How to revoke a token approval

The first time you swap or add liquidity to a pool, you must approve the token to be swapped. This gives the Uniswap Protocol permission to swap that token from your wallet.

Sometimes, token approvals need to be revoked. Here are a few reasons why:

• Your wallet has been compromised
• To change the amount of a token that has been approved
• To reduce the risk of stolen funds/tokens

If you revoke a token approval, you will have to approve the token again the next time you attempt to swap on Uniswap.

How to revoke a token approval:

1. Go to the “approval checker” section of the block explorer for the network you're on

   • Ethererum
   • Unichain
   • BNB Smart Chain
   • Polygon
   • Optimism
   • Arbitrum
   • Base
   • Celo
   • Avalanche
     
     

2. Connect your wallet
   
   

3. Revoke the token approval from any address that you wish

   Please note that revoking a token does require network costs and this process is different from disconnecting from a dapp.
