It would be useful to have, in addition to the TRANSFER event, a TRANSFER_TO_ME event. This would be similar to the DONATE event, except that it would be usable by non-creators. (Alternately - the DONATE event could be used, but allowed for non-creators.) The information included would be the same as for DONATE and TRANSFER, but would always include the "creator approved" data - so the recipient would always be able to determine who has sent the coin. It is important to note that this would provide no more data than is already available in a user's portfolio transactions. It would just provide an automated way to do so. Use cases for this allow for a "Vending machine" (or "Jukebox" or "Arcade game") model, where a person could deposit coin first and then take some action based on how much has been deposited. The advantage of this over an OAuth "initiate transfer" is that it does not need to be initiated through a website or a web interface - it could be initiated from the Rally website or through something like the discord bot.
