💰 Manage Access

Orders control who can use your iApp and under what conditions. Once your iApp is deployed with iApp Generator, you need to create app orders to make it accessible to users and define your governance rules.

Think of orders as usage contracts - they define pricing, access restrictions, and execution conditions for your application.

What is an Order?

An app order is a signed contract that defines the usage conditions for your iApp:

• Price per execution (in nRLC)
• Number of authorized uses
• Access restrictions (specific users, workerpools)
• TEE configuration (for confidential applications)

TIP

Currently, order management is not yet available in iApp Generator. This guide shows you how to use the iExec SDK CLI to create and manage your app orders.

For complete SDK documentation, check the iExec SDK GitHub repository.

How Orders Work

Here's the simplified process:

1. You create an app order with your conditions (price, restrictions, etc.)
2. You sign the order with your wallet
3. You publish the order on the iExec marketplace
4. Users can discover and execute your iApp according to your conditions
5. You automatically receive payment in RLC for each execution

Deployed iApp + Signed App Order = Application accessible on iExec

App Order Example

Here's an example app order for a sentiment analysis iApp:

{
  "app": "0x123abc...", // Your iApp address
  "appprice": "1000000000", // 1 RLC per execution
  "volume": "100", // 100 authorized uses
  "tag": "0x0000000000000000000000000000000000000000000000000000000000000003", // TEE required
  "datasetrestrict": "0x0000000000000000000000000000000000000000",
  "workerpoolrestrict": "0x0000000000000000000000000000000000000000",
  "requesterrestrict": "0x0000000000000000000000000000000000000000"
}

Creating an App Order from an iApp Generator Project

Step 1: Install the iExec SDK

Since iApp Generator doesn't handle orders yet, you need to use the iExec SDK CLI:

npm

npm install -g iexec

yarn

yarn global add iexec

Verify the installation:

iexec --version
iexec --help

Step 2: Configure your iExec Project

In your iApp Generator project folder, initialize the iExec configuration:

# In your iApp Generator project folder
iexec init --skip-wallet

This creates the necessary configuration files:

• iexec.json - Project configuration
• chain.json - Blockchain configuration

Step 3: Configure your Wallet

If you don't have an iExec wallet yet:

iexec wallet create

Or import an existing wallet:

iexec wallet import <private-key>

iApp Generator Users

If you used iApp Generator, you already have an iexecconfig.json file with a generated private key. You can use this existing private key to initialize your wallet:

# Extract the private key from your `iexecconfig.json`
iexec wallet import <your-private-key-from-iexecconfig>

Check your wallet:

iexec wallet show

Step 4: Create the App Order

Initialize the app order:

iexec order init --app

This adds an apporder section to your iexec.json. Edit the parameters according to your needs:

{
  "apporder": {
    "app": "0xYourAppAddress",
    "appprice": "1000000000",
    "volume": "100",
    "tag": "0x0000000000000000000000000000000000000000000000000000000000000003",
    "datasetrestrict": "0x0000000000000000000000000000000000000000",
    "workerpoolrestrict": "0x0000000000000000000000000000000000000000",
    "requesterrestrict": "0x0000000000000000000000000000000000000000"
  }
}

Step 5: Sign and Publish the Order

Sign your app order with your wallet:

iexec order sign --app

Publish the order on the marketplace:

iexec order publish --app

Your iApp is now accessible according to the conditions you defined!

Managing Orders

View Published Orders

Check active orders for your app:

iexec orderbook app <your-app-address>

Modify an Order

To change conditions, create a new order with new parameters.

Cancel an Order

Remove an order from the marketplace:

iexec order unpublish --app <orderHash>

Completely invalidate an order:

iexec order cancel --app <orderHash>

🛡️ Confidential App (TEE Required)

{
  "appprice": "2000000000",
  "volume": "500",
  "tag": "0x0000000000000000000000000000000000000000000000000000000000000003"
}
