Check current balance for any principal or subaccount
Network Support
Query balances across local, IC, or custom networks
Precision Options

Balance Check Options
Managing Cycle Approvals
Configure spending approvals to enable automated systems or other principals to spend cycles on your behalf:1
Set Spender
Spender Principal: Enter the principal authorized to spend cycles
2
Define Limits
Amount: Set maximum cycles that can be spent
3
Add Context
Memo: Optional memo for transaction tracking
4
Set Expiration
Expires At: Set expiration timestamp for the approval
Approval Configuration Options
Spender Configuration
Spender Configuration
--spender: Principal authorized to spend cycles- Supports both user principals and canister principals
- Validation ensures proper principal format
Amount and Limits
Amount and Limits
--amount: Maximum cycles that can be spent- Support for different cycle units (T, G, M, K)
- Automatic validation against available balance
Tracking and Expiration
Tracking and Expiration
--memo: Optional memo for the approval--expires-at: Expiration timestamp for the approval- Automatic cleanup of expired approvals
Use cycle approvals to enable automated systems or other principals to spend cycles on your behalf within defined limits. This is particularly useful for automated canister management and CI/CD systems.

Best Practices
Balance Management
Balance Management
Optimize your cycle monitoring:
- Regular Monitoring: Use the balance checker to track cycle consumption patterns
- Automated Alerts: Set up monitoring for low cycle balances
- Consumption Analysis: Track usage patterns to predict future needs
- Buffer Maintenance: Keep adequate cycle buffers for operations
Approval Strategy
Approval Strategy
Optimize cycle approvals:
- Strategic Approvals: Use cycle approvals for automated systems with appropriate limits
- Limit Management: Set conservative spending limits for security
- Regular Audits: Review and update approvals regularly
- Expiration Management: Use expiration dates for temporary approvals
Conversion Planning
Conversion Planning
Optimize ICP to cycle conversions:
- Advance Planning: Convert ICP to cycles before critical operations to avoid delays
- Rate Monitoring: Check ICP-to-cycles rates before large conversions
- Batch Conversions: Consider larger, less frequent conversions for efficiency
- Market Timing: Monitor market conditions for optimal conversion timing
Organization & Records
Organization & Records
Optimize cycle organization:
- Subaccount Usage: Use subaccounts for organization by project or purpose
- Transaction Records: Use memos to track the purpose of transfers and conversions
- Documentation: Maintain clear records of cycle operations and purposes
- Testing Protocol: Test operations on local networks before using mainnet
Troubleshooting
Balance Issues
Balance Issues
Common balance problems and solutions:Problem: Balance not updating or showing incorrect amounts
- Click the refresh button to update manually
