How to revoke token approvals

Written by XAUConnect Labs · Reviewed against live product behavior · Updated 16 October 2026

How to revoke token approvals: open the token's allowance for that spender and set it to zero, then confirm the transaction in your wallet.

You pay gas in the chain's native coin. The tokens stay in your wallet. Only the permission disappears. Do this for unlimited approvals you do not remember, especially on Ethereum where old spenders are a common loss. Solana swaps do not leave an ERC-20 allowance behind.

An approval is permission. It is not the swap.

What not to revoke in a panic

If you are mid-trade, revoking the router you are about to use will make the next swap fail until you approve again. Revoke after the trade, or revoke spenders that are not today's router.

Which allowance to clear

Clear unlimited allowances on spenders you do not recognise. Leave the router you are about to use until the swap confirms, or the next transaction will ask for approval again. Why the allowance exists is what a token approval is. This costs gas. It does not return tokens already taken.
