NAMETAG TOKEN

V1.0.0

An ERC721 non-fungible token with the hash of your unique lowercased 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 ask this contract which account the @bob token resides in and will send the payment to that address.

NAMETAG TOKEN

An ERC721 non-fungible token with the hash of your unique lowercased 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!
