Create a Token Network

To be able to make token payments in Raiden you first need to join the network of the token you're interested in making payments with.

Check if the token is registered

Before you can join a token network you need to determine whether the token has been registered and a network for the token has been created.

We can verify this by making a query to the tokens endpoint.

curl -i http://localhost:5001/api/v1/tokens

If the address exists in the list returned by the response you can go ahead and open a channel in that token network.

If the address is not in the list you'll have to register the token before you can open a channel.

Register a new token

Registering a new token is as simple as calling the tokens endpoint with a PUT request while providing the address of the token you want to register as a path parameter.

curl -i -X PUT http://localhost:5001/api/v1/tokens/0x9aBa529db3FF2D8409A1da4C9eB148879b046700 \
-H 'Content-Type: application/json'

If the call is successful the response will return a new address of the now newly created token network.

HTTP:/1.1 201 CREATED
Content-Type: application/json
{
"token_network_address": "0xC4F8393fb7971E8B299bC1b302F85BfFB3a1275a"
}

Because this token was just registered by you, no one else will be connected to its network and you'll have to open a channel with another Raiden node.

Payment channels between parties are opened in token networks.

Registering a new token is currently only relevant on the testnets. The tokens allowed on the mainnet for the Alderaan release are DAI and W-ETH. At some point in future, you will be able to register new token networks for the Ethereum mainnet, too.
