Your GRAYLL App account "Federation Address" is your "Payment Alias", it can be used instead of your GRAYLL App account address (Public Key). Your federation address starts with "grayll@grayll.io*" and is easily recognizable for you and people that would like to send you GRX (GRAYLL) or XLM (Stellar Lumens). Your federation address is shown in your GRAYLL App account wallet and can be updated in your user settings. Public Keys start with the letter "G" - for example:
GY4S3FML4S25HDAMJYZJYAC3CKLDWV2Z6YPV3IZXOSHSQKNSKUNQFXYZ
