Update Validator Commission

Below are detailed instructions for creating and running a Node.js script to update the validator commission on the Root Network. Below are some important things to keep in mind:

• Commission values are in parts per billion (ppb)
• Example conversions:
  • 0.75% = 7,500,000 ppb
  • 10% = 100,000,000 ppb
• Double-check your commission values before submitting
• Keep your validator keys secure

​

Using Node.js Script

1. Create a new Node.js project and install dependencies:

npm install @polkadot/api @polkadot/keyring @polkadot/util @therootnetwork/api

2. Create a script file (e.g., update-commission.js) with the code below:

const { Keyring } = require("@polkadot/keyring");
const { hexToU8a } = require("@polkadot/util");
const { ApiPromise } = require("@polkadot/api");
const { getApiOptions, getPublicProvider } = require("@therootnetwork/api");

async function updateCommission(validatorKey, commissionPPB) {
    try {
        // Initialize API
        const api = await ApiPromise.create({
            ...getApiOptions(),
            ...getPublicProvider("root"),
        });

        // Initialize keyring
        const keyring = new Keyring({ type: "ethereum" });
        const validator = keyring.addFromSeed(hexToU8a(validatorKey));

        // Create commission update call
        const call = api.tx.staking.validate({
            commission: commissionPPB,
            blocked: false
        });

        const setCommission = api.tx.futurepass.proxyExtrinsic(
            "0xfffFfFFf00000000000000000000000000040F95",
            call
        );

        // Send transaction
        const txHash = await setCommission.signAndSend(validator);
        console.log(`Transaction submitted with hash: ${txHash}`);

        // Wait for confirmation
        await new Promise(resolve => setTimeout(resolve, 5000));
        console.log("Please verify the commission update on the Root Network Portal");

    } catch (error) {
        console.error("Error updating commission:", error);
    }
}

// Example usage (replace with your values)
// updateCommission('YOUR_VALIDATOR_KEY', 7500000); // For 0.75% commission

Using the Root Network Portal

Option 1 - Update Using Extrinsics

1. Go to the Root Network Portal and sign in with your Metamask wallet. Ensure your accounts and Root Balances are visible under the Accounts section. If not, troubleshoot your Metamask connection.

2. Navigate to the Extrinsics page and set up the commission update call like so:
   • In the first dropdown, select futurepass
   • Select proxyExtrinsic(futurepass, call)
   • Under the FuturePass account, verify it shows: FFFF..0F95
   • For the call selection:
     • Select staking
     • Choose validate(prefs)
     • Enter your commission value in ppb format (e.g., 7500000 for 0.75%)
     • Set blocked to “No”

3. Review the encoded call data and hash that appear at the bottom of the form.
4. Click Submit Transaction to proceed with the update.
5. Sign the transaction with MetaMask when prompted.
6. Wait for confirmation of the transaction.

​

Option 2 - Change Validator Preferences

1. Go to the Portal Extrinsics page and choose Network > Staking from the drop-down menu.
2. Select the Accounts tab.
3. Locate your stash account option and choose Change validator preferences. validator-commission

4. On the Set Validator Preferences page, enter your commission value in the Reward Commission Percentage field. Example: For 0.75%, enter 0.75.

5. Click Validate to confirm and submit the request.
