How to Revoke Token Approvals and Clean Up Your Wallet

Every DeFi protocol you've used still has permission to touch your tokens. Here's how to find out what you've approved and how to remove the ones that are a liability.

Token approvals don't expire. When you approved Uniswap to spend your USDC two years ago, that approval is still live right now. If a vulnerability is ever discovered in that contract, or if the contract was malicious from the start, your entire approved balance is still at risk.

An active DeFi wallet accumulates a long list of approvals over time. Most of them are from protocols you barely remember โ€” old Uniswap versions, yield farms that closed, random dApps you tried once and never went back to. Each one is still active. Each one is a door that never got locked. Revoking them doesn't take your tokens back, but it closes those doors going forward.

How to run a full approval audit on Revoke.cash

  • 1.Go to revoke.cash
  • 2.Connect the wallet you want to audit (MetaMask, Phantom, or paste an address to audit without connecting)
  • 3.The dashboard shows every active approval โ€” sorted by token, spender, and approved amount
  • 4.Look for unlimited approvals (shown as โˆž or a very large number) from contracts you don't recognize
  • 5.Click Revoke next to any you want to remove โ€” you'll be prompted to sign a small gas transaction
  • 6.Repeat for each wallet you use actively

Revoke.cash supports Ethereum, BSC, Polygon, Arbitrum, Optimism, Base, and most major EVM chains. You can audit any public address without connecting a wallet โ€” useful for checking a cold wallet address before transferring assets into it.

What to prioritize when revoking

You don't need to revoke everything โ€” just reduce your risk surface. Here's what to focus on:

  • โ€”Unlimited approvals for unverified or obscure contracts โ€” these are the highest risk
  • โ€”Any spender contract you don't recognize by address or name
  • โ€”Protocols that have been exploited or shut down โ€” the contract still has permissions
  • โ€”Approvals for large token balances you're actively holding
  • โ€”Old versions of protocols (Uniswap v2 approvals when you now only use v3)

Going forward: approve less, revoke less

The cleanest approach is to approve less in the first place:

  • โ€”Set a custom approval amount equal to what you're actually spending โ€” not unlimited
  • โ€”Use protocols that support permit2 (like Uniswap) โ€” permit signatures expire and don't require on-chain approvals
  • โ€”Keep your main wallet separate from your DeFi wallet โ€” don't hold your long-term holdings in the wallet you use to interact with dApps

Frequently asked questions

How do I revoke token approvals?

Go to revoke.cash, connect your wallet, and click Revoke next to any approval you want to remove. Each revocation is a small on-chain transaction. The whole audit takes 5โ€“10 minutes for most wallets.

How often should I revoke token approvals?

Monthly for active DeFi users. Immediately after any security scare โ€” a protocol you used was hacked, you clicked a suspicious link, or you noticed unexpected activity. Do it on a schedule, not just after something scares you.

Does revoking a token approval affect my DeFi positions?

No โ€” revoking only affects future transactions. Existing positions, staked tokens, and liquidity are unaffected. If you use that protocol again later, you'll just re-approve when prompted.
