Deposit and Withdraw Funds

After adding contracts, you need to ensure your subscription has sufficient funds to pay for callback gas fees. You can deposit funds through the web interface or using on-chain functions.

Understanding Your Grant

Remember, you have a grant from Supra that's used before your deposited funds: This is displayed in UI.

How Grants Work:

Callback fees are deducted from your grant first
Once grant is exhausted, fees come from your deposited funds
Grants cannot be withdrawn - they're only for callback fees
Your deposited funds remain untouched until grant is fully used

Deposit Funds

- Go to supra.com/data/dvrf

- Ensure balance is above minimum threshold
- Monitor deposit balance alerts.

Managing Grants

// Check remaining grant
let remaining_grant = deposit::get_client_remaining_grant(client_address);

// Check total grant received
let total_grant = deposit::get_client_total_grant(client_address);

Deposit funds

movedeposit::deposit_fund_v2(
    sender: &signer, 
    client_address: address, 
    deposit_amount: u64
)

Parameters:

sender - The signer depositing the funds (can be any address)
client_address - The whitelisted wallet address receiving the deposit
deposit_amount - Amount to deposit (in the smallest unit of the native token)

Key Features:

✅ Anyone can deposit on behalf of a client
✅ Useful for team members or automated top-up services.

Checking Your Balance

Before depositing, check your current balance and minimum balance requirements:

// Check total deposited funds
let total_balance = deposit::check_client_fund(client_address);

// Check minimum balance requirement
let min_balance = deposit::check_min_balance_client_v2(client_address);000000000000000000

Best Practices

Deposit Strategy

Maintain Buffer: Keep 3-5x your minimum balance for uninterrupted service.

5x minimum = Comfortable buffer for high-volume applications
3x minimum = Acceptable for moderate usage
Below 2x minimum = Risky, may block requests soon

Regular Monitoring: Check your balance periodically, especially during high-usage periods

Automated Top-ups: Consider implementing an automated deposit script that monitors your balance

Multiple Depositors: Designate team members or services that can deposit on your behalf for redundancy

Withdraw Funds

You can withdraw excess funds from your subscription when needed via UI or via onchain functions.

Important: You cannot withdraw funds while you have pending random number requests

Navigate to "My Subscription".
Click "Withdraw Funds" from the Menu.
Enter withdrawal amount.
Confirm transaction in your wallet.

deposit::withdraw_fund(
    sender: &signer, 
    withdraw_amount: u64
)

Parameters:

sender - Your signer (must be the whitelisted wallet owner)
withdraw_amount - Amount to withdraw (in smallest unit)

Important Restrictions:

❌ Only the whitelisted wallet owner can withdraw their own funds.
❌ Grants cannot be withdrawn - only deposited funds.
