Receiving Grins

Let's see how you can receive your first grins.

Interactive Transactions

The nature of Mimblewimble protocol means that the sender & receiver need to interact with one another, in some way or another, in order to form transactions.

The first step is to generate an address:

grin-wallet address

It is not an on-chain address, as it's only used for wallet-to-wallet communication.


Give it to the sender.

To understand what comes next, you should know there are two primary ways to interact with the other party: Tor and Slatepack. A Tor connection is attempted first, but if it isn't accessible (counterparty offline, or either party doesn't have Tor service installed), then Slatepack method is automatically chosen.


All you need to do is type:

grin-wallet listen

Done! This sets up your wallet to listen for incoming connections through Tor. Just let the sender know that your wallet is ready. You can type grin-wallet info to check your wallet balance.


Slatepacks are encoded text messages used to transfer the data required to form a transaction, and are an alternative to a hands-off method such as Tor. The messages are easily copy-pasted and can be transferred in any communication channel imaginable: email, forum, social media, chat, letter, carrier pigeon etc.

The text you receive from the sender should look like this:

ENDSLATEPACK.

Your next step would be to type:

grin-wallet receive

Then enter the message you were sent into the prompt.

Next, your own wallet will output a beautiful Slatepack message as well:


Copy and send it to the other party, and that's it, you've completed your role!

It's now in the hands of the sender to finalize and post the transaction to the network. You can tell when it's accepted by the chain by typing grin-wallet info and seeing if there's an amount waiting for confirmation.
