The keygen command (chr keygen) generates a public and private key pair. By default, the keys are generated with default key id chromia_key and saved in the .chromia folder as chromia_key.pubkey and chromia_key.

  • Set your key id --key-id=<key_id> .

  • To use a key pair by its key ID, set the property = <key_id> in your configuration file.

  • To recover a key pair from a mnemonic, pass in the mnemonic with --mnemonic "march aspect pizza treat ...".
