You can manage your token approvals manually. Open Etherscan, navigate to the token approval checker, find your wallet, scroll through the list, identify the risky ones, submit individual revocation transactions, pay gas for each one, and repeat on every chain you’ve ever used. It works. It’s also the digital equivalent of doing your taxes with a pencil and paper — technically possible, practically unsustainable.
The Manual Approach
The DIY security workflow looks like this:
- Open a block explorer for each chain you use
- Navigate to the token approval page for your wallet
- Read through the list of active approvals
- Research each spender address to determine if it’s legitimate
- Decide which approvals to revoke based on your own risk assessment
- Submit individual revocation transactions, one at a time
- Pay separate gas fees for each revocation
- Repeat for every chain. Remember to come back and do it again next month.
This works for one wallet on one chain if you’re disciplined. It breaks down the moment you have multiple wallets, multiple chains, or a life that prevents you from doing a manual audit every month.
What Tooling Adds
| Capability | Manual (Etherscan) | Security Tool |
|---|---|---|
| Multi-chain scan | One chain at a time | All chains in one pass |
| Risk scoring | Your judgment | Automated scoring against threat data |
| Batch revocation | One at a time | Multiple in one transaction, 50–70% gas savings |
| Continuous monitoring | Remember to check | Automatic alerts when risk changes |
| Historical tracking | None | Timeline of approval changes over time |
| Time to audit | 30–60 minutes per chain | Under 60 seconds, all chains |
When Manual Is Enough
If you have one wallet, on one chain, with fewer than ten active approvals, and you check monthly — manual works. Most people don’t fit that description.
When You Need Tooling
The moment any of these are true, manual security becomes a liability:
- You use more than one chain
- You have more than one wallet
- You interact with new dApps regularly
- You manage funds for others (DAO, treasury, team)
- You don’t audit monthly (be honest)
The question isn’t whether a tool is better than manual — it obviously is. The question is whether the risk you’re carrying justifies the effort of managing it by hand. For most active DeFi users, it doesn’t.
