Yagna management for requestors
In this article, we present commands related to the daily management of your Yagna.
- Checking the wallet address
- Enabling mainnet accounts
- Checking the status of the wallet
- Getting test funds
- Generating the unique app-keys
This example has been designed to work with the following environments:
- OS X 10.14+, Ubuntu 20.04 or Windows
Yagna service is installed and running.
Your Golem wallet address
Golem's wallet is automatically initialized for you the first time you start your
yagna service and thus, an address associated with it is also generated automatically.
To have any kind of funds transferred to your Golem's wallet, you'll need its address. You may obtain it using the
yagna id show
The value described as
nodeId in the output is the Ethereum address of your Golem node and it's also the address of its wallet. Note it down so you can use it to supply your node with funds.
Enable the mainnet account
In the current version of the requestor's set-up, the service is configured to use the Goerli testnet by default. Also, all accounts are initialized in the receiver mode by default so you need to enable them as a sender (that's the reason we're adding the
--sender flag below).
To enable the service to use the mainnet, you'll need to instruct it to use a command appropriate to your desired mainnet payment platform.
yagna payment init --sender --network=polygon --driver=erc20
Again, unless you have good reasons not to, we recommend using Polygon for the lowest transaction fees.
The initialization must be performed after every restart of the
Checking the status of your accounts
Depending on whether you're mainly running a provider node or a requestor one, your default network (blockchain) may be different.
Because of that, when you run
yagna payment status to verify the state of your payment account and the amount of GLM tokens you have at your disposal, you may need to add the specific
driver parameters to point to the network/driver combination that you're interested in.
In the context of running Golem on mainnet, here are the commands for each of the supported mainnet platforms:
yagna payment status --network=polygon --driver=erc20
Sending test funds to your account
You can top up your wallet with test GLMs by running:
yagna payment fund
Golem will transfer test tokens from our custom faucet (a service that transfers test tokens to an address that asks for them).
Generating the app key
With the service running, enter the service's directory using another shell and generate the yagna app key that will be used by your requestor agent to access yagna's REST API. Note that the
requestor in the command is a tag of the key.
yagna app-key create requestor
This should produce a 32-character-long hexadecimal app key that you need to note down as it will be needed to run the requestor agent.
If you intend to expose your yagna service's REST API port to the outside world (which we strongly discourage), you should absolutely ensure that you keep this key secret, as anyone with access to the key and the port will have complete control over your service.
In case you lose your app key, you can retrieve it with:
yagna app-key list
the value in the key column is the key you need.
