 ## Managing local node accounts
 
-By default local Cudos node starts with 10 predefined accounts funded with `acudos`. You can set how many additional random accounts to load when starting a local node in `blast.config.js` under `additionalAccounts`. In `customAccountBalances` you can set the amount of tokens that these additional accounts will be funded with. Another way to manage custom accounts is through `blast keys` command.
