To revoke crypto wallet permissions, first identify what you granted: a website connection and an on-chain token approval are separate. Reviewing both on the correct network can help limit specific access granted to a dapp, but it can’t undo a transaction or secure a compromised device.
TL;DR
- Disconnecting a dapp doesn’t automatically revoke its token approvals.
- Check approvals on each network, then submit a revocation transaction for permissions you no longer need.
- Revoking an approval costs gas, and a dapp may request a new approval if you use it again.
What it means to revoke crypto wallet permissions
A wallet connection lets a site send requests to your wallet while it’s connected. You may be asked to approve transactions separately. A token approval instead lets a specific smart contract spend a token or manage an NFT under the approval’s terms. MetaMask’s guide to managing dapp permissions explains that disconnecting a site doesn’t remove an on-chain token approval.
If you stop using a marketplace, game, or decentralized finance app, its connection can be removed while an old approval remains on the blockchain. To review these permissions, check both your wallet’s connected-site list and its token or NFT approvals.
ERC-20 approvals commonly let a named spender use a specified token amount. Revoke.cash explains that revocation generally means submitting a new approval for that spender with the allowance set to zero. NFT permissions can be broader: MetaMask notes that ERC-721 and ERC-1155 setApprovalForAll permissions can let another address manage all tokens associated with a collection contract.
How to revoke crypto wallet permissions safely
Wallet labels and screens vary, but the process is similar. Use a permission checker or wallet feature you trust, and confirm the network and spender before signing.
- Open the right wallet and network. Choose the account that used the dapp, then select the network where the approval was made. Revoke.cash says approvals are specific to a token and network, and its checker supports more than 80 networks. An approval on one chain doesn’t automatically apply to another.
- Review connected sites separately. In your wallet’s connected-app or site-permissions settings, disconnect sites you no longer use. This removes the connection, not the on-chain allowance.
- Inspect approvals. Check the token or NFT, spender address, and approved amount or collection-wide permission. Don’t sign just because a site labels an approval old or risky. Verify the details in your wallet.
- Submit the revocation. Select the permission and review the transaction in your wallet. Revoking is an on-chain transaction that requires gas on that network. Confirm only if the details match the action you intend to take.
- Check the result. Refresh the checker or wallet after confirmation. If you use several networks or accounts, review each separately.
As of November 2, 2026, MetaMask says its Portfolio Spending Caps tool supports Ethereum Mainnet, Polygon, BNB Chain, Optimism, and Base. Users select a cap and submit a revocation transaction in their wallet. Controls vary by wallet, network, and token type, so one dashboard may not cover every approval.
How to revoke crypto wallet permissions for NFTs
For an NFT, check whether permission applies to one item or an entire collection. A collection-wide setApprovalForAll grant can be broader than approval for a single NFT. Before revoking, confirm that the contract and collection shown in the wallet or checker are ones you recognize.
What revoking does, and what it doesn’t
Revocation removes or changes a specific approval, so the spender can no longer use the token under that approval. It doesn’t return transferred tokens, cancel a completed transaction, or remove funds deposited in a protocol. Revoke.cash’s FAQ says revoking approvals doesn’t affect tokens already deposited or staked, though you may need to approve the token again before adding more.
Revoking an approval also can’t protect a wallet if its recovery phrase or device has been compromised. Approval controls address specific permissions, not every security risk. A permission review alone can’t establish that a wallet, device, or dapp is secure.
Risks and limits to keep in mind
A revocation transaction can cost gas, and network fees vary. Rushing can also create risk if you haven’t checked the contract, chain, or action in the wallet prompt. Be careful with links and tools: fraudulent sites can imitate wallet services and try to get users to sign harmful transactions.
Approvals have been involved in real losses. Revoke.cash dates an exploit involving Magic Eden’s Limit Break Payment Processor to September 24, 2026, and reports about $3.4 million lost. It advises users who approved Payment Processor V2 or V3 to revoke those approvals. This doesn’t mean every approval is unsafe, but it shows why permission reviews can matter. Crypto transactions carry risks including theft, smart contract failure, and loss of funds.
Pros and cons of revoking approvals
| Potential benefit | Trade-off or limit |
|---|---|
| Removes a specific spender’s active allowance | Requires an on-chain transaction and gas |
| Can reduce exposure from permissions you no longer need | Doesn’t recover funds already moved |
| Lets you review token and NFT access by network | You may need to approve again to use a service later |
Who this process is for, and who it isn’t
Permission reviews can help wallet users who have connected to dapps, used token approvals, or granted NFT access and want to see what remains active. They’re also useful if you’ve stopped using a service but still see an allowance on a checker.
This process isn’t a substitute for securing a wallet after suspected device access, sharing a recovery phrase, or unauthorized transactions. Revoking approvals can’t reverse a loss or prove a dapp is safe. If funds are at risk, treat it as a broader wallet-security issue rather than assuming one permission change will fix it.
Bottom line
To revoke crypto wallet permissions, check connected sites and on-chain approvals separately, then review each approval on its network. Confirm the spender and transaction details before signing. Revoking costs gas and doesn’t undo past transfers. The aim is to understand and limit specific permissions, not to assume that a wallet is free of risk.
