An ERC721 non-fungible token with the hash of your unique Alias imprinted upon it.
Register your handle by minting a new token with that handle. Then, others can send Ethereum Assets directly to you handle (not your address) by sending it to the account which holds that token!
For example, one could register the handle @bob and then alice can use wallet services to send payments to @bob. The wallet will be ask this contract which account the @bob token resides in and will send the payment there!
