snubb --helpThe terminal UI supports keyboard navigation:
- n/p: Navigate through the approval list
- >/<: Navigate between pages
- Enter: Toggle detailed view for an approval
- h: Show help screen
- q: Quit the application
When an approval is selected, the full token and spender addresses are shown in the details panel, allowing you to copy the complete addresses for use in blockchain explorers.
The tool scans for two types of events:
- Approval events - When you authorize a contract/address to spend your tokens
- Transfer events - When tokens move from your wallet (potentially using those approvals)
The results show:
- Token Address - The contract address of the token
- Spender - The address authorized to spend your tokens
- Approved - The amount you've approved for spending
- Used - How much the spender has already used
- Remaining - The current remaining approval (what you're still exposed to)
- Revoke unnecessary approvals, especially those with unlimited amounts
- Use token allowance services like revoke.cash or etherscan's token approval tool
- Be cautious with unlimited approvals (∞) as they represent unlimited access to that token
