Initialize the firmachain ​

Initialize nodes and designate the moniker name.

bash
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.

bash
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.

bash
sed -i -E 's/minimum-gas-prices = ".*"/minimum-gas-prices = "0.01ufct"/' ~/.firmachain/config/app.toml

Set seeds ​

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

bash
# Mainnet
sed -i.bak -e "s/^seeds *=.*/seeds = \"f89dcc15241e30323ae6f491011779d53f9a5487@mainnet-seed1.firmachain.dev:26656,04cce0da4cf5ceb5ffc04d158faddfc5dc419154@mainnet-seed2.firmachain.dev:26656\"/" ~/.firmachain/config/config.toml

Download genesis.json file ​
