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Grants cannot be withdrawn - they're only for callback fees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 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.
Navigate to "My Subscription".
Click "Withdraw Funds" from the Menu.
