e-mail]:26656,[e-mail]:26656\"/" ~/.firmachain/config/config.toml

Download genesis.json file

After downloading the mainnet genesis.json file, swap the file with ~/.firmachain/config/genesis.json.

# Mainnet genesis.json
wget https://raw.githubusercontent.com/FirmaChain/mainnet/main/colosseum-1/genesis.json -O ~/.firmachain/config/genesis.json
