Account Management

Metadata

• Category: compute
• SDK: @0glabs/0g-serving-broker ^0.6.5, ethers ^6.13.0
• Activation Triggers: "deposit", "transfer funds", "refund", "check balance", "account balance"

Purpose

Manage funds across the 0G Compute Network's dual-account system: Main Account (receives deposits) and Provider Sub-Accounts (one per provider, funds locked for that provider's services).

Prerequisites

• Node.js >= 22
• @0glabs/0g-serving-broker and ethers installed
• Wallet with 0G tokens
• .env with PRIVATE_KEY, RPC_URL

Quick Workflow

1. Deposit from wallet to Main Account
2. Transfer from Main Account to Provider Sub-Account
3. Use services (fees auto-deducted from sub-account)
4. Request refund (24-hour lock period)
5. Complete refund after lock expires
6. Withdraw from Main Account to wallet

Fund Flow

Your Wallet
    | deposit
    v
Main Account
    | transfer-fund
    v
Provider Sub-Accounts (one per provider)
    | service usage (auto-deducted)
    | retrieve-fund (24h lock)
    v
Main Account
    | refund

Your Wallet

Core Rules

ALWAYS

• Check balance before making inference requests
• Transfer funds to provider sub-account before using their services
• Wait 24 hours between refund request and completion
• Keep buffer in sub-accounts for uninterrupted service
• Acknowledge provider before first use (acknowledgeProviderSigner)
• Use correct processResponse() param order: (providerAddress, chatID, usageData)
• Extract ChatID from ZG-Res-Key header first, body as fallback (chatbot only)

NEVER

• Initiate refund during active fine-tuning jobs
• Lock all funds in sub-accounts (keep Main Account balance)
• Forget the 24-hour lock period for refunds
• Hardcode private keys
• Use ethers v5 syntax

Code Examples

Check Balance

import { ethers } from 'ethers';
import { createZGComputeNetworkBroker } from '@0glabs/0g-serving-broker';
import 'dotenv/config';

async function checkBalance() {
  const provider = new ethers.JsonRpcProvider(process.env.RPC_URL);
  const wallet = new ethers.Wallet(process.env.PRIVATE_KEY!, provider);
  const broker = await createZGComputeNetworkBroker(wallet);

  // getLedger() returns a tuple array: [address, totalBalance, availableBalance, ...]
  const account = await broker.ledger.getLedger();

  console.log(`Address: ${account[0]}`);
  console.log(`Total Balance: ${ethers.formatEther(account[1])} 0G`);
  console.log(`Available: ${ethers.formatEther(account[2])} 0G`);

  return account;
}

Deposit and Transfer

async function fundProvider(providerAddress: string, amount: number) {
  const provider = new ethers.JsonRpcProvider(process.env.RPC_URL);
  const wallet = new ethers.Wallet(process.env.PRIVATE_KEY!, provider);
  const broker = await createZGComputeNetworkBroker(wallet);

  // Deposit to Main Account
  await broker.ledger.depositFund(amount);
  console.log(`Deposited ${amount} 0G to Main Account`);

  // Transfer to provider sub-account
  const transferAmount = ethers.parseEther(String(amount));
  await broker.ledger.transferFund(providerAddress, 'inference', transferAmount);
  console.log(`Transferred ${amount} 0G to provider ${providerAddress}`);
}

Check Sub-Account

async function checkSubAccount(providerAddress: string) {
  const provider = new ethers.JsonRpcProvider(process.env.RPC_URL);
  const wallet = new ethers.Wallet(process.env.PRIVATE_KEY!, provider);
  const broker = await createZGComputeNetworkBroker(wallet);

  // getAccountWithDetail() returns [subAccountTuple, refundsArray]
  // subAccount tuple: [0]=user, [1]=provider, [2]=balance, [3]=pendingRefund, ...
  const [subAccount, refunds] = await broker.inference.getAccountWithDetail(providerAddress);
  console.log(`Sub-account user: ${subAccount[0]}`);
  console.log(`Sub-account provider: ${subAccount[1]}`);
  console.log(`Sub-account balance: ${ethers.formatEther(subAccount[2])} 0G`);

  if (refunds.length > 0) {
    refunds.forEach((refund: any, i: number) => {
      console.log(`Pending refund ${i + 1}:`, refund);
    });
  }
}

Request Refund (Two-Step)

async function requestRefund() {
  const provider = new ethers.JsonRpcProvider(process.env.RPC_URL);
  const wallet = new ethers.Wallet(process.env.PRIVATE_KEY!, provider);
  const broker = await createZGComputeNetworkBroker(wallet);

