    • "Address Index" is the last value of the Derivation Path (e.g. 44'/394'/0'/0/{address_index}), which used to derive different addresses from the same key based on different number input. You will need to input the same "Address Index" if you want to restore the Ledger wallet address on another device. For the network, three options of "Testnet Croeseid 4", "Mainnet", and "Custom Devnet" are given. Testnet Croeseid 4 is Croeseid testnet which is our Cosmos-based testnet that has been running since October 2020. Mainnet refers to Crypto.org Chain mainnet. Other than these, you can also fill up the custom configuration to your own network. In this demonstration, we will be creating a testnet address and connecting to the current Croeseid Testnet, therefore, we select "Testnet Croeseid 4" as the network option.
