Revoke Approvals
When you trade ERC-20 tokens on decentralized exchanges, you need to grant permission (called an "approval") for the exchange's smart contract to spend your tokens. While this is necessary for trading, these approvals remain active even after your trades are complete.
For security reasons, it's good practice to periodically review and revoke unnecessary token approvals. This prevents old approvals from being exploited if a smart contract is compromised or if you no longer trust a particular protocol.
Why Revoke Approvals?
Security Benefits:
Reduces your attack surface by limiting which contracts can access your tokens
Protects against potential smart contract vulnerabilities
Gives you better control over your wallet's security posture
When to Revoke:
After you're done trading a particular token pair
When you no longer plan to use a specific DEX or protocol
If you've given unlimited approvals and want to switch to exact amounts
As part of regular wallet hygiene and security maintenance
Using the Revoke Tool
We offer an approval revoke tool built into our dapp which lets you quickly and easily manage the security of your wallet and its tokens.
How to Use:
Connect your wallet to the LiquidSwap interface
Navigate to the revoke approvals section
Review the list of active approvals for your wallet
Select the approvals you want to revoke
Confirm the revoke transactions in your wallet
What You'll See:
Token name and contract address
Approved amount (may show "Unlimited" for maximum approvals)
The protocol or contract that has approval
Current allowance remaining
Each revoke action requires a separate transaction and will cost a small amount of gas. However, this is a worthwhile investment in your wallet's security.
Important: Revoking an approval means you'll need to re-approve that token the next time you want to trade it. Only revoke approvals you're sure you won't need in the near future.