  // Step 1: Initiate refund (starts 24h lock)
  await broker.ledger.retrieveFund('inference');
  console.log('Refund requested — 24h lock period started');

  // Step 2: After 24 hours, complete the refund
  // await broker.ledger.retrieveFund('inference');
  // console.log('Refund completed — funds returned to Main Account');
}

Withdraw to Wallet

async function withdrawToWallet(amount: number) {
  const provider = new ethers.JsonRpcProvider(process.env.RPC_URL);
  const wallet = new ethers.Wallet(process.env.PRIVATE_KEY!, provider);
  const broker = await createZGComputeNetworkBroker(wallet);

  await broker.ledger.refund(amount);
  console.log(`Withdrew ${amount} 0G to wallet`);
}

Complete Account Setup

async function setupForProvider(providerAddress: string) {
  const provider = new ethers.JsonRpcProvider(process.env.RPC_URL);
  const wallet = new ethers.Wallet(process.env.PRIVATE_KEY!, provider);
  const broker = await createZGComputeNetworkBroker(wallet);

  // 1. Check current balance (tuple: [0]=addr, [1]=total, [2]=available)
  const account = await broker.ledger.getLedger();
  const available = parseFloat(ethers.formatEther(account[2]));
  console.log(`Available balance: ${available} 0G`);

  // 2. Deposit if needed
  if (available < 5) {
    await broker.ledger.depositFund(10);
    console.log('Deposited 10 0G');
  }

  // 3. Transfer to provider
  await broker.ledger.transferFund(providerAddress, 'inference', ethers.parseEther('5'));
  console.log('Transferred 5 0G to provider');

  // 4. Acknowledge provider
  await broker.inference.acknowledgeProviderSigner(providerAddress);
  console.log('Provider acknowledged');

  console.log('Account setup complete — ready for inference');
}

Error Handling

async function safeFundProvider(providerAddress: string, amount: number) {
  const provider = new ethers.JsonRpcProvider(process.env.RPC_URL);
  const wallet = new ethers.Wallet(process.env.PRIVATE_KEY!, provider);
  const broker = await createZGComputeNetworkBroker(wallet);

  try {
    // Tuple: [0]=address, [1]=totalBalance, [2]=availableBalance
    const account = await broker.ledger.getLedger();
    const available = parseFloat(ethers.formatEther(account[2]));

    if (available < amount) {
      const depositNeeded = amount - available + 1; // +1 buffer
      console.log(`Insufficient balance. Depositing ${depositNeeded} 0G...`);
      await broker.ledger.depositFund(depositNeeded);
    }

    await broker.ledger.transferFund(
      providerAddress,
      'inference',
      ethers.parseEther(String(amount)),
    );
    console.log(`Successfully funded provider with ${amount} 0G`);
  } catch (error) {
    console.error('Funding failed:', error);
    throw error;
  }
}

CLI Commands Reference

| Action | CLI Command | | ----------------- | ----------------------------------------------------------- | | Setup network | 0g-compute-cli setup-network | | Login | 0g-compute-cli login | | Deposit | 0g-compute-cli deposit --amount 10 | | Check balance | 0g-compute-cli get-account | | Check sub-account | 0g-compute-cli get-sub-account --provider <ADDR> | | Transfer | 0g-compute-cli transfer-fund --provider <ADDR> --amount 5 | | Refund (2-step) | 0g-compute-cli retrieve-fund | | Withdraw | 0g-compute-cli refund --amount 5 |

Anti-Patterns

// BAD: Not checking balance before operations
await broker.inference.getRequestHeaders(providerAddress);
// May fail with "insufficient balance"

// BAD: Trying to complete refund immediately
await broker.ledger.retrieveFund('inference'); // Start lock
await broker.ledger.retrieveFund('inference'); // Won't work — 24h lock!

// BAD: Locking all funds in one provider
await broker.ledger.transferFund(addr, 'inference', entireBalance);
// No flexibility to use other providers

// BAD: Hardcoding private keys
const wallet = new ethers.Wallet('0xabc123...', provider); // NEVER do this

// BAD: ethers v5 syntax
const provider = new ethers.providers.JsonRpcProvider(url); // v5!

Common Errors & Fixes

| Error | Cause | Fix | | --------------------------------- | -------------------- | ----------------------------------- | | Insufficient balance | Main account empty | broker.ledger.depositFund(amount) | | Not enough funds in sub-account | Sub-account empty | broker.ledger.transferFund() | | Refund still locked | 24h lock not expired | Wait for lock period | | Provider not acknowledged | First-time provider | acknowledgeProviderSigner() |
